Figure 5: The relative changes in exercise performances from baseline values of eight healthy males. Note: (A) Height of countermovement jump; (B) MVIC of knee extensors; (C, D) mean and peak power output in 10-second sprint cycling; (E, F) mean and peak power output in 30-second sprint cycling. Values are expressed as mean ± standard error. *P < 0.05 (paired t-test). HG: Molecular hydrogen-rich gas mixture; MVIC: maximum voluntary isometric contraction; n.s.: not significant; Placebo: normal gas.
