Effects of compression garments on recovery following intermittent exercise

The objective of the study was to examine the effects of wearing compression garments for 24 h post-exercise on the biochemical, physical and perceived recovery of highly trained athletes. Eight field hockey players completed a match simulation exercise protocol on two occasions separated by 4 weeks after which lower-limb compression garments (CG) or loose pants (CON) were worn for 24 h. Blood was collected pre-exercise and 1, 24 and 48 h post-exercise for IL-6, IL-1 beta, TNF-alpha, CRP and CK. Blood lactate was monitored throughout exercise and for 30 min after. A 5 counter-movement jump (5CMJ) and squat jump were performed and perceived soreness rated at pre-exercise and 1, 24 and 48 h post-exercise. Perceived recovery was assessed post-exercise using a questionnaire related to exercise readiness. Repeated measures ANOVA was used to assess changes in blood, perceptual and physical responses to recovery. CK and CRP were significantly elevated 24 h post-exercise in both conditions (p < 0.05). No significant differences were observed for TNF-alpha, IL1-beta, IL-6 between treatments (p > 0.05). Power and force production in the 5CMJ was reduced and perceived soreness was highest at 1 h post-exercise (p < 0.05). Perceived recovery was lowest at 1 h post-exercise in both conditions (p < 0.01), whilst overall, perceived recovery was greater when CG were worn (p < 0.005). None of the blood or physical markers of recovery indicates any benefit of wearing compression garments post-exercise. However, muscle soreness and perceived recovery indicators suggest a psychological benefit may exist.
