Values are represented as means ± SD (upper/lower).

^1,2,3The 95% confidential interval did not contain the parameter value specified in the null hypothesis between the Sed, Hyp, or Tr groups, respectively.

^4,5,6Effects of exercise (E), hyperbaric exposure (H), and their interaction (I) were significantly different at P < 0.05, P < 0.01, and P < 0.001, respectively, using a two‐way ANOVA.

^7,8,9Significantly different from the Sed, Hyp, and Tr groups, respectively, at P < 0.05 using the Tukey‐Kramer multiple comparisons test.
