Engineering ergonomic risk assessment of karate choku zuki straight punch

Abstract

This study utilizes the Rapid Upper Limb Assessment (RULA) technique to evaluate suggested improvements aimed at enhancing the safety and efficacy of the Choku Zuki (Straight Punch), a high-risk karate exercise. The primary objective is to identify and address potential musculoskeletal issues associated with this technique. Given the prevalence of musculoskeletal injuries in sports, particularly in activities with high intensity like karate, the need for reliable ergonomic risk assessment tools such as RULA is paramount. By applying RULA to analyze the ergonomic aspects of the Choku Zuki punch, this study provides crucial insights into potential areas of concern. It identifies specific postures and movements that may predispose practitioners to injury, allowing for the development of targeted interventions to mitigate risks and enhance safety. Furthermore, this research underscores the importance of integrating ergonomic considerations into sports training regimens to optimize performance and minimize injury risks. Beyond its implications for karate training, the study emphasizes the broader significance of ergonomic assessments in sports science and engineering. It showcases how engineering methodologies can be leveraged to improve the safety, efficiency, and overall performance of sporting activities, fostering collaboration between sports scientists, engineers, athletes, coaches, and healthcare professionals to advance sports performance and safety standards.lities.
