The Effect of Knee Brace and Armband Use on Motoric Performance in Volleyball: From Body Protection to Performance in the Context of the Skills Framework

This study aims to investigate the effects of knee pad and arm sleeve use on the motor performance of female volleyball players competing in school league categories. The study employed a pretest-posttest experimental design and included 133 voluntary athletes. Participants’ motor performance values, such as flexibility, balance, vertical jump, speed, agility, and aerobic endurance, were measured before and after the use of knee pads and arm sleeves. The results showed that the use of knee pads and arm sleeves led to statistically significant decreases in motor performance variables, particularly those evaluated within the scope of field skills (p < 0.05), including flexibility, balance, speed, agility, and aerobic endurance. These findings suggest that protective equipment may limit athletes' motor skills and highlight the importance of raising awareness regarding equipment selection and usage among athletes. Furthermore, the study contributes to understanding the relationship between the athlete’s game and technical knowledge and equipment use within the framework of conceptual skills and sheds light on the development of ergonomic designs. In this regard, the study is important for better understanding the impact of knee pads and arm sleeves used in volleyball on performance and for offering a holistic approach to athlete development.
