The upper extremity fatigue will be created by requiring participants to perform consecutive sets of push-ups until task failure. Push-ups will be executed according to standardized ACSM guidelines, and repetitions will be recorded. Participants will first complete one maximal set to exhaustion, followed by a 1-minute rest period and a second maximal set. If performance in the second set exceeds 60% of the initial repetition count, additional sets will be performed after 1-minute recovery intervals. This sequence will continue until the participant's performance declines below 60% of the previous set, at which point neuromuscular fatigue will be considered achieved.

The lower extremity fatigue will be created by requiring participants to perform repeated 1-minute sets of maximal squat jumps until exhaustion. During each jump, participants will execute countermovement jumps and touch a low box with their hips to ensure standardized depth, under researcher supervision for proper technique. After completing an initial 1-minute maximal set, total jump count will be recorded. Following a 1-minute recovery period, a second 1-minute maximal set will be performed. If performance in the second set exceeds 60% of the first set's total repetitions, additional 1-minute sets will be completed after 1-minute rest intervals. This procedure will continue until jump performance declines below 60% of the previous set, at which point neuromuscular fatigue will be considered achieved.

The Purdue Pegboard Test (PPT) will be utilized to evaluate fine motor skills and the coordinated movement of the hands, fingers, and arms. Participants will sit comfortably in front of the pegboard to perform four distinct batteries, where the score for each section is determined by the number of items successfully placed or assembled within the allotted time. The first and second sections involve individual pin placement for 30 seconds using the dominant and non-dominant hands respectively; the third section requires simultaneous bimanual pin placement for 30 seconds; and the final section tests the ability to assemble pins, collars, and washers using both hands over a 60-second duration.

To ensure measurement precision, fixed anatomical landmarks-the greater trochanter, the lateral knee joint space, and the lateral malleolus-will be marked. At the start of the test, the participant will be positioned with the knee and hip joints at 90°. The researcher will passively move the participant's leg to a target angle of 45° flexion. After holding this position briefly, the leg will be returned to the starting position. Participants will be blindfolded to eliminate visual feedback. They will then be asked to actively reproduce the target angle. The absolute difference between the target angle and the actively reproduced angle will be recorded as the test score.
