Perceived exertion during deep water running and treadmill exercise was measured to examine gender and mode specific responses. Deep water running to VO2 peak was performed in 3-min. stages at leg speeds controlled by a metronome. Treadmill exercise was performed at matched leg speeds. VO2 and heart rate were continuously monitored by open circuit spirometry and radiotelemetry. Perceived exertion was measured using Borg's 6-20 point scale. Statistical analyses were performed using multiple linear regression with dummy coded discrete variables. Ratings of perceived exertion were significantly higher during deep water running when exercising at equal leg speeds. Mean rated perceived exertion at each stage of the test for either exercise mode was not significantly different between men and women.
测量了深水跑步和跑步机运动过程中的主观用力程度，以研究性别和运动方式的特定反应。以3分钟为阶段进行深水跑步至最大摄氧量（VO2）峰值，腿部速度由节拍器控制。跑步机运动以匹配的腿部速度进行。通过开路肺量计和无线电遥测技术持续监测VO2和心率。使用Borg的6 - 20分制量表测量主观用力程度。采用带有虚拟编码离散变量的多元线性回归进行统计分析。在相同腿部速度下运动时，深水跑步过程中的主观用力程度评分显著更高。两种运动方式在测试各阶段的平均主观用力程度评分在男性和女性之间无显著差异。
