Abstract
Six males, ages 31-58, with ischemic vascular disease of the lower extremities, underwent treadmill testing with measurement of oxygen uptake at 45-60 seconds of exercise (VO2-45-60) as the test score. Tests were performed at 41, 123 and 164 watts of power against gravity. Depressed values were found in five subjects with aortic, iliac or common femoral disease but normal values in a subject with narrowing of the left superficial femoral artery. Reconstructive surgery resulted in normal values in four subjects retested. In three of these a calculation was made of the increased volume of oxygen uptake during the first minute of exercise associated with postsurgical improvement. The average was 430 ml, a value high enough to suggest increased aerobic metabolism of exercising muscles.
