Purpose: Whether active or passive recovery after resistance exercise may affect anabolic and catabolic response is not clear. The aim of this study was to examine the effect of active (moderate or low intensity running) and passive (rest) recovery after resistance exercise on testosterone, cortisol and testosterone/cortisol ratio (T/C) responses. Methods: By counter-balanced design, nine recreationally active males (age: 23.89 ± 0.86 yrs of age; height: 172.89 ± 1.30 cm; weight: 68.37 ± 2.72 kg; VO2max: 56.56 ± 1.70 ml/kg/min) completed three tests including: 65% VO2max running (moderate intensity, RM), 40% VO2max running (low intensity, RL) and passive rest (RR) following 3sets of four resistance exercises (bench press, leg extension, front lat pulldown and leg curl, 12 repetitions at 60%1RM with 2min rest among all sets and exercises). In order to evaluate the systemic anabolic status, we measured plasma testosterone, cortisol and T/C ratio before resistance exercise (baseline), immediately after either active or passive recovery (post), and 30min after recovery (rest). Results: In RM group, T/C was significantly lower (decrease 18.5%, p<.05) than baseline at rest. In RL group, T/C was significantly higher (increase 79.1% at post and increase 123.2% at rest, p<.05) than baseline at post and rest, respectively. At rest, the T/C of RL was higher than RM (RM: 0.49 ± 0.12, RL: 1.08 ± 0.19, p<.05). Conclusions: Resistance exercise and low intensity aerobic exercise is more favorable to enhance anabolic response during post-exercise recovery.
