PART I. ‘THE PROBLEM EXAMINED or a decade preceding the outbreak of the present war there was EF a growing number of persons, claiming some prominence in the field of health, who received wide spread publicity through statements asserting that school and college athletics were so strenu- ous that participants were damaged physically.
