Exercising Hungry Racehorses?

A new study in the European Journal of Applied Physiology has outlined the benefits of exercising at low glycogen levels with cyclists. The key finding was that exercising with low glycogen levels amplifies the expression of the major genetic marker for mitochondrial biogenesis which may be beneficial for improving muscle oxidative capacity. Could we see a similar adaption in thoroughbreds? Here is a link to the study and the abstract is below. Recent studies suggest that carbohydrate restriction can improve the training-induced adaptation of muscle oxidative capacity. However, the importance of low muscle glycogen on the molecular signaling of mitochondrial biogenesis remains unclear. Here,

A Population Study on Thoroughbreds

In recent months Brandon Velie, a PhD student at Sydney University has published three very interesting population studies on horses in Australia and Hong Kong in the Equine Veterinary Journal. Profiling the careers of Thoroughbred horses racing in Hong Kong between 2000 and 2010 The association of age at first start with career length in the Australian Thoroughbred racehorse population Profiling the careers of Thoroughbred horses racing in Australia between 2000 and 2010 Brandon's particular interest is durability of the breed on a population basis (tens of thousands of horses) and his studies have thrown up some interesting facts (my comments in brackets). Risk of retirement from racing de
