研究了系绳游泳时运动强度与摄氧量（VO2）、心率（HR）和血乳酸浓度（HLa）的关系。7名男性和10名女性受试者在5个次最大强度下游泳。用类别量表（RPE）和类别-比率量表（CR-10）测量感知劳累程度。5个因变量（VO2、HR、HLa、RPE和CR-10）均用方程R = a+c (S-b)n描述，以系绳游泳阻力(D)为自变量。男性和女性的D与VO2、HR和RPE均呈线性相关（r = 0.989 ~ 0.999）。男性HLa指数为3.2 (r = 1.000)，女性为3.6 (r = 0.991)，男性CR-10指数为1.5 (r = 0.998)，女性CR-10指数为1.9 （r = 1.000）。雄性和雌性的生长功能非常相似。结论：RPE作为运动强度的衡量指标是有效的，可用于实际游泳运动处方。
The relationships between perceived exertion and the physiological variables oxygen uptake (VO2), heart rate (HR) and blood lactate concentration (HLa) were studied in tethered swimming. Seven male and ten female subjects swam at five submaximal intensities. The degree of perceived exertion was measured both on the category scale (RPE) and on the category-ratio scale (CR-10). All five dependent variables (VO2, HR, HLa, RPE and CR-10) were described by the equation R = a+c (S-b)n with the drag (D) in tethered swimming as an independent variable. The relationships between D and VO2, HR and RPE were linear with a level of fitness correlation (r = 0.989-0.999) for both males and females. The HLa exponents were 3.2 for males (r = 1.000) and 3.6 for females (r = 0.991), and CR-10 were 1.5 for males (r = 0.998) and 1.9 for females (r = 1.000), respectively. The growth functions for males and females were very similar. The conclusion is that RPE is effective as a measure of exercise intensity and can be used for exercise prescription in practical swimming.
