to investigate the effects of mild walk habit on the elderly men, the physiological variables such as cardiorespiratory function, body composition, and serum lipoproteins were compared among 3 groups. The subjects were habitually exercise
group(EG,
n=13), walking group(WG, n=10), and control group(CG, n=12). EG are tennis player, jogger, and climber. WG walked habitually 1 hour every day over 5 years. The subjects walking briskly for an average of 300 min/week over the year. WG demonstrated
higher
cardiorespiratory function(VO2max) (all, p<0.05) than CG. Maximul oxygen uptake and ventilatatory threshold are lower (p<0.05), are lower than EG, but not significant. Other evidence of better cardiorespiratory function was obtained from an
increase in
the distance covered in a 12 minute fast walk. howerver, there were nonsignificant differences between WG and CG in other physical fitness elements. For the habitually walking groups TG was lower than CG(p<0.05). Also, HDLC and HDLC/TC were lower
than
CG but not significant(p>0.05). These results suggest that the modest, flexible and unsupervised mild walk proved a sufficient stimulus to elicit improvements in aerobic capacity. And that briskly walking habit may results in the benificial
effect
on
the blood lipids in the elderly.
