Abstract

Physical fitness is a determining factor for human growth and development. From the age of 6 years to 18 years the process of growth and development is very rapid. The purpose of this study was to see how the growth and development of students aged 10-12 years or phase c using the TKSI test with 5 items tested. This type of research uses comparative descriptive research which involves collecting data from two or more different groups to understand the differences between them. The subjects of this study were 3 elementary schools based on geographical location. The research instrument used was the Indonesian student fitness test (TKSI) with test items Shuttle Shuttle Run 4x10 m Get ball, 600m Run, Child Ball, Tok Tok Ball and 30 seconds Baring Sitting. The test used One Way ANOVA and test norms that already exist in the Indonesian student fitness test book (TKSI). Data were processed using IBM SPSS 24 and Microsoft excel. This study shows the average physical fitness of students at SDN 19 Air Tawar Barat (16.31), SDN 08 Surau Gadang (17.55), and SDN 13 Batu Gadang (18.25). There was a significant difference in the level of physical fitness between the three schools. In conclusion, the physical fitness level of students at SDN 13 Batu Gadang is better than that of SDN 08 Surau Gadang and SDN 19 Air Tawar Barat, with a difference of 1.94 and 0.7 respectively.

Abstract

This study aims to evaluate the improvement of the character of karate extracurricular participants through the implementation of karate values in the activity, as well as to compare differences in children's character before and after participating in training for 3 months. The research method used is qualitative with data collection through interviews, observation, and documentation, and the validity of the data is tested by triangulation. The results showed that the application of karate values was successful in shaping the character of extracurricular participants. Training ceremonies, discipline, and playtime activities are well integrated, making the child happy and not bored. Karate vows also have a positive impact, such as increased personality, honesty, fighting power, ethics, and self-control. The implementation of the first karate vow succeeded in improving the child's personality by increasing social interaction and mutual respect. Although character still needs to be improved, character education through karate helps parents in imparting positive values to children. The second karate vow, which emphasizes honesty, is reflected in the child's courage to admit his mistakes. While the third to fifth karate vows, which emphasize achievement, courtesy, and self-control, are also successfully applied and improve the child's character in a better direction. Thus, this study concluded that the implementation of karate values in extracurricular exercises is able to shape children's character, including aspects of personality, honesty, fighting power, ethics, and self-control.

Abstract

Topspin stroke accuracy is a critical determinant of performance in table tennis, as it enables players to control ball placement and gain tactical advantages during competition. Although previous studies have identified the importance of cognitive and physical factors in sport performance, limited research has simultaneously examined the contributions of concentration and flexibility to topspin stroke accuracy. Therefore, this study aimed to investigate the relationships between concentration, flexibility, and topspin stroke accuracy among table tennis players. A cross-sectional correlational design was employed involving 62 table tennis players aged 20–23 years. Concentration was assessed using the Concentration Grid Test, flexibility using the Sit-and-Reach Test, and topspin accuracy using a standardized topspin accuracy test. Data were analyzed using Pearson correlation. The results revealed significant positive correlations between topspin accuracy and concentration (r=0.774, p<0.001) as well as flexibility (r=0.604, p<0.001). In conclusion, concentration and flexibility were significantly associated with topspin stroke accuracy, with concentration showing the strongest relationship. These findings suggest that both psychological and physical factors should be considered in training programs aimed at improving topspin performance in table tennis players.

Abstract

This study aims to analyze the differences in the effects of set system and circuit system weight training on the increase in arm muscle strength of rowing athletes in Agam Regency. This study is an experimental study using a two-group pretest-posttest design, in which 12 rowing athletes were divided into two different treatment groups using purposive sampling techniques. The research instrument used a 1-minute pull-up test based on the Indonesian Physical Fitness Test (TKJI) to measure arm muscle strength. Data analysis was performed using a paired sample t-test at a significance level of α = 0.05 to determine the difference in ability before (pre-test) and after (post-test) treatment. The results showed that (1) the set system weight training significantly increased arm muscle strength (t-count 25.30 > t-table 2.02), (2) circuit training also had a significant effect on increasing arm muscle strength (t-count 10.83 > t-table 2.02), and (3) there was no significant difference in effect between the two training methods (t-count 1.19 < t-table 2.02).

Abstract

This study aimed to determine the contribution of arm muscle strength to badminton smash accuracy among students participating in the badminton extracurricular program at SMAN 1 Lintau Buo. A quantitative correlational design was employed involving 10 students selected through total sampling. Arm muscle strength was measured using a 60-second push-up test, while smash accuracy was assessed using a badminton smash accuracy test. Data were analyzed using descriptive statistics, Pearson Product-Moment correlation, and the coefficient of determination at a significance level of 0.05. The results showed no significant relationship between arm muscle strength and smash accuracy (r = 0.058, p = 0.874), with a contribution of only 0.34%. These findings suggest that smash accuracy is influenced more by technical proficiency, coordination, movement timing, and biomechanical factors than by arm muscle strength alone. Therefore, integrated training programs are recommended to improve badminton smash performance.
