Studies of features of arm stroke external dynamic characteristics in dolphin-style swimmers with a subsequent correction of the position of body segments in the range of model parameters

Aim. The article deals with the assessment of speed-strength characteristics of arm strokes in dolphin-style swimmers and development of the method for correcting their individual force course with the help of the training equipment. Materials and methods. We conducted the study with the help of the device for arm strokes registration - RGD-2, which allows us to assess the speed-strength course (SSC) of an arm stroke. Two swimmers from the Yunika youth sports school participated in the study: athlete A (Candidate for Master of Sport) and athlete З (Candidate for Master of Sport). Both athletes are dolphin-style swimmers. Results. We used the method of forced movement restriction (mechanical restriction of movement directions) to prove the possibility of creating the training equipment, which imitate the kinematics of elite dolphin-style swimmers arm strokes, with its subsequent implementation in the training for technique improvement. Conclusion. We established that the method proposed for correcting the individual strength course of arm strokes can be effectively used to improve arm strokes technique.
