Key result

Regular vigorous exercise can slow the rate of decline in VO2max by as much as 50%, although the absolute age-associated decline is greater in men than women.

Why the study?

Does aerobic exercise training improve VO2max differently in older men and women?

Key Points

The aim is to examine how age-related declines in VO2max differ between genders and the impact of exercise.
Analysis of cross-sectional and longitudinal data on VO2max in older men and women.
Comparison of exercise levels and their association with aerobic power declines.
Evaluation of gender-specific physiological adaptations to exercise training.
Men experience a greater absolute decline in VO2max (L or mL/min) than women, but relative declines equalize per decade.
Regular vigorous exercise can slow VO2max decline by up to 50%, while stopping or reducing training accelerates the decline.
Strong correlation observed between declines in maximal heart rate and VO2max, with minimal impact from physical activity on heart rate.

Structured PICO

Does aerobic exercise training improve VO2max differently in older men and women?

Population

Men and women experiencing age-associated decline in cardiorespiratory fitness

Intervention

Aerobic exercise training and physical activity

Outcome

Age-associated decline in VO2maxsurrogate

Aerobic exercise improves fitness in both older men and women, but the physiological adaptations differ by gender.

Limitations

Selection bias in cross-sectional studies may report a slower rate of decline than longitudinal studies
Reduction or cessation of training with advancing age may result in a misleading acceleration in decline
Selection bias in cross-sectional studies
Misleading acceleration in decline due to reduction or cessation of training with advancing age in longitudinal studies

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

Supports sex-informed exercise counseling in older adults; leaves open optimal regimens for VO2max preservation.

Robert F. Zoeller (2008) conducted a review in Age-associated decline in cardiorespiratory fitness. Aerobic exercise training / Physical activity was evaluated on Age-associated decline in VO2max. Regular vigorous exercise can slow the rate of decline in VO2max by as much as 50%, although the absolute age-associated decline is greater in men than women.
