The negative factor in this performance is the bending and extension of the joints of the body in which the center of the weight of the mass of the body during the performance and this proves the importance of research in the researcher to know the impact of infrared radiation after the kinetic changes during the motor performance of a series of motor on the machine mind, The question is whether muscle agility and muscle flexion affect the technical performance of the brain.
