Abstract

Mastering forehand and backhand smash techniques in table tennis remains a challenge for junior high school students, mainly due to the limited availability of learning media that is interesting, simple, and supports repetitive practice. This study aims to examine the effectiveness of the innovative Botolsis Smash learning media, which utilizes used bottles and height-adjustable tripods, in improving students' forehand and backhand smash skills in table tennis. The method used was a quasi-experiment with a one-group pretest-posttest design, involving 30 eighth-grade students from SMPN 1 Sumberrejo as research subjects. Data were obtained through a smash skill test that had been tested for validity and reliability, then analyzed statistically using a paired sample t-test using SPSS version 30. The results showed a significant increase in backhand smash (p < 0.001) and forehand smash (p < 0.001) skills, with higher posttest scores compared to pretest scores. The conclusion of this study indicates that the Botolsis Smash is effective as a contextual, economical, and applicable training tool in improving basic table tennis techniques, thus serving as an alternative teaching medium for physical education in schools.

Abstract

This study was motivated by the phenomenon observed in the field, where approximately 35% of athletes still experience difficulties in executing smashes, presumably due to suboptimal specific physical training programs. The study aims to analyze the relationship between arm, leg, and abdominal muscle strength and volleyball smash ability, as well as to identify the relative contribution of each variable. The method use is quantitative correlational with a population of 30 athletes from the Bina Voli Sepanjang Masa Club (total sampling). Data were collected through physical tests (push-ups, vertical jumps, sit-ups) and smash skill tests, analyzed for using multiple linear regression. The results showed a very strong relationship with a coefficient of determination (R²) of 0.965, meaning that 96.5% of the variation in smash ability could be explained by these three variables. Partially, leg muscle strength contributed the most (31.0%), followed by arm muscles (26.3%), and abdominal muscles (5.5%). The study concluded that smash ability is greatly influenced by the athlete's physical condition, with the recommendation that training programs prioritize strengthening leg explosive power, supported by increased arm strength and abdominal muscle stability.
