Five horses were studied during a five-week regime of controlled intensive daily training on a high-speed treadmill followed by five weeeks of detraining. Muscle biopsies were taken weekly from both the right and left gluteus muscle and from the sternocephalicus muscle before, and at the end of, the training and detraining periods. Histochemical and biochemical analyses of the sternocephalicus muscle showed no metabolic adaptation with either training or detraining. No significant differences were observed in any of the analysed parameters in the gluteus muscle between contralateral sites. Glycogen levels decreased by 10 to 15 per cent after one two weeks of training, remained low during the training period and increased to petraining levels one week's cessation of training. Citrate synthase activity increased rapidly and was 27 per cent higher after one week and 42 cent higher after five weeks of training. Lactate dehydrogenase acrivity decreased by 15 per cent during this period. The changes seen in these enzyme levels persitent during the detraining period. No alteration were seen in fibre type composition but type IIA fibre areas decreased by 19 per cent after five weeks training and capillary density increased by 17 per cent. It is concluded that a period of intensive training will rapidly increase the oxidative capacity and the capillary density in an actively working muscle, and that these metabolic adapatations are well maintained during a subsequent period of detraining.
