The Effects Of Strength and Plyometric Training on The Development of The Explosive Power of U-17 Youth Volleyball Players In Amhara Region Ethiopia Astatkie, Bogale The purpose of this study was to examine the effects of plyometric and strength training interventions on the explosive power output of male volleyball trainees. A total of 68 project players participated in the study and were randomly allocated into four groups. The first group participated in plyometric training, the second and third groups took part in strength and combined training respectively. The fourth group, the control group, had participated only in the usual volleyball training program. The training session was conducted 3 times per week for 90 minutes, and the entire training intervention lasts for 12 weeks. To reveal the effect of each of the three training interventions in improving the explosive power of young players, the researcher measured the spike jump (m), block jump (m), standing broad jump (m), pull-up (rep) and sit-up (rep). The outcomes show a significant difference between the four groups (Pre vs. Post), and the combined group scored the most prominent result of all the other groups. The current study indicated that 12 weeks of involvement training meaningfully enriched explosive power of young volleyball players. Thus, it is concluded that a 12-weeks Plyometric and Strength Training intervention with a range of exercise intensity from 60% to 90% can positively impact the explosive power of the lower legs and thus boost the vertical jumping abilities.

Effects of Strength Training Combined With Plyometric Training on Some Selected Physical Fitness oualities And Technical Skills Among Adet U-17 Male Volleyball Project Player Yihenew, Wubie The purpose of this study was to investigate the effect of strength training combined with plyometric training on some selected physical fitness qualities and technical skills among Adet U-17 volleyball project players. The study employed pre test post test Experimental research design. 26 male volleyball players of Adet with the age of (EG=16.08±0.760, CG =16.00±0.707) were randomly assigned into 2 equal groups. Both the experimental group (EG, n = 13) and control group (CG, n = 13) participated in the regular volleyball training, but only EG performed additional combined strength and plyometric training for eight weeks, with 3 sessions per week, each lasting 40 to 60 minutes. Subjects were measured on, explosive power, 30m sprint time, over arm passing and over arm service on two occasions first before administration of the training as pre-test and after eight weeks of the training as post-test. The data collected from the study subject was analyzed using SPSS version 26 software by paired t-test with level of significant 0.05. The results showed that combined strength and plyometric training significantly improved explosive power, over arm pass, and over arm serve in EG at (p<0.05). Similarly, sprint time was significantly reduced (p<0.05). But no significant differences were found in all of the variables in CG (p>0.05). Based on this finding, it can be concluded that eight weeks combined strength and plyometric training has positive effect on improvement of volleyball skill performance and physical fitness variables of volleyball players. Therefore, this type of training method is suggested to volleyball players and coaches for improving physical fitness and performance skill.

Effects of Callisthenic Versus Plyometric Training on Volleyball Related Fitness Variables and Passing Accuracy: The Case of Muja Mariam General Secondary School Male Students Yemataw, Filatie The purpose of this study was to investigate the comparative effects of callisthenic and plyometric training on speed, agility, explosive power and passing accuracy. To achieve the objective of the present study, quantitative research approach and true experimental research design were employed. In this study, The study population were little; all the 36 Muja Mariam general secondary school male student volleyball players were selected using comprehensive sampling technique with the age of (CG=17.92±1.240, PG=17.42±.900 and CoG=17.7500±1.28806) were assigned into three groups using simple random sampling technique. Out of the three groups, two of them were assigned as experimental groups (callisthenic and plyometric group) and the rest as control group. Both experimental groups (CG, N=12 and PG, N=12) participated in 12 weeks of callisthenic and plyometric training, 3 days per week, each session lasting 50-60 minutes respectively. But the control group (N=12) did not participate in any of training except the regular volleyball training. Data were collected through pre and posttest measurements of each fitness test like 35 m sprint test, agility zig zag test, vertical jump test and overhead pass to target test. Collected data from the study was analyzed through the use of SPSS version 20 software program. Paired sample t-test and independent sample test with level of significant p<0.05 were used for analysis. The result in the study shown that the interventions of 12 weeks callisthenic and plyometric training significantly improved the speed, agility, explosive power and passing accuracy of the students at p<.05 level of significance but no result change in control group. The plyometric training group significantly improves the speed, agility and explosive power of students than callisthenic training at p<.05 and the 12 weeks callisthenic training significantly improves the passing accuracy of students than plyometric group. Among plyometric and callisthenic training, plyometric training has been found better to improve the above mentioned fitness variables. So, the researcher recommended that, it is better to use plyometric training rather than callisthenic training to gain better improvement of speed, agility and explosive power and for better passing accuracy callisthenic training is better
