Physical activity, Physical fitness, and mortality
Aerobic Center Longitudinal Study
Blair et al., 1989
Maximal treadmill exercise test in n=10,224 men and 3,120 women
oTest: time till exhaustion on treadmill test
Average follow up period of 8 years
oDeaths: 240 men and 43 women
Participants classified into quintiles
o1: shortest treadmill times (lowest fitness)
o5: longest treadmill times (highest fitness)
Physical Fitness and Mortality
Physical fitness can be measured more objectively than self-report of physical activity.
Most studies of PF and mortality risk have used treadmill tests to give an indication of physical
fitness.
oSome studies have used recovery heart rate (Cole et al., 1999) and exercise capacity in
METs (Mora et al., 2003)
Almost all studies in this area have defined fitness in aerobic terms (using surrogate markers for
VO2 max).

Document Summary
Maximal treadmill exercise test in n=10,224 men and 3,120 women: test: time till exhaustion on treadmill test. Average follow up period of 8 years: deaths: 240 men and 43 women. Participants classified into quintiles: 1: shortest treadmill times (lowest fitness, 5: longest treadmill times (highest fitness) Physical fitness can be measured more objectively than self-report of physical activity. Most studies of pf and mortality risk have used treadmill tests to give an indication of physical fitness: some studies have used recovery heart rate (cole et al. , 1999) and exercise capacity in. Almost all studies in this area have defined fitness in aerobic terms (using surrogate markers for. Evidence for dose response between fitness and mortality risk; There is the problem of genetic influence on fitness. The factor that has the big influence within large populations is uncertain. Physical fitness vs. other risk factors: acls and other studies. Confirmed the association of lower levels of physical fitness and all-cause mortality risk.
