The lumbopelvic region is crucial for generating kinetic energy in pitching. Real-time biofeedback enhances training effectiveness and reduces injury risk. The validity and reliability of this system were examined. Purpose: This study was to investigate the validity and reliability of the real-time biofeedback system for lumbopelvic control training. Methods: Twelve baseball players participated in this study, with data collected in two sessions separated by a week. All participants needed to do the lateral slide exercise and single-leg squat exercise in each session. Pelvic angles detected by the real-time biofeedback system were compared to the three-dimensional motion capture system (VICON) during training sessions. Additionally, pelvic angles measured by the biofeedback system were compared between the two training sessions. Results: The real-time biofeedback system exhibited moderate to strong correlations with VICON in both exercises: lateral slide exercise (r = 0.66\u20130.88, p &lt; 0.05) and single-leg squat exercise (r = 0.70\u20130.85, p &lt; 0.05). Good to excellent reliability was observed between the first and second sessions for both exercises: lateral slide exercise (ICC = 0.76\u20130.97) and single-leg squat exercise (ICC = 0.79\u20130.90). Conclusions: The real-time biofeedback system for lumbopelvic control training, accurately providing the correct pelvic angle during training, could enhance training effectiveness.<\/jats:p>","DOI":"10.3390\/s24103060","type":"journal-article","created":{"date-parts":[[2024,5,13]],"date-time":"2024-05-13T11:18:17Z","timestamp":1715599097000},"page":"3060","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["The Validity and Reliability of a Real-Time Biofeedback System for Lumbopelvic Control Training in Baseball Players"],"prefix":"10.3390","volume":"24","author":[{"given":"Shiu-Min","family":"Wang","sequence":"first","affiliation":[{"name":"School and Graduate Institute of Physical Therapy, College of Medicine, National Taiwan University, No. 17, Xuzhou Rd., Zhongzheng Dist., Taipei City 100, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Po-Hsien","family":"Jiang","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, College of Engineering, National Taiwan University, No. 1, Sec. 4, Roosevelt Road, Taipei 106, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kuei-Yuan","family":"Chan","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, College of Engineering, National Taiwan University, No. 1, Sec. 4, Roosevelt Road, Taipei 106, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4577-140X","authenticated-orcid":false,"given":"Wei-Li","family":"Hsu","sequence":"additional","affiliation":[{"name":"School and Graduate Institute of Physical Therapy, College of Medicine, National Taiwan University, No. 17, Xuzhou Rd., Zhongzheng Dist., Taipei City 100, Taiwan"},{"name":"Physical Therapy Centre, National Taiwan University Hospital, No. 1, Changde St., Zhongzheng Dist., Taipei City 100, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,5,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"330","DOI":"10.1016\/j.jse.2018.07.015","article-title":"The influence of lumbopelvic control on shoulder and elbow kinetics in elite baseball pitchers","volume":"28","author":"Laudner","year":"2019","journal-title":"J.
