Micro- injury (exercise-induced muscle damage, EIMD) will cause a temporary decline in muscle function, if not handled properly, it could cause more serious injury or overtraining, and even lead to the end of the athletes ' sports life. However, some studies have shown that an appropriate period of eccentric exercise training resulted in EIMD while promoted heart muscle fiber hypertrophy and corresponding muscle growth faster than exercise training, and there are the typical " repetitive training effect" , ie after a period of the EIMD recovery, the muscle' s injury or delayed onset muscle soreness (DOMS) caused by the same movement is significantly reduced. So its deep study could help to guide the athlete to avoid or mitigate the negative effects which brought by EIMD, while could help to further clarify the process of the body to adapt to exercise training or mechanism. 展开更多
