PULSE REACTION TO PERFORMING STEP-UP EXERCISE ON BENCHES OF DIFFERENT HEIGHTS

Abstract
In 72 normal subjects, following the step up exercise, for periods of 30 or 60 sec., on benches 12-20 in. in height, the pulse rates taken for 30 sec. beginning 1 min. after exercise are practically the same for the various heights of the benches and the durations of exercise. The pulse rate for the 30 sec. immediately following the stepping up exercise depends upon the height of the bench and the duration of the exercise. After 30 sec. of exercise, the avg. increment is 3.7 beats/min. greater for each additional 2 in. increase in the height of the bench. After 60 sec. of exercise, the increment becomes 5.6 beats/min. greater for each additional 2 in. increase. The height of the bench and the duration of the step up exercise as used in this study do not significantly alter the pulse rate if the pulse record is taken 1 min. after exercise.
