The effect of menopausal status on substrate utilization in younger women during submaximal exercise
<p> PURPOSE: The purpose of this study was to determine if surgically-induced menopause in younger women affects substrate utilization during submaximal exercise while controlling for other potential confounds. METHODS: Thirteen untrained female subjects (33-50 years old) were recruited: oopho...

METHODS: Thirteen untrained female subjects (33-50 years old) were recruited: oophorectomized (Group O = 5) and premenopausal controls (Group C = 8).

RESULTS: When controlling for multiple variables affecting whole-body substrate utilization (age, VO<sub>2max</sub>, physical activity, body composition, fasting glucose, menstrual phase and diet), there was no difference in substrate utilization between pre- and postmenopausal women as measured by respiratory exchange ratio (RER) (0.83 ± 0.04 v 0.84 ± 0.03, <i>p</i>=0.47).
