What this trial measures
- Squat Jump HeightBaseline on Day 1 to Immediately after Intervention on Day 1
Subjects will be instructed to jump upwards from the starting squat position as high as possible. Subjects will perform 3 to 6 jumps with 3 consecutive jump heights being within 5% of each other to ensure maximum jump height is achieved. There will be a one-minute rest between jumps. * Starting position. Subjects will assume the starting squat position with their hips at 90°, knees at 120°, and ankles at 85° as positioned by the PI. An adjustable plyometric jump box will be used to standardize the starting position. Hands will be resting across their chest with the trunk and head positioned straight ahead. * Squat Jump: Subjects will be instructed to jump as high as possible and land in a comfortable position. Hands will remain across the chest for the duration of The Optojump photoelectric cell system (OptoJump) will be used to record jump height. OptoJump demonstrates strong concurrent validity and excellent test-retest reliability for the estimation of vertical jump height
- Range of Motion of Ankle DorsiflexionBaseline on Day 1 to Immediately after Treatment on Day 1 and at End of Test Session on Day 1
Knee-to-wall ankle dorsiflexion test: * Ankle dorsiflexion ROM (distance from wall - cm) is the maximum distance of the big toe from the wall while maintaining contact between the wall and the knee with the heel on the ground. * The subject will repeat the Knee-to-wall ankle dorsiflexion test three times at this maximum distance to allow the PI to record three goniometer measurements of ankle dorsiflexion ROM (degrees°).
