Objective of the study was to improve the technique of athletic locomotions based on the agreement of applied force with the force of gravity.
Methods and structure of the study. To study the university mountaineers’ technique of locomotions based on the agreement of applied force with the force of gravity, we considered such parameter of force as a vector. The vector of applied force in most athletic locomotions should pass through the center of gravity of the system. Otherwise, there will be an undesirable rotation.
During the experiment, we took measurements to determine the degree of agreement of force applied by the athletes while going up the climbing wall with the existing force of gravity. By measuring the angle between the gravity vector and the applied force vector, we were able to determine the optimal value of the applied force. The starting point for measurements was the gravity vector directed vertically down.
Results of the study and conclusions. We conducted a comparative analysis of the athletes’ technique of locomotions during climbing, when the vector of gravity and that of the force applied with the left hand were or were not on the same line.
Proceeding from the received data on the agreement of applied force with the force of gravity, it is possible to adjust the process of technical training of athletes in various sports in order to achieve the optimal form of locomotions when mastering technical actions. In most cases, once coaches have mastered this methodology through the prism of measurements of the angle between the force vectors, visual observation of the athletes’ locomotions and their appropriate correction are enough thereafter.

Keywords: sports, technology, locomotion, indicators of sports mastery, force, improvement of locomotion actions.
