Abstract

Volleyball is a game that is played continuously with short durations and high intensity, interspersed with brief recovery periods that occur sequentially during the match. The characteristics of the volleyball game require high endurance, making aerobic endurance training essential for the sustainability of athletes in developing their abilities, skills, and bodily endurance in order to adapt to the game which is played continuously with high intensity. This study aims to determine the effect of circuit training methods on the improvement of aerobic endurance. The method used is an experiment with a one-group pre-test and post-test design, with a sample size of 20 students aged 10-12 years who are active in the volleyball extracurricular at Limbangan Tengah 2 Elementary School. The research results show that there is a significant effect of circuit training methods on improving aerobic endurance in volleyball players aged 10-12 years. This is indicated by the average pretest score of 25.9850 and a posttest score of 42.8000, with a significance value of 0.000 < 0.005. Thus it can be concluded that there is a significant difference between the results of training with the circuit training method on the pretest and posttest data. Therefore, the circuit training method is very effective in improving aerobic endurance, which combines strength and endurance training by completing one group or circuit of exercises with minimal or no rest.

Abstract

This study aims to determine the effect of quickness and flexibility training on increasing the reaction time of sickle kicks in pencak silat athletes. This study uses a quantitative approach with a one-group pretest-posttest quasi-experimental design. The subjects of the study were 16 pencak silat athletes from Banjaran Silat Club, Bandung Regency. Treatment was given through a quickness and flexibility training program for 12 sessions. The measurement instrument used a hit sensor kick shield pad connected to a digital application to measure the reaction time of sickle kicks. The results of statistical analysis showed that the data were normally distributed (p > 0.05) based on the Shapiro-Wilk test. The Paired Sample t-Test showed a significant difference between the pre-test and post-test values (t = 12.591, p = 0.000). The average reaction time value decreased from 0.58669 seconds to 0.49288 seconds after treatment. These findings indicate that the combination of quickness and flexibility training is effective in increasing the reaction time of sickle kicks. This research contributes to the development of a pencak silat training program based on neuromotor and body flexibility.

Abstract

This study aims to determine the effect of interval training and continuous running on increasing the aerobic capacity of adolescent football athletes and to compare the effectiveness of the two methods. This study used an experimental method with a two-group pretest–posttest design. The sample consisted of 30 extracurricular youth football athletes from Subang Senior High School 2, selected using a total sampling technique. The instrument used to measure aerobic capacity was the Yo-Yo Intermittent Recovery Test Level 1 (YYIR1). Data were analyzed using statistical tests through the SPSS application, including normality tests, homogeneity tests, paired sample t-tests, and independent sample t-tests. Data analysis was carried out through normality tests, homogeneity tests, paired sample t-tests, and independent sample t-tests to determine differences in effects between groups. The results of the study showed, 1) Interval training is effective in increasing VO2max in soccer athletes. 2) Continuous running is also effective in increasing cardiovascular endurance, and 3) There is a substantial difference in the effects between the two methods, with interval training showing greater improvements than continuous running.
