Relationships of the 5-Jump Test (5JT) Performance of Youth Players With Volleyball Specific’ Laboratory Tests for Explosive Power

Abstract

Volleyball involves movements with and/or without horizontal approaches (i.e., spike jumps, jump setting, blocking). The 5-jump test (5JT) was suggested to assess lower limb explosive power of athletes competing in some disciplines (e.g., soccer, judo, running). It appears that no previous study has investigated the 5JT performance components in volleyball players. This study aimed to test the relationship between 5JT performance and two specific laboratory tests for explosive power (i.e., countermovement jump [CMJ] and squat jump [SJ]). Forty volleyball players (boys, mean age: 12.4 ± 0.8 years) were tested for 5JT, CMJ, and SJ tests. 5JT performance was expressed in absolute terms (m), and relative to leg length (5JTLL) and body mass (5JTBM). The SJ and CMJ tests were evaluated using the optojump photoelectric cells and the following data were collected: peak power (Pp) of jump (W, W.kg-0.67), peak jumping force (Fpeak, N), peak jumping velocity (Vpeak, m/s), peak heights of CMJ and SJ (CMJH and SJH, respectively, cm). Only significant ( p < .05) Pearson product-moment correlations ( r) > 0.30 were considered. 5JT performance was significantly correlated with SJ, Vpeak ( r = 0.90), SJH ( r = 0.88), Pp [W.kg-0.67 ( r = 0.86), W ( r = 0.72)], Fpeak ( r = 0.45); and CMJ, Vpeak ( r = 0.82), CMJH ( r = 0.80), Pp [W.kg-0.67 ( r = 0.89), W ( r = 0.85)], Fpeak ( r = 0.73). 5JTLL values were significantly related to SJ, Pp [W ( r = 0.81), W.kg-0.67 ( r = 0.74)], Vpeak ( r = 0.82); and CMJ, Pp [W ( r = 0.73), W.kg-0.67 ( r = 0.84)], Vpeak ( r = 0.75), Fpeak ( r = 0.67)]. 5JTBM values were significantly related to SJ, Pp (W, r = −0.43). To conclude, in youth volleyball players, the 5JT may be viewed as an explosive strength diagnostic instrument under field circumstances.

The Ankle Joint Range of Motion and Its Effect on Squat Jump Performance with and without Arm Swing in Adolescent Female Volleyball Players

“…Jumping is considered to be a crucial element in volleyball [ 1 ], as it is demonstrated in a variety of skills, such as the spike jump, the block jump, the jump service, and the overhead set with a jump. Due to the importance of jumping in volleyball, vertical jumping tests are custom for the assessment of performance of volleyball players [ 2 , 3 , 4 ]. The most common tests are the squat jumps (SQJ), the countermovement jumps (CMJ), the drop jumps (DJ), and series of repetitive jumps [ 3 ].…”

The Effect of Six-Week Plyometric Training on Enhancing Sports Performance of Adolescent Students

“…For example, Smilios et al (2005) reported an acute increase in CMJ height following 1 and 2 sets of half-squat exercise with intensity set at 60% 1 RM. Several studies have mentioned the effectiveness of PT in increasing strength and vertical jump performance, with one study suggested that the increase muscular power of lower limb, was again, might be due to the force variable in CMJ (SSC mechanism), coupled with the production of high velocity during vertical jump take off (Ben Ayed et al, 2020). In addition to that, plyometric training is able to enhance coordination (de Villarreal et al, 2009), therefore it induces a neuromuscular adaptation that improve power production (Chelly et al, 2010).…”

“…Strength and power are one of the most important skills in sports, where individuals qualified of these factors would highly contributes to their performance in the field (Váczi et al, 2013). Thus, plyometric training is often used by athletes playing in sports that required explosive movements such as volleyball (Ben Ayed et al, 2020), soccer (Sedano et al, 2011), and basketball (Ivanović et al, 2022).…”

The impact of the relations between the explosive power of the lower limbs measured by a force-velocity test versus field tests (horizontal jump, speed test and agility test) in young North African volleyball players.

“…In previous literature, successful COD ability involved prerequisites such as lower-body strength and power (15). As a result, the more these qualities are developed for players, the more chances they have to succeed (7,11). This observation led the researchers to concentrate on determining the success of complex physical parameters in order to improve them with speci c training (4,11,15,(18)(19)(20)(21).…”

This observation led the researchers to concentrate on determining the success of complex physical parameters in order to improve them with speci c training (4,11,15,(18)(19)(20)(21). To be successful, these skills depend heavily on the capacity to generate rapidly muscle strength or power in the lower body (4,7,22).…”
