The purpose of this study was to investigate through electronic monitoring whether immediate post-exercise heart rates determined in an erect position are an accurate representation of heart rates achieved during swimming exercises performed in the prone position. In addition, a comparison was made to determine what differences, if any, existed between immediate post-exercise heart rates determined by radial palpation and immediate recovery heart rates determined by electronic monitoring.

Fourteen male and four female members of the Eastern Illinois University Swim Program volunteered to be subjects.

Each of the subjects swam eight lengths of the pool (200 yds.) at approximately 60-70 percent of their heart rate reserve. Heart rates were recorded continuously by a Vantage Performance Monitor during exercise and recovery periods. Immediately following exercise the subjects stood erect, located a radial pulse as quickly as possible and counted their pulse for a 10-second period. Simultaneously, the Vantage Performance Monitor recorded heart rates during this ten second period.

An analysis of variance (ANOVA) with repeated measures on the same subjects and Newman-Keuls post-hoc comparisons revealed significant differences between the three different measurements; the electronically monitored exercise heart rates, the electronically monitored recovery heart rates and the palpated recovery heart rates.
