Anthropometric and body composition indicators of males and females between ages 20 and 39,9 years

Abstract

The objective of this study was to analyze anthropometric and body composition variables of males and females aged 20-40 years. The sample was made up of 4 groups: G1, n=70; G3, n=70, males and females aged 20-29,9yo respectively; G2, males=20 and G4, females = 19 aged 30-39,9yo. Subjects were evaluated for height (H, cm), weight (W, kg), skinfolds (SKF, mm), percent fat (%fat) and Lean Body Mass (LBM, kg). Body density was estimated according to equations by Petroski (1995) and %fat according to Siri (1961). Descriptive statistics, independent t test and single-sample t test were used for data analysis. Significant differences were found for males on SS and TR SKF, density, %fat and FM between age groups, and for females at calf SKF, and %fat. Significant differences were observed between indicators/mean values from other published reports when compared to this study’s results. In conclusion, males were shown to have much larger variability in all analyzed variables that their female counterparts.
