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.

Abstract

Background: Physical condition is a term that describes the degree of fitness and health of a person's body, which includes various components such as strength, agility, durability, speed, power, balance, flexibility, and reaction. One of the primary indicators for measuring aerobic endurance capacity is VO2Max. A high VO2Max level is essential in sports that require high intensity and prolonged gameplay, such as badminton and futsal. Bojonegoro district has significant athletic potential, but there are no established normative VO2Max standards that can be used as a reference in the systematic selection and development of athletes. Objectives: This study aims to develop normative VO2Max standards as a benchmark for athlete selection in two sports, namely badminton and futsal, in Bojonegoro Regency. VO2Max is a key indicator of aerobic capacity and cardiovascular system efficiency, which is very important in supporting athlete endurance and performance. Methods: This study employed a quantitative approach using the Bleep Test instrument to measure VO2Max in 73 active athletes affiliated with sports clubs in Bojonegoro. Results: The study results showed that the average VO2Max for badminton athletes was 28.0 and for futsal athletes was 41.4, with standard deviations of 5.7 and 4.3, respectively. Based on category classification, most badminton athletes fell into the moderate category, while futsal athletes ranged from moderate to high categories. Conclusion: These differences reflect the physiological characteristics required in each sport, with futsal demanding higher aerobic endurance due to its higher intensity and longer match duration. This study produced VO2Max category norms for each sport, which can be used as a reference in the athlete selection process and in the development of targeted training programmes.
