METHOD OF STUDY OF THE STATIC LOAD EFFECT ON THE CONDITION OF THE CARDIOVASCULAR SYSTEM USING RHEOGRAPHY AND ELECTROCARDIOGRAPHY

of Ukraine on Physical Education and Sport Influence of endogenous and exogenous factors on the course of adaptive reactions of the body to physical exertion of various intensities (state registration number 012U108187).Introduction.Physiological studies of the body of athletes differ from studies that are conducted on non-athletes.This is due to the fact that in sports it is quite important to know about the state of different organs and systems of organs not during rest, but during the exercise, as well as during the recovery of the body.There are certain requirements for devices used in sports physiology.They should quickly perceive information and not interfere with the athlete during exercise.It is important to study the functioning of the cardiovascular system during exercise, since this system is of great importance for the success and effectiveness of the athlete [1,2,3,4]. / METHODS AND METHODOLOGIESarticle provides a detailed description of the equipment, content, stages, essence and sequence of collaborative actions of the supervisor, researchers, and subjects in the scientific-practical process.This study allows for the recording of the cardiovascular system's state during the development of maximal force, the maintenance of that force level and throughout a six-minute recovery period.Conclusions.We established and described a methodology for investigating the athlete's cardiovascular system during static loading and recovery, with simultaneous recording of rheography, electrocardiography, blood pressure measurement and dynamometer data acquisition.The results demonstrate clear and valuable insights.This comprehensive methodological approach to studying the athlete's cardiovascular system can be used in practice.Conducting the described complex study is possible with long-term practice of coordinated actions by a team of scientists.The testing of the proposed methodology with the participation of 18 volunteers proved to be successful and effective.
