The purpose of this study was to examine the independent and combined effects of niacin and a single bout of exercise on the blood lipid and lipoprotein profiles in sedentary, postmenopausal women.

The study examined caffeine (5 mg/kg body weight) vs. placebo during anaerobic exercise. Eighteen male athletes (24.1 ± 5.8 yr; BMI 26.4 ± 2.2 kg/m²) completed a leg press, chest press, and Wingate test.
