TT—serum total testosterone level; FT—serum free testosterone level; C—serum cortisol level; total testosterone/cortisol ratio (TT/C); free testosterone/cortisol ratio (FT/C). E1—playing six 30 s one-on-one (1 × 1) games with a 2 min rest period; E2—playing six 45 s 1 × 1 games with a 3 min rest period. ^a significantly greater TT than 30 min post-exercise. ^b significantly greater TT/C, FT/C than 15 min post-exercise, 30 min post-exercise. ^c significantly greater TT than 15 min post-exercise and 30 min post-exercise. ^d significantly greater FT than 30 min post-exercise. ^e significantly greater cortisol than at rest. ^f significantly greater cortisol than 30 min post-exercise. * significantly greater than immediately post-exercise and at rest. ** significantly greater than at rest.
