The interrelation between the Ketle index and the body component composition (muscle, fat, bone) in students with different levels of physical fitness

Abstract

The process of body mass increasing among the population becomes global, which updates the need for early diagnosis of obesity. An informative method of determining the body mass excess and obesity is the determination of muscle and fat components, as well as the analysis of correlations between weight, mass index and component composition of the body. Aim of the study was to identify the availability and character of relationship between body mass, index Ketle and body component composition in students with different level of physical fitness. Material and methods. Length, weight, body mass index, level of physical fitness, body component composition (muscle, fat, bone) have been investigated in 107 students (52 boys and 55 girls) of the main medical group studying at the Gorno-Altai State University. Results. Trained young man and girls with higher level of physical fitness were characterized by higher body mass, a positive correlation between weight, index Ketle, muscle and bone components and an inverse correlation between index Ketle and total fat. In young man and girls with low physical fitness, total mass and Ketle index positively correlated with the fat component. The nature of the correlation between body mass, Ketle index and composition of the body allows us to identify the trend of weight gain due to fat or muscle components.
