Quantitative Methods and Research Status of Motor Coordination in Sport Skills

Motor coordination is a hot topic of research in many areas.Theories of Bernstein and dynamic system are the basic theories of motor coordination, which always are used to interpret motor coordination's formation, development, and characteristics.According to these theories, many quantitative methods has been designed to describe motor coordination objectively, all of which have its merit and demerit.Recently, there have many researches on the level of inter-limb or intra-limb coordination among many sport techniques, which have found some more economic coordination patterns.There are various coordination patterns, but they have some common characteristics.Moreover, inter or intra limb coordination variability is larger in the elite athlete's technique, it may reflect the flexibility of muscular-skeletal system, which is good for achieving movement task.There are few researches on the level of inter muscle or joint moment of force coordination in sport techniques, however, which still have found some more economic coordination patterns.The research trends of motor coordination in this area as follows:1) due to variety of sport techniques, which have different characteristics, the research of motor coordination will be on more sport techniques;2) making a further research on coordination variability based on theory of dynamical system, especially on elite athlete;3) exploring more the control parameters of motor coordination in sport techniques;4) expanding the research on the level of inter muscle or joint moment of force coordination in elite athlete's technique.
