The aim of the study was to identify differences in obesity-related parameters between active sports students and semi-active or sedentary students, differentiated by sex, in order to optimize health. The study sample included 286 students, of which the male experimental sample consisted of 86 active sports students, age X ± SD 21.25 ± 0.32 years; height X ± SD 181.08 ± 3.52 cm; control group consisting of 89 semi-active students aged X ± SD 21.07 ± 0.1.13 years; height X ± SD 182.11 ± 1.32. The female experimental sample includes 57 active sports students, age X ± SD 21.02 ± 0.92 years; height X ± SD 167.48 ± 1.34 cm; the control group includes 54 semi-active students aged X ± SD 21.57 ± 0.1.98 years; height X ± SD 168.42 ± 1.76. The study used a thalliometer, Tanita Health Ware software and Quantum Resonance Magnetic Analyzer equipment to investigate height (cm), Body Mass Index (BMI), muscle mass (kg, %), as well as the obesity analysis report, and componential analysis of body and nourishment. The differences registered between the samples of active and semi-active sports subjects were predominantly statistically significant for p < 0.05. The differences registered between the samples of active and semi-active sports subjects were predominantly statistically significant for p < 0.05. The most important parameters regarding obesity and body composition that registered significant differences between the two male groups were in favor of the group of active athletes: triglyceride content of abnormal coefficient 0.844 (CI95% 0.590-1.099), abnormal lipid metabolism coefficient 0.798 (CI95% 1.091-0.504), obesity degree of body (ODB %) 10.290 (CI95% 6.610-13.970), BMI 2.326 (CI95% 1.527-3.126), body fat (kg) 2.042 (CI95% 0.918-3.166), muscle volume (kg) 2.565 (CI95% 1.100-4.031), Lean body weight (kg) 2.841 (CI95% 5.265-0.418). In the case of female samples, the group of active sportswomen registered the biggest differences compared to the group of students who were significantly active in the parameters: abnormal lipid metabolism coefficient 1.063 (CI95% 1.380-0.746), triglyceride content of abnormal coefficient 0.807 (CI95% 0.437-1.178), obesity degree of body (ODB%) 8.082 (CI95% 2.983-13.181), BMI 2.285 (CI95% 1.247-3.324), body fat (kg) 2.586 (CI95% 0.905-4.267), muscle volume (kg) 2.570 (CI95% 0.154-4.985), lean body weight (kg) 4.118 (CI95% 1.160-7.077). The results of the study directly facilitate the understanding of the complexity of the impact of obesity on multiple parameters of body composition and health.
