Selisih posstest sebesar 1,75 cm. EFFECT OF PLYOMETRIC BOX JUMP AND PLYOMETRIC STANDING JUMP TOWARD VERTICAL JUMP ABILITY IN VOLLEY BALL CLUB ATHLETES AbstractThis study aims to determine: 1) is there any influence of Box jump training on vertical jumps of Ganevo male athletes aged 14-17 years, 2) is there any influence of standing jump exercises on vertical jumps of Ganevo male athletes aged 14-17 years, 3) is there any types of exercises give effective effect toward vertical jump of male athlete Ganevo aged 14-17 years. This research is an experiment study using two groups pretest-posttest design. The instrument in this study was a vertical jump test with a reliability of 0.99 and a validity of 0.989. Subjects in this study were Ganevo Volleyball Club Athletes Aged 14-17 Years, 24 Athletes in total as subjects. Data analysis techniques used the t test with a significance level of 5%.The results of the study concluded: (1) there was an effect of plyometric box jump training on the vertical jump of male volleyball athlete Ganevo Age 14-17 years, with t count (8,660)> t table (2,201), and the Significance value (0,000) < of (0 , 05), (2) there is the influence of plyometric standing jump training on the vertical jump of male volleyball athlete Ganevo Age 14-17 years, with t arithmetic (3,522) > t table (2,201), and the Significance value (0.005) < of (0 , 05), (3) plyometric standing jump training is better to increase vertical jump for volleyball athletes of Ganevo men aged 14-17 years, with t arithmetic (2,133)> t table (1,720), and significance value (0.026) <of ( 0.05). Post-test difference of 1.75 cm.

The Difference

This study aims to determine the extent of the difference in effect between knee tuck jump and half squat jump training on the ability to smash kedeng in sepaktakraw games. By using the field experiment method. The population used is male students of Southeast Sulawesi SMANKO with a sample of 60 people taken by Proposive random sampling. The data analysis technique used is the t-test at 95% significance level. The results showed that; (1) There is a significant effect of knee tuck jump training on the ability to smash kedeng in sepaktakraw games on Southeast Sulawesi SMANKO students, proven to = 13,446> tt = 2,045. There is a significant effect of half squat jump training on the ability of the Kedeng smash in sepaktakraw games on Southeast Sulawesi SMANKO students, proven to = 10.478> tt = 2.045. There is a significant difference in effect between training on the ability to smash kedeng in sepaktakraw games on Southeast Sulawesi SMANKO students, proven, to = 9,970> tt = 2,000.

This research is a field experimental study with a 2 x 2 factorial design. The population is all students of the Faculty of Sport Science, Jambi State University with SportsTraining Education samples with a sampling technique is a proportional sampling of 40 people. The data analysis technique used is Analysis of Variance (ANAVA) at a significant level of 95%. By looking at the existing problems, the results obtained from the data processing shows that: there is no significant difference in effect between hurdles and side jump exercises on the ability of heading balls in football (Fo = 0.939> Ft = 4.11). There is a significant difference between the power of high limb muscle explosions with low limb muscle explosiveness to the ability of heading balls in football (Fo = 17,976> Ft = 4.11). For athletes who have high leg muscle explosive power, there is a significant difference in effect between goal jump training and side lomato training on ball heading abilities in football (to = 6.034> tt = 1.73). For athletes who have low leg muscle explosive power, there is a significant difference in effect between hurdles and side jump exercises on heading ball abilities in football (to = 12,357> tt = 1.73).
