In postmenopausal women, those who experience larger increases in aerobic fitness from exercise tend to have less of a reduction in the expected weight loss from that exercise, even when the amount...
Mechanism
Synthesis from 1 study
When postmenopausal women get better at aerobic exercise, their muscles get better at using oxygen to make energy efficiently. This means their bodies don’t need to slow down other activities or burn fewer calories to save energy, so they keep losing weight as expected.
Most probable mechanism
When women get better at aerobic exercise, their muscles become better at using oxygen to make energy, so they don’t need to slow down their metabolism or burn fewer calories to save energy. This lets them keep losing weight as expected.
Increased mitochondrial density and oxidative capacity in skeletal muscle improve the efficiency of ATP production per unit of oxygen consumed.
Enhanced metabolic efficiency reduces the need for compensatory reductions in non-exercise energy expenditure, such as spontaneous physical activity or resting metabolic rate.
Lower energy compensation allows a greater proportion of exercise-induced energy expenditure to translate into negative energy balance, supporting greater gains in VO2peak without confounding weight loss suppression.
