Validation of generalized and specific equations anthropometric to estimate the percentage of body fat in male Physical Education students

Abstract

The objective of this study was to verify the validity of the specific equations Guedes and Guedes(7) and generalized by Petroski(9) in male college students. One hundred four students of Physical Education with a mean age of 21.7 ± 2.7 participated in the current study. They were submitted to the hydrostatic weighing (HW) and anthropometry (skinfolds and body circumferences). No statistically significant difference between measurements of fat percentage by PH and nine equations Petroski(9) was observed. All results obtained by equations Guedes and Guedes(7) showed significant differences when compared with the PH. Among the equations analyzed eight developed by Petroski(9) showed concurrent validity in the study sample.
