The effect of different recovery methods on muscle swelling recovery after muscle fatigue

This paper's purpose is to investigate the effect of passive recovery (PR), active recovery (AR), vibration recovery (VR) and cryotherapy recovery (CR) on muscle swelling Degree (SD) after muscle fatigue. 20 healthy male college students were enrolled in the study. SD of the biceps brachii of the non-handedness was measured. The differences and recovery effects of SD at different detection time points were tested by one-way repeated measures ANOVA. Results shows that Continuous AR of decreasing intensity cannot improve recovery of fatigue muscle and even increase SD after active concentric contraction and passive pulling at constant speed in low intensity of 45 degrees/s. In addition, CR can effectively control tissue injury and SD problem due to centrifugal motion.
