Abstract

This study aims to determine the effect of the speed play training method on increasing cardiovascular endurance (VO₂max) in pencak silat athletes of the single arts category. Using a pretest-posttest control group design, ten athletes were divided into experimental and control groups. The experimental group received a structured speed play training program for eight sessions, while the control group followed their regular training routines. The Beep Test was used as the primary instrument to estimate VO₂max. The results of the independent t-test showed a significant difference between the groups (p = 0.044), with an average VO₂max increase of 1.04 points in the experimental group. These findings suggest that speed play is effective in improving aerobic capacity, especially due to its varied intensity patterns that match the dynamic and uninterrupted demands of single arts performances. The study also provides evidence that speed play can serve as a specific training model for pencak silat art athletes and offers recommendations for further research involving more diverse participants and physiological indicators.

Abstract

This study aimed to investigate the effect of core stability exercises on the accuracy of jump serves in volleyball athletes. The research was conducted using a quasi-experimental design with a two-group pre-test and post-test approach. The participants consisted of volleyball athletes from the Star Sport Rancaekek Club, who were divided into an experimental group and a control group. The experimental group received a five-week core stability training program, while the control group continued their regular training routine. Jump serve accuracy was measured using the AAHPER Serving Accuracy Test. Data analysis showed that the experimental group demonstrated a significant improvement in serve accuracy compared to the control group. These findings indicate that core stability training effectively enhances body balance, postural control, and coordination—key components in executing accurate jump serves. The results highlight the importance of incorporating core stability exercises into volleyball training programs, especially for improving specific technical skills. This study contributes to the field of sports coaching by offering practical insights into effective methods for developing skill-based performance in young volleyball athletes.

Abstract

Aerobic capacity is a crucial component of an athlete’s performance, especially in team sports like futsal, which require high endurance. Short Interval Training (SIT) has been widely used to improve aerobic capacity; however, individualized approaches based on Maximum Aerobic Speed (MAS) remain limited. This study aims to investigate the effect of a SIT program based on high MAS on the aerobic capacity among female futsal athletes. An experimental method with a one-group pretest–posttest design was used, involving five athletes from the Student Activity Unit at Universitas Pendidikan Indonesia. Participants underwent 16 training sessions over 8 weeks, with intensities set at ≥95% of each athlete’s maximal effort. VO₂max was measured before and after the training program. Statistical analysis using a paired sample t-test showed a significant improvement in VO₂max from 39.39 to 40.73 ml/kg/min (p = 0.004, p < 0.05). This approach allows for better training precision and physiological adaptation by adjusting workloads according to each athlete’s aerobic threshold. These findings indicate that SIT program based on high MAS is effective in improving aerobic capacity and enhancing recovery during the match. The results support the implementation of SIT program based on high MAS as an efficient and personalized training strategy for athlete conditioning programs.

Abstract

This study aimed to investigate the impact of personalized interval training (short and long) based on Maximum Aerobic Rate (MAS) on improving athletes’ aerobic capacity. Using quantitative experimental method with 2x2 factorial design, 16 athletes were divided into four groups: SIT-MAS High, SIT-MAS Low, LIT-MAS High, and LIT-MAS Low. Although the Friedman test showed no statistically significant differences in aerobic improvements among the four groups overall, intra-group analysis showed mixed results. Statistically significant increases in aerobic capacity were found in the  LIT-MAS High and SIT-MAS low groups, which supported the third and fifth hypotheses. In contrast, the improvements in the SIT-MAS High and LIT-MAS Low groups were not significant. There was also a significant difference between SIT and LIT in the low MAS group, but not in the high MAS group. This study concludes that personalization of interval training based on an individual’s MAS profile is important, with LIT shown to be effective for low MAS athletes and SIT effective for high MAS athletes. Limitations of this study include the very small sample size (n=3 or n=4 per group), as well as external factors such as inconsistent training schedules, pressure from competition, and athlete injuries.

Abstract

This study aims to examine the effectiveness of the Long Interval Training (LIT) method adapted to high Maximum Aerobic Speed (MAS) capacity on increasing aerobic capacity. Aerobic capacity is the body’s ability to absorb and use oxygen during exercise and is closely related to VO₂max. This capacity is important for physical performance, especially in middle and long distance races. This study used an experimental method with a One Group Pretest-Posttest design through purposive sampling. The treatment was given for 16 training sessions, and the measurement test was carried out with the Balke Test before and after treatment (pre-test and posttest). Data were analyzed using Data Descriptive Analysis, Shapiro-Wilk normality test, and Paired Samples t-Test test. The results showed a significant increase in VO₂max value after treatment. The Paired Samples t-Test test shows a significance value (Sig. 2-tailed) of 0.018, which is smaller than 0.05, so there is a significant difference between the pre-test and post-test scores. This proves that the high MAS-based LIT method is effective in increasing aerobic capacity. This study emphasizes the importance of good training load management, close supervision, and proper recovery strategies. Therefore, although the LIT method was shown to be effective, safe and sustainable implementation should consider the athlete’s overall training load to prevent injury and fatigue.
