STUDY OF QUALITATIVE AND QUANTITATIVE BODY COMPOSITION IN YOUNG PEOPLE WITH JOINT HYPERMOBILITY

The aim of the study was to assess the qualitative and quantitative composition of the body in young people with different indicators of body mass index and to search for associations with the formation of joint hypermobility. 86 young people were examined for the presence of joint hypermobility, 60 of them underwent X-ray densitometry using the Total body program. There were no significant differences depending on the presence of hypermobility of the joints, as well as the relationship of a low body mass index and the formation of hypermobility. When comparing body composition in groups with different BMI, a decrease in the percentage of fat mass from 34.12 ± 0.72 to 27.47 ± 1.54 and a simultaneous increase in the percentage of lean mass from 65.87 ± 0.72 to 72.53± 1.54 in individuals with a deficit of body weight (BMI <18.5 kg / m2), these differences reached the level of statistical significance (U = 74, p = 0.0015). The decrease in the amount of adipose tissue with a decrease in BMI occurs mainly due to the lower extremities (7.86 ± 0.28 and 5.25 ± 0.34 kg) and the trunk (9.55 ± 0.43 and 5.17 ± 0.54 kg), these patterns are also true for the dynamics of a decrease in lean mass.
