In the training mode subgroup, five studies using running as the training mode demonstrated a near-significant reduction in total cholesterol (SMD = −0.30, 95% CI [−0.61, 0.02], p = 0.06), while two studies employing cycling interventions reported a significant decrease with a large effect size (SMD = −0.99, 95% CI [−1.58, −0.39], p < 0.01).
