Values are shown as means and standard deviation. BF, body fat percentage; EE, energy expenditure; EF, effect size as determined by Hedges’ g; HDL, high-density lipoprotein; HR, heart rate; LDL, low-density lipoprotein; V̇o2max, maximal oxygen uptake assessed during a graded exercise test; TC, total cholesterol; TG, triglycerides. ^Performed during nongraded walking on a treadmill at 0.89 m/s; †Sample size for 30 and 45 in participants < and > 50th percentile for body fat percentage, respectively. P values correspond with between-group comparison using an independent samples t test.
