Abstract

This study evaluated force and velocity parameters of vertical jump performance in countermovement jump (CMJ) and squat jump (SJ) and compared results for sprint runners and volleyball players. Twenty-four male athletes (12 regional/national-level sprint runners and 12 national-level volleyball players) performed CMJ and SJ on a force platform. The following variables were analyzed: jump performance (jump height and power), peak velocity (PV), absolute and relative maximum force (MF), rate of force development (RFD,) and time to reach maximum force (TMF). In CMJ, jump height was correlated with PV (r=0.97) and normalized MF (r=0.47), whereas jump power was significantly correlated with all variables, except MF (r=0.12). In SJ, PV and normalized MF were significantly correlated with jump height (r=0.95 and r=0.51) and power (r=0.80 and r=0.87). In addition, TMF was inversely correlated with power (r=-0.49). Runners had higher performance variables (height and power), normalized MF and PV than volleyball players in both CMJ and SJ. Velocity and maximum force were the main determinants of height and power in the two types of vertical jumps. However, explosive force (RFD and TMF) was also important for power production in vertical jumps. Runners had a better vertical jump performance than volleyball players.

Comparison of Power, Velocity and Force Parameters during Loaded Squat Jump Exercise in the Handball and Arm Wrestling Players

“…However, in some studies, it was compared the kinetic and kinematic parameters during jump exercises of athletes who competed in different sports. Dal-Pupo et al, (2012) compared force and velocity values during SJ and countermovement jump in the both sprint runners and volleyball players. In mentioned study, it was reported that sprint runners had greater values in terms of PV in both countermovement jump and SJ than volleyball players.…”

“…Strength and velocity parameters determining power may have varied characteristics according to the movement practiced in sport branches (Dal-Pupo, Detanico & Dos-Santos, 2012). Determining these parameters can be useful while determining specific training characters in sports where explosive but various movements required.…”

“…The power rating can be characterized as the rate of work realization. This is shown as units of time, more specifically, the power produced by speech (Dal Pupo, Detanico, & Santos, 2012).…”

“…Performance in vertical jumps is considered one of the most efficient indicators of the level of muscle power, which is produced by the lower limbs muscles (Dal Pupo, Detanico, & Santos, 2012). An important variable that relates to power is the elastic energy stored in the elastic structures of the agonist muscles during the jumping impulse phase, which is based on the stretching-shortening cycle (CAE) (Komi, 2000).…”

Influência do Aquecimento no Desempenho do Teste de Salto Horizontal em Jovens Adultos

“…O teste de SH se apresenta como uma ferramenta útil para a análise da potência muscular dos membros inferiores, sendo de baixo custo e fácil aplicação. Apesar da mecânica de movimento dos procedimentos diferirem entre si, estudos apontam que a realização de saltos verticais e horizontais apresentam correlação moderada com a capacidade de corrida, estabelecendo uma interdependência entre potência e SP 14,15 . Considerando os estudos supracitados, a hipótese dessa pesquisa é de que a potência muscular no SH seja melhorada mediante a realização prévia de testes máximos ou próximos disso como atividade preparatória, ponderando as características bioenergéticas dos exercícios.…”
