| Outline of Final Research Achievements |
We assessed the effects of 10-year continuation of interval walking training (IWT) in older people, suggesting that 20% of initial participants continued IWT over 10 years. In the control group (CNT), VO2peak linearly decreased with advanced aging and the decrease was ～20% in females and males after 10 years. On the other hand, in the 10-year IWT group, VO2peak increased by ～20% for the first 6 month of the IWT and maintained the level along with the following 10 years in females and males. It was 40 % higher in the10-year IWT than in the CNT.
We found that there are no significant differences in the profile of VO2peak between the DO and 10-year IWT group before dropout. VO2peak was significantly higher in the 10-year IWT than other groups. Also, VO2peak was significantly higher in the DO group than in the CNT group. IWT over 10 years protected against age-associated declines in physical fitness in older people. The effect was partially preserved even if they dropped out on the way.
