<b>Correlation between flexibility and muscular power in vertical jumps in women practitioners handball and weight lifters

Abstract

The present study has the objective to correlate the variables of flexibility and muscle power present in the vertical jumps, through tests done with female individuals, performing analyzes about two groups: Handball players (HG); weight lifters (WL). Initially, the protocol consisted on the performing of the flexibility test at Wells Bank. Subsequently, the jump test was performed, using the Counter movement jump (CMJ) and Squat jump (SJ). About the study groups, it can be observed that they have similar physical characteristics, but practice times (HG = 9.25 ± 3.28 versus WL = 1.85 ± 1.47 years) and weekly hours of activities (HG = 3.33 ± 1.23 versus WL = 5.29 ± 1.81 hours) were distinct. In the execution of SJ for HG, a high correlation was presented for all variables (Height 0.615; Power 0.718; Standard power 0.618). It also presented a high correlation in the non-normalized power (0.688) in CMJ. WL did not present a significant correlation for any of the variables. Based on the findings of the present study, jump test results have correlation with variables of flexibility, muscle power and handball players. However, there is no correlation for any variable for weight lifters.

Contribution of Leg Muscle Power, Leg Flexibility and Balance to Kedeng Smash Ability Sepaktakraw Game

“…It means that leg muscle power variables and leg flexibility as independent variables have a contribution of 24.50% to kedeng smash ability as a dependent variable. The jumping tests have shown correlation between variables of flexibility and power in handball athletes [13]. The results from the field study showed that the combination of leg muscle explosive power (X1) and flexibility (X2) have significant contributions to lay-up shoot skills (Y).…”

Os efeitos da criocompressão intermitente no desempenho funcional de acadêmicos de fisioterapia: Estudo piloto

“…Os saltos verticais são amplamente utilizados quando se tem o objetivo de avaliar o desempenho funcional dos membros inferiores (Barbosa et al, 2018). Com frequência o SJ e o CMJ são conjuntamente listados nos estudos por permitirem analisar o desempenho sob a perspectiva de um recrutamento muscular puramente concêntrico no SJ e avaliar a influência de um benefício do componente muscular elástico produzido no ciclo alongamento-encurtamento resultante das contrações excêntrica e concêntrica em sequência durante o CMJ (Lima, 2022).…”
