Aim: This study aimed to examine the relationship between group exercise and exercise adherence among older community-dwelling individuals who attended a community sports club and to discuss the exercise programs that promoted exercise habits.
Methods: A total of 227 participants (117 women and 110 men), aged ≥ 65 years, who participated in the exercise programs (Wellness Age Club), provided by Resol no Mori, for at least 6 months from June 2017 to March 2019, were included in the analysis. Results obtained from the semi-annual questionnaire surveys, physical fitness tests, and annual medical check-ups were used, along with data on individual participation in programs and dates of participation. "Exercise adherence" was defined as participation in exercise programs for an average of ≥ 2 days per week for at least 24 weeks. "Group program participation" was defined as participation in group programs for an average of one or more times per week. The relationship between group program participation and exercise program adherence was analyzed using Poisson regression analysis.
Results: Group program participants were more likely to continue attending exercise programs in comparison to non-participants (Prevalence ratio=3.63 [95% CI: 1.98-6.65], p< 0.01). There was also a significant positive association between group program participation and exercise adherence among women (8.08 [1.94-33.56], p< 0.01) and men (2.84 [1.39-5.78], p< 0.01).
Conclusions: Our results suggest that group exercise programs increased social interaction among participants and promoted exercise adherence. Encouraging older people to attend group exercise may increase the number of older people who regularly exercise.
