To investigate the effects of exercise habit of aged men on the aerobic exercise capacity, VO₂max and HR during exercise of three groups of aged men (runners, members of calisthenic club, gate ball players) were measured. VO₂max of runners and members of calisthenic club is higher than that of gate ball players, but there is no significant difference between runners and members of calisthenic clubs. Runners run 4 times/w 25 km/w and mean HR during running was 135±14. Members of calisthenic club exercise 1 time/w 2 hrs and mean HR during 10 minutes running and other exercise was 135±12, 99±10 respectively. Gate ball players practice gate ball 5 times/w, 15 hrs/w and mean HR during exercise was 98±14. It might be concluded that for the aged men, physical exercise of low frequency and short duration is enough to maintain their aerobic work capacity in beneficial condition if the intensity is enough.
