- Abstract
Nowadays two main paradigms (theories) compete in motor control and motor learning research: computational approach and dynamical system approach. From the standpoint of computational approach the main mechanism of motor control and learning is the ability of the brain to "compute" (biological computer). The human brain computes applying many approaches and laws. One of the most popular approaches is Bayes statistics. According to the paradigm of dynamical systems the mechanism of motor control develops in time. That is to say, every moment of time it can be different. It depends on the state of the human body, specificity of the environment and personal aims. Referring to computational logic, for example, the human brain computes (estimates) the state of the motor system, the trajectory of the upcoming movement, the force developed by the muscles, the range, etc. The main computational approach is simplifying the complexity; that is to say, during motor control the human brain "straightens" many phenomena in the mind which are nonlinear in the periphery (in the movement itself). Computations are used in two main cases: a) for the performance of predicted movements (motor performance is estimated beforehand, without feedback) and b) computation with constant revision (feedback). According to the dynamical system approach the human brain cannot compute e. g. all the possible trajectories of movements in time because it is not only impossible but also uneconomical. Thus, in many cases computing is spontaneous and with "broken figures", i. e. with many mistakes. The article deals with the main motor abilities (dynamism, spontaneity, stability, adaptivity) and contemporary theories of motor control (reflexive, hierarchical, motor program, expedient, informational, system, scheme, balance point, dynamic systems, ecological, inner patterns and uncontrolled diversity). Much attention is paid to the possibilities of the application of those theories in sport and rehabilitation.
