“…An age-related reduction in VO 2max has also been well documented in both cross-sectional and longitudinal studies of male and female endurance athletes undertaking high levels of endurance training into older age [11,32,40,42,48,53,56,57,71,72,78,106,108], suggesting that some decrease in VO 2max appears inevitable with aging, despite physical training into older age. However, the rates of decline in VO 2max have been reported to be reduced [54,55,78], similar [108], or greater [47,71] than age-matched sedentary individuals.…”
