Abstract

Kelelahan otot lower body secara langsung memengaruhi efisiensi gerakan take off dalam jump spike. Hubungan antara kelelahan dan perubahan kinematika ini menjadi faktor krusial dalam menentukan performa optimal atlet bola voli. Penelitian ini bertujuan untuk menganalisis pengaruh kelelahan otot lower body terhadap kinematika pada fase take off teknik jump spike serta hubungan antara pusat gravitasi tubuh (CG) dan gaya reaksi tanah (GRF). Sampel sebanyak 12 atlet laki-laki Unit Kegiatan Mahasiswa (UKM) Bola Voli Universitas Pendidikan Indonesia (UPI) Bandung. Penelitian ini menggunakan metode deskriptif dengan pendekatan kuantitatif menggunakan desain pretest dan posttest. Teknik analisis data yang digunakan adalah Uji Paired T Test. Hasil penelitian menunjukkan peningkatan signifikan kadar asam laktat, yang mengindikasikan akumulasi akibat kelelahan. Pada parameter kinematika, tidak ditemukan perbedaan signifikan pada sudut ankle, knee, dan hip, meskipun terjadi perubahan. Namun, jump height menunjukkan penurunan signifikan, menunjukkan bahwa kelelahan mempengaruhi kemampuan lompatan. Selain itu, tidak ditemukan hubungan signifikan antara kelelahan dan perubahan parameter kinematika lainnya. Penelitian ini menyimpulkan bahwa kelelahan otot lower body berdampak signifikan pada performa jump height, namun tidak mempengaruhi sudut tubuh selama fase take off teknik jump spike. Penelitian ini menyarankan pentingnya pengelolaan kelelahan otot untuk menjaga performa jump spike. Pelatih dan atlet harus fokus pada pemulihan dan penguatan lower body. Implikasi penelitian menunjukkan bahwa meskipun sudut tubuh tidak terpengaruh, penurunan jump height dapat mengurangi efektivitas permainan, sehingga latihan daya tahan dan teknik lompatan perlu ditingkatkan.

Abstract

Speed ​​is one of the important aspects of physical condition in athletics, especially those involving fast movements such as soccer. This study aims to determine the effectiveness of the Small Side Games training method in increasing speed in soccer players aged 17-18 years. The research method used is an experimental design with a pre-experimental approach (pre-test, post-test design), where speed measurements were taken before and after treatment. The subjects of the study consisted of 30 Persib Bandung Academy athletes who participated in training for 5 weeks with a total of 15 meetings. Training was given three times a week with the application of the progressive overload principle, namely increasing training volume through training duration. The results of the study showed that the application of Small Side Games training did not provide significant changes in increasing speed in soccer athletes aged 17-18 years. This finding provides an illustration that this training method may need further adjustment to increase its effectiveness in increasing speed.

Abstract

This study aims to analyze the effect of training with interval, pyramid, and mix methods in small sided game (SSG) on increasing 30-meter speed. This study uses a quantitative design with a pre-test and post-test approach to compare the three training methods. The research sample consisted of 30 male soccer athletes aged 17 to 18 years from the Persib Bandung Academy who followed a 6-week training program. Sampling was carried out using a simple random sampling technique. The data collected were analyzed using parametric statistics, after passing the normality, homogeneity, and paired sample t-test tests by showing results that met the requirements. The results showed that there was no significant difference between the interval, pyramid, and mix training groups in increasing 30-meter running speed.

Abstract

This study analyzes the effect of variations in Small-Sided Games (SSG) training methods on increasing anaerobic lactase capacity in U-17 soccer players by comparing the Pyramid and Interval methods. Using a quantitative pre-test and post-test experimental design, this study involved 20 players selected by purposive sampling, with anaerobic capacity measured through the Running-Based Anaerobic Sprint Test (RAST). The results of the Paired Sample T-Test showed that the Pyramid method significantly increased anaerobic lactase capacity, with a more significant decrease in Fatigue Index than the Interval method (p = 0.029, p < 0.05), indicating its effectiveness in maintaining explosive power and ATP-PCr regeneration. In contrast, the Interval method did not significantly increase (p = 0.598, p > 0.05). However, the Independent Sample T-Test results showed no significant difference between the two methods in increasing anaerobic capacity (p = 0.977). These findings suggest that both Pyramid and Interval methods can improve explosive power and ATP-PCr regeneration, with effectiveness that can be adjusted based on athlete needs and training strategies. In conclusion, the application of SSG as an effective and enjoyable training method, with further research involving larger samples, longer training durations, and additional analysis such as effect size to optimize training effectiveness.

Abstract

Hitting is a basic technique that must be mastered in softball. Efficient hitting requires good coordination between the lower limbs, core, and arms. This study aims to analyze the launch angle and exit velocity characteristics of the hitting technique between elite and amateur softball athletes. This study used a quantitative descriptive method. The population consisted of 13 athletes, including 5 elite athletes and 8 amateur athletes, who were selected using purposive sampling. Data collection used documentation techniques by recording the batting movements of the samples which then the video results will be analyzed using Kinovea and SkillSpector software, and the data was analyzed using SPSS version 26.0 with Independent Sample T-Test. The results showed significant differences in launch angle (p=0.025), exit velocity (p=0.004), and swing speed (p=0.015) between elite and amateur athletes. However, there were no differences in elbow angle (p=0.904) and elbow velocity (p=0.123). This study concludes that there are significant differences in batting technique characteristics between elite and amateur softball athletes, with elite athletes showing better performance in launch angle, exit velocity, and swing speed. However, both samples were similar in elbow and elbow angle velocity.

Abstract

This study aims to analyze the influence of physical condition quality on the performance of chess athletes with disabilities at the 2024 National Paralympic Games (PEPARNAS) in West Java. Employing a quantitative approach, the study involved 21 chess athletes competing in individual and team categories. Physical condition data were collected through the Sit and Reach test for flexibility and the Balke test for aerobic endurance, while performance was measured based on medal achievements. Linear regression analysis revealed that flexibility and aerobic capacity accounted for only 0.1% of the variation in individual performance (R² = 0.001, p = 0.991) and 5.9% of the variation in team performance (R² = 0.059, p = 0.576), indicating that these variables had no significant impact on chess performance. These findings confirm that chess relies more on cognitive and strategic abilities than physical condition.
