      <study_design>Randomization: Randomized, Blinding: Not blinded, Placebo: Not used, Assignment: Parallel, Purpose: Education/Guidance, Randomization description: Block randomization will be used, with the individual participant as the unit of randomization. The random allocation sequence will be generated using a random number table, and following baseline assessments, participants will be assigned to one of three groups: the neuromuscular training group, the core stability training group, or the control group (no intervention or routine training). Allocation concealment will be ensured using sequentially numbered, opaque, sealed envelopes. Outcome assessors will be blinded to group allocation.</study_design>

      <i_freetext>Intervention 1: Intervention group 1: Neuromuscular Training ،Participants in this group will perform a neuromuscular training program for 6 weeks, 3 sessions per week. Each session will last approximately 45–60 minutes and will include warm-up exercises, balance training, neuromuscular control exercises, proprioceptive exercises, lower-extremity functional exercises, and cool-down. All sessions will be supervised by the researcher. Intervention 2: Intervention group 2: Core Stability Training،Participants in this group will perform a core stability training program for 6 weeks, 3 sessions per week. Each session will last approximately 45–60 minutes and will include warm-up exercises, core muscle strengthening exercises, trunk control exercises, balance exercises, and cool-down. All sessions will be supervised by the researcher. Intervention 3: Control group: Participants in the control group will not receive either of the study interventions during the 6-week study period and will continue their routine taekwondo training. After completion of the study, the training program will be made available to them if requested.</i_freetext>
