The effects of exercise training intensity on various cardiometabolic risk factors in obese women with the metabolic syndrome following 16 weeks of either no exercise training (Control, n = 7), light-intensity exercise training (LIET, n = 11), or high-intensity exercise training (HIET, n = 9).

Two-way, mixed-effects analysis of variance of covariance with repeated measures (ANCOVA) was employed to examine mean differences in pre-to posttraining values, with the baseline values serving as the covariate (see methods for details). For all analyses, linear contrasts of the means were constructed to test our a priori hypotheses. Fisher’s Restricted Least Significant Differences criterion was utilized to maintain the a priori type I error rate of 0.05.
