Researchers have taken preliminary steps toward unravelling the roles of two important regulatory proteins produced by muscle cells during exercise in horses.
The Polish research focused on 20 purebred Arabian horses, half of whom were in racehorse training and the remainder being conditioned for Endurance contests.
Sylwester Kowalik and his colleagues from the University of Life Sciences said skeletal muscle is considered the largest endocrine organ determining the maintenance of energy balance.
Adaptive changes in skeletal muscles in response to exercise affect the production, as well as the secretion, of proteins known as myokines, which play a crucial role in energy expenditure.
Kowalik and his colleagues carried out a preliminary study to investigate the impact of two different types of exercise on the circulating level of two myokines, myostatin and irisin, in horses...
