Participants in both intervention groups completed sessions performed three days a week over eight weeks. Pain intensity, fear of movement, and functional abilities were assessed using validated tools, including the Visual Analogue Scale (VAS), Tampa fear of movement scale and the Functional Movement Screen (FMS).<br> <b>Results:</b> Both interventions significantly improved pain, kinesiophobia, and functional movement. However, Core stability exercises demonstrated superior results compared to NASM exercises by alleviating pain, reducing fear of movement, and improving functional mobility.. Pain scores showed a significantly greater reduction in the core stability group compared to the NASM group (p=0.001), and also Movement-related fear scores significantly lower in the core stability group (p=0.003). The core stability group demonstrated significantly superior improvements in functional movement scores (p=0.009).<br> <b>Conclusion:</b> Core stability exercises, particularly under online supervision, are effective in managing pain, reducing fear of movement, and enhancing movement performance in elite Taekwondo athletes with CNSLBP. Core stability exercises, proven superior to NASM interventions, should be integrated into rehabilitation programs to alleviate clinical symptoms and enhance athletic performance. Additionally, the findings underscore the potential of online supervision as a viable alternative for effective training and rehabilitation.</span></span></span></div> <span style="font-size:12pt"><span new="" roman="" style="font-family:" times=""><span style="color:black"></span></span></span> Core Stability Exercises, Trunk Muscle Endurance, Physical Therapy, Exercise Therapy, Pain Management. 0 0 http://ptj.uswr.ac.ir/browse.php?a_code=A-10-686-1&slc_lang=en&sid=1 Somayeh Karimi Som.k.421@gmail.com No Department of Sports Injury and Biomechanics, Faculty of Sport Sciences and Health, University of Tehran, Tehran, Iran.
