Adaptarea sistemului cardiovascular al elevilor - sportivi de 10-11 ani la antrenamentul în circuit [Articol]

Abstract

This paper investigated the adaptation of the cardiovascular system of 10-11 year old student athletes (girls and boys) to circuit training. The investigations were carried out after four months of circuit training. The objectives of the paper: determining the indicators of the functional state of the cardiovascular system of 10-11 year old athletes; evaluating the results obtained in relation to the normative values of the researched indicators; drawing conclusions. The following indicators were determined: the economy coefficient, the Robinson index, the adaptability index and the Kerdo index. The results obtained indicate the state of fatigue of the wrestlers included in the experimental research, which occurred after four months of training, with boys having a higher degree of fatigue than girls. Both girls and boys, freestyle wrestlers, have average physiological reserves of the cardiovascular system, which ensures their satisfactory adaptation to physical exertion. Sports training has left its mark on the functional state of the cardiovascular system of 10-11 year old wrestlers, which is manifested by the predominance of the influence of the parasympathetic vegetative system on the activity of the heart at rest, which activates economically, especially in girls. We recommend circuit training to increase the adaptive potential of the body of student wrestlers, but also the individualization of physical efforts in accordance with the body’s economic coefficient, the determination of this indicator being necessary to prevent sports overtraining.
