title: [Integration of motor and autonomic functions during muscle work].
abstract: In isometric efforts small energy expenditure was found to involve an inadequate increase of the heart rate and blood pressure. In dynamic cyclic loads, the heart rate and blood pressure increase occurs linearly, corresponding to the increase of O2 consumption and systolic index. Voluntary relaxation of muscles in the course of cyclic load involves small values of the O2 consumption and systolic index, as well as low heart rate and blood pressure. In natural cyclic and noncyclic motor activity, the character of integration of the motor and vegetative functions depends on the relative weight of each of the biomechanical modes.
