Exercise video games are associated with more positive affective response, which predicts physical activity adherence

Abstract

BackgroundA more positive affective valence during exercise is predictive of adherence to physical activity programs. This study examines the relationship between affective response during exercise and longer-term maintenance of physical activity among individuals using exercise video games (EVGs) and standard modalities of physical activity (i.e., walking, cycling). MethodsHealthy adults (mean age 45.4, SD = 14.5) were randomly assigned to a 12-week supervised, thrice weekly program of EVGs (n = 93) or Standard exercise (n = 96), and were assessed for affect immediately before, at the mid-point, and immediately after one exercise session per week. Participation in moderate-to-vigorous physical activity (MVPA) was conducted at end of treatment (EOT) and 6-month follow up. ResultsEVG participants reported more positive affective valence during exercise compared to Standard participants (b = 0.63, SE = 0.08, p < .001), and perceived less exertion (b = 0.52, SE = 0.36, p = .04) compared to Standard participants. For both groups, a more positive affective valence during exercise was significantly predictive of continued physical activity at 6-months (b = 6.64, SE = 2.50, p = .01). EVG participants also showed a significant chronic effect such that week-to-week there were improvements in affect prior to exercise and this effect was significantly associated with greater MPVA at EOT and follow-up (b = 21.96, SE = 10.10, p = .03 at EOT). Among Standard participants no significant chronic effect was seen over time. ConclusionsEVGs may provide an effective means of promoting more positive shifts in affective valence both during, and in anticipation of, physical activity that encourages longer-term participation.
