Maximal oxygen uptake and blood lipids.

One thousand and sixty males and 119 females age 10-69, were tested on the treadmill as they walked at 3 mph (2 mph in subjects 60 yr and older). Every 3 min, the grade was increased 3%. Oxygen uptake and related measurements were recorded during the 3rd min .at each grade. Subjects, age 10-39, exercised to. exhaustion and maximal oxygen uptake (VOz max) was measured. In subjects age m9, VOz max was estimated from sub-max VO1 and heart rate. Serum cholesterol and serum triglyceride were determined in most of these subjects. After removing the effects of age, wt and sum of four skinfolds, nonfasting values of cholesterol and triglyceride concentrations were unrelated to 90, max.
