Efeitos dos vetores vertical e horizontal ao treinamento combinado em atletas profissionais de futebol em pré temporada

Abstract

The aim of this study was to compare the effects of three weeks of combined vertical and horizontal vector training in professional soccer players during the pre-season phase. A longitudinal design was employed to evaluate the efficacy of vertical and horizontal training programs, which consisted of eight neuromuscular training sessions distributed over three weeks (conducted on separate days, three times per week, except for the first week). Participants were matched based on their countermovement jump (CMJ) test results and subsequently randomized into two distinct groups (Horizontal Group and Vertical Group). The efficacy of the intervention was assessed through laboratory tests (including CMJ, horizontal jump, maximum power output in squat jump, and pelvic bridge) and field tests (speed over 5, 10, and 20 meters, Zigzag test, and 505 test for change-of-direction ability). After the intervention, the tests were repeated 48 hours after the final training session. The results showed that the Horizontal Group outperformed in CMJ, horizontal jump (HJ), and maximum power in pelvic bridge (MPP EP) (effect size: small), while the Vertical Group outperformed in 5- and 10-meter speed and the 505 test (effect size: small). After three weeks of intervention during the pre-season, it was concluded that both groups produced satisfactory results in professional soccer players. The Horizontal Group was more effective in developing laboratory variables (CMJ, HJ e MPP EP), while the Vertical Group was more effective in field variables (Vel 5 e 10m e Teste do 505.
