The system conducts performance analyses focusing on speed, acceleration, strength, and identifying and quantifying the athlete\u2019s movements. The research involved administering an online questionnaire to athletes and coaches to evaluate the system\u2019s 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\u2019s alpha coefficient, which enhances the research instrument\u2019s reliability. Additionally, the analysis of open-ended questions was conducted through thematic analysis to gain a deeper understanding of participants\u2019 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.<\/jats:p>","DOI":"10.3390\/app14114683","type":"journal-article","created":{"date-parts":[[2024,5,30]],"date-time":"2024-05-30T08:15:54Z","timestamp":1717056954000},"page":"4683","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["User Assessment of a Customized Taekwondo Athlete Performance Cyber\u2013Physical System"],"prefix":"10.3390","volume":"14","author":[{"given":"Pedro","family":"Cunha","sequence":"first","affiliation":[{"name":"Algoritmi Research Centre, University of Minho, 4800-058 Guimaraes, Portugal"},{"name":"2Ai\u2014School of Technology, IPCA, Vila Fresca\u00ednha S.
