Abstract/OtherAbstract:
This study aimed to compare the effects of distinct temporal organizations of strength and power training loads on strength, power, and speed improvements. Sixty soldiers with at least one year in the army volunteered for this study. The subjects were divided into four groups: control group (CG: n = 15; 20.18 ± 0.72 yrs; 1.74 ± 0.06 m; and 66.7 ± 9.8 kg); successive-mesocycle group (SMG: n = 15; 20.11 ± 0.7 yrs; 1.72 ± 0.045 m; and 63.1 ± 3.6 kg); successive-week group (SWG: n = 15; 20.36 ± 0.64 yrs; 1.71 ± 0.05 m; and 66.1 ± 8.0 kg); and simultaneous daily group (SDG: n = 15; 20.27 ± 0.75 yrs; 1.71 ± 0.068 m; and 64.0 ± 8.8 kg). In the SMG, heavy resistance training (HRT), jump squat exercise (JS), and counter movement jumps (CMJ) were performed in successive mesocycles of three weeks each. In the SWG, HRT, JS, and CMJ were trained in one-week blocks into three mesocycles of three weeks each. In the SDG, HRT, JS, and CMJ were trained daily in all of the three mesocycles of three weeks each. Total volume was equalized between groups. The following dependent variables were analyzed: squat 1 RM, CMJ height, 20-m sprint speed, mean power (MP) and mean propulsive power (MPP) in the squat exercise (60% of the squat 1 R M) and in the JS (45% of the squat 1 RM). Significant improvements for all of the dependent variables were detected from pre- to post-training in all of the training groups (p≤0.05), without any between-group differences. Our data suggest that the temporal organization of the training load is not critical for performance improvements in this population.
