Key result
Exercise training fails to improve cardiorespiratory fitness in overweight/obese postmenopausal women versus normal-weight peers.
Why the study?
The differences in exercise-induced improvements in cardiorespiratory fitness and heart rate response between normal-weight and overweight/obese postmenopausal women were unclear.
Does a 12-month exercise program improve cardiorespiratory fitness and heart rate response differently in normal-weight versus overweight/obese postmenopausal women?
Observational (n=155)
Does a 12-month exercise program improve cardiorespiratory fitness and heart rate response differently in normal-weight versus overweight/obese postmenopausal women?
Exercise-induced improvements in cardiorespiratory fitness and heart rate recovery are blunted in overweight/obese postmenopausal women compared to normal-weight women.

May inform BMI-tailored exercise programs for postmenopausal women; leaves open need for randomized confirmation of differential responses.
Ciolac et al. (2011) conducted an observational in Sedentary postmenopausal women (n=155). Overweight/obesity (BMI >25 kg/m2) vs. Normal-weight (BMI <25 kg/m2) was evaluated on Exercise-induced improvements in muscle strength, cardiorespiratory fitness and heart rate response. Overweight/obese postmenopausal women undergoing a 12-month exercise program failed to improve cardiorespiratory fitness and recovery heart rate, whereas normal-weight women improved by 6.6% and 5 bpm.
