Overreaching Attenuates Training-induced Improvements in Muscle Oxidative Capacity

ABSTRACTIntroductionThe aim of this study was to determine if muscle oxidative capacity is influenced by alterations in training volume in middle-distance runners.MethodsTwenty-four highly-trained middle-distance runners (n=16 male; VO2peak=73.3(4.3) ml·kg·min-1; n=8 female, VO2peak=63.2(3.4) ml·kg·
