Maximal fysisk kapacitet försämras med 7-14 % per årtionde hos båda könen

[King Grub]

Lower physical activity levels in old age are thought to contribute to the age-related decline in peak aerobic and anaerobic power. Master athletes maintain high levels of physical activity with advancing age and endurance or power training may influence the extent to which these physical functions decline with advancing age. To investigate, 37-90-year-old power (n=20, 45% female) and endurance (n=19, 58% female) master athletes were recruited. Maximal aerobic power was assessed when cycling two-legged (VO2 Peak2-leg ) and cycling one-legged (VO2 Peak1-leg ), while peak jumping (anaerobic) power was assessed by a countermovement jump. Men and women had a similar VO2 Peak2-leg (mL·kg-1 ·min-1 , p=0.138) and similar ratio of VO2 Peak1-leg to VO2 Peak2-leg (p=0.959) and similar ratio of peak aerobic to anaerobic power (p=0.261). The VO2 Peak2-leg (mL·kg-1 ·min-1 ) was 17% (p=0.022) and the peak rate of fat oxidation (FATmax) during steady-state cycling was 45% higher in endurance than power athletes (p=0.001). The anaerobic power was 33% higher in power than endurance athletes (p=0.022). The VO2 Peak1-leg :VO2 Peak2-leg ratio did not differ significantly between disciplines, but the aerobic to anaerobic power ratio was 40% higher in endurance than power athletes (p=0.002). Anaerobic power, VO2 Peak2-leg , VO2 Peak1-leg and power at FATmax decreased by around 7-14% per decade in male and female power and endurance athletes. The cross-sectional data from 37-90-year-old master athletes in the present study indicates that peak anaerobic and aerobic power decline by around 7-14% per decade and this does not differ between athletic disciplines or sexes.

Hur snabbt är månne förfallet för nån som inte tränar?

[King Grub]

Långsammare.

in contrast to the prevailing view, the rate of decline in maximal aerobic capacity with age is greater, not smaller, in endurance-trained vs. sedentary wome

J Appl Physiol (1985). 1997 Jul;83(1):160-5.

Den maximala nivån som försämras är ju mycket lägre hos en otränad. Hos någon som är vältränad finns det mycket mer som kan försämras. Om den tränade slutar träna som gammal däremot, då lär det gå fort utför.

[Slartibartfast]

Samma för styrka/muskler?

[King Grub]

Hos kvinnor sjunker den kapaciteten långsammare om man tränar, men inte hos män. Män blir sämre lika snabbt oavsett vad dom gör. Men den som är tränad har ju mer styrka att ta av och kommer alltid att ligga bättre till än den otränade, även om förfallet sker lika fort.

habitual PA in healthy elderly men, unlike elderly women, does not reduce the age-related deterioration in P-max
