Participants will perform a myofascial release session immediately before performing the 20-m wheelchair sprint test.

Participants will perform the 20-m wheelchair sprint test without receiving myofascial release or any other intervention.

Manual myofascial release will be applied to the upper limb muscles involved in wheelchair propulsion, including the biceps brachii, brachialis, and triceps muscles. The intervention will be performed by a trained physiotherapist using a handheld device, with 90 seconds of application per muscle group. The treatment will be administered immediately prior to the 20-meter wheelchair sprint test

The 20-m sprint course will be marked on a flat, obstacle-free surface at the same indoor facility where the athletes regularly train, under controlled environmental conditions (wind-free environment and ambient temperature of approximately 26°C). Sprint time (s) will be measured using an electronic timing system consisting of three infrared photocell gates, positioned at the starting line, the 10-m mark, and the finish line. Participants will be instructed to complete the 20-m distance as fast as possible. The test will begin from a stationary position, with the front wheels of the wheelchair positioned immediately behind the starting line. Two trials will be performed, separated by a three-minute passive recovery period. The fastest time recorded across the two trials will be used for statistical analysis.
