The aim of this study was to compare equations for estimating percentage body fat from skinfold thickness in elite sport climbers by assessing their agreement with percentage body fat measured using dual-energy X-ray absorptiometry (DXA). Skinfold thickness was measured in a convenience sample of 19 elite sport climbers [9 women and 10 men; mean age 31.2 years (s=5.0) and 28.6 years (s=3.6), respectively]. Percentage body fat was estimated using 17 different equations, and it was also measured by DXA. A significant inter-methods difference was observed for all equations, except for Durnin’s equation in men (inter-methods difference: -0.57% and -0.29%; 1.96s: 5.56 and 5.23 for Siri’s and Brozek’s equation, respectively) and women (inter-methods difference: -0.67% and -1.29% for Siri’s and Brozek’s equation, respectively), and for Wilmore’s equation using Siri’s body fat equation in women (inter-methods difference: -1.86%). In women, the limits of agreement were lower when using Durnin’s equation compared with Wilmore’s equation (1.96s: 3.86% and 5.13%, respectively). In conclusion, of the 17 studied equations, Durnin’s equation was the most accurate in estimating percentage body fat in both male and female elite climbers. Therefore, Durnin’s equation could be used to assess percentage body fat in elite sport climbers if more accurate methods are not available. The generalizability of the results is limited by the fact that the sample was not selected at random.
