dc.description.abstract PURPOSE: The purpose of this study was to identify potential differences in impulse force generated during the vertical jump while wearing commercially available compression shorts as compared to non-compressive, loose fitting gym shorts.<p> HYPOTHESIS: Leg muscle compression will produce no significant difference in muscle performance variables generated during a standard vertical jump test when compared to no compression.<p> METHODS: Twenty five physically active males between the ages of 18 and 30 were recruited for this study. Each subject was asked to wear 4 types of shorts: non-compressive gym shorts (representing a control), regular fitting compression shorts (by manufacturer standard), undersized compression shorts (one size smaller than manufacturer standard), and oversized compression shorts (one size larger than manufacturer standard). The subjects were familiarized with the testing procedures and then completed the three randomized conditions on the same day. The performance tests consisted of 3 sets of 10 countermovement vertical jumps performed upon a force platform. The dependent measures included: velocity at takeoff (Vto; m·s), fatigability across jumps (Vf ; m·s) and surface electromyography (EMG; volts).The maximal impulse generated was taken from the highest curve out 4 of the 10 jumps and average power was determined across the 10 jumps in each condition. The individual compression values were then determined in each condition for each subject with the use of a custom made compression quantification device. Results: There were no significant differences (P>.05) in Vto, Vf, and EMG across compression levels. Conclusions: The compression garments produce no significant change in the forces generated during the vertical jump. en
