This study outlines the assessment of the cyber–physical system SPERTA, which was designed to evaluate the real-time performance of Taekwondo athletes. The system conducts performance analyses focusing on speed, acceleration, strength, and identifying and quantifying the athlete’s movements. The research involved administering an online questionnaire to athletes and coaches to evaluate the system’s acceptance and usability. The methodology included using a questionnaire with open and closed questions to assess participant satisfaction and system usability. The results showed a positive response to the system, with participants emphasizing its reliability and ease of use. An analysis of the responses revealed a strong internal consistency, as indicated by the Cronbach’s alpha coefficient, which enhances the research instrument’s reliability. Additionally, the analysis of open-ended questions was conducted through thematic analysis to gain a deeper understanding of participants’ experiences and perceptions of the system. These results highlight the effectiveness of the SPERTA system as a valuable tool for the real-time performance evaluation of Taekwondo athletes, providing insights for future improvements and the development of more effective training techniques.
