Abstract

The sickle kick is one of the most frequently used techniques in pencak silat competitions and yields high scores, making kick speed a critical performance factor. A faster sickle kick is more difficult for opponents to anticipate, parry, or counter. Several physical components support effective sickle kick performance, including strength, flexibility, power, balance, and agility. This study specifically examined the contribution of leg muscle explosive power and balance to sickle kick speed. This research employed a correlational design involving 30 male athletes from the Pencak Silat Student Activity Unit of Universitas Negeri Yogyakarta (UNY), aged 19–23 years. Data were collected through tests and measurements, using the standing broad jump test to assess leg muscle explosive power, the standing stork test to measure balance, and a 10-second sickle kick speed test to evaluate kick performance. Data analysis was conducted using regression analysis to determine the contribution of each variable. The results revealed that leg muscle explosive power contributed 53.1% to sickle kick speed, while balance contributed 45.7%. When analyzed simultaneously, both variables accounted for 53.6% of the variance in sickle kick speed. These findings highlight the importance of developing leg muscle explosive power and balance within structured training programs to enhance sickle kick speed and overall competitive performance in pencak silat athletes.

Abstract

This study aims to compare the effectiveness of two service techniques, namely flat serve and spin serve, on direct point acquisition in a simulated tennis match situation. The subjects of the study consisted of 20 male junior tennis players, aged 14–16 years, who were divided into two groups based on service technique. Each group was to use one type of serve consistently during three sets of simulated matches. The variables observed included the number of direct points, service speed, accuracy, rally length, and number of double faults. The results of the independent t-test analysis showed that the flat serve group scored a higher average direct points mean, 9.2; SD = 2.15, than the spin serve group mean, 6.8; SD 1.69, with a t-value = 2.74; p = 0.013. Supporting analysis also showed that the flat serve had higher speed, while the spin serve was superior in accuracy and rally duration. These findings indicate that the flat serve is more effective for a fast point scoring strategy, while the spin serve is more suitable for long rallies and game control. Therefore, coaches are advised to integrate service variation training as part of the development of athletes’ playing strategies.

Abstract

Innovation in sports learning is increasingly important to enhance athlete performance through advanced technologies and personalized training methods. Research in this area explores effective strategies to integrate technology for optimized sports education. This study aims to investigate the role and impact of technology-based innovations in sports learning to improve athlete performance. The study employed a library research approach, which involves systematically collecting and analyzing existing literature, journals, and academic sources related to sports learning innovation. Library research enables a comprehensive review of current knowledge and trends without new experimental data collection. Findings indicate that technological tools such as video analysis to virtual reality, artificial intelligence, and mobile applications significantly enhance athletes learning experiences and performance outcomes by enabling personalized and accessible training. The integration of technology also fosters interactive and immersive learning environments supporting better skill acquisition and motivation. The study highlights the necessity of adopting innovative technological methods in sports education to meet athletes individual needs and improve training effectiveness. It also emphasizes library research as a critical method to synthesize existing knowledge for advancing sports learning innovation. However, challenges such as the availability and accessibility of technology and complex data management still need to be addressed. Thus, technology will continue to drive progress in sports training and help athletes and coaches in the future.
