“…Accordingly, thanks to the myogenic and nervous mechanisms of heart regulation, cardiac output will be reduced, which leads to a decrease in MBV [2,21]. In young bodybuilders, on the contrary, there is an increase in MBV even in the conditions of a powerful static effort, which was mainly provided by an increase in the force of contractions of the left ventricle and a corresponding increase in stroke volume [1,16].…”

The cardiovascular system is one of the leading functional systems of the body, which ensure and maintain the proper level of physical performance of the body during physical exertion. Bodybuilding is one of the areas of sports activity in which taking into account the individual characteristics of the adaptation of the circulatory system to powerful muscle work of significant intensity is decisive for building an optimal training regimen. Anatomical and physiological remodeling of the heart as a result of regular sports leads to changes in the pumping function of the myocardium, as well as indicators of central and peripheral hemodynamics. Currently, there is a problem of insufficient study of the functional changes of blood vessels in response to a static regime of physical exertion in the early post-workout period. The purpose of the research is to study the characteristics of the reaction of blood vessels during the early recovery period after dosed physical exertion of a static nature. During the study, 34 young men were examined in the following groups: 1 group – persons engaged in bodybuilding; 2 group – young men engaged in fitness; 3 group – untrained persons. Maximum arbitrary static force was determined in all examined persons using a static dynamometer DS-500, static load was modeled by holding on a static dynamometer for 30 seconds an effort corresponding to 50 % of the maximum static force. Functional changes of blood vessels and central hemodynamics were registered by the method of tetrapolar thoracic impedance rheoplethysmography using the computerized diagnostic complex “Cardio+” (Ukraine). Statistical data processing was carried out using the computer program IBM SPSS Statistics (version 26), using non-parametric methods of evaluating the obtained results. It was established that static exercise in young bodybuilders leads to an increase in minute blood volume due to optimal physiological changes in central hemodynamic parameters. In persons engaged in fitness and in untrained young men, the minute volume of blood decreases and circulation conditions deteriorate immediately after exercise, which complicates the processes of rapid recovery after physical exercise in a static mode. A decrease in vascular resistance to blood flow with a simultaneous increase in minute blood volume was revealed immediately after static exercise in young bodybuilders compared to individuals engaged in fitness and untrained individuals. It was established that the circulatory system of young bodybuilders is most optimally adapted to static loads compared to persons engaged in fitness and untrained young men.

“…The deep nature of the phenomenon named after the discoverer was also studied by physiologists in the following decades. However, sports physiologists pay much more attention to physical exercises of a dynamic nature [3,14]. In the vast majority of sports, muscle activity is dynamic in nature, but recently there has been a growing interest in health physical culture in static exercises [5,15], to the study of which a significant contribution was made by the domestic scientist O. R.…”

In the vast majority of sports, muscle activity is dynamic in nature, however, recently sports physiologists have been paying considerable attention to static exercises. The deep mechanisms of the phenomenon of static efforts have been studied since its discovery, but there are still many gaps in biological knowledge regarding the issue of the impact of static load on the functioning parameters of the circulatory system in individuals with different anthropometric characteristics. The purpose of the work is to study the influence of dosed static load on the parameters of the circulatory system during the early recovery period in people with different body mass indexes. During the study, 36 young men were examined, who were divided into two groups according to the body mass index (BMI) criterion – young men with a normal BMI (nBMI group, the average value of BMI in the group – 21.6), as well as young men with an increased BMI (group iBMI, the average value of BMI in the group is 28.1). Static load (SL) was modeled by maintaining a force equal to 50 % of the maximum static force for 15 seconds on a static dynamometer DS-200. Before exercise and within 3 minutes after its completion, the main parameters of central hemodynamics were measured in the examined persons using tetrapolar thoracic rheoplethysmography on the computerized diagnostic complex "Cardio+" (Ukraine). Statistical data processing was carried out using the computer program IBM SPSS Statistics (version 26), using non-parametric methods of evaluating the obtained results. We have established that in the initial state, young men with a normal body mass index differ from persons with an increased body mass index by a lower value of heart rate, total peripheral resistance and blood pressure, as well as higher values of stroke and minute blood volumes, stroke and cardiac indices. The dosed static load leads to the same nature of changes in the parameters of the circulatory system in all examined persons, regardless of the body mass index. Differences in body mass index affect only the degree of manifestation of certain changes. A more significant manifestation of the Lingard phenomenon was recorded in young men with an increased body mass index, as evidenced by a greater degree of deviation of the measured parameters of the circulatory system in response to static exercise.
