Comparison of the Instantaneous Effects of Graston Technique and Static Stretching on Ankle Range of Motion and Vertical Jump Performance in Athletes

Universal Goniometric Measurement (UGM)

时间窗: Change from Baseline UGM at 10 minutes

The participant lies supine with the knee extended and the ankle hanging over the end of the table. Inversion, eversion, dorsi flexion and plantar flexion active ankle range of motion can be assessed using a goniometer. In the universal goniometric measurement, the 90-degree right angle between the 5th metatarsal and fibula is considered the starting position of the ankle at 0 degrees for dorsi and plantar flexion. Since the gastrocnemius covers two joints, the muscle should be relaxed by placing a thin pillow under the knees during the measurement. The pivot point of the goniometer is placed on the lateral malleolus. The fixed arm is held parallel to the lateral midline of the fibula. The movable arm follows the lateral midline of the 5th metatarsal bone. Care is taken to avoid inversion and eversion of the foot during measurement.

Vertical Jump Test (VJT)

时间窗: Change from Baseline VJT at 10 minutes

It is a test with a high reliability rate for determining the athlete's jumping power. It was developed by Dr. Dudley Allen Sargent in 1921. In the test, a tape measure is attached to the wall. Stand upright with the feet shoulder-width apart and the dominant side facing the wall. Without lifting the feet off the floor, the highest point that can be reached on the tape measure is marked. Then, immediately after bending down by bending the hips and knees, the highest point that can be reached by jumping is asked to be marked by hand. The distance difference between both points is determined. The test is repeated three times and the best result is recorded in centimeters.
