title: The impact of exercise training on blood lipids in older adults.
abstract: Increasing physical activity is often prescribed to improve blood lipids; however, the efficacy of exercise in improving blood lipids in older adults is not clear. The objective of this study was to examine the effects of different exercise modes on blood lipid levels in previously sedentary older adults engaging in a 16-week exercise intervention. One hundred thirty-one subjects (mean age 74.6+/-6 years) were randomly assigned to a resistance training group, aerobic walking group, combined exercise group, or nonexercising control group. Blood lipids were measured at baseline, 8 weeks, and postintervention. Exercise mode did not impact blood lipids. All groups had lower lipid levels over time. Total cholesterol, low- and high-density lipoprotein, and triglycerides were significantly lower. The decrease in all groups, including the controls, may be due to a seasonal effect in older adults that has been documented in younger individuals.
