Energy expenditure and enjoyment of small-sided soccer games in overweight boys

When space is limited, it would be preferable to play multiple small-sided soccer games (SSG) simultaneously on small courts, rather than a single game, to maximise participation. Given that the layouts of most gymnasiums incorporate several badminton courts, we examined whether energy expenditure and enjoyment of SSG on a badminton court (6.1 × 13.4 m) were comparable to larger court dimensions (volleyball and basketball courts; 9 × 18 m and 14.2 × 26.5 m, respectively). Twelve overweight boys played 30 min three-a-side SSG on each court in a counterbalanced design. During SSG, energy expenditure was estimated via accelerometry, heart rate was monitored and ratings of perceived exertion (RPE) and enjoyment were obtained. Energy expenditure was similar between badminton and volleyball courts, but lower than the basketball court (p < .05). Mean% HRmax was significantly lower on the badminton court than the volleyball and basketball courts (p < .05). There was no effect of court size on RPE or enjoyment (p > .05). These results suggest that it may be preferable to play SSG on a larger court when space is available. Alternatively, when space is limited the difference in energy expenditure between court sizes can be accounted for by an additional 2.3 min of play on a badminton court.
