Abstract
Seventeen women and 30 men walked 15 mins. at 3.5 miles per hr. and ran for 5 mins. or until exhausted at 7 miles per hr. on a motor driven treadmill with a grade of 8.6%. Records of heart rate, blood pressure, ventilation, O2 consumption, R.Q., blood sugar, and blood lactate were obtained. Means and extremes for the data are compared for the 2 groups. The differences between the avgs. for the men and women are similar in nature to those between the trained and the untrained. As a group, the women were less fit than the men for both moderate and strenuous exertion. The 8 best women equalled in every respect the performance of the 10 poor men in the strenuous exhausting exercise, but showed slightly greater fatigue as a result of 15 mins. of non-exhausting exercise in which a steady state was reached and maintained.
