Self-reported physical activity levels over two decades did not significantly alter echocardiographic measures of cardiac morphology or function in postmenopausal women (p>0.05).
Cross-Sectional (n=34)
Does moderate or high physical activity over two decades improve echocardiographic measures of cardiac structure and function in postmenopausal women compared to a sedentary lifestyle?
In postmenopausal women of similar body size, long-term differences in physical activity levels and VO2 max do not translate to differences in resting echocardiographic measures of cardiac structure or function.
p-value: p=>0.05
Abstract The risk of cardiovascular disease increases significantly after menopause. We sought to assess the impact of different activity levels on cardiac structure and function in postmenopausal women. We grouped age‐similar, postmenopausal women by self‐reported physical activity levels over two decades. The study involved 34 women (age 61 ± 1 years; 11 ± 2 postmenopausal years; body mass index 23 ± 3 kg/m 2 ) categorized into three activity tiers: sedentary (SED; ≤1 h exercise weekly; n = 9); moderately active (MOD; ≥2 ≤6 h low/moderate intensity exercise weekly; n = 11) and highly active (HIGH; >4 h of moderate/high intensity exercise weekly; n = 14). Maximum oxygen uptake (VO 2 max) differed significantly ( p 0.05) in height, Total fat‐free mass, body surface area or in echocardiographic measures of left ventricular (LV) morphology, systolic function, diastolic function and right ventricular function. Contrary to our hypothesis, these findings reveal that marked differences in activity level and VO 2 max are not reflected in measures of LV morphology or echocardiographic indicators of cardiac diastolic or systolic function in postmenopausal women of similar body size.
Fischer et al. (Thu,) conducted a cross-sectional in Postmenopausal state (n=34). Physical activity vs. Sedentary lifestyle was evaluated on Echocardiographic measures of left ventricular morphology, systolic function, diastolic function and right ventricular function (p=>0.05). Self-reported physical activity levels over two decades did not significantly alter echocardiographic measures of cardiac morphology or function in postmenopausal women (p>0.05).
