The degree of development of the respiratory system significantly determines the effectiveness of sports. Of great interest is the state of the respiratory system among representatives of power sports, and especially among weightlifters. Purpose of the study - to find out the level of development of the respiratory system in weightlifters. Methodology and organization of the study. A group of 33 young men was recruited, who weekly for at least 2 years were engaged in lifting the bar: twice a week - 10 people, four times a week - 12 people, six times a week - 11 people. The control group consisted of 15 young men who had not previously been involved in sports. Some parameters of the respiratory system were monitored with their subsequent statistical processing. Research results and discussion. Regularly engaged in lifting the bar had large volumetric and speed parameters of the respiratory system. Their highest values were among weightlifters who trained six times a week. Apparently, lifting the bar as training becomes more frequent ensures the development of the muscles of the chest and contributes to the expansion of the lumen of the bronchi, creating conditions for intensive gas exchange in the lungs and activation of metabolism throughout the body. Conclusions. Against the background of regular training, weightlifters experience a pronounced development of the external respiration system, which intensifies as training becomes more frequent
