Interventions/Control_1
Participants will perform direction-specific whole-body reaction time tasks using a whole-body reaction time measurement system. In response to visual stimuli, participants will move by a small jump in five directions: upward, forward, backward, leftward, and rightward. Five trials will be conducted in each direction, and the mean of the middle three trials (excluding the maximum and minimum values) will be used for analysis. Body composition (height, weight, and body fat percentage) and toe-grip strength will also be measured. The intervention will be performed only on the assessment day and will require approximately 60 minutes per participant.
