Abstract
The purpose of this study was to investigate the validity of the postexercise heart rate (HR) as a means of estimating the HR during exercise. The subjects were 24 collegiate women who were not currently involved regular physical activity. HR was recorded during and following exercises performed at an intensity of 40, 50, 60, or 70% maximal oxygen uptake. The 4 methods of estimating exercise HR were done by measuring postexercise HR for: (1) 6 sec and multiplied by 10, (2) 10 sec and multiplied by 6, (3) 15 sec and multiplied by 4, and (4) 15 sec and multiplied by 4 and plus 10 (15+10-Method) . The results showed that the 15+10-Method estimated the exercise HR most accurately among these 4 methods.
