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

Sedentary lifestyles and conventional physical education limit the motor development of primary school children. This community service program aimed to improve the physical health and movement coordination of pupils at MI ICP Nurul Ulum Bojonegoro through the introduction of creative, enjoyable, and educational motor games. The program applied a participatory and educational approach across five stages, namely socialization, teacher training, technology and innovation adoption, mentoring and evaluation, and program sustainability. The core innovation was the Interactive Motor Learning Innovation Package (PIMI), which combines simple physical equipment with QR code video tutorials and a Merdeka Curriculum based motor game module. Up to the midpoint of implementation, the team completed initial coordination, socialization and the formation of a healthy school team, teacher training, module preparation, equipment procurement, and most field mentoring. Preliminary results show high student enthusiasm, improved teacher capacity in designing motor activities, and the emergence of more varied physical activity habits. The program demonstrates that an accessible and low-cost technology can be absorbed independently by partner teachers and holds strong potential to be replicated as a model of a healthy, game-based school in Bojonegoro.

Abstract

The purpose of this study is to ascertain how a modified stick can enhance rounders players' ball-hitting abilities among fifth-grade students at MI Islamiyah Tulungagung through the use of learning media in the form of a modified stick. Initial observations showed that most of the 30 students were still in the low category, with pretest scores ranging from 30 to 40. This study used a one-group pretest–posttest design and a quantitative methodology, in which the entire population was used as the sample through a total sampling technique, and the research instrument was a kasti ball hitting test, while the treatment was given over four sessions through stick swing exercises of 5 times × 2 repetitions and hitting balls at slow, medium, and fast speeds using a cricket bat. The results of the descriptive analysis showed an increase in the average score from 56.67 in the pretest to 64.33 in the posttest, with the score range changing from 30–40 to 80–90. The Shapiro–Wilk normality test proved that the data were normally distributed, with p = 0.090 for the pretest and p = 0.107 for the posttest, and the Paired Sample t-Test results showed a significant effect of using a cricket bat on improving kasti ball hitting ability, with t = –2.986, df = 29, and p = 0.006 (p < 0.05). This improvement indicates that modified teaching aids can help students improve strength, accuracy, and movement coordination when hitting the ball; nevertheless, the limited sample size and duration of the treatment are important notes, so future studies are recommended to involve a control group and a broader participant scope to strengthen the gen.
