abstract: Alves, AR, Marta, C, Neiva, HP, Izquierdo, M, and Marques, MC. Does intrasession concurrent strength and aerobic training order influence training-induced explosive strength and V[Combining Dot Above]O2max in prepubescent children?. J Strength Cond Res 30(12): 3267-3277, 2016-The aim of this study was to analyze the interference of strength and aerobic training order over an 8-week period on explosive skills and maximal oxygen uptake (V[Combining Dot Above]O2max) in prepubescent children. One hundred twenty-eight prepubescent children aged 10-11 years (10.9 ± 0.5 years) were randomly selected and assigned to 1 of the 3 groups: intrasession concurrent aerobic before (GAS: n = 39) or after strength training (GSA: n = 45) or control group (GC: n = 44; no training program). The GC maintained their baseline level performance, and training-induced differences were found in the experimental groups. Increases were found in the 1-kg and 3-kg medicine ball throws: GAS: +3%, +5.5%, p ≤ 0.05, p < 0.001; GSA: +5.7%, +8.7%, p < 0.001, respectively; in the counter movement jump height and standing long jump length: GAS: +6.5%, +3.4%, p ≤ 0.05; GSA: +7%, +4.5%, p < 0.001, respectively; in the 20-m shuttle-run time: GAS: +2.3%; GSA: +4.6%, p < 0.001; and, in the V[Combining Dot Above]O2max: GAS: +7.3%, p < 0.001; GSA: +3.8%, p < 0.001 from pretraining to post-training. All programs were effective, but GSA produced better results than GAS for muscle strength variables, and GAS produced better results than GSA for aerobic capacity variables. The present study explored an unknown issue and added useful information to the literature in this area. These training methods should be taken into consideration to optimize explosive strength and cardiorespiratory fitness training in school-based programs and sports club programs.
