For coaches and scientists, it is of great interest to search for new directions in the methodology of training highly qualified sprinters, which can increase training effectiveness. In our opinion, one of these directions is the concept of training the shoulder girdle as a generator of driving force in sprinting, based on the principle of centrifugal forces generated by limb movements.

The purpose of the research was to conduct experimental studies to identify an alternative driving force of an athlete when running at maximum speed.

Research methods. Analysis and generalization of scientific and methodological literature, analysis of photographs, film records and cyclograms with segmentation of body parts, curvimetry and scaling were used.

Research results. A different mechanism of the driving force in sprinting has been revealed. For running at maximum speed, the driving force generated by the powerful work of upper limbs is used. Arms, which until now have been perceived as a vestige, in reality are the most important factor in fast running. In sprinting, 90% of the energy falls on vertical interactions, it is the work of the arms that sets the magnitude of vertical interactions, which results in a centrifugal force directed downward and acts as a factor of tendon deformation.
Running at maximum speed is carried out due to the deformation of the tendons (Achilles tendon, patellar ligament, tendon of the rectus femoris and medial ligament and ligaments of the plantar muscles of the foot) and their subsequent return work.

Conclusion. It is advisable to use exercises in the training process of sprinters aimed at developing the strength of the shoulder girdle, since the generator of the driving force in sprinting is not muscular-contractile work, but the deformation of the tendons of the legs as a result of the action of centrifugal forces that occurs during the active work of the arms.
