How-ever, existing researches indicated that appropriate centrifugal exercise training can boot muscle fiber hypertrophy and corresponding muscle strength growth better than centripetal exercise training, and has a typical “repeated training ef-fect”, i.e. within a certain period after recovery from SKSMD, the damage or delayed muscle ache caused by muscle repeating the same exercise is significantly reduced or alleviated. Therefore, in-depth study of it is conducive not only to guiding athletes to prevent SKSMD or negative effects brought by SKSMD, but also to further describing the proc-ess or mechanism for the body to adapt to exercise training. At present, the inducement mechanism of SKSMD is not clear; essentially various hypotheses can be reduced into the theory of mechanical damage and the theory of metabolic disorder. However, no matter which mechanism induced SKSMD, a lot of experimental results have proved that pro-found metabolic changes occurred in the process of SKSMD. Therefore, systematic study of SKSMD from the per-spective of metabolism will become an important direction in the study in this area.
