Measurement of VL.
To measure the thickness of the VL, the midpoint of the line drawn between the superior iliac anterior spine and the upper edge of the patella was identified. Starting from this point, a measurement was taken laterally, extending by 10% in both directions (ICC: 0.83).Each muscle group underwent 3 measurements, and the average values were documented in cm.Moreover, the cross-sectional area (CSA) of the Hamstring (H) and RF muscles were assessed by tracing the muscle borders on 3 occasions. The resulting mean values were recorded in square centimeters (cm²).
