Abstract

This study aimed to examine the impact of interval training on 30-meters sprint speed in elementary school children. This study emphasized the importance of appropriate training methodology to improve students' physical fitness, particularly in speed ability. This study used a quantitative methodology with a quasi-experimental design featuring a pretest-posttest control group. The study sample consisted of 54 sixth-grade students divided into an experimental group and a control group. The experimental group underwent interval training for four weeks, while the control group followed traditional physical education instruction. Data collection was conducted by assessing the 30-meters sprint. Data analysis used descriptive statistics and non-parametric testing, specifically the Wilcoxon and Mann–Whitney tests. The results showed a significant increase in the experimental group from pretest to posttest. However, there was no significant difference between the experimental and control groups in the posttest results. These findings indicate that interval training can improve sprint speed, but has not shown significant benefits compared to traditional techniques. The uniqueness of this study lies in the implementation of interval training in the elementary school physical education curriculum, using a controlled experimental methodology. Although interval training improved sprint performance within the experimental group, it did not produce significantly greater improvements compared to traditional physical education methods

Abstract

This study aims to determine the effect of circuit training on freestyle swimming leg speed in athletes aged 8–12 years. Foot speed is one of the important factors that affect swimming performance, so effective training methods are needed to improve it. This study used an experimental method with a pretest-posttest control group design. The study sample amounted to 30 athletes who were divided into experimental groups and control groups. The experimental group was given treatment in the form of circuit training exercises, while the control group underwent routine exercises. Data collection was carried out using a freestyle leg speed test of 25 meters measured in units of time (seconds). The results showed that both groups experienced improvement, but the improvement in the experimental group was higher than in the control group. The average time in the experimental group decreased from 39.53 seconds to 32.33 seconds, while in the control group decreased from 41.00 seconds to 39.47 seconds. The results of statistical analysis showed a significant difference between the two groups. These findings show that circuit training is  more effective than regular exercise in increasing freestyle leg speed. The novelty of this study lies in the application  of circuit training as a structured ground training method to increase foot speed in early age athletes. This study provides empirical evidence on the effectiveness of dryland circuit training in enhancing lower-limb propulsion performance in young swimmers.

Abstract

This study was motivated by the low passing ability, particularly in the spin pass technique, among university rugby athletes, as indicated by poor directional accuracy, inadequate throwing power, and limited ball control. Therefore, this study aimed to examine the effect of a target-based spin pass training model on passing accuracy in rugby. The study employed a quantitative approach using a quasi-experimental one-group pretest–posttest design. The participants consisted of 14 university rugby athletes selected through purposive sampling. The intervention was conducted over 12 training sessions using a target-based spin pass training program. Passing accuracy was measured using a fixed-target spin pass test with established validity. Data were analyzed using descriptive statistics, normality testing, paired sample t-tests, and effect size analysis. The findings revealed a significant improvement in passing accuracy, with the mean score increasing from 9.63 in the pretest to 12.39 in the posttest. The paired sample t-test showed a significant difference between pretest and posttest scores (t = -4.911, p < 0.05). In addition, the effect size indicated a strong practical impact of the intervention on passing performance. These findings suggest that the target-based spin pass training model is effective in improving rugby passing accuracy and can be recommended as an innovative and structured training method for university rugby athletes.

Abstract

This study aims to determine the relationship between leg muscle power and long kick distance in soccer players of SSB Aroffa. A quantitative correlational design was employed with 30 athletes as the sample. The instruments used were the vertical jump test and long kick test. Data were analyzed using Pearson correlation. The results showed a correlation coefficient of 0.188 with a significance value of 0.320 (>0.05), indicating no significant relationship between the variables. It can be concluded that long kick distance is not only influenced by leg muscle power but also by other factors such as technique and coordination. Keywords: Leg Muscle Power, Soccer, Long Kick

Abstract

This study was motivated by the increasing use of true wireless stereo (TWS) devices among university students while jogging, which potentially increases ear health and safety risks. Previous studies have addressed the impact of audio devices on physical performance. Physical education students differ from the general student population due to their higher intensity of physical activity, including regular jogging as part of their academic routine and lifestyle. This leads them to use TWS devices more frequently and for longer durations, especially during dynamic physical activities. This study used a qualitative case study approach with 15 participants, including 13 university students and 2 ENT specialists, for source triangulation. Data collection techniques included observation, interviews, and documentation, with data analysis using NVivo 12 software and participant data collection using a purposive sampling technique. The results showed that most university students used TWS devices for more than 60 minutes and at volume levels above 60%, both during jogging and other activities. While this use has positive effects, such as increased motivation, reduced fatigue, and greater comfort during exercise, negative effects have also been reported, including tinnitus (ringing in the ears), pain, dizziness, and decreased awareness of the surrounding environment, which can increase the risk of accidents. Source triangulation with an ENT doctor increases the risk of hearing loss from prolonged exposure to excessive noise. Therefore, education and awareness are needed to implement safe TWS use and maintain ear health.

Abstract

This study aims to test a focused training method, namely with a rope barrier to improve the accuracy of T kicks and student safety in beginner pencak silat training. This study was driven by two common problems in beginner training, first is poor kick accuracy and second is that rigid training equipment can also cause injuries. The data of this study used a quantitative research approach with a quasi-experimental non-equivalent control group design. A total of 111 students from 18 dynamic physics classes participated in this study, with 57 of them as the experimental group and the remaining 54 students as the control group. The experimental group trained with ropes, while the control group trained with chair-based media. Data were analyzed using the Wilcoxon Signed Rank Test and the Mann–Whitney U Test. Results In both groups, the pre-test showed a significant increase after participating in this training session (experimental group: p < 0.001; control group: p < 0.001). However, the difference between groups was not significant (p = 0.994) which means that both training methods improved the accuracy of T kicks in steady state to a similar value. Regardless, rope barriers serve as a safer and more versatile training environment by minimizing impact compared to rigid chairs. Conclusion Rope barriers are a simple, inexpensive, and safe alternative for basic pencak silat training at the elementary level.
