Neglect of systematic rational physical activity always contributes to a persistent weakening of the state of health and especially often leads to the formation of various dysfunctions of the heart and blood vessels. The study was carried out in 2019-2020 on young men living in Central Russia (the city of Moscow and the Moscow region). In the work carried out, it was found that regular muscle activity in healthy adolescents and those with dysfunctions in the cardiovascular system provides a stable normalization of the parameters of cardiac activity. As a result of regular dosed physical training, all those under observation had a statistically significant increase in the vital capacity of the lungs. All physically training young men showed an increase in the level of general physical fitness. In all cases, the boys who increased their physical activity showed an increase in speed-strength capabilities and an increase in overall endurance. It can be considered that an increase in daily physical activity due to an increase in the distance covered on foot is a very effective means of improving the health of adolescents, including when they begin to develop disorders of the cardiovascular system. https://biomedpharmajournal.org/vol14no3/the-effect-of-regular-physical-activity-on-the-cardiovascular-system-in-students/ Adolescence Cardiovascular Diseases  Muscle Activity  Physical Training  Walking
