EXERCISE

: Compression garments are frequently used to facilitate recovery from strenuous exercise.

PURPOSE: To identify the effects of 2 different grades of compression garment on recovery indices after strenuous exercise.

METHODS: Forty-five recreationally active participants (n = 26 male and n = 19 female) completed an eccentric-exercise protocol consisting of 100 drop jumps, after which they were matched for body mass and randomly but equally assigned to a high-compression pressure (HI) group, a low-compression pressure (LOW) group, or a sham ultrasound group (SHAM). Participants in the HI and LOW groups wore the garments for 72 h postexercise; participants in the SHAM group received a single treatment of 10-min sham ultrasound. Measures of perceived muscle soreness, maximal voluntary contraction (MVC), countermovement-jump height (CMJ), creatine kinase (CK), C-reactive protein (CRP), and myoglobin (Mb) were assessed before the exercise protocol and again at 1, 24, 48, and 72 h postexercise. Data were analyzed using a repeated-measures ANOVA.

RESULTS: Recovery of MVC and CMJ was significantly improved with the HI compression garment (P<.05). A significant time-by-treatment interaction was also observed for jump height at 24 h postexercise (P<.05). No significant differences were observed for parameters of soreness and plasma CK, CRP, and Mb.

CONCLUSIONS: The pressures exerted by a compression garment affect recovery after exercise-induced muscle damage, with higher pressure improving recovery of muscle function.
