[New method of determination and standardization criterion in dynamic muscular loads]

Laboratory and industrial investigations using physiologic and ergonomic approaches covered dynamic muscular efforts and revealed close correlation between inertial, kinematic characteristics of muscular movements and pulse rate in low, moderate and intensive locomotory activity. The investigations discovered a relationship between pulse rate and ergonomic characteristics in dynamic muscular efforts. Using the finding, the authors created ergonomic equivalent of pulse rate in dynamic muscular efforts, new method and criterion to regulate dynamic muscular effort according to its intensity. The investigations demonstrate that the new methods are more informative, if compared to the regular ones.
