Abstract

The necessity of power in volleyball is to support the game's technique. Volleyball players' leg muscles must be strong enough to sustain techniques like smashes, blocks, and serves. Proper workouts, such as plyometric exercises, should reinforce the importance of muscular leg power. This study aims to determine the impact of plyometric side-to-side box shuffle and leap to box exercises on leg muscle power and determine which workouts are more successful in developing volleyball participants' limb muscular explosiveness. This is an experimental study with a "Two Groups Prettest Posttest Design" as the research design. The sample size for this study was up to 30 female athletes, with Purposive Sampling being employed as the sampling strategy. The samples were randomly split into two groups. The vertical leap test was utilized to determine the strength of the limb muscles in this research. Normality tests, homogeneity tests, and t-tests are used in data analysis. The results revealed a sig value of 0.918, indicating a difference in enhancing muscular leg strength in footballers between side-to-side box shuffle and leap to box workouts. Jump to box training improves muscular leg strength more than side-to-side box shuffle training, with a ratio of rises of 22.00 percent and 16.73 percent, respectively.

Abstract

This study aims to find out how effective the success of application-based basketball scorers is in recapturing all events, both personal foul violations, foul teams, score / points etc., according to the FIBA scorer fortofolio in the FIBA match rulebook. The research method used is an experimental method by looking at the differences in the results of the actual scorer records with the results of application-based scorer records. The sample in this study is a student of the Faculty of Sports, Medan State University who took a course in basketball game management. From the results of the research data obtained for personal foul data obtained the value of r Q1 (Quarter round)= 0.9656, Q2= 0.7281, Q3= 0.8668 and Q4= 0.8150, for the foul team data obtained the value of r Q1= 0.9656, Q2= 0.7281, Q3= 0.8668 and Q4= 0.8150, for the data of point 1 score obtained r value Q1= 0.9161, Q2= 0.8989, Q3= 0.9444 and Q4= 0.9048. For the time out data carried out by each team, the values of r Q1 = 1, Q2 = 1, Q3 = 1 and Q4 = 1 from the results of the reliability test, it can be concluded that the scorer application for basketball games can be used to replace the manual scorer that has been used and the level of efficiency is also very high judging from the reliability test category which ranges from strong to very strong.
