Abstract

The effects of walking on muscle oxygen consumption in nonexercising forearm flexor muscles (nonexV·O 2mus ) during and after exercise were examined. Seven healthy male subjects performed treadmill walking for 30 min at 6 km/h. The nonexV·O 2mus values at rest, during exercise, and during recovery after exercise were measured by near infrared spectroscopy. NonexV·O 2mus was determined using the rate of decrease in oxygenated hemoglobin during arterial occlusion. The nonexV·O 2mus during exercise significantly increased by 1.2( (cid:2) 0.1)-fold and 1.3( (cid:2) 0.1)-fold over the value at rest at 20 and 30 min during exercise, respectively. NonexV·O 2mus returned to the value at rest after 1 min of recovery and then showed no significant change for 20 min after exercise. This study suggested that walking for 30 min induced an increase in nonexV·O 2mus and that the increase of nonexV·O 2mus was somewhat significant. In addition, the results suggested that increase nonexV·O 2mus during walking required a duration of over 20 min.
步行促进健康对非运动肌肉耗氧量的影响
研究了步行对运动期间和运动后非运动前臂屈肌(nonexV·O 2mus)肌肉耗氧量的影响。7名健康男性受试者以6公里/小时的速度在跑步机上行走30分钟。采用近红外光谱法测定静息、运动和运动后恢复时的nonexV·o2mus值。用动脉闭塞期间氧合血红蛋白的下降速率测定NonexV·o2µs。运动时nonexV·O 2mus比运动时休息时分别显著增加1.2((cid:2) 0.1)倍和1.3((cid:2) 0.1)倍。NonexV·o2mus在恢复1 min后恢复到静止值,运动后20 min无明显变化。本研究提示,步行30 min可诱导非exv·o2mus增加,且非exv·o2mus增加较为显著。此外,结果表明,步行时增加nonexV·O 2mus需要持续时间超过20分钟。
