The effects of active recovery using previously active and inactive muscle groups on power output and respiratory responses were examined. Ten male volunteers underwent two exhaustive 40-s bouts of leg cycling (1st Ex and 2nd Ex), separated by a 20-min recovery period. The recovery conditions were leg (Leg-Active) or arm (Arm-Active) cranking at 50% ventilatory threshold (VT), or sedentary control (Passive). The total output work (Total work) during the 2nd Ex in the Leg-Active condition was significantly higher than that in the Passive [299 vs. 282 J x kg body mass(-1) (J x BM(-1))]. The values of Total work, peak VO2 and peak heart rate during the 2nd Ex were significantly higher than those during the 1st Ex in both Leg- and Arm-Active. Total CO2 excess after the 1st Ex was significantly higher than that after the 2nd Ex (67.6 vs. 26.0 ml x BM(-1)) in Passive. After the 2nd Ex, the Total CO2 excess in the Leg-Active (51.5 ml x BM(-1)) was significantly higher than that in both the Passive (26.0) and Arm-Active (36.5), with Arm-Active being significantly higher than Passive. The recovery exercise using previously inactive muscles improved respiratory compensation ability related to performance enhancement.
研究了使用先前活跃和不活跃肌肉群进行主动恢复对功率输出和呼吸反应的影响。 十名男性志愿者经历了两次 40 秒的腿部循环衰竭（第 1 次衰竭和第 2 次衰竭），间隔 20 分钟的恢复期。 恢复条件为腿部（主动腿部）或手臂（主动手臂）以 50%通气阈值（VT）曲柄运动，或静止对照（被动）。 在主动腿部条件下，第 2 次衰竭期间的总输出功（总功）明显高于被动条件[299 比 282 J x 体重（kg）（J x BM（-1））]。 在主动腿部和手臂条件下，第 2 次衰竭期间的总功，峰值 VO2 和峰值心率的值均明显高于第 1 次衰竭。 在被动中，第 1 次衰竭后的总二氧化碳过剩明显高于第 2 次衰竭后（67.6 比 26.0 ml x BM（-1））。 在第 2 次衰竭后，主动腿部（51.5 ml x BM（-1））的总二氧化碳过剩明显高于被动（26.0）和主动手臂（36.5），主动手臂明显高于被动。 使用先前不活跃的肌肉进行的恢复运动提高了与性能增强相关的呼吸补偿能力。
