Physiological characteristics of swimming strokes under water in a waterproof coverall and kit № 1

Abstract

Thefeatures of influence of physical activity of long swimming under water on dynamics of physiological parameters of underwater swimmer are investigated. A brief characteristic of the features of various strokes of swimming under water in a waterproof coverall is given. The factors influencing the choice of one or another stroke of swimming under water are indicated. The necessity of using methods of movement under water depending on their profitability and its influence on the efficiency of solving professional problems is substantiated. The possibility of maintaining breathing through the respiratory tube and self-contained breathing apparatus during swimming in and without waterproof coveralls has been studied. Possible criteria for choosing the ways to solve professional problems under water are formulated: data on changes in physiological parameters under the influence of a long load in swimming with various strokes and in various waterproof clothing. It is revealed that the nature and degree of influence of a prolonged load on the physiological functions of the organism depends on the methods of breathing and swimming under water. The results of studies characterizing differences in changes in physiological parameters of subjects depending on the chosen method of swimming are presented. It was established that under the influence of physical activity by means of various methods of swimming under water with a respiratory tube and an autonomous respiratory apparatus, progressive changes in physiological characteristics occur. Simultaneous movements of legs leads to a greater strain on the physiological functions of the body of a swimmer both in swimming with an autonomous respiratory apparatus and in kit No 1. The functioning of a circulatory system proceeds more actively by 4-5%, respiratory system by 2-3%.
