Science progresses through healthy debates and challenging viewpoints. In this vain, we welcome critical evaluation of our work. Unfortunately, the commentary [1] on our documentation of our successful effort to disseminate Fun 5-a physical activity and nutrition program for children [2]-is, we feel, misplaced and missing the larger issues at hand.Critically re-evaluating our physical activity (PA) evidence supporting successful dissemination of the Fun 5 program, which used Sports, Play and Active Recreation for Kids (SPARK) AR as its main evidence-based PA component, we cannot agree with Beets and Huberty's conclusions. The pilot study revealed positive results in terms of lesson context, whereby intervention sites increased time devoted to play and decreased class management time compared to control sites [3]. This alone was a promising finding, and should not be ignored. This evidence demonstrates that after-school group leaders could rearrange their daily after-school schedules to incorporate significantly more PA-related time, without altering total after-school time. This unveiled the opportunity to increase children's PA during after-school via improved staff time management-an inexpensive, yet tailored intervention strategy. Admittedly, the first part of the pilot revealed no observed differences in children's PA time during the after-school program [3]. However, the self-report data revealed a significant increase in total daily strenuous leisure time PA [3], which included PA performed outside of the after-school program. This increase demonstrates treatment effect extending beyond the after-school setting and into everyday life of the children.The positive results regarding lesson context and children's total daily strenuous leisure time PA indicates program effectiveness and, more importantly, we learned of several areas of improvement. Of these improvements, the most significant observed was the maintenance of group leaders' support, enthusiasm, and motivation when delivering the SPARK AR component. Such observations informed dissemination planning, with all the stakeholders involved agreeing that dissemination was appropriate and worthwhile.The intervention was implemented in the delayed treatment control sites, resulting in a total of 13 elementary after-school programs [4] receiving the Fun 5 pilot intervention (grades 4-6, n=533; we thank the commentary authors for providing the opportunity to emphasize this point, which further strengthens the evidence described in our paper). Baseline observations across the 13 sites demonstrated that students were sedentary during the majority of time spent in the after-school program (87.1 % of after-school time was spent standing, sitting and lying down) [4]. Among all participating after-school sites, the Fun 5 intervention generated significant decreases in the time children were observed standing, sitting and lying (21 % decrease) and increased participating children's moderate-tovigorous physical activity (MVPA, 140 % increase) [4].
