Effect of a game-based high intensity interval training program on body composition in primary education: Comparison of the sport education model and traditional methodology

Abstract

The main aim of this study was to evaluate the effects on schoolchildren’s body composition of a game-based high intensity interval training (GB-HIIT) programme delivered during physical education. The secondary aim was to compare the effect of the implemented programme using two different methodologies: TheSport Education model and traditional methodology (TM). The study had a pre-post quasi-experimental design, and used a sample comprising 154 students aged between nine and 13 years (10.66±.82 years) enrolled in 5th and 6th grades of primary education. The programme lasted 15 sessions. Measurements of waist circumference and body fat percentagethrough bioelectrical impedance were taken. The results showed significant differences between the experimental group and control (p>.001) in waist circumference and body fat percentage. In conclusion, GBHIIT appears to be effective in countering effects on schoolchildren’s body composition.
