| Sumario: | Objectives: To meta-analyze lipid outcomes from supervised exercise interventions among healthy adults. Methods: Comprehensive search strategies identified trials testing supervised exercise interventions in samples of healthy adults. Data were coded and analyzed using random effects meta-analysis methods. Moderator analyses explored whether design, sample, or intervention characteristics were linked with lipid outcomes. Results: Data were analyzed from 344 comparisons. The overall mean effect size for 2-group comparisons was 0.28, corresponding to reduced total cholesterol of 8.65 mg/dl. Study effect sizes were greater where participants were obese at baseline, and for interventions utilizing low-intensity exercise. Conclusions: Supervised exercise interventions can improve lipid outcomes for healthy adults, with possible greater improvement for obese individuals, and through low-intensity exercise.
