JAMA. 1926;86(19):1420-1422. doi:10.1001/jama.1926.02670450012004
Abstract

Since the summer of 1922 one of us (P. M. D.) has periodically been in charge of the inmates of a girls' camp among the Rocky Mountains. The high altitude of the camp (9,000 feet) and the naturally strenuous nature of the most important local activity (mountaineering) rendered desirable some reliable or at least suggestive test of cardiovascular efficiency. Routine examinations and grading by the method devised by E. C. Schneider1 were therefore instituted and proved to be very helpful. There was, however, no body of observations that could serve as a guide and establish the limits of normality for the Schneider grades in girls. Consequently, three of us (M. K. D., D. M. and M. M.) undertook to supply this demand and the results of our observations are the basis of this article.

The cases studied by us are not very numerous (200), but we believe that our
