Contrast bathing (CB) and compression garments (CG) are widely used to promote recovery. PURPOSE: To evaluate CB and CG as regeneration strategies after exercise-induced muscle damage (EIMD). METHODS: Baseline values of muscle soreness, serum creatine kinase (CK) and myoglobin (Mb), joint range of motion, limb girth, 10- or 30-m sprint, countermovement jump (CMJ), and five repetition maximum squat were completed by 26 young men who then undertook a resistance exercise challenge (REC) to induce EIMD: 6x10 parallel squats at 100% body weight with 5-s one repetition maximum eccentric squat superimposed onto each set. After the REC, subjects were separated into three intervention groups: CB, CG, and control (CONT). Forty-eight hours after REC, the subjects exercise performance was reassessed. CK and Mb were also measured +1, +24, and +48 h post-REC. RESULTS: CK was elevated at +24 h (increased 140%; increased 161%; increased 270%), and Mb was elevated at +1 h (increased 523%; increased 458%; increased 682%) in CB, CG, and CONT. Within-group large effect sizes for logeCK were found for CB at +24 h (0.80) and +48 h (0.84). Area under the Mb curve was lower in CB compared with CG and CONT (p <= 0.05). At +48 h, significant differences from baseline were found in all groups for CMJ (CG decreased 5.1%; CB decreased 4.4%; CONT decreased 8.5%) and soreness (increased 13%; increased 284%; increased 284%). Soreness transiently fell at +1 h compared with post-REC in the CB group. At +48 h, midthigh girth increased in CB (increased 1.4%) and CONT (increased 1.6%), whereas 30-m sprint time increased in CG (increased 2%). CONCLUSION: No hierarchy of recovery effects was found. Neither contrast bathing nor compression acted to promote acute recovery from EIMD any more effectively than passive conditions, although contrast bathing may transiently attenuate postexercise soreness.
