Aerobic training, but not creatine supplementation, alters the gluteus medius muscle

Published: 2005-08-29

Brief content of the article
The aim of this study was to investigate the effect of oral supplementation of creatine on the muscular responses to aerobic training. The authors submitted twelve Arabian purebred horses to aerobic training for 90 days, with and without creatine supplementation. Body weight (BW), body condition score (BCS) and muscle fibres from the gluteus medius were compared and evaluated. Physical conditioning was conducted on a high performance treadmill. The results demonstrated that the animals maintained a moderate BCS without alteration of BW during the course of the training, providing evidence of equilibrium between feed intake and caloric expenditure during the study period. The training resulted in changes in muscle fiber composition. The authors did not observe any beneficial effect from creatine on the skeletal characteristics examined.
