In a bobsleigh race, acceleration is crucial. The advantage obtained at this stage can increase several times at the finish line, so the main task of the overclockers is to ensure the maximum speed of the bob in the starting acceleration zone. At the same time, it is much harder to set a projectile weighing more than 100 kg in motion than to continue acceleration. In this regard, the effectiveness of the starting acceleration is determined by the ability of the accelerating one to transfer the highest speed to the projectile already at the start, which is due to the level of development of the starting and explosive force.The aim of the study is to study the space-time sequence of the locomotion of the starting effort in bobsleigh.The development of an effective method by improving the phase structure of the starting effort in bobsleigh is complicated by the lack of knowledge about its space-time (kinematic) sequence.Research methods. Angular kinematic characteristics of movement in the hip, knee and ankle joints were obtained during the implementation of the starting force, angular kinematic characteristics of these components of the starting force were established.The kinematic characteristics of the implementation of the starting effort were studied in 15 highly qualified bobsledders taking part in training camps. The study was conducted on the basis of the technique of marker high- speed video shooting.The results of the study. In the course of the work, the angular biomechanical characteristics of the components of the starting force in the acceleration phase in the bobsleigh were established.
