BACKGROUND Few adults in the United States obtain sufficient physical activity (PA) despite knowledge of the associated health benefits. The current feasibility study examined the feasibility of a novel modified sports intervention designed to promote enjoyment and sustained PA in sedentary adults. METHODS The US adults (N = 22, mean age 39.2 y, male/female percentage 54.5/45.5) in Central Pennsylvania participated in the PlayFit sports program for 60-minute sessions, 2 to 3 times per week, over the course of 10 weeks and 24 game sessions; completing 198 person sessions collectively. Primary outcomes were PA (accelerometry) and intervention satisfaction. RESULTS Percentage of time in moderate to vigorous activity ranged from 35.0% (volleyball) to 91.2% (ultimate frisbee). Percentage of time spent in vigorous activity ranged from 0.0% (volleyball) to 29.5% (team handball). Satisfaction, based on a 10-point scale with 10 being the most satisfied, ranged from 7.7 (kickball) to 8.7 (floor hockey and soccer). On average, all sports were rated highly, with the majority rated >8.5 and one rated <8.0. Percentage of time spent in the moderate to vigorous range was lower in men than in women (73.2% vs 80.0%, P = .01), but did not differ by age or body mass index. CONCLUSIONS PlayFit is a promising first step in exploring the potential of modified sports programs to enhance population PA levels.
