Acute decrease in serum triglycerides with exercise: Is there a threshold for an exercise effect?

摘要: Acute reductions in triglycerides and low density lipoprotein (LDL) cholesterol concentrations have been demonstrated endurance athletes after prolonged exercise. To determine if similar changes occur untrained subjects to the duration of exercise necessary for such changes, we measured serum lipids lipoproteins 10 sedentary men 1 hour at their anaerobic threshold. Findings were compared with those 9 competitive cyclists 2 hr LDL increased immediately hours Total high (HDL) also session. These increases transient not significant when corrected plasma volume. Serum unchanged 4 By 24 hr, however, had decreased both trained (17%) (22%) session (33% p less than 0.01) results demonstrate a delayed decrease triglyceride concentration that is related probably has no distinct The lower level training due least part an acute effect.
