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.
在受限游泳中研究了主观用力程度与生理变量摄氧量(VO2)、心率(HR)和血乳酸浓度(HLa)之间的关系。7名男性和10名女性受试者以五种亚最大强度游泳。主观用力程度通过类别量表(RPE)和类别比率量表(CR - 10)进行测量。所有五个因变量(VO2、HR、HLa、RPE和CR - 10)都用方程R = a + c(S - b)n来描述,其中受限游泳中的阻力(D)作为自变量。D与VO2、HR和RPE之间的关系呈线性,男性和女性的拟合度相关性水平(r = 0.989 - 0.999)。男性的HLa指数为3.2(r = 1.000),女性为3.6(r = 0.991),CR - 10男性为1.5(r = 0.998),女性为1.9(r = 1.000)。男性和女性的增长函数非常相似。结论是,RPE作为运动强度的一种测量方法是有效的,可用于实际游泳中的运动处方。
