Description
Abstract
The study aimed to investigate the relationship between applied force, body mass, and acceleration in sports, with the goal of improving athletic performance and reducing injury risks. The research was conducted at the Thai Nguyen University of Education, involving 35 Physical Education students who participated in movement tests such as vertical jumps, long jumps, and sprints. Data were collected on force, body mass, and velocity using force plates, high-precision scales, and speed sensors. The analysis revealed that an increase in push-off force significantly enhanced acceleration and velocity, while body mass influenced the amount of force required to achieve optimal performance. For example, in high jump, an optimal push-off angle between 120–130 degrees led to higher jump heights, and in sprinting, a stable forward-leaning posture improved acceleration. The study also highlighted the importance of optimizing technique, such as adjusting foot push-off angles and body posture. The integration of modern technology like Kinovea software for motion analysis provided valuable insights into movement efficiency and technique refinement. The findings indicate that applying Newton’s laws in sports can lead to significant improvements in force generation, acceleration, and overall performance. Additionally, biomechanical analysis tools enable personalized training strategies that optimize results and minimize injury risks.
