Key result
The age-associated decline in maximal oxygen uptake was twofold steeper in older men (-57 ± 5 ml/min/yr) compared to older women (-23 ± 2 ml/min/yr; P<0.0001), causing gender differences to dissipate.
Why the study?
Does gender influence the age-associated decline in maximal oxygen uptake and its physiological determinants in sedentary older adults?
Population
100 sedentary adults aged 60 to 92 years (71 women, 29 men) with no evidence of cardiovascular disease.
Comparison
Maximal treadmill exercise testing. vs Comparison between men and women across…

Should not yet change clinical assessment of aerobic capacity; leaves open need for longitudinal confirmation of sex-specific declines.

Does gender influence the age-associated decline in maximal oxygen uptake and its physiological determinants in sedentary older adults?
p-value: p=<0.0001
In older adults, maximal oxygen uptake and cardiac output decrease more rapidly with age in men than in women, causing gender differences in aerobic capacity to dissipate in later decades of life.
Weiss et al. (2006) conducted a cross-sectional in Sedentary older adults without cardiovascular disease (n=100). Gender was evaluated on Age-associated decline in maximal oxygen uptake (V(O2 max)) (p=<0.0001). The age-associated decline in maximal oxygen uptake was twofold steeper in older men (-57 ± 5 ml/min/yr) compared to older women (-23 ± 2 ml/min/yr; P<0.0001), causing gender differences to dissipate.
