Concurrent Training in Prepubescent Children: The Effects of 8 Weeks of Strength and Aerobic Training on Explosive Strength and V̇o 2max

Abstract

Alves, AR, Marta, CC, Neiva, HP, Izquierdo, M, and Marques, MC. Concurrent training in prepubescent children: the effects of 8 weeks of strength and aerobic training on explosive strength and V[Combining Dot Above]O2max. J Strength Cond Res 30(7): 2019-2032, 2016-The purpose of this study was to compare the effects of 8-week training periods of strength training alone (GS), combined strength and aerobic training in the same session (GCOM1), or in 2 different sessions (GCOM2) on explosive strength and maximal oxygen uptake (V[Combining Dot Above]O2max) in prepubescent children. Of note, 168 healthy children, aged 10-11 years (10.9 ± 0.5), were randomly selected and assigned to 3 training groups to train twice a week for 8 weeks: GS (n = 41), GCOM1 (n = 45), GCOM2 (n = 38) groups, and a control group (GC) (n = 44; no training program). The GC maintained the baseline level, and trained-induced differences were found in the experimental groups. Differences were observed in the 1 and 3-kg medicine ball throws (GS: +5.8 and +8.1%, respectively; GCOM1: +5.7 and +8.7%, respectively; GCOM2: +6.2 and +8%, respectively, p < 0.001) and in the countermovement jump height and in the standing long jump length (GS: +5.1 and +5.2%, respectively; GCOM1: +4.2 and +7%, respectively; GCOM2: +10.2 and +6.4%, respectively, p < 0.001). In addition, the training period induced gains in the 20-m time (GS: +2.1%; GCOM1: +2.1%; GCOM2: +2.3%, p < 0.001). It was shown that the experimental groups (GCOM1, GCOM2, and GS) increased V[Combining Dot Above]O2max, muscular strength, and explosive strength from pretraining to posttraining. The higher gains were observed for concurrent training when it was performed in different sessions. These results suggest that concurrent training in 2 different sessions seems to be an effective and useful method for training-induced explosive strength and V[Combining Dot Above]O2max in prepubescent children. This could be considered as an alternative way to optimize explosive strength training and cardiorespiratory fitness in school-based programs.

The role of age, sex, anthropometry, and body composition as determinants of physical fitness in nonobese children aged 6–12

“…The role of age in improving running speed is possibly associated with increasing stride length and frequency, and neuromuscular coordination. The seated chest pass test has been found to be a valid and reliable measure of upper body strength in kindergarten children (Davis et al, 2008) as well as a suitable strength-training tool for children about 11 years of age (Alves et al, 2016). This test uses a "general movement common to many sport skills" (Stockbrugger & Haennel, 2001).…”

Effects of order and sequence of resistance and endurance training on body fat in elementary school-aged girls

“…The resistance training programme comprising upper body (1 and 3 kg medicine ball throws) and lower body (jumps onto a box and hurdle jumps, from 0.3 to 0.5 m) plyometric exercises, as well as a speed drill (sets of 20 to 40 m speed runs). The subjects who performed the endurance training programme were subjected to a 20 m shuttle run exercise, readjusted after 4 weeks of training (for more details see [ 16 ]). Subjects performed two familiarization sessions before the training programme.…”
