Background: Countermovement vertical jump is a crucial skill in many sports. Plyometric training is a prevalent method to improve athletes' jumping ability. Objectives: The present study aimed to investigate the effect of a 6-week plyometric training on the kinematics of take-off and countermovement vertical jump height. Methods: Fifteen young, healthy male subjects performed plyometric exercises in three sessions per week for six weeks. Digital videos of pre-training and post-training jumps were captured. The Kinovea software was used to measure the kinematic parameters of take-off in the sagittal plane. Pre and post-training values were compared by paired sample t-test with the statistical significance level of P < 0.05. Results: Post-training results showed a higher jump height (P < 0.05), more flexed shoulder, and more extensive hip and knee at take-off (P < 0.05). Also, while hip extension velocity was decreased, shoulder flexion and knee extension velocities were significantly increased (P < 0.05). Conclusions: The 6-week plyometric training, including 720 jumps, improved shoulder flexion, and hip and knee extensions at take-off, resulting in high CMJ height. We employed plyometric training to improve the shoulder flexion and hip and knee extension velocities and increase CMJ height.

ABSTRACT The purpose of this study was to compare the effects of combined strength and plyometric training with soccer training alone on strength and power-related measurements in professional soccer players. Subjects were randomly divided into two groups: group EG (n = 14) performed heavy resistance and plyometric training thrice a week during 6 weeks training period in addition to 6-8 soccer sessions per week; group CG (n = 14) performed 6-8 soccer sessions a week. EG significantly increased (p < 0.05) ball shooting speed and agility but showed no changes in body mass. Within-subject improvement was significantly higher (p < 0.01) in the EG compared with the CG for vertical jump height, 10 and 30 m sprint times, distances covered in the Yo-Yo intermittent recovery test. Plyometric can be concurrently performed with high load muscular strength training to enhance soccer players’ explosive performances. How to cite this article Singh A, Kulkarni K, Shenoy S, Sandhu J.

In volleyball matches, there are three minute intervals between sets. Therefore, the improvement of the muscle output ratio is one of the most import foundational physical elements for the players. The purpose of this study was to investigate the effects of plyometric training on the changes in electrical signals in the lower limb muscles of male college volleyball players during continuous blocking and to examine the benefits of plyometric training on blocking agility and maximum vertical jump height. In this study, twenty elite male college volleyball players were recruited and divided into a plyometric training group (PTG) and a control group (CG). The wireless electromyography was used for data acquisition, and the electrodes were applied to the left and right rectus femoris, biceps femoris, tibialis anterior, and gastrocnemius. The median frequency was used as the measurement of the electromyographic signals during the jumping blocks. This study used covariate analysis methods, with previously measured results used as covariates to perform a two-way analysis of covariance for the independent samples. Based on the results of this study, after 6 weeks of training, the median frequency of the rectus femoris (2.13% to 4.75% improved) and that of the tibialis anterior muscles (4.14% to 7.71% improved) were significantly lower in the PTG than in the CG. Additionally, the blocking agility increased by 6.26% and the maximum vertical jump height increased by 3.33% in the PTG compared to the CG. The findings provide important insights on the neuromuscular status for volleyball players during continuous blocking jumps. Six weeks of appropriate plyometric training can facilitate the performance of volleyball players.

The aim two groups time parallel 6-week experiment was to compare selected types of plyometric training. One group trained with gradation of external weight loading in eccentric phase (EXP1) and the second group increased drop height (EXP2) during drop jump training. We compared their effects on changes in selected strength abilities. We assessed the level of countermovement vertical jump height (CMJ), standing vertical jump height (SJ) and average force gradient in squat exercises with the knee joint in 90 ° by maximal isometric contraction at intervals of 0-50 ms (RFD50) and 0-200 ms (RFD200). The results showed that in CMJ EXP1 had improved by 1.01 cm (3.5%) (p<0.01). EXP2 improved by an average of 1.78 cm (5.5 %) (p<0.05). SJ in EXP1 average improved by 0.94 cm (3.5 %) (p = n.s.) in EXP2 by 1.91 cm (6.6 %) (p<0.05). In RDF50 the average increase observed after a period of training in EXP1 1.03 N.ms-1 (26.08 %) (p = n.s.) and EXP2 0.57 N.ms-1 (16.39 %) (p<0.05). In the EXP1 RFD200 the average increase was 2.51 N.ms-1 after a period of training (20.91 %) (p<0.01), while on average EXP2 improved by 1.05 N.ms-1 (10.04 %) (p = n.s.). Based on these results we recommend to improving of vertical jump height with a countermovement and force gradient in longer intervals (200 ms) to apply the external weight in the form of small dumbbells in eccentric phase of drop jump training. To standing jump height development and shorter time intervals of force gradient (50 ms) is recommended to use a gradual increase in height of drop in plyometric training.
