Abstract

This study aims to analyze the effect of repetitive front kick exercises on the balance and agility of Pencak Silat athletes from Persaudaraan Setia Hati Terate (PSHT), Rayon Mantup. The research employed a quantitative experimental method with a one-group pretest-posttest design. A sample of 28 athletes was selected using purposive sampling technique. Measurement instruments included the Standing Stork Test for balance and the T-Test TPS for agility. Data were analyzed using normality tests, homogeneity tests, and paired t-tests. The results of normality and homogeneity tests indicated that the data were normally distributed and homogeneous. The t-test yielded a significance value of 0.000 for both variables, which is less than 0.05, leading to the acceptance of the research hypothesis. The findings demonstrate that repetitive front kick training significantly improves both balance (t_calc = -9.686) and agility (t_calc = 11.180) of the athletes. This improvement is attributed to the characteristics of fast and repetitive movements that train body control and neuromuscular coordination. The study recommends integrating repetitive kick exercises into PSHT training programs to optimize athlete performance.

Abstract

Training is a planned and systematic process aimed at gradually and continuously improving the physical, technical, tactical, and mental abilities of athletes. One of the physical components that plays a significant role in football is the explosive power of the arm muscles, particularly in executing throw-in techniques. A strong and well-directed throw-in can provide a tactical advantage for the team. One exercise method believed to be effective in enhancing arm muscle power is training using medicine balls. This study aims to determine the effect of throwing exercises with medicine balls on the throw-in power of U-15 football players at SSB Untag Rosita Sidoarjo. The research employed a pre-experimental method using a One Group Pretest–Posttest Design. The study population consisted of 15 U-15 football players from SSB Untag Rosita Sidoarjo, with samples selected through total sampling. The data collection instrument used was the throw-in distance test, measured before and after the training intervention. Data were analyzed using the Paired Sample t-test with a significance level of 0.05.The results showed an increase in the average throw-in distance after the training using medicine balls. Based on the results of the Paired Sample t-test, a significance value (p-value) < 0.05 was obtained, leading to the rejection of H? and the acceptance of H?. Thus, it can be concluded that throwing exercises using medicine balls have a significant effect on improving the throw-in power of U-15 football players at SSB Untag Rosita Sidoarjo.

Abstract

This research is motivated by the low 100-meter sprint speed of seventh-grade students at SMP Negeri 1 Sedati and the lack of variation in training methods provided. The objective of this study is to determine the significant effect of implementing the interval training method on improving students' 100-meter sprint speed. This study adopts a quantitative approach with a quasi-experimental method using a Pretest-Posttest Control Group Design. The research population consisted of all seventh-grade students at SMP Negeri 1 Sedati, with a sample of 30 students selected through a purposive sampling technique. The instrument used was a 100-meter sprint test to measure student speed before and after the treatment. Data analysis was conducted using the Independent Samples T-Test facilitated by SPSS software. The results showed a significant difference between the experimental group and the control group. Based on the statistical analysis, a significance value (2-tailed) of 0.000 was obtained, which is lower than the 0.05 significance level (0.000<0.05 0.000<0.05). The average speed improvement in the experimental group was significantly higher than in the control group, which received conventional instruction. In conclusion, the interval training method has a significant positive influence on increasing 100-meter sprint speed. This study suggests that physical education teachers should implement interval training as an effective variation to enhance students' athletic abilities.

Abstract

This research is motivated by the importance of developing gross motor skills in children with mild intellectual disabilities through adaptive physical education that is engaging and appropriate to students’ characteristics. Based on preliminary observations at Budhi Special School in Surabaya, students’ gross motor skills, particularly running ability, were still relatively low because learning activities tended to use simple and less varied movement exercises. As a result, students easily became bored and lacked motivation to participate actively in physical activities. Therefore, traditional games such as gobak sodor can be used as an alternative learning medium that is more enjoyable and capable of stimulating students’ physical movement. This study aims to analyze the effect of the gobak sodor traditional game on improving gross motor skills, especially running ability, in children with mild intellectual disabilities. The research employed a quantitative approach using a quasi-experimental method with a one-group pretest–posttest design. The sample consisted of 20 students selected through purposive sampling. The research instrument used was a 40-meter sprint test to measure students’ gross motor skills. Data were analyzed using descriptive statistics and a paired sample t-test with the assistance of SPSS version 23 software. The results showed a significant difference between the pretest and posttest results with a significance value of 0.032 (<0.05), indicating that the gobak sodor game has a significant effect on improving students’ gross motor skills. Thus, the gobak sodor traditional game is effective as a learning method to enhance the gross motor skills of children with mild intellectual disabilities.
