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.
Highlights
Nowadays practicing physical activities is worldwide expanded among people (Tarp et al, 2016) and one of the activities most popular is Weight Lifting (Menegon et al, 2016)
Based on what was presented, the present study aims to correlate the flexibility and power variables present in the vertical jumps, through tests performed with female individuals, performing analyses of two groups: handball players (HG) and weight lifter (WL)
Squat: jump started from previous squat; Counter movement jump (CMJ): Jump using elastic energy; A: heel height; P: Power: PN: Power normalized by body mass; X Wells: Relationship with test values in Shapiro-Wilk; HG: Handball Group; weight lifters (WL): Weight Lifter Group; P-value: probability of significance
Summary
Nowadays practicing physical activities is worldwide expanded among people (Tarp et al, 2016) and one of the activities most popular is Weight Lifting (Menegon et al, 2016). It is considered that the use of EAC (elastic energy) and the greater number of sarcomeres in series (which causes the muscle as a whole to shorten more rapidly), by individuals with greater flexibility should provide better performance in jumps, especially in the use of counter movement (eccentric / concentric transition). In this way, the hypothesis presents a correlation between the performances of these physical capacities. Based on what was presented, the present study aims to correlate the flexibility and power variables present in the vertical jumps, through tests performed with female individuals, performing analyses of two groups: handball players (HG) and weight lifter (WL)
