Introduction. It remains relevant to continue studying the effect of various types of physical activity on the body as a whole and its individual organs [1]. Special attention in such studies is traditionally paid to the dynamics of vital signs [2]. Thus, these observations are designed to collect scientific facts and data that can help improve athletic performance in novice athletes, especially in power sports.
The purpose of the study is to determine the degree of development of the respiratory system in young kettlebellists.
Methodology and organization of the study. The study involved 14 kettlebell athletes aged 18 to 19 years (experimental group - EG) who regularly trained for at least two years and 14 young men (18-19 years old) who were not involved in sports (control group – KG). The morphofunctional characteristics of the lungs were monitored and the value of the Student's criterion was calculated.
The results of the study and their discussion. The volume of the vital capacity of the lungs in KG was 4.15 ± 0.29 liters, while it in KG was 6.05 ± 0.37 liters. There were significant differences between the groups examined in terms of the volume of the forced vital capacity of the lungs. In boys of KG, this indicator was 3.74 ± 0.21 liters, and in EG – 5.91 ± 0.30 liters. The volume value of forced exhalation in the first half second and in the first second of the kettlebell weights exceeded the level of participants KG by 32.81% and 36.1%. As a result, the kettlebell weights had biologically very favorable ratios of the magnitude of the forced output within a second and the volume of the vital capacity of the lungs. In the observed kettlebell weights, the value of the average volumetric velocity in the zone of 25-75% of the value of the forced vital capacity of the lungs was significantly higher than that in the control group.
Conclusion. Young weightlifters have a high degree of lung development. Due to the great fitness of their respiratory system, there is reason to look at kettlebell lifting as a variant of the development of the respiratory system among young people.
