Effects of contrast training; jump power in basketball players

Abstract

The objective of the research was to determine the effects of a contrast training plan on vertical jump power under a quantitative approach and quasi-experimental design; a sample of 31 players from the sports program of the municipality of San Martín de los Llanos; Two groups were formed, Experimental Group (EG n=15); Control Group (CG n=16). The 15 GE players performed 2 general strengths preparatory training mesocycles, 8 weeks each, 3 sessions of 1 hour, raising body temperature for 10 minutes and 50 minutes combining squat exercises with loads of 70% to 90%, maximum repetition (1RM), immediate. transfer to 3 jumps per set, lying strength, arches, forward strength and hurdles; The CG group trained only on the playing field without EG specifications. Before and after the execution of the plan, both groups on the court applied three Bosco test jumps: Countermovement Jump (CMJ), Squat Jump (SJ) and Abalakov (ABK) using the AXON JUMP contact platform, having significance in the results; The EG showed greater room for improvement, in the pretest they were below the performance indices of the CG and when executing the posttest, the results showed greater performance, surpassing the CG. In conclusion, the contrast training plan leads to a process of adaptation and applicability of the exercises that allows the power level to be increased safely, with positive effects on the player's motor and movement functional capacity.
