Abstract

The basic squat exercise is a strength exercise that is widely used to strengthen the muscles of the lower body, including the quadriceps, hamstrings and glutes. However, improper technique in performing squats can increase the risk of injury. This article aims to analyze the biomechanics of movements in squat training, with a focus on how correct technique can influence exercise efficiency and injury risk. This study used one subject as a sample to evaluate body posture and joint movement angles during exercise. The measuring instrument used is a goniometer to measure the angles of the knee and hip joints in various squat positions. Research results show that correct squat technique, with appropriate joint angles, not only increases exercise efficiency but also reduces the risk of injury. Conversely, incorrect technique can cause excessive stress on the knee and hip joints. These findings emphasize the importance of correct technique training in squat exercises to achieve maximum benefits and reduce the potential for injury.

Abstract

This study focuses on the physical condition profile of athletes at the Kancil Mas Football School (SSB) U-15 category, to evaluate the level of physical fitness of athletes in supporting their optimal performance on the field. The physical conditions measured include endurance, speed, agility, and leg muscle explosive power, which are key elements in the game of football. This study uses a quantitative descriptive method, with instruments in the form of physical tests such as the Bleep Test, 30-meter run, shuttle run, and standing long jump. The results showed that most athletes had adequate physical condition, with the majority of athletes in the "Good" category for speed and explosive power, and the "Fair" category for endurance and agility. However, aerobic endurance and agility still require more attention to achieve a higher level of performance. This study provides important insights for coaches and training program managers at SSB Kancil Mas to design more targeted development strategies. These findings also emphasize the importance of continuous evaluation to ensure athlete readiness in facing competition. Through a data-based approach, this research is expected to be the basis for effective decision-making in improving the quality of coaching for young athletes at SSB Kancil Mas.

Abstract

This study investigates the biomechanics of Stephen Curry's shooting technique, focusing on the factors contributing to his unparalleled accuracy in basketball, particularly for long-range shots. Using a quantitative descriptive approach, biomechanical analysis was performed by examining kinematic and kinetic parameters derived from video recordings of NBA games. Key body mechanics, including the coordination of the lower body for propulsion and the upper body for precision, were analyzed using motion capture systems and software like Kinovea. The findings reveal that optimal joint angles are critical for shot success: a knee angle of approximately 45 degrees during the propulsion phase and an elbow angle of 90 degrees at shot release. The study highlights that a ball trajectory with an elevation angle of 45-50 degrees significantly enhances scoring potential. Moreover, the speed of the ball at release, averaging 30-35 mph for three-pointers, plays a crucial role in shot stability and accuracy. The research emphasizes the importance of biomechanical principles, such as the efficient transfer of kinetic energy from the lower to the upper body, precise wrist rotation, and ideal trajectory, in improving shooting performance. These insights underline the need for basketball coaches and players to adopt training techniques informed by biomechanical data. Enhancing body positioning, lower body strength, and ball control are essential for developing more effective shooting skills. The study concludes that mastering biomechanical principles provides a significant edge in professional basketball performance, offering valuable perspectives for athletes and trainers alike.
