Effects of plyometric training on grass surface and concrete surface on jumping performance among volleyball athletes

Abstract

The purpose of this study was to compare the effects of 4 weeks plyometric training on grass surface group and concrete surface on jumping performance among volleyball athletes. The vertical jump was evaluated in two types of jump; squat jump (SJ) and countermovement jump (CMJ). The result of this study indicates that the 4 weeks intervention showed a significant improvement in post test on SJ and CMJ (p < 0.05) for both grass surface and concrete surface. However, in comparing the grass surface and concrete surface, there was no significant difference (p > 0.05). These findings suggest that plyometric training on different surfaces may be associated with similar training-induced effects on the neuromuscular factors which are related to the efficiency of the stretch-shortening cycle.

The Effect of Plyometric Training in Volleyball Players: A Systematic Review

“…Also, for the same test in under-22 women players, an improvement of 27.6% was recorded after 12 weeks of plyometric training [48]. In a study conducted in both men and women players (~21 years old), it was observed that plyometrics training interventions carried out on grass and on concrete for four weeks promoted improvements of 3.34 cm and 3.67 cm, respectively, in the counter-jump performance of players [50].…”

“…When performing a squat jump, a pause occurs during the amortization phase, leading to the dissipation of elastic potential energy and a decrease in the potentization effect based on SSC [57]. In a study that compared plyometric training (i.e., young adults; men and women) carried out on grass with plyometric training carried out on concrete, improvements of 3.17 and 2.17 cm, respectively, in squat jump performance and of 3.34 and 3.67 cm, respectively, in counter-movement were observed [50]. However, in a study which involved a 12-week training period on young adult men and which tested more than one type of jump, it was observed that improvements were slightly greater for the squat jump (+5.93 cm) than counter-movement (+4.98 cm) and drop jumps (+4.83 cm) [59].…”

“…Another common omission of information observed throughout the included studies was the type of surface that the tests were conducted on; this factor may affect the outcomes of a training program. However, in a study that tested the effects of plyometric training completed on grass or on concrete, it was observed that both training types improved the jumping performance of volleyball athletes, with no significant differences found between the two groups [50]. Also, when testing plyometric interventions in a non-solid aquatic environment, meaningful improvements in vertical jump performance were observed [42].…”

Is COVID-19 infection decreasing the sports performance of the volleyball players? A pilot study

“…Ramlan et al [22] evaluated the effect of plyometric training on performance and showed 3.17 cm improvements in men's squat jump performance, 3.34 cm in countermovement. Velickovic et al [23] investigated a 12-week training period effect with several jump tests on men and demonstrated improvements in the squat jump 5.93 cm countermovement 4.98 cm and drop jumps 4.83 cm.…”

Effects of Plyometric Jump Training in Sand or Rigid Surface on Jump-Related Biomechanical Variables and Physical Fitness in Female Volleyball Players

“…The CMJ velocity take-off on SsG (5.6%) was greater than RsG. A possible interpretation for the effects of PJT on soft surfaces is that it necessitates a potent concentric contraction at push-off, generated by a discharge of elastic energy from the ankle to produce extra energy to overcome the reaction force of the surface [ 39 ]. The CMJ take-off velocity induces a sufficient force to jump high, which is explained by the increasing velocity of the employment of motor units in the leg extensor muscles to absorb the eccentric impulse and run-up the concentric impulse [ 40 ].…”
