n = 75 in model. HDL-c, high-density lipoprotein; HR, heart rate responses during a nongraded treadmill task (0.89 m·s−1); TC, total cholesterol; TR, triglycerides; V̇o2max, maximal oxygen uptake measured via indirect calorimetry during treadmill graded exercise test. *P value less than or equal to 0.05.
