Day's periodicity of vegetative functions for swimmers taking into account the phases of days-long biorhythms

Abstract

In this work we studied day's periodicity of indexes of cardiovascular and respiratory systems for swimmers depending on the phases of physical multi-day biorhythms at the beginning of the competitive stage of preparation. In a sports camp 5 girls and 11 young men age 15-17 masters of sports and candidates for master of sports at swimming, took part at scientific research. The presence of two peaks of sizes of indexes of vegetative functions which are observed after the first and third training is educed. According to the level of functional readiness, the subjects were divided into 3 groups: with a good functional state, with its deterioration as a result of an acute respiratory disease or overwork, and with a satisfactory state. An assessment of the functional state of each athlete was made at the beginning and end of the training camp. Health status, sleep, well-being assessment, etc. about swimmers was taken into account in the analysis of the material. During the exchange of rest, the indicators of vegetative functions most fully reflect the state of the athlete on the day of the examination.
