Shockwave Therapy - uncovering new treatments

Doctors originally used shockwave therapy more than 20 years ago to disintegrate kidney stones in their patients, then learned that the therapy can also treat tendonitis, tennis elbow, heel spurs and other ailments. Equine researchers are still uncovering everything shockwave therapy can do for horses after it was initially and successfully used in Germany in 1996 to treat lameness. Shockwaves are high-pressure, low-frequency sound waves generated by a device outside the body and focused on a specific body site. When the shockwaves meet tissue interfaces of different densities, the energy contained in the shockwaves is released and interacts with the tissue, triggering natural repair mechanisms and stimulating bone formation and blood flow.

The shockwaves can lessen or eliminate pain and accelerate healing. New York trainer Rick Schosberg has a unique perspective on shockwave therapy. He’s used it on himself and his horses. “I’ve used it for myself for tennis elbow; it helped my elbow for 90 days,” Schosberg said. “With my horses I’ve used it a couple times on injuries and it did okay for minor injuries, soft tissue and saucer fractures. It probably knocked a third off the healing time but it’s expensive. You use it for at least three treatments over a month and a half, usually every two or three weeks. As long as it‘s not abused it’s okay. You can‘t run a horse within 10 days after you use it and you have to report it every time you use it (in New York) because it has an analgesic effect.” Shockwave therapy’s impact on horse racing could not have happened if it wasn’t developed for human patients first. And that happened by accident. During experiments with high-velocity projectiles, which were being used to smash ceramic plates, an employee at a company in Germany touched the plate at the very moment the projectile hit the plate. He felt something in his body akin to an electric shock, though measurements showed that there was no electricity present. That prompted German scientists to begin researching the possible effects of shockwaves on humans in the late 1960s. The first successful disintegration of a kidney stone in a patient by shockwaves was done in 1971. Fourteen years later, experiments were conducted regarding the effect of shockwaves on bones, leading to experiments on other parts of the human anatomy.

Today, shockwaves are the first choice of treatment for kidney and ureteral stones and has morphed into treatment for other medical conditions. Will equine medicine’s use of shockwaves follow a similar pattern? The first equine disease to be treated with shockwaves was proximal suspensory desmitis, an injury to the suspensory ligament which is a major cause of lameness. A year later, shockwaves were used on a horse with Navicular Syndrome, an ailment affecting the small navicular bone in a horse’s foot and the connecting ligament. The first use of shockwaves in the United States happened in 1998 with a horse with a distal hock joint and navicular pain. All the results were encouraging. “When we first started using it, it worked okay on lameness,” Iowa State University’s Dr. Scott McClure, DVM, a leading researcher of equine shockwave therapy, said. “At this point in time, it’s been well documented for tendon and ligaments.

A lot of people think it works for stress fractures. I think there are some joint applications which we’re learning more about. Soft tissue, too. It’s been shown to increase permeability of cell walls.” He believes that increased cell wall permeability could lead to drugs which are more effective attacking tumors. “There’s potential for a lot of applications,” McClure said. “I clearly don’t think we understand all of its uses.” There are two types of equine shockwave therapy: extracorporeal generated outside the body and focused on a specific area of a horse’s body, and radial pressure waves when an applicator is pressed on the horse’s body. “The two of them get lumped together, but they shouldn’t be,” McClure said. “They’re very different. Radial pressure waves have lower pressure and more shallow penetration.” According to Dr. Stephen Adams of Purdue University‘s Veterinary Teaching Hospital in a 2002 article, studies have shown that shockwave therapy is effective treating suspensory ligament disease, bowed tendons, ringbone, bone spavin, splints, fractured splint bones, sore backs, navicular syndrome and fractures not healing properly. “Initial studies show that about 75 percent of horses treated for these conditions show marked improvement following shockwave therapy,” Adams wrote, while noting that many conditions require a second treatment to produce optimum results. “Advantages of this treatment are that no drugs are used, and horses with chronic conditions such as bone spavin, chronic suspensory ligament disease and navicular syndrome can continue to exercise.

Frequently, improvement in lameness is achieved in horses where conventional treatments have failed. Shockwave therapy is used as an adjunct treatment for fresh injuries such as recent bowed tendons with the goal of reducing convalescent time and improving the outcome.” On its website, the University of Wisconsin-Madison’s Veterinary Medical Teaching Hospital suggests using shockwave therapy on horses suffering from: suspensory ligament injury, tissue calcification, fractures or joint ankyloses, fatigue injury to bone, back pain, navicular disease and bone exostosis.

McClure documented the effect of extracorporeal shock wave therapy (ESWT) on horses with unilateral forelimb lameness in a study he co-authored with Jessica Dahlberg, Richard Evans and Eric Reinertson which was published in the July 1st, 2006 issue of the Journal of the American Veterinary Medical Association. The study focused on five geldings and four fillies and mares with lameness.

Treatment by ESWT resulted “in a period of acute improvement in lameness severity that typically persists for two days. Thus, in horses undergoing ESWT, exercise should be controlled for a minimum of two days after treatment to prevent further injury.” The reason is that ESWT has an undeniable analgesic effect. “This has raised concerns that use of ESWT to treat musculoskeletal injuries in horses may, because of the analgesic effects, result in overuse of the injured limb, causing further injury to the affected part and posing a risk to treated horses and their riders,” the study said. “For this reason, racing jurisdictions in the United States and the Federation Equestre International have adopted regulations that require a 5-to-7 day period after treatment before the horse is allowed to perform.”

Regardless, the horseracing industry, one never known to embrace change and new products, has quickly come on board in using this non-invasive treatment on their horses. “Over the last five years, it’s dramatically increased,” McClure said. “The market is starting to saturate. There’s a lot of equipment out there. In 1988, I had the second machine in the country. I think the owners and trainers have taken the bit and run with it. They’ve been very aggressive with that.” Trainer Sanna Hendricks used shockwave therapy on her multiple stakes winning steeplechaser Praise the Prince after he suffered a soft tissue injury below the pastern while winning the 2003 Grade 1 New York Turf Writers’ Cup at Saratoga Race Course. “We used shockwave therapy on him, and he responded to it,” Hendricks said in an August 30th, 2004 story in the Blood-Horse. “I took the conservative approach with him. I gave him plenty of time to rest and recover and didn’t bring him back to training until February 5th with an eye on these races at Saratoga.” Praise the Prince not only made it back to the races at Saratoga, he won the 2004 Grade 2 A.P. Smithwick Memorial Steeplechase there as a nine-year-old. If that isn’t an endorsement for shockwave therapy, what is? But shockwaves should not be construed as a panacea.

Complications can occur with incorrect use, and McClure wrote, “The release of kinetic energy at interfaces of different acoustic impedances is crucial in planning ESWT. Shock waves must never be focused on gas-filled cavities like the lung or intestine.” Meanwhile, he’s back at work, doing new studies to see just what else shockwave therapy may help.

Guillaume Macaire - champion jumps trainer in France for many years

Guillaume Macaire is the current champion jumps trainer in France, a title he has held since 2003. He is based in the Charente Maritime region of France at La Palmyre racecourse. In 2006 he ran 231 different horses and regularly campaigns horses across Europe.

In 2006 he wrote a regular column in Paris-Turf in which he provided insight into his runners, discussed current issues in the racing world and would provide his opinion on sensitive subjects.

Guillaume, tell us how you came into racing?

I was born in Compiègne in 1956, I frequented the racecourse at an early age. My family wasn’t involved in racing but when I went, I fell in love with it. The pictorial, timeless side of Compiègne’s racecourse certainly had a big impression on me. After a short career as an amateur rider, I started training a few horses in Compiègne, exercising my horses on the forest’s sand gallops. I then moved in Maisons-Laffitte for 2 years, then fate drove me to the south-west of France, where races were well-attended,  I went to La Roche Chalais (Dordogne), I won races regularly, improved my results every year and discovered La Palmyre where I moved to12 years ago.

What are the advantages of training at Royan-la-Palmyre?

The variety of the region attracted me, as well as the track on the racecourse, there’s the nearness of the sea with big beaches, a pine forest and its paths in sand.
When I arrived, the racecourse’s sand track wasn’t really exploited; some trainers had worked on it, one of them Martial Boisseuil (well-known in Arabian racing) had had a certain amount of success from 1975 to 1990 without however leaving the borders of the Southwest of France. The facility has several jump tracks, hurdles, steeple-chase fences and cross-country jumps, and now English fences and hurdles, also the addition of sand in order to have a testing gallop reminds me of the English up-hill gallops. Here, horses must maintain their rhythm and use their back. This allows me to work in good conditions and to make really good jumpers.
I’ve trained in different places and always used the same basics, I adapt to the facilities offered by each place. Here, in La Palmyre, I use the quality of the sand as natural ground and make the best of it. But what is positive here would not be anywhere else, all the methods are good but it’s necessary to adapt oneself. Good horses make the difference.

Could you explain to me your training methods, what do you consider very important?

All the horses intended to work here are pre-selected on their pedigree, on their appearance and on their movement, as only these criteria will allow them to improve their technique in order to be more fluent and more successful. Due to this selection I quickly have an opinion about each horse, if it has “attached legs and a welded kidney” it’s not worth working any more.
I’m talking here about the horses I choose, those for which I assure an “after-sale service”; there are exceptions, other horses I wouldn’t have chosen are brought to me and they are still able to win races. According to the proverb “the good horses make the good trainers”.
I like some of my horses to come to training several times and go back to the fields to recover or simply to grow if needed. They arrive for the first time in the winter as 2 or 3 year olds. Before that, they are broken in and pre-trained by people I know, who know the way I want my horses to be worked. I like to do interval training, as I mostly train jumpers, it allows to build the horse’s fitness without killing it (it’s used a lot with humans anyway); I put bandages on all of them, they help the horse’s back to carry a rider in the right way and they help for the animal’s submission and relaxation.  In their first month of training, I school them 3 or 4 times a week in a closed arena with 4 hurdles and deep sand. Indeed my inspirational mentor Baron Finot, (a leading jumping trainer in the 1880’s) whose methods I adopted and adapted to our time and whom rich painting (gouaches and watercolours) I admire had said: “the good jumpers are those who are used to jumping when they’re young”.

The arena is compulsory to me, I say it’s like a pianist is nothing without his scales, he has to practice, so the jumping technique is the main point for a jumper’s career and we have to practice. Then, depending on the horse’s behaviour and its physical ability to bear the training it will either run in the spring of its 3rd year or it will go back to the field to take advantage of the spring grass and will return in the autumn stronger.

Just as each person is unique amongst the universe’s inhabitants, my jumpers are individuals. I train each one of them regarding how it responds in order to get a certain standard, the horse’s quality will do the rest. My work is to form them as studious pupils. The trainer’s art is to find good horses and to find quickly enough if they’re worth it or not. 
Feeding is of prime importance in a racehorse’s life; it’s important to respect nature. For this I have all my horses on shavings and the racks are always full of hay (from the area of Crau) which avoids them to be bored in their stable and is a great help for proper digestion. They also eat oats and in the morning and bran mash in the evening (they have it even when they’re away racing, as I own several pressure-cookers).
Another essential thing to me is the horse walker, it replaces the lunging work that was formerly used a lot when people had time. I was the first trainer in France to buy one. It is surely not an economy of staff, but allows the horse to work muscularly and mentally freely without a direct constraint from the rider’s weight and hand.
The walker is used daily for different purposes, a horse that needs to let off steam before concentrating on the work for the track, a horse with a back problem or a horse that needs to recover after the races.
 I use a scale, horses are regularly weighed, especially before and after a race in order to know their exact condition. The optimum weight is a precious indicator of the state and health of the horse.
The work list is my puzzle for every day, adapting every horse with his/her rider then adapt them to each string according to the work required. I have as well to adapt to the new horses, their progress whilst keeping their objectives in mind.
No one can imagine how much the quality of a regular and constant work made in the morning is related - and improves - the final result.

Tell me about your staff?

My team consists of about 30 people; it’s a pyramid system whereby each person has their place and their function from the bottom to the top. In the summer we attract English, Irish and now Swiss riders who combine their holiday with a French racing experience. Noel Williams, Alan King’s assistant, spent some time with us last year and seemed pleased by what he discovered here and by the French racing customs, it complemented what he already knew. It is interesting for everybody to exchange different points of view as each country has its own habits.

You like to run horses in England, why?

I consider the level of competition is very high in Great-Britain, our best horses are sold and cross the channel when they’ve shown really good things there. There’s a conquering side in winning races abroad! It is the circumstances that brought me to England with Jair du Cochet, who won a Group 1 race (the Welsh Finale Junior Hurdle at Chepstow) first time out there. He didn’t pass the vet twice, so, pricked in my pride I wanted to show he was a good horse in order to prove my honesty. He adapted very well in England and ran only there, with a certain success. It is impossible for a horse to run everywhere all year through - except for The Fellow who was an extraterrestrial as he had won the Cheltenham Gold Cup and the Grand Steeple Chase de Paris. I take an outstanding pleasure running in England as this for me is the homeland of the jumping races, a consecration for every trainer to win over there. But I want to go there only with a first class chance or if an English owner of mine wants to see his horse run over there. If I have good entries for a horse who knows Auteuil I’ll stick there.

What are your hopes for 2007?

I hope we can continue where 2006 left off and to find more time for my favourite hobby – painting horses. 

Bendik Bø - the Swedish trainer and inventor

When he rode his first race, the horse was a year older than him. They did not win. ”I never was a very talented jockey”, he says. He has many other talents though. The Norwegian Bendik Bø (39) is a successful racehorse trainer and inventor, based in Sweden. 

He was never afraid to try his hand at new tasks. He was shoeing his first pony when he was only 14 years old. ”I had been watching the farrier at work and helping a bit”, he remembers, ”one day he did not turn up – so I did it myself, secretly of course, but it was fine.” Some thirteen years later he was a full time farrier himself. ”I had around 200 horses on my list”, he recalls, ”just shuttling between the stables on a three wheel moped. My business was going well, one year my turnover was 1.7 million kronor. It was hard work, but the fine whisky was too easy to come by. Drink nearly ruined my life”. 

 
”So, five years ago I sought professional help, got rid of the drink, began developing my main invention, and went into training”. He now handles one of the biggest strings in Scandinavian racing, training nearly 80 horses at Täby Galopp. At the beginning of last year, he had eight.
 
Bendik Bø’s main invention – it is not the only one – is a vibrating floor for horseboxes, to give the horse massage from the ground. He first got the idea when working for a trainer in Italy in 1992. They had the very useful sprinter Prairie on the team. ”Though he had tendon problems”, Bø recalls, ”and the vets told us his career was over. I felt we could give him a chance, and even had a bet with one of the vets that we would get him back on the track and win a certain amount of prize money with him. We did get him back on the track, and he won five races for us in Sweden the following season. We then took him to Italy, but his problems came back. After some improvement, we could train him though, and entered him in a Listed race in Milan. I was driving the horsebox, doing a trip of 350 kilometres. It was an old horsebox, very stiff, and not a very smooth drive at all. We could feel a lot of vibration on our way to Milan. On arrival, I noticed that the horse was moving, and clearly feeling, so much better than I had ever seen him. He won the race, running 1200 metres in 1:07.and beating a good ex-English horse called Reference Light, who was second in a Group Two the same year.”  
 
”When driving back from winning that Listed event, I remember thinking how convinced I was that the ”vibrating” box ride had something to do with Prairie’s performance that day. And I said to myself, ’I must find a way to get this box into the stable...” he says. Prairie, who had been a champion in Sweden, also ran fourth to Special Power in the Premio Certosa (Gp 3) at San Siro. Bø won the bet with the vet.
 
The idea of a vibrating floor was to be experimented with, and pondered on, for nine years before Bø and members of his family back home in Norway started working seriously on the project five years ago. ”During those years, my life took some twist and turns”, he explains openly, ”I was heading in the wrong direction. I always wanted to return to a life working closely with horses. Alcohol is a very, very dangerous friend, however, and could easily have ended all my ambitions. Admitting himself to a clinic in Norway for seven weeks, he came out a tea-total, and very determined young man. ”Some may have said I was not going to get away from the drink”, he says, ”but I did, and I decided to put my life to better use. The same year we decided to give the vibrating floor a real crack too. My house was tidy and it was time get the drawing board out.”  
 
From starting out as an amateur rider, to be just a run of the mill jockey, then an inventor and very good trainer, Bø strikes us as a man whose strong will has pushed him through storms where many would have turned back and gone back to more conventional life than working with racehorses in Scandinavia. After all, making a decent living from thoroughbreds in Norway, is not much easier than making a living from skiing in England. That was also why he turned his back on the sport when he was 16 years old. He was young but had been involved for years and already saw how tough it would be, financially, to make it.
 
A career in the saddle was always going to be a ride against all odds. Bø is 1.78m tall, and his lowest riding weight was 57 kilograms. ”You just can’t live like that for very long”, he says, ”and after riding about 20 races, and no winners, I left the sport and took an agricultural education instead. When that was completed I was riding out from time to time, and did some farrier work to make extra money – but eventually I left racing to work on a cow farm in Norway. It lasted just a couple of years. I was soon drawn back to the horses, and to racing”.  
 
His ticket back into horseracing came when he was offered an apprenticeship with trainer Trond Hansen, one of the leading trainers in Norway - now based in Germany. ”It was a good time to join his yard”, he says, ”as we had some classy horses, like Salient, who had been bought out of Dick Hern’s team for 110,000 guineas – then a record price - at the 1985 Tattersalls Horses in Training Sales in Newmarket. He was previously owned by the Queen, by the way, and was a top horse in Scandinavia. We also had a 2000 Guineas winner and a champion sprinter the same year.”  The inspiration was back, although it meant riding out in 20 degrees below at wintertime, hardly eating at all, and sometimes travelling about ten hours by horsebox to race meetings in Sweden and Denmark. ”My interest was back, though my race riding was still not going all that well...”
 
A winner, at long last
 
Some two years later, a Swedish jockey, of the opposite sex, persuaded Bø to come with her to work at Täby Galopp outside the Swedish capital Stockholm, where racing is considerably bigger than in Norway. ”At long last”, he recalls, ”soon after moving, I rode my first winner. I was 20 years old, my stubborness got be to the winners’ circle – but it had taken some time!” 
 
A few more winners followed, and Bø also began riding over jumps. Working for Olle Stenstrøm, who trained quite a few good hurdlers and chasers, the young Norwegian was now partnering winners on a more regular basis. He moved on to work for Claes Bjørling, who took horses from Sweden to Italy. Bjørling also bought horses out of sellers in England and campaigned them successfully in Italy. Bø rode at many of the Italian courses. He enjoyed success at Capannelle, Pisa and Treviso, and also rode at Cagnes-sur-Mer in France. 
 
”One of our best jumpers was a horse called Obeliski”, Bø tells us, ”Mr Bjørling got him out of a claiming chase at Southwell, when his official hurdle rating in England was just 128. I rode him to be fifth in the Italian Champion Hurdle. I remember being very proud of having beaten the high class English hurdler Staunch Friend and Steve Smith Eccles in the race. Not bad you know, on a cheap claimer. My boss also claimed a horse called Bighayir, who had won ten races for Martin Pipe, but he did not jump well enough when we took him to Cagnes-sur-Mer.”  
 
The French course does, like Bendik’s boyhood city, sit by the seaside. Though that is the only thing Cagnes-sur-Mer and the city Larvik in Norway has in common. 
 
Bø grew up in Larvik. He is by no means the only man with a thinking cap fostered in the small seaside city. Larvik’s most famous son is Thor Heyerdahl, the anthropologist who sailed the raft ”Kon-Tiki”, made of Balsa wood, from Peru across the Pacific Ocean to Tamoto Islands, to prove that ancient Peruvians could have reached Polynesia in this manner. In 1947, Heyerdahl and his five companions made the 8000-kilometre crossing in the primitive vessel, taking 101 days.
 
Growing up in Norway, let alone Larvik, without knowledge of Heyerdahl’s name and work is virtually impossible – but Bendik was not interested in anthropology. He liked horses better. He turned up at Hovland Ridestall, the local riding school, when he was ”seven or eight years old”. He had no money in his pocket for riding lessons of course, so instead he struck up a deal with the owner of the place. Bendik mucked out boxes without being paid, and was given sporadic riding lessons in return. After a few years of this, he and his schoolmates were given responsibilities in the stable, owned by Knut Rimstad, who combined running a riding school with racing a small string of his own horses at Øvrevoll racecourse outside Oslo. The boys also travelled with the horses to the races. ”Some of Rimstad’s racehorses were even used for lessons at the riding school”, Bendik recalls. 
 
The ambition was clear enough; to become a jockey. And the teenage boy was never short on imagination. When a replacement rider was needed for a horse in an amateur race that very evening, at short notice, he got his friend Roy Arne Kvisla out of the classroom at school. Kvisla, who is now a trainer in Lambourn, had never ridden in a race but he was old enough to do so. Bendik was not, so he knocked on his mate’s classroom door. It was a daring move, as behind that door they were having an important test in chemistry. Bendik told the teacher that Roy’s mother was ill, and that he had better come along with him. The teacher agreed. The boys headed off to the stables, from there to the races at Øvrevoll, where Kvisla rode the horse – and won the race. Fortunately, the teacher never bothered with the racing results when browsing the morning papers!
 
Bø himself rode his first race at 15, the minimum age for race riding, partnering a veteran called Federation. The horse was a year older than the rider. ”We finished fifth”, Bø tells us, ”I kept on riding, and over the years I have partnered over 80 winners on the flat and over jumps. But to be honest, I never was very good as a jockey”. 
 
He rode his last race in 1994, when experiencing a bad fall on a hurdler that broke both front legs during a race – on the flat. ”I just heard a solid bang when we went down”, Bendik recalls, ”I took a heavy, heavy fall and that was it. No more race riding for me. I decided to quit while still in one piece.” His riding career, which had began on a 16-year-old plodder at Øvrevoll when he was 15, thus ended with an incredible and nasty fall on a jumper at Täby Galopp when he was 27.
 
To this day, Øvrevoll is the only thoroughbred venue in Norway. Harness racing is dominant, and the country has no more than 380 active thoroughbreds. This season, Bendik Bø has taken over the stable of retiring Michael Kahn, many times champion trainer in Sweden. This move puts him in charge of close to 80 horses, more than a fifth of the racehorse population in his native Norway. And he is still mucking out boxes – ”we’ve got to work”, he smiles. 
 
There is an active exchange of horses, trainers, jockeys and staff in general, between the Scandinavian racing communities. In particular between Norway and Sweden, and Bø has been back and forth between the Oslo region and the Stockholm region a few times. In 1986, when he travelled east to pursue his career in the saddle, it led to a life as a farrier, making good money, but also to a lifestyle that led to too much partying and drinking. The tall, slim and happy Norwegian was never violent when drunk, just having a good time and often playing his violin to entertain the party. 15 years later he was heading back home, to get rid of ”a dangerous friend” as he calls it, to cure his alcoholism. ”I woke up one morning feeling really fed up with my life”, he reflects, ”it was time to take a turn”. 
 
Harness racing
 
After travelling back to Norway to sort out his problems with drinking, which his motivation helped him do in less than two months, Bendik took out a license to train horses there. He was based back in his hometown Larvik, training a small string. ”I wanted to work on the vibrating floor and do more research with active horses”, he says, ”and with other family members I set up the company Vitafloor. My idea was to get horses with problems, treat them, use the floor to give them effective massage, and train them for racing. In order to get enough such horses, and get enough experience with racing horses that had been using the floor, I had to turn to trotting. With only five to six thoroughbreds, I had over 20 trotters in my stable. I had trotters racing at all the big tracks in Norway. It all went relatively well and we even shipped a horse to win a valuable race in Sweden. I am convinced that my years working with trotters is very valuable today.” 
 
Bø trained thoroughbreds side by side with warm blooded trotters, and trotters of Nordic race, often described as ”cold blood horses”. He says that getting as much experience as possible, with a variety of individuals, is how to become a good horseman. As long as you pay attention of course. After five years in Norway, he moved back to Sweden for the 2006 season, to train at Täby Galopp. His initial team there was even smaller. ”I took over from Roy Arne Kvisla as he left for England”, he explains, and I had eight horses to train.” At the turn of the year he had 42. He saddled 26 winners from 118 runners, for a healthy 22% strike rate.
 
It helped him tremendously of course, that he revitalised the 10-year-old sprinter Waquaas to such an extent that the gelding won three races on the bounce early in the season, including a pair of Listed contests; the Taby Vårsprint and the Norsk Jockeyclub Sprint. Bø was off to a good start on his return to Sweden. 
 
Today, he is in charge of the biggest string in the land. There is no spare time, ”We employ ten full time, plus use some freelance work riders”, he explains, ”but I work seven days a week myself, as does my partner Mette Kjelsli. What spare time I get is often dedicated to my inventions. But you know, I can also think through those ideas when on an eight-hour drive to the Danish or Norwegian Derby meeting!” 
 
”We race year round here”, he explains, ”on turf and dirt, and I divide my horses in two groups, the best horses are active through the spring, summer and early autumn, while the lesser lights will be racing mainly at wintertime. Taby Galopp owns a farm close to the track, where I rent some boxes. This is where we send the horses for breaks, though some also go back to their owners’ farms for rests”, he says. His string consists approximately of 60 per cent imports, mainly bought in England, and 40 per cent Scandinavian breds.
 
Simple solution the beginning
 
Returning to the inventions, Bø tells the fascinating story about how he took the first small steps towards what today is the highly sophisticated Vitafloor. 
 
”I took a big board, attached an engine under the board, placed the whole thing of four blocks of wood shavings, and switched the engine on”, he tells us, ”I tried walking on it, lying on it and feeling the massaging effect. This was just my first prototype of course, but other jockeys used this vibrating board too, just to get a relaxing massage after riding. It was obvious that it would not be quite that simple but at least I had discovered that my theory was working, to a certain extent. So, I kept on thinking about solutions for many years.” Today, Bø has sold the Vitafloor to various trainers, both of thoroughbreds and harness horses, and veterinarian clinics in Scandinavia, and recently his company exported the first floor to Dubai.  
 
Bø has also invented elastic reins. ”When the horse breaks into a gallop”, he explains, ”he will always stretch his neck out, and pull for a bit more rein. No rider has a hand quick enough to accomodate the horse during these few strides, to give the horse a smooth communication through the reins. I had noticed how, at the start of many a race, horses and riders were not in full harmony and perfect rhythm – they were not working as a team, and the horse was often tugging sharply against the bit when trying to find his balance. Therefore I made elastic reins. It is very simple, the rein runs in an s-shape, with elastic bands attached straight across. This means that the horse gets a bit more leeway and freedom when gaining his balance as he picks up speed – but when he pulls harder, the reins go to full stretch and take over. The elastic band is only a matter of a four to five centimetres but that is enough to make quite a difference.”
 
He has sold ”a couple of hundred” of these reins, ”I produce them myself”, Bø says. And when he got his first cat, he soon became fed up cleaning the cat case, so he invented a cat case that could be cleaned in 15 seconds. ”I have patented that too”, he explains, ”but it has never been commercially marketed. I am working on more important prototypes for the equestrian industry right now, the cat case was just for fun, really”. 
 
At a track like Täby Galopp everyone knows everyone. ”There are about 20 trainers based here”, Bø tells us, ”and the number of horses stabled at the track is always around 400. The country has about 1400 racehorses. Swedish racing has been struggling, that is no big secret, but there is a positive will to move forward here, and people work well together”, he says. 
 
On the racetrack committee
 
The racecourse management has formed a track committee, with meetings every two weeks. Bø is a member of this committee and he explains; 
 
”I represent the trainers, there is also a jockey on the committee, as well as the general manager, the head groundsman and a veterinarian present. We meet for lunch twice a month, exchange ideas and discuss how best to improve the racecourse – both for training and racing. I enjoy this, we are all learning and it is important to take part”. 
 
Racing takes place on an American style track at Täby, with a turf and dirt course, where they manage to keep racing going in the winter, by adding salt to the dirt track and by harrowing the track 24 hours a day through the winter months. The dirt track is 1742 metres, while the turf course is 1595 metres round. There is also an inner, figure of eight, steeplechase course.
 
”This may not be Newmarket or Chantilly”, Bendik says, ”but the training facilities are good, and remarkably consistent. I rarely feel the need to go to inspect the track in the morning before working my horses. And you know, small as this team is, we have a hard working and dedicated group of people here. But it’s also costly to keep racing going 12 months a year. I know one of the guys working night shifts on the harrowing, and he just told me that he burns around 500 litres of diesel every night. That’s a lot of money you know!” Racing goes ahead in freezing temperatures, as low as 10 to 15 degrees Celcius below zero, when riding weights are put up by a couple of kilograms to allow more clothing for the riders. 
 
When asked about racing horses on dirt and turf, Bø is quick to point out that ”you get surprises all the time, but there are dirt type runners and there are turf type runners. I do not think any horse can be equally effective on both surfaces. I prefer turf, but when I have a horse winning a nice race on dirt, I love the sand”, he smiles, ”and without it – where would we be?” 
 
He took two runners to Lingfield Park in England last November, when his domestic Listed winner Maybach finished tenth in the Churchill Stakes. ”It was an experiment”, he reflects, ”but Maybach ran better than his finishing position may suggest, beaten just 6 lengths behind Nayyir, when carrying just two pounds less. After all, Nayyir used to be a Group One horse. My other horse, the Argentinean bred King Nov, was unplaced in a competitive sprint handicap. We felt that he was given a tough weight bgut he was not disgraced, and I went home believing that we can take horses to England and win. I was very impressed by the Polytrack, it is far less demanding than our conventional dirt track. We will be back but, mind you, taking these two horses from Stockholm to Lingfield did cost 70.000 kronor all told (approximately £5000)”.  
 
When Maybach won the Listed Nicke Memorial at Täby two months earlier, the reward was nearly £11,000, which is half of what Nayyir earned in the Churchill Stakes but more than the runner-up’s share in the Lingfield contest. And for the Nicke Memorial, Maybach was simply walked for about three minutes from his trainer’s stable to the paddock. 
 
”The best races in Scandinavia have good purses”, Bendik explains, ”so it makes little sense for us to ship our best horses abroad during periods when we have opportunities for them at home.”
 
As an example, the Stockholm Cup International and Täby Open Sprint – both Group Three status – were both worth €88,398 to the winner last year. On the same Sunday, Longchamp staged their ”Arc” trails, including the Group Two events Prix Niel and Prix Foy, both worth only €68,400 to the winner. 
 

Still, Bendik Bø hopes to be able to campaign more horses internationally, from his base at Täby Galopp. ”We have the knowledge, we have the horses, and we have the ambition, also among the owners, to do just that”, he says, ”and I certainly have the will”.  We knew that. 

Feeding during early training - how to minimise problems

Most of the current crop of 2yo’s will now have been broken and are in the early stages of training proper in readiness for the forthcoming flat racing season. This period brings with it numerous problems for trainers and their staff, such as horses with high muscle enzymes, episodes of tying up, respiratory infections, various lamenesses and other skeletal problems or simply over exuberance.

Whilst such issues have many contributory factors, a good basal diet, with carefully selected extras can help to minimise some of these niggling problems. Overfed horses can become fat or too excitable During breaking, and pre- and early training the emphasis from a nutritional perspective should be on adequate but not excessive energy intake, whilst ensuring that a balanced diet is provided in terms of vitamins, minerals and quality protein. An overfed horse becomes either fat and so difficult to slim down for racing, or badly behaved and excitable, and thus more prone to injure itself or its rider. To avoid excitability, good quality hay or haylage fed in increased amounts will not only help to reduce the reliance on concentrate feeds, but may also reduce ulceration, especially in horses in their first season of race training. There are several concentrate feeds manufactured specifically for horses in early training or during a ‘lay off’ period. These are generally lower in energy than racing feeds, but still ensure an adequate intake of quality protein for young horses and provide a more concentrated source of vitamins and minerals, given that the intake of feed can be quite low at this time. Sometimes a more economical alternative to these tailored feeds would be a good quality low energy mix or cube, manufactured for the mainstream horse market.

However, reassurance should always be sought from the manufacturer concerned on the suitability of the main ingredients, including the protein and fibre sources and vitamin and mineral level for a horse in pre or early training. An further advantage of these two concentrate feed types for this stage of training, is that the energy provided is derived largely from digestible fibre and sometimes oil, with less emphasis on cereal starch. This is potentially beneficial for behaviour, and also for horses with a predisposition for tying-up or ‘set fast’. Not every raised muscle enzyme is a ‘set fast’ Raised blood levels of the muscle enzymes AST (aspartate aminotransferase) and CPK or CK (creatine kinase) are common place during early training. These enzymes are present at much higher levels in muscle cells than other tissues and therefore their leakage into the blood is considered indicative of muscle damage. The complication is that although muscle damage can result from an ongoing metabolic issue such as tying up, it may also occur as the result of transient over exertion. High AST and CK’s in blood are not always an indication of a horse having tied up and some horses that exhibit these blood results in the early stages of training will often work through it as training progresses.

Care should obviously be taken with horses, who show clinical signs of having tied up on one or more occasion. For such horses, diagnosis early in the season is beneficial, as their diets can be scrutinised more closely and key changes implemented that can in many instances reduce the severity or frequency of such attacks. These horses will often benefit from being fed a basal ration that is very low in starch (typically less than 15%) and so equally will need to be high in digestible fibre and oil to ensure adequate energy intake during training. Current research into tying up cannot yet explain why this dietary change helps, but widespread experience suggests that in many instances it does. Stephanie Valberg from the University of Minnesota suggests that it may be due to an effect on stress and the change in diet results in these horses becoming less ‘anxious’. However, trainers have in the past highlighted practical problems with this approach.

Some have reported that long-term palatability may be a problem with this type of diet, as horses seem to instinctively like the sweet, cereal rich coarse mixes and cubes, typical of traditional racing feeds. Measures that can be taken to avoid such problems include: 1. Identify problem horses as early as possible and adjust their ration to prevent them becoming accustomed to traditional racing feeds. 2. Feed 4 or 5 smaller meals per day rather than 3 larger ones. 3. Mixes are often more palatable than cubes 4. Some unmolassed sugar beet can improve palatability Most racing diets need supplementing with salt Electrolyte provision, including sodium, potassium, chloride, calcium and magnesium is an important dietary aspect to evaluate for all horses in the yard, not just those that tie up.

Racing diets generally meet and exceed the requirements of potassium and chloride, which are two of three the main electrolytes lost in sweat. The third, sodium, is in my experience never present in sufficient quantities in proprietary feeds for horses doing more than light work. This may be largely due to manufacturing constraints. However, sodium is easily supplemented by adding ordinary table salt daily to feeds (typically between 25-75g per day depending on work load). Whilst calcium and magnesium intake is usually adequate, the calcium to phosphorus ratio of the diet may not be optimal, especially if feeds are top dressed with oats.

It should also be recognised that, there exists quite marked differences between horses in their ability to absorb electrolytes and for this reason a creatinine clearance test can be useful in the further investigation of problem horses. This test (which involves taking paired blood and urine samples for analysis of the major electrolytes) helps the vet and nutritionist to take account of individual variation in electrolyte absorption and excretion and to modify the diet accordingly. Vitamin E intake can be low in some pre-training diets Vitamin E and selenium content of the diet should also be studied carefully. Racehorses that repeatedly tie up are not necessarily deficient in these two micronutrients, but may have a higher requirement due to increased free radical production. In my experience, selenium is usually present at appropriate levels in most racing rations, however the level of vitamin E provided can often be lacking.

A higher daily intake of 1600-2400iu per day for a typical horse in training has been recommended in the scientific press. The range in vitamin E content of racing feeds is quite wide, typically between 250iu to nearly 500iu per kilogram of feed. So a horse in full work may receive anything between 1500 to 3000iu per day, excluding forage and supplements. However, many trainers rely on the use of non-specialist low energy feeds during early training and these are obviously fed at a much lower level of intake compared to racing feeds for horses in full work. This could therefore result in vitamin E intake during this period being nearer to 1000iu per day. Poor hoof condition is a common gripe for trainers and farriers Poor hoof condition is another common problem that develops in early training and which can often deteriorate as training progresses.

Whilst there are many conformational and biomechanical factors that contribute to poor hoof condition in Thoroughbreds, nutrition is an area that should not be ignored. It is true to say that most of the relevant nutrients such as quality protein, calcium, zinc, methionine and fatty acids are supplied in a typical racing diet. However, the micronutrient that has received most attention in the scientific literature with respect to improving hoof horn quality is biotin. Biotin, a B-group vitamin, is generally provided at a level of intake in most racing feeds that easily meets a horse’s basal requirement. However, the daily intake reported to improve horn quality is typically 10-20 times higher than this.

Biotin has been reported to improve hoof horn quality when fed daily at levels between 10 and 20mg per day. Patience however, is required with biotin supplementation, as benefits are unlikely to become apparent for 6-9 months. But remember that biotin is worth feeding for 12 months of the year – as the horn grown in the early winter will be raced on in the spring and summer. Getting the basics right for respiratory health Development of respiratory disease during early training is also a commonly encountered problem. I always compare a yearling’s first venture into a training or pre training yard to a toddler starting nursery for the first time, which can often involve consecutive colds and associated bugs for the first year or more.

Indeed, the adaptive part the mammalian immune system is strengthened through exposure to different infectious challenges. It is not surprising therefore, that avoiding some form of respiratory disease during pre or early training is an uphill struggle. Numerous nutrients that may support the immune system have been investigated by scientists in man and other species, such as glutamine, antioxidants including vitamin C and E, probiotics, prebiotics, omega 3 fatty acids, adaptogenic herbs, whey protein and others.

The vitamin C level in the fluid surrounding the lungs is reportedly decreased in horses suffering with Recurrent Airway Obstruction and other types of airway inflammation (e.g. bacterial infection), and some vitamin C supplementation can be warranted where a problem is identified. Glutamine is a major fuel source for cells of the immune system and whilst the merits of supplementation in horses have not been proven, a fairly recent study indicated that horses infected with the equine influenza virus exhibited a significant decline in blood glutamine 41 days after exposure. There may well be other nutrients amongst those cited above that could prove useful, however there are few if any products (or ingredients) that have extensive and unequivocal scientific evidence to support claims that they ‘enhance or boost’ the equine immune system. Before turning to nutraceuticals for all the answers, some fundamentals can be addressed.

Good clean bedding is essential, as are well-ventilated stables and clean forage. Whilst American hay has a good reputation for being clean, with very low mould and yeast counts on analysis, many trainers prefer to use English hay for early training and some will use it through the season. Unfortunately, our variable climate means that producing consistently clean hay can be difficult. Whilst haylage is a viable alternative to hay, as the process of fermentation keeps the level of mould and yeast to a minimum, it is not infallible and haylage that has been produced badly, or which has become contaminated is a serious issue.

I would recommend that before committing to a batch of hay or haylage, some basic analysis of moulds and yeasts is money well spent to ensure that potential respiratory challenges from forage are minimised. Total mould and yeast analysis cfu/g from forage sampled from racing stables Total Moulds Total yeasts Thermophilic spores Hay – English Timothy 270 150,000 150,000 150,000 <10 Haylage – English Rye 10 <10 30 * No visible spoilage was seen in any of these forage samples Retention of calcium is reduced in early training Finally a discussion of the problems of pre and early training would not be complete without reference to bone. Many of the problems encountered at this time relate to changes in bone strength and density during training. When a racehorse enters training for the first time their cannon bones have been shown to go through an initial period of demineralisation, which reaches its greatest severity at about 60 days into training (US based study). Remineralisation then occurs as training progresses.

The initial demineralisation phase results partly as part of the remodelling process but also as a result of a change in the nature of the diet (less forage and more cereal), as the horse moves from stud to training or pre training yard. Current thinking follows that adequate calcium content in the diet is especially important during the initial demineralisation phase, as the horse’s ability to retain calcium in the body seems to be reduced. Attention to the calcium to phosphorus ratio of the diet is also vital, especially if top-dressing with cereals. The dietary magnesium content should also be evaluated in this respect as it is sometimes overlooked. Silicon supplementation shows some evidence of efficacy in reducing some injuries in racehorses but its powder form as sodium zeolite has limited its use. A liquid form is now available and although promising, as the intake per day is very low, it does not as yet have a scientifically proven track record.
