This study aims to determine whether there is 1) The effect of plyometric training jumping over a kun with two legs to the side, 2) The effect of the plyometric training jumping over a kun with two legs in a zig-zag manner, 3) Comparison of the plyometric exercise jumping over a kun with two legs sideways and in a zig-zag manner on leg muscle power for male students of class VIII A SMP Negeri 1 Rambah, Rokan Hulu Regency. This type of research is a quasi experiment. The population was all male students of class VIII A SMP Negeri 1 Rambah, Rokan Hulu Regency, totaling 12 people. The sampling technique used in this study was total sampling, namely the entire population of male students of class VIII A SMP Negeri 1 Rambah, Rokan Hulu Regency. The instrument used in collecting data was the Standing Broad Jump test. The data analysis technique used was the t-test, where 1) The effect of the plyometric training jumping over a kun with two legs to the side is 4.27, 2) The effect of the plyometric training jumping over a kun with two legs in a zigzag manner is 5.97, 3) Comparison plyometric exercise jumping kun with two legs to the side and zigzag the leg muscle power of male students class VIII A SMP Negeri 1 Rambah, Rokan Hulu Regency is 2.36 with t table is 1.81. So from the two exercises given there are significant differences.

This study examined the effects of incorporating 8 weeks of biweekly upper limb loaded plyometric training (elastic band) into the in-season regimen of handball players. Trial participants were assigned between control (n = 15, age: 18.1±0.5 years, body mass: 73.7±13.9 kg) and experimental (n = 14, age: 17.7±0.3 years, body mass: 76.8±10.7 kg) groups. Measures obtained pre- and post- included a cycle ergometer force-velocity test, ball throwing velocity in three types throw, 1-RM bench press and pull-over, and anthropometric estimates of upper limb muscle volumes. Gains in the experimental group relative to controls included absolute muscle power (W) (Δ23.3%; t-test p<0.01; d=0.083), relative muscle power (W.kg-1) (Δ22.3%; t-test p<0.01; d=0.091), and all 3 types of ball throw (Δ18.6%, t-test p<0.01, d=0.097 on jumping shot; Δ18.6%, t-test p<0.01; d=0.101 on 3-step running throw; and Δ19.1%, t-test p<0.01, d=0.072 on standing throw). Furthermore, a significant improvement by time interactions was observed in both groups on 1-RM bench press and pull-over performance. However, upper limb muscle volumes remained unchanged in both groups. We conclude that adding biweekly elastic band plyometric training to standard training improves measures important to game performance. Accordingly, such exercises can usefully be adopted as a part of handball training.

The development of muscle power should be taken into account in soccer training. The aim of this study was to evaluate the influence of a 6-week of mixed power training on the level of the motor skills of the lower limbs of young soccer players. The training was conducted during the starting period. The study included twelve 16-18-year-old players who regularly participated in specific soccer trainings and played in regional competitions. Their basic anthropometric features were measured. The assessment of the power of the lower limbs was carried out using two jump tests: CMJ and SJ. The maximum anaerobic power was calculated and was expressed in relation to body weight and lean body mass. In addition, Drop Jump tests were performed from three different heights on the basis of which RSI reactive strength index were calculated. On completion of the training program an increase in the level of the results of all the tests was observed: SJ (cm) (cohen's d: 0.43), CMJ (cm) (cohen's d: 0.33), SJPmax (W/kg) (cohen's d: 0.43), CMJPmax (W/kg) (cohen's d: 0.30), SJPmax (W/LBMkg) (cohen's d): 0,57), CMJPmax (W/LBMkg) (cohen's d: 0,44), RSI 0,2 (cohen's d: 0,59), RSI 0,3 (cohen's d: 0,45), RSI 0,4 (cohen's d: 0,58). An additional six-week ballistic-plyometric training program, used as a supplement to the basic training plan during the start period, resulted in an increase in the motor skills of the lower limbs of young soccer players. The application of combined ballistic and plyometric training methods helps to improve the strength and speed potential of young soccer players.

This study aims to find out better plyometric exercises between depth jump and jump to box plyometrics exercises on leg muscle power in volleyball smash games in Mts Salafiah extracurricular. This research uses experimental methods with the design of "pretest-posttest one group design". The population in this study were volleyball students in Mts Salafiah extracurricular totaling 30 students. Samples taken from the results of the sampling technique that is purposive sampling, with criteria namely; (1) actively participating in extracurricular activities in Mts Salafiah, (2) registered as extracurricular participants in Mts Salafiah, (3) willing to take part in the training during the research. Based on these criteria, there were 20 students who met them. The instrument used for the jump height test is the vertical jump. Data analysis using t test. The results of the analysis showed that: (1) There was an effect of depth jump plyometric training on leg muscle power in volleyball smash games in Mts Salafiah extracurricular, with t count 3.405> t table 2.23, and significance value 0.008 <0.05, increase in the average difference in value 5.40 cm. (2) There is an effect of jump to box plyometric training on leg muscle power in volleyball smash in Mts Salafiah extracurricular, with t count value 2. 945> t table 2.23, and significance value 0.016 <0.05, increase in mean difference of 3.70 cm. (3) Jump to box plyometric training is better than depth jump plyometric training on leg muscle power in volleyball smash games in Mts Salafiah extracurricular, with an average difference of 10.50 cm

PURPOSE: Muscle strength, power, speed, postural stability, and anaerobic power are important physical fitness factors required to perform well in a taekwondo competition. This study aimed to investigate the effects of 8 weeks of core balance and plyometric training on physical fitness in young taekwondo athletes.METHODS: Nine young taekwondo athletes participated in this program. Body composition and relative fitness (muscle power, core strength, agility, postural stability, anaerobic power, and isokinetic muscle function) were measured before and after training. Data were analyzed using IBM SPSS Statistics version 23.0 (IBM Corp., Armonk, NY, USA). A paired t-test (pre vs. post) was used for the analysis.RESULTS:The core strength measured by the sit-up count changed significantly after training (<i>p</i><.05). In case of postural stability, the right absolute reach distance in the Y-balance test improved significantly after training (<i>p</i><.05). In case of anaerobic power, the mean power (<i>p</i><.01) and the peak power (<i>p</i><.01) increased significantly after training.CONCLUSIONS:We demonstrated that 8 weeks of core balance and plyometric training enhanced core strength, balance, and anaerobic power in young taekwondo athletes. Our results suggest that core balance and plyometric training are effective in improving muscle strength, core strength, balance, and anaerobic power.

The purpose of this study was to know the effect of plyometric training and weight training with reaction speed toward limb muscle of male volleyball players. The method of the study was treatment design level 2 x 2 , where the independent variable was classified in two parts. The findings were: (1) overall, there is different significant effect of plyometric training and weight training toward limb muscle power of volleyball players (Fh = 0.58 <Ft = 4.00), (2) there is interaction between training methods and reaction speed toward limb muscle power of male volleyball players  of SMA IQRO IT Bengkulu city (Fh = 28.39> Ft = 3.97), (3) volleyball players who have high speed reaction have better limb muscle power if using training method rather than training with the Plyometric training method (Fh = 5.35> Ft = 4.01). (4) Volleyball players who have low reaction speed have better limb muscle  power if trained by weight training method (fh = 5.12> ft = 4.01). In Conclusion, volleyball players who have high reaction speed are more efficient trained by weight training, meanwhile volleyball players who have low reaction speed are more efficient trained by plyometric training Keyword: Plyometric Exercise Method, Reaction Speed, Power of Leg Muscles.
