Effects of Six-Week Plyometrics on Vertical Jumping Ability of Volleyball Players
The study was designed to find the six-week Plyometrics effect on vertical jumping ability of state level Volleyball players. Total twenty (n=20) Volleyball players of Amritsar district were selected. Vertical jumping ability was dependent variable and Plyometric training was independent variable. Two groups were made by dividing subjects randomly, Experimental group (E; n =10) and Control group (C; n=10). Experimental group was given six week Plyometric training treatment while control group participated only their routine program. For the data collection, Sargent jump test was used. Pre-test and post-test were taken. To analyze data, t-test was used to test the effect of Plyometric treatment at 0.05 significance level. The outcomes of study reveals that in Experimental group, the difference was statistically significant but no significant difference found between means of control group. Conclusion: Identification of Plyometric training program as more beneficial and effective than general training program and have more positive effect on vertical jump performance.
The effects of plyometric training on the development of the jumping frequency of volleyball players
With the aim of evaluating the effects of plyometric training on the development of jumping agility, an experimental research program was carried out on a sample of 38 cadet volleyball players. Following the general principles of plyometric training, individual training programs were constructed. In order to evaluate the effects of plyometric training on the development of jumping agility, six variables were used. For the purpose of this research, all six tests for the evaluation of jumping agility were validated. The experiment was realized in the second part of the preliminary period, and lasted for six weeks with two to three training sessions per week. The training of the control group involved technical-tactical exercises. The data were processed with the help of a univariate and multivariate analysis of covariance. On the basis of the research results and the discussion, we can with great certainty conclude that the exercise model that was used, as the basic factor of the expe...

Volleyball is one of the most played games in Indian School going population. Vertical jump height is an essential part in volleyball which can be achieved by strengthening the lower leg musculature. Thus the 6 weeks plyometric training protocol is added to see its results on the strength of lower leg musculature among high school amateur male volleyball players. The subjects (n = 40; age = 10-16 years; mean = 12 ± 1.00 years) jumping reach Height (mean) = 169.00 ± 1.00 cm) were divided equally into 2 groups called as group A (Experimental) and group B (Control) respectively by simple random sampling method. Group A received the 6 weeks plyometric training protocol and conventional training while group B received only conventional training. Sargent jump test was used to assess the jump heights pre and post at the end of 6 weeks. Unpaired t-test was used to compare the results between the groups. Group A showed significant increase in the difference between the jumping and standing reach heights at the end of 6 weeks (mean difference in the height = 34.25 cm; p-value < 0.05) than in Group B (mean difference in the height = 25.15 cm; p-value < 0.05) at the end of 6 weeks. Also, there is significant improvement in Jumping reach height in Group A (pre = 188.05 cm; post = 203.00 cm) than in Group B (pre = 187.20 cm; post = 195.15 cm). Group A showed 43.65% (mean = 34.25 cm; SD = 7.59) increase while Group B achieved 31.61% (mean = 25.15 cm; SD = 3.73) increase with their initial vertical jump height Both the training protocols are effective in improving vertical jump height but the 6 weeks plyometric training protocol is more effective in improving vertical jump than the conventional training among high school amateur male volleyball players.
Effect of plyometric training on explosive strength of volleyball players
2019
The purpose of the study was to identify the effect of Plyometric training on explosive strength of volleyball players. Plyometrics is also known as jumping training. It is a training technique designed to improve muscular power and explosiveness. For this purpose thirty players were randomly selected from the Spider Volleyball Club in Puducherry and their age ranged from 14-18 years. The selected subjects were randomly assigned to experimental group A and control group B. Each group consisted of 15 subjects each. Group A acted as experimental group and were subjected to trained for six weeks and group B acted as control group. The variables selected for this study was upper body explosive strength and lower body explosive strength. The testing tool used for measuring upper body explosive strength was 2kg medicine ball throw and for lower body explosive strength standing broad jump test was administered. The results of pre and post-test were statistically treated by using ANOVA.

The purpose of the study was to find out the effect of plyometric training and circuit training on selected physical and physiological variables among male volleyball players. Twenty four male volleyball players aged between 18 to 25 years were selected randomly. They were divided into two groups (two experimental and one control group) the experimental group I was given plyometric training and experimental group II was given circuit training for six weeks and control group was not allowed to participate in any training programme. Pretest was conducted dependent variables such as speed, muscular endurance, flexibility, agility, explosive strength, vital capacity and anaerobic capacity at the beginning before the experimental treatment and posttest was taken after the experimental treatment. The data were analyzed by applying dependent 't' test and ANCOVA. The results revealed that the plyometric training and circuit training had significantly improved the speed, muscular endurance, flexibility, agility, explosive strength, vital capacity and anaerobic capacity.
Plyometric Training Effects on Volleyball Athletes Power
Proceedings of the 3rd Yogyakarta International Seminar on Health, Physical Education, and Sport Science in conjunction with the 2nd Conference on Interdisciplinary Approach in Sports, 2019
The purpose of this study was to determine the effects of plyometric training, consisting of both dynamic and static plyometric training, on power of volleyball athletes. Eight-teen volleyball athletes were recruited as samples. The sample consisted of two groups, namely dynamic plyometric and static plyometric group. In addition, power performance was assessed by standing broad jump test. This study used experimental research design. Paired t-test was employed to find out the effects of plyometric training, which consists of dynamic and static plyometric training, on power of volleyball athletes while independent t-test was used to find out different effect of dynamic and static plyometric training. The result showed that there was a significant effect of dynamic plyometric training on power (p= 0.028); no significant effect of statistic plyometric training on power (p= 0.540), and a significant different effect of dynamic and statistic plyometric training on power (p= 0.000). The result suggests that dynamic plyometric training is effective to improve power.

We aimed to examine the effects of plyometric jump training (PJT) on measures of physical fitness in amateur and professional volleyball players. A systematic electronic literature search was carried out in the databases PubMed, MEDLINE, Web of Science, and SCOPUS. Controlled studies including pre-to-post intervention tests of physical fitness and involving healthy volleyball players regardless of age and sex were considered. A random-effects model was used to calculate effect sizes (ES) between intervention and control groups. Moderator analyses considered programme duration, training frequency, total number of training sessions and jumps, participants' sex, age, and expertise level. The Physiotherapy Evidence Database scale was used to assess the methodological quality of the included studies. Eighteen moderate-to-high quality (median of 5 PEDro points) studies were eligible, comprising a total of 746 athletes. None of the included studies reported injuries related to the PJT ...
