Purpose : The purpose of this study was to examine the effects of resistance training (RT) in physical education lessons on athletic motor skill competencies in secondary school children. Method : Seventy-eight males were randomized into experimental year groups or a control group. Experimental groups participated in RT during physical education lessons for a 6-week half-term. The control group continued with their games-based curriculum. Countermovement jump (CMJ) height, seated medicine ball throw (SMBT) distance, and RT skills battery scores were measured preintervention and postintervention. Results : All experimental groups significantly improved SMBT distance and RT skills quotient ( P &lt; .05). All intervention year groups also significantly improved CMJ height ( P &lt; .05), except for year 9. Although the control group did not show improvements in CMJ height and RT skills quotient, there was a significant improvement in SMBT distance ( P &lt; .05). The year 7 and 8 males exhibited greater improvements in CMJ height and SMBT distance ( d = 0.21–0.79) than in year 9 ( d = 0.00–0.40). Conclusion : Results of the study indicated that a 6-week half-term RT intervention in physical education lessons can improve athletic motor skill competencies ( P &lt; .05, d = 0.21–2.51) in male youths.
