THE HEART RATE OF BOYS DURING AND AFTER EXHAUSTING EXERCISE

Abstract

Slowing of the heart rate after exercise is so rapid that a true picture of the effect of exercise on the curve can be gained only by recording the rate continuously during exercise. Such a study, carried out with the cardiotachometer, on 27 boys subjected to exhausting exercise, showed an average maximum rate during exercise of 190. The highest recorded rate was 204. Although the major drop in rate is completed within 1 min. after exercise, in most cases, the rate is still considerably above the former resting level at the end of an hour.
