Examining the Feasibility of Smartphone Game Applications for Physical Activity Promotion in Middle School Students

Abstract Objective: The objective of this study was to determine the feasibility (i.e., limited efficacy testing, practicality, and acceptability) of a 6-week smartphone game-based applications program for promoting physical activity (PA) in adolescents in an afterschool program. Materials and Methods: This mixed-method, quasi-experimental design study included 27 adolescents who evaluated four smartphone PA game-based applications in two Boys & Girls Clubs of America. After an initial baseline week (i.e., usual activity during their visit to the Club), adolescents played each game for 1 week. During a final week, the participants could choose to play any combination of the four games. An established conceptual framework was used to assess feasibility. Efficacy was assessed by changes in PA via wrist-worn accelerometers (model GT3x+; ActiGraph LLC, Pensacola, FL). Practicality was measured through field notes, the number of players attending each session, and the proportion of attendees who played the gam...
