1 EFFECTS OF WALKING HABIT ON AEROBIC WORK CAPACITY AND VITAL AGE IN MIDDLE-AGED AND ELDERLY WALKERS NOBUO TAKESHIMA, KIYOJI TANAKA, FUMIO KOBAYASHI, TAKEMASA WATANABE and MASATOSHI NAKATA Abstract The purpose of this investigation was to determine the effects of daily walking on aerobic work capacity, vital age and other fitness components in middle-aged and elderly walkers. The subjects were thirty-six walkers (average 65.0 }8.0 yr, 51 `80 yr), whose training period averaged 13.5 } 9.0 yr. The walkers were significantly greater in maximal oxygen uptake ( O2max), and oxygen uptake at the lactate threshold ( O2LT), and were 6.5 yr younger in vital age (VA) than sedentary middle-aged and elderly. These findings suggest that middle-aged and elderly walkers have more favorable profile of aerobic work capacity and of health status when compared to sedentary persons. (Jpn. J. Phys.
