Muscle mass and insulin sensitivity in postmenopausal women after 6-month exercise training

Cohort Study

Human

Similar Assertions

In women who are postmenopausal, not very active, and carry extra weight, having more muscle doesn’t always mean better blood sugar control — sometimes those with bigger muscles actually have worse insulin resistance.
