Building a stronger racehorse with dynamic mobilization exercises

By Kimberly Marrs

Yoga, Pilates, cross training, pre-habilitation—whatever you prefer to call it—are strength- training exercises also known as dynamic mobilisation exercises, which can greatly benefit your racehorses. You can perform these exercises on your horses to help with correcting posture, gaining  strength, flexibility and core stability. All of these positive gains will help a racehorse be more  balanced in his movements. Incorporating these exercises daily will of course help alleviate tensions in the body that could potentially turn into problems or pathologies down the road, while reducing the risk  of repetitive use injuries. 

The concept is the same as cross training in human athletic training. A horse also needs several types of exercises to help keep the body balanced and able to handle the intensity of competition, reduce performance issues and aid in the body's recovery after competition. As human athletes have known this, one size—one exercise—does not fit all. The body's systems all need to be challenged to produce an all-around balanced athlete. This logic needs to be addressed with training racehorses as well. Regular sessions of these types of exercises will result in the improvement of the horse's posture and ability to carry a rider in a balanced way. A horse with good posture will allow for optimal performance for a longer period with less exhaustion and muscle fatigue. 

Muscles at work 

A dynamic mobilization stretch is mostly done using a bait and are referred to sometimes as  carrot stretches. While performing a stretch, certain muscles are activated so that they move, and stabilise the intervertebral joints. 

Then the activated abdominal muscles help to bend and round the back. This is especially important for a racehorse unlike horses who are trained to carry a long low frame, which will help them engage their body’s core. Racehorses will tend to train with their head high and with a hollowed back.  Over time, this can predispose a horse to back pain, kissing spines, lumbosacral issues—all  which can then lead to compensatory issues. 

If you take a series of two-year-old thoroughbred  racehorses, a high proportion of them will have radiological evidence of kissing spines, and  quite a lot will have associated back pain.

So joint stabilization is particularly important to help with improving performance and the  prevention of injuries. Research has also shown that with regular performance of these exercises, the equine back becomes enlarged. Subsequently, this will strengthen the back muscles and enable the horse to carry the rider more efficiently with a lessening of back stress. To demonstrate this, I have a person put a 11 to 22 kg sack of feed over their shoulder. Next, I have them walk between 7 to 9 metres as they would normally walk. Then I have the person stand up straight, hold in their core (abdominals) with correct posture and walk back 7 to 9 metres. The difference is usually substantial, and the person can feel less stress on the limbs with a straighter and more balanced way of moving. Now they get why the horse's core strength is so important! 

Get started on a routine

I have been doing these for some time and have seen amazing results in my horses' overall posture, toplines, reduction of back pain and suppleness in their musculature. To get started with your dynamic mobilisation routine, keep in mind that performing these exercises are safe. Do take care though: If your horse has a musculoskeletal or neurological issue, clear it with the vet first before starting dynamic mobilisation exercises. Also keep in mind that many of these exercises are also utilised in rehabilitation from injuries. 

When implementing these exercises, ensure the horse follows the bait in a nice smooth manner, and get the horse to hold the stretch. This can sometimes be easier said than done. Some horses will try to snatch and then snap their head back forward. So be patient; there is a learning curve with each individual horse. The more you perform these moves, the better you’ll get, and the smoother the stretches will become.





Basic daily routine 

On a daily basis, I perform the following six exercises, and my horses love it! There are certainly more exercises you can add into this series if you choose, and they can definitely be tailored to an individual horse’s needs. 

1. Neck to Tail stretch

  1. Neck stretch: I get the chin to follow the carrot to the back of the horse's flank. I try to  get the horse to hold 10 seconds, and I will repeat this three times. 

  2. Lateral side bend: With the chin bowing around my body, I lead the carrot towards the back leg. I get the horse to hold the stretch for 10 seconds and repeat two to three times. (Note: Repeat these stretches on both sides of the horse.)

  3. Chin between front legs: I use the carrot to bring the horse’s chin down between its front legs and hold the stretch for 10 seconds; I will do that two to three times. 

  4. Neck extension stretches: I will get the horse to stretch out its neck and hold for 10 to 15 seconds, or even longer. 

  5. Belly lifts: I also perform belly lifts while grooming at least 2 times for 15 to 25 seconds daily. 

  6. Butt tuck: I run both hands along the top of the tailhead and scratch to get the horse to tuck its butt under and bow the back to open the spinous processes, elongating the back and hind-end muscles. I will try to get the horse to hold the tuck for 10 to 15 seconds and will repeat.

2. Lateral Side Bend stretch

3. Under the leg neck stretches

4. Neck extension stretch

5. Belly lift

6. Butt Tuck

As you regularly implement dynamic mobilization exercises in your routine, you will achieve a more flexible, stronger horse while helping aid in reducing a lot of common issues we encounter while training. When done properly, these exercises will help keep them sound and able to perform to the best of their abilities so that they can have longer careers, on and off the racetrack!

Testosterone - More than just muscles

By Dr Catherine Dunnett

Testosterone is a hormone that has received a lot of attention in the media, mostly in a negative context due to its historical doping use in humans and animals.  When we think about testosterone we associate it with muscle building and aggression. There is, however, so much more to testosterone, which I have uncovered in recent weeks.  

Testosterone is a hormone that is produced naturally by colts, fillies and geldings in varying amounts. Colts show a naturally higher circulating level of testosterone than geldings and fillies. Testosterone is classified as a steroid hormone, and it has a characteristic ring-like structure, being ultimately derived from cholesterol (see Figure 1).  It is produced primarily in the testes in colts, but perhaps surprisingly also in the ovaries and adrenal glands, which explains the natural levels found in fillies and geldings.  

Testosterone is responsible for the development of primary sexual characteristics in males and also drives muscle development. However, it is also converted to dihydrotestosterone and estradiol, both of which have interrelated functions.  Estradiol has a major role to play in the brain and in maintaining cartilage integrity and bone density. Interestingly, neither synthetic testosterone, nor dihydrotestosterone can be converted to estradiol; and so this is likely to have negative connotations for bone when the muscular strength is affected through synthetic testosterone administration.

Testosterone also has an effect on blood by stimulating the production of red blood cells. It is also reputed to have a psychological impact beyond the well-recognized effects on sexual drive and aggression.  In people, testosterone is reported to boost confidence and positivity in some circumstances, as well as dominance and competitive success.

Testosterone synthesis is not straightforward and forms part of a complex series of pathways where cholesterol can be converted to one of many possible steroidal substances. How much testosterone is produced is controlled by a series of hormones and various feedback mechanisms. Stimulation of testosterone synthesis would be difficult to achieve non-medically, yet it has been a target of supplement manufacturers in humans and horses over many years.  Ingredients such as gamma oryzanol, fenugreek, ginseng, velvet antler, horny goat weed and others have been offered as having a positive effect on testosterone synthesis. Most of these ingredients, however, would have little in the way of science to support this and even where some published studies exist. For example, for extracts of fenugreek, there is significant controversy over the validity of the results. Additionally, one can never be sure that a positive result in one species will deliver the same in another species due to differences in digestion and absorptive capacity, as well as physiological differences.  As far as I am aware, there are no ingredients or products that have been unequivocally shown to boost circulating testosterone in horses.

Rice bran oil

One such ingredient—gamma oryzanol—is a nutritionally important constituent of rice bran oil and is normally present at a level of about 1-2%.  Gamma oryzanol is sometimes marketed as a “natural steroid” with the ability to increase circulating testosterone naturally. Gamma oryzanol is in fact not a single compound but a mixture of ferulic acid esters of triterpene alcohols and plant sterols. 

Gamma oryzanol has been used in both human and equine athletes in the belief that it elicits anabolic effects, ranging from increased testosterone production and release, to stimulating growth hormone release. …
