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.

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.

The purpose of this service is to provide socialization and training at Gloria Muda Tambakrejo volleyball club, Bulurejo Village, Purwoharjo District, Banyuwangi Regency. The method used in this service is discussion and direct training (demonstration and practice) to the coaches and volleyball players of Gloria Muda Tambakrejo. The result of this activity was that the volleyball club coach Gloria Muda Tambakrejo gained new insights regarding the training program and how to train and was able to develop a training program that could be used to develop the technique and game of the Tambakrejo volleyball club. Young Gloria club players get training programmed according to the training program that suits their needs. Increased basic technical skills of passing, smash and vertical jump height of club players Gloria Muda Tambakrejo. Increased skills of passing and smash techniques and physical conditions (vertical jump) by 6.17%. For the basic technique of passing, there was an increase of 9, 53%. For the basic smash technique there is an increase of 3.20%. For the ability to vertical jump there is an increase of 3, 87%.

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.

Purpose: To find the effect of massage therapy in comparison with static stretching for reducing DOMS in tibialis anterior muscle and to assess their effect on performance of athletes with these therapies. Methodology: An experimental study was done in Imperial University Lahore for the duration of 06 months from 15 August to February 15. Participants were selected through non-probability convenience sampling technique as per inclusion criteria. Sample size was 40, from which participants were equally divided into two groups; Group-A (massage therapy) and Group-B (static stretching). DOMS were induced in tibialis anterior mucle and assessments was carried out before intervention and after applying intervention using NPRS, vertical jump height test, and sprint speed test. Findings: Both massage therapy and passive static stretching techniques were found to be effective for reducing the muscle soreness in the tibialis anterior muscle, as well as for improving players’ performance. However, within group analysis shows that passive static stretching significantly improves the vertical jump height and sprint speed duration in the athletes. Unique contribution to theory, practice and policy: The literature regarding the comparison of two techniques (massage & passive static stretching) is lacking especially their effect on tibialis anterior. This study fills the gap and will guide sports rehabilitators and trainers to devise better intervention strategies for countering the symptoms of DOMS and its effects on performance.
