In Part 1 of this study,1 we presented the results of our investigation of the maximum physical capacity of normal schoolchildren and of the effect of maximum physical effort on the circulatory reactions.
It is the consensus of opinion among investigators that, in normal persons, after moderate amounts of exercise, there is always an increase in the pulse rate and in the systolic blood pressure. However, the opinions vary regarding the effect of exhaustive exercise on the circulatory reactions, especially in the event of collapse. A review of the extensive literature on this subject leaves one confused and in doubt. The reasons for this are: 1. No one has ever established a normal quantitative standard of physical capacity for work. This applies to adults as well as to children. 2. The technic employed lacks uniformity. 3. No careful and comprehensive attempts have been made, either by the physiologist or
