Objectives
Narrative objectives1
The purpose of this study is to comprehensively examine the effects of hydrogen gas inhalation on post-exercise muscle damage markers, exercise performance, metabolic and respiratory responses, subjective fatigue, skeletal muscle impedance, muscle strength, and volatile organic compounds in exhaled gas during jumping exercises, which are explosive, high-intensity repetitive movements.
