Maximal and submaximal aerobic fitness in postmenopausal women: influence of hormone-replacement therapy


, : Maximal and submaximal aerobic fitness in postmenopausal women: influence of hormone-replacement therapy. Applied Physiology, Nutrition, and Metabolism 33(5): 922-928

The purpose of this study was to examine whether maximal and submaximal aerobic fitness parameters (peak oxygen consumption and ventilatory threshold, respectively) are affected by hormone-replacement therapy (HRT) in moderately active postmenopausal women. Forty healthy, active, postmenopausal women (21 taking HRT, mean age 62+or-5 years; 19 not taking HRT, mean age 62+or-7 years) met the peak oxygen consumption criteria during a cycle ergometer test (15 W ramp) and achieved volitional fatigue. Breath-by-breath measurement was used to determine peak oxygen consumption and to estimate ventilatory threshold. There were no differences in characteristics (age, body mass, height, body mass index, leisure-time physical activity) between the non-HRT and HRT groups, nor were there any differences in responses to maximal exercise, with an observed peak oxygen consumption (mL.kg-1.min-1) of 22.9+or-3.8 in the non-HRT group and 22.0+or-4.7 in the HRT group. There was also no difference in submaximal aerobic capacity, with ventilatory threshold values (mL.kg-1.min-1) of 16.7+or-3.4 in the non-HRT group and 15.6+or-3.2 in the HRT group. In a sample of healthy moderately active postmenopausal women, there was no difference in maximal or submaximal aerobic fitness parameters between the HRT and non-HRT groups.
