title: Acute effects of a single exercise session on serum lipids in untrained men.
abstract: Acute reductions in triglycerides and calculated low density lipoprotein cholesterol with little change in high density lipoprotein cholesterol have been reported in trained men after a single exercise session. To examine if a similar acute exercise effect occurs in sedentary subjects, wer measured triglycerides, total cholesterol, and high density lipoprotein cholesterol in eight sedentary men before and for 66 hours after a single 30-minute exercise session. The exercise was designed to simulate a typical exercise training session for untrained subjects. An isolated reduction in estimated low density lipoprotein cholesterol was observed 66 hours after the exercise. All other serum lipid measurements at 5 minutes and 1, 4, 18, 42, and 66 hours after exercise did not differ from pre-race concentrations. Consequently, the reductions in triglycerides and low density lipoprotein cholesterol and increase in high density lipoprotein cholesterol reported in previously sedentary subjects after exercise training are a chronic rather than an acute exercise effect.
