Abstract

This study aims to analyze pacing strategies, the influence of the start reaction, and performance consistency of male athletes in sprint freestyle swimming events (50m and 100m) at the 2025 SEA Games. The research used a descriptive quantitative approach with a case study design. Secondary data were analyzed from the finals of both events, including final times, reaction times (RT), and split times. Descriptive and comparative statistical analyses were conducted to evaluate pacing patterns, the relationship between RT and final results, and the performance of athletes competing in both events. All athletes in the 100m event applied a positive split pattern, with an average speed decrease of 2.26 seconds in the second half. The start reaction did not significantly correlate with the final time in the 50m (r=0.15; p=0.71) or the 100m (r=0.45; p=0.26). Athletes competing in both events showed high ranking consistency. The age group <20 years tended to have a smaller pacing difference (2.16 seconds) compared to older athletes. Pacing strategies at the regional level are still dominated by the conventional approach (positive split). The main determinant of performance is not the start reaction, but pure swimming speed and technical efficiency.

Abstract

Background: Enhancing basketball player performance requires a clear understanding of effective movement techniques. This study aims to synthesize and analyze key biomechanical techniques that influence performance, based on a systematic review of recent research. Methods: Following PRISMA guidelines for systematic reviews and meta-analyses, a comprehensive literature search was conducted using the Scopus database. The search targeted studies published between January 2020 and December 2024 using the keywords “basketball” and “biomechanics.” After three stages of screening based on predefined inclusion and eligibility criteria, 13 articles were selected from an initial pool of 231 for in-depth analysis. Results: The selected studies provided comprehensive insights into the biomechanical variables affecting basketball performance. Participants included both male and female athletes, with some studies emphasizing external conditions such as fatigue as injury risk factors. Key biomechanical factors identified include knee inversion and rotational moments, ground reaction forces, ankle stability, lower-limb characteristics, midsole hardness, joint loading during landing, core activation and stability, joint angles, knee flexion velocity, dynamic balance, directional changes, and shoulder positioning. Conclusion: Player performance in basketball is influenced by multiple biomechanical elements, including movement efficiency, joint stability, muscular strength, and technical execution. External factors such as fatigue and footwear characteristics also play a significant role in injury prevention and performance optimization. These findings support the need for targeted, biomechanically informed training interventions in basketball.

Abstract

Background: Kabaddi is a physically demanding contact sport that exposes youth athletes to high biomechanical stress, often resulting in injury. While positional roles in Kabaddi differ in movement patterns and physical demands, their association with injury prevalence among adolescent players remains underexplored. Objectives: This study aimed to investigate the prevalence and distribution of musculoskeletal injuries among youth Kabaddi players in Indonesia and to examine whether playing position, age, and experience contribute to injury risk. Methods: A cross-sectional survey was conducted involving 161 youth Kabaddi players aged 11–18 years across five regions. Injury data from the past 12 months and past 7 days were collected using a modified Oslo Sports Trauma Research Centre (OSTRC) questionnaire. Descriptive statistics and one-way ANOVA were performed to analyse differences in injury patterns based on player demographics and positions (All-rounder, Defender, Raider). Results: The most commonly injured regions were the shoulders, neck, and back, with no statistically significant differences in injury prevalence across playing positions (p > 0.05). However, older athletes (15–18 years) showed a significantly higher number of injuries compared to younger players (p < 0.05). Raiders reported the highest mean playing experience, while all-rounders were the oldest group. Despite biomechanical differences between roles, injury patterns appeared to be uniformly distributed. Conclusions: Injury prevalence among youth Kabaddi players is high and not confined to specific playing positions. This indicates that sport-wide preventive strategies, emphasizing core stability, neuromuscular control, and fatigue management, may be more effective than role-specific interventions. Findings reinforce the importance of biomechanical screening and integrated injury surveillance in youth Kabaddi development programs.

Abstract

Penelitian ini bertujuan untuk menganalisis efisiensi fisik dan performa atlet sepakbola pelajar pada pertandingan Asia Footbal Federation (AFF) U-17 tahun berdasarkan posisi dalam permainan Sepakbola. Pendekatan latihan yang masih mengutamakan fisik dalam bermain menjadi alasan untuk melihat efisiensi penggunaan kapasitas fisik dalam meningkatkan performa atlet pelajar di dalam pertandingan. Metode yang digunakan dalam penelitian ini adalah analisis kuantitatif dengan subjek penelitian berjumlah 20 Atlet Sepakbola Pelajar yang tergabung dalam timnas Sepakbola Indonesia U-17 Tahun. Proses pengumpulan Data menggunakan GPS tracker dan heart rate monitor, kemudian dihitung rasio efisiensi antara lain Beban Atlet (Player Load/meter), Heart rate/Meters) dan nilai efisiensi performa atlet pelajar. Analisis dilakukan menggunakan uji Kruskal-Wallis dan korelasi Pearson. Hasil dari penelitian ini menunjukkan pertama, tidak terdapat perbedaan signifikan dalam penggunaan kapasitas fisik dengan performa atlet pelar di pertandingan, kedua yaitu terdapat korelasi yang sangat kuat antara jarak berlari dengan beban atlet/PlayerLoad (r = 0.8115), Ketiga jarak berlari atlet memiliki hubungan korelasi yang lemah dengan Denyut Nadi Pemain (Heart rate/Meter) dalam peningkatan performa permainan. Kesimpulan dalam penelitian ini adalah efisiensi penggunaan kemampuan fisik dalam bermain sepakbola khususnya timnas pelajar U-17 tahun ini di pengaruhi oleh karakter bermain individu bukan berdasarkan posisi bermain dalam pertandingan. Terlihat pada hasil penelitian efisiensi fisiologis dan mekanis dalam bermain tertinggi berasal dari 3 posisi yang berbeda. Penggunaan kemampuan fisik harus selaras dengan eksekusi teknik, pemahaman taktikal dan kemampua menghadapi tekanan disertai dengan pengambilan keputusan yang tepat dalam pertandingan.   Abstract:This study aims to analyze the physical efficiency and performance of student athletes in the U-17 Asia Football Federation (AFF) matches based on position in the football game. A training approach that still prioritizes physicality in playing is a reason to look at the efficient use of physical capacity in improving the performance of student athletes in competitions. The method used in this research is quantitative analysis with research subjects consisting of 20 football student athletes who are members of the U-17 Indonesian National Football Team. The data collection process uses a GPS tracker and heart rate monitor, then efficiency ratios are calculated including Athlete Load (Player Load/meters), Heart rate/Meters) and student athlete performance efficiency values. Analysis was carried out using the Kruskal-Wallis test and Pearson correlation. The results of this study show firstly, there is no significant difference in the use of physical capacity and the performance of athletes in competitions, secondly, there is a very strong correlation between running distance and athlete load/PlayerLoad (r = 0.8115). Thirdly, athlete running distance has a weak correlation with the Player's Heart Rate (Heart rate/Meter) in improving game performance. The conclusion in this research is that the efficiency of using physical abilities in playing football, especially for the U-17 student national team this year, is influenced by individual playing character, not based on playing position in the match. It can be seen from the research results that the highest physiological and mechanical efficiency in playing comes from 3 different positions. The use of physical abilities must be in harmony with technical execution, tactical understanding and the ability to deal with pressure accompanied by making the right decisions in the match.
