Differences in body composition between three groups of students

Abstract

The purpose of this paper was to confirm whether there is any difference in body composition between the three groups: Group1 – females (N=25) aged 19–21, Group2 – females aged 22–24, (N=27), and Group3 – males aged 19–24 years (N=22). Respectively to determine whether gender and calendar age has an impact on the body composition of women and men. The parameters of the body composition applied in this re- search were: height of the body (height), body weight (weight), body fat (body fat), muscle mass (muscle), daily calorie intake (kcal), metabolic age (metabolic age), total body water (water), visceral fat (visceral fat) and body mass index (BMI). Measurements were performed at the Faculty of Education in Pristina. The basic statistical and distribution parameters that have been applied in this paper are Minimum, Maximum, Mean, Std. Deviation, Skewness, Kurtosis, max-D, and Kolmogorov-Smirnov test (K-S). To confirm the differences between the arith- metic mean of the groups the LSD-post hoc test was applied. The results obtained showed that differences were obtained in the arithmetic averages in all parameters of body composition between Group1 and Group2. But a statistically significant difference between these two groups has been gained in the metabolic age variable which shows that from the age of 22 in women begins a decrease in daily physical movements. Also, after processing the results by ANOVA analysis, significant statistical differences were obtained between the groups of females and the group of males, in the arithmetic mean in all variables of body composition p<0.01 (except for the variable of body composition Daily Calorie Intake (Kcal) p>0.38).
