All other outcomes were non-normally distributed and presented as median and IQR. Exploratory analysis was conducted on the association between friendship within teams and physical activity, using R version 3.3.2 (The R Foundation for Statistical Computing., 2016). The accelerometer data was processed using the ActiGraph software package version 1.0.1 [11]. Feasibility studies are not designed to investigate the effectiveness of interventions [29]. Thus, no significance testing was conducted
