This study determined the effects of low energy availability during three days of endurance training on muscle glycogen contents, exercise performance and blood parameters among male endurance runners. Energy availability is indicated as energy balance within the body. As results, endurance training under low energy availability reduced muscle glycogen contents and suppressed blood anabolic hormones concentrations (testosterone and insulin like growth factor-1). However, endurance performance was not attenuated. Present study is a first report which examined the time-course changes in muscle glycogen contents during endurance training under low energy availability and contributes to provide novel findings for the sports nutrition area.
