A strength-balance training plan with three levels: beginner, intermediate, and expert. Individual motivation strategies: positive and negative reinforcement, goal setting, self-monitoring, awareness. Social motivation strategies: social comparison, monitoring of peers, emotional support, collaboration with peers to reach common in-game goals. Additional features: a virtual training plan community and communication features (i.e., private text messaging in the app, a bulletin board with links to newspapers, videos, and websites) Intervention group IG 1: Individual group that followed training using the individual version of ActiveLifestyle (=individual motivations strategies); IG 2: Social group that followed training using the social version of the ActiveLifestyle app (= the individual and social motivation strategies, the virtual training plan community and communication features) Control group Followed exercises with printed information without additional motivation strategy. Multi-component versus stand-alone app intervention Stand-alone | Outcome Physical activity (gait speed: preferred and fast walking speed) Other relevant outcomes None Measures Physical activity (gait speed by GAITRite walkway) | Physical activity Significant within-group increase in preferred gait speed across all groups at 12-week follow-up (p < .001). However, no significant between-group changes. Significant within-group and between-group increases in gait speed at 12-week follow-up. Participants walked significantly faster at post-test (1.72 m/s) than at pre-test (1.56 m/s; F =20.1, p < .001, ç =0.41). The main effect of group was also significant (F =5.3, p = .01 ç =0.27).
