The purpose of this study was to asses whether compression affects movement mechanics and increases sport performance.

Eight subjects participated in the study ([mean±SD] age: 25.6±10.3 years, height: 177.9±2.9cm, weight: 71.9±7.4kg). Passive range of movement was evaluated by means of Thomas, Ridge and hip flexion with straight leg tests. The active range of movement was assessed during vertical jump. Values were determined using 2D analysis. Jump height and peak force applied during impulse phase were used for performance comparison. Tests were performed in three different conditions, using compression shorts (warp knitted fabric 57% Polyamide and 43% Elastan), standard lycra shorts and underwear as a control using a balanced, randomised design.

There were no significant differences between the three conditions in the performance parameters, whereas compression significantly limited the hip range of motion (ROM) during either passive or active evaluations.

Compression garments act as functional bandages, allowing normal functional movement but restricting ROM. These limitations could have prophylactic effects, preventing injuries when suddenly exceeding the limit of individual joints.
