Physical activity (PA) recommendations suggest students reach 50% moderate-vigorous physical activity (MVPA). However, studies show that many physical educators fail to meet this recommendation with their students. Researchers have argued that teachers' utilization of game-centered approaches (GCAs) such as the Tactical Games Model (TGM) may help students meet these recommendations because the game-skill-game lesson structure increases the time spent in game play. However, there are no published reports of whether students are meeting recommendations of 50% MVPA during these different learning tasks/activities (i.e., game and skill practice). Consequently, this study investigated whether students could accrue MVPA recommendations in three lesson contexts, which mirrored the game-skill-game format of the TGM: a) game play portion 1, b) skill practice, and, c) game play portion 2. Participants were 78 seventh and 96 fourth/fifth grade co-educational physical education (PE) students from two different schools. Two teachers taught 24 (middle) and 30 (elementary) level one TGM basketball lessons. Students wore Actigraph GT3X® triaxial accelerometers. Data were analyzed using two repeated measures ANOVAs. Neither the middle or elementary school students met national PA recommendations in any of the three lesson contexts. However, both middle and elementary school students had significantly higher MVPA during game-based activities. Middle school students accrued their highest levels of MVPA in the second game-play portion, whereas the elementary students accrued their highest levels of MVPA in the first game play lesson portion. These results suggest that in game-based physical education lessons, teachers should spend a greater portion of time in game play if their aim is to encourage student PA.
