The aim of the present study was to compare different body composition prediction formulas with the reference method,
DEXA, in the context of Colombian professional women’s soccer during a competitive season. The purpose of this
was to determine which of these formulas most closely replicates the gold standard and could offer an alternative
for evaluating body fat percentage (%) and lean mass in the absence of more precise methods. Formulas were used
to calculate body fat percentage using two components, specifically, those conceived by Yuhasz (15.17 [13.98 –
16.72]%), Durnin and Rahaman (25.57 [24.5.-.28.07]%), Jackson and Pollock (16.71 [14.33 – 19.33]%), and Durnin and
Womersley (24.90 [24.02 – 27.01]%). For five components, lipid mass was calculated from body weight (19.80 [17.80
– 22.30]%), whilst DEXA provided body fat percentage data (23.94 ± 3.51%). A cross-sectional analytical study with nonprobabilistic
convenience sampling was conducted of 24 female soccer players from two first-division teams. A total
of 26 anthropometric variables were measured. Descriptive analysis was performed using SPSS v.21, in addition to
correlation (SP), Lin’s concordance, and Bland and Altman analyses. The lowest inter-method difference relative to
DEXA was obtained via the Durnin and Womersley formula, with a value of – 0.70, indicating that fat % estimates would,
on average, overestimate DEXA by a value of 0.7. Durnin and Womersley formula produced the closest body fat % values
to those produced by the reference method, DEXA.
