Mr. Daichi Tanaka is Graduate Student in Faculty of Sport and Health Science of Ritsumeikan University, and his research manuscript was accepted and published in International Journal of Sports Medicine, which collaborated with Professor Tadao Isaka and Assistant Professor Tadashi Suga. Previous studies (e.g., Kido et al. Physiol Res, 2015) reported that ischemic preconditioning (IPC) enhances whole-body exercise endurance. However, it is poorly understood whether the beneficial effects originate from systemic (e. g., cardiovascular system) or peripheral (e. g., skeletal muscle) adaptations. The present study revealed that IPC can enhance muscular endurance during fatiguing isometric exercise. Moreover, IPC accelerated muscle deoxygenation dynamics during the exercise. Therefore, we suggest that the origin of beneficial effects of IPC on exercise performance may be the enhanced mitochondrial metabolism in skeletal muscle.
