title: The Effect of Exercise Training on Serum Lipids in the Elderly.
abstract: Numerous intervention trials in young subjects suggest that aerobic exercise training exerts favorable effects on specific lipid subfractions, in particular serum triglycerides and high density lipoprotein (HDL) cholesterol. Cross sectional studies in older individuals suggest that active individuals have more favorable lipid profiles than inactive individuals. However, it remains controversial as to whether leisure time activity or fitness levels per se are independent predictors of lipid measures in the elderly versus their intermediate effects on body composition and body fat distribution. That is, a greater deposition of abdominal fat in the least fit individuals is associated with adverse lipid profiles. Short-term (8-weeks) aerobic exercise in elders is not associated with any significant changes in lipid profiles, however, longer term programs, particularly if associated with improvements in body fat distribution and/or weight loss, have been demonstrated to yield significant improvements in lipid subfractions, in particular triglycerides and HDL cholesterol.
