The aim of the study was to examine submaximal and maximal physiological responses and perceived exertion during deep-water running with a vest compared with the responses during treadmill running in healthy elderly women. Eleven healthy women 70 +/- 2 years old participated. On two different occasions they performed a graded maximal exercise test on a treadmill on land and a graded maximal exercise test in water wearing a vest. At maximal work the oxygen uptake was 29% lower (p < .05), the heart rate was 8% lower (p < .05), and the ventilation was 16% lower (p < .05) during deep-water running than during treadmill running. During submaximal absolute work the heart rate was higher during deep-water running than during treadmill running for the elderly women. The participants had lower maximal oxygen uptake, heart rate, ventilation, respiratory-exchange ratio, and rate of perceived exertion during maximal deep-water running with a vest than during maximal treadmill running. These responses were, however, higher during submaximal deep-water running than during treadmill running.
本研究的目的是，在健康老年女性中，比较穿着背心在深水中跑步与在跑步机上跑步时的次最大和最大生理反应以及主观用力感觉。11名70±2岁的健康女性参与了研究。她们在两个不同场合分别在陆地上的跑步机上进行了分级最大运动测试，以及穿着背心在水中进行了分级最大运动测试。在最大运动强度时，深水中跑步时的摄氧量比跑步机跑步时低29%（p <.05），心率低8%（p <.05），通气量低16%（p <.05）。在次最大绝对运动强度时，老年女性深水中跑步时的心率高于跑步机跑步时。与最大跑步机跑步相比，参与者穿着背心在最大深水中跑步时的最大摄氧量、心率、通气量、呼吸交换率和主观用力感觉率更低。然而，在次最大深水中跑步时，这些反应比跑步机跑步时更高。
