Summary This investigation aimed to compare hydrostatic weighing ( HW ) with near‐infrared interactance ( NIR ) and skinfold measurements ( SKF ) in estimating body fat percentage ( FAT %) in rowing athletes. FAT % was estimated in 20 elite male rowers (mean ± SD : age = 24·8 ± 2·2 years, height = 191·0 ± 6·8 cm, weight = 86·8 ± 11·3 kg, HW FAT % = 11·50 ± 3·16%) using HW with residual volume, 3‐site SKF and NIR on the biceps brachii . Predicted FAT % values for NIR and SKF were validated against the criterion method of HW . Constant error was not significant for NIR (−0·06, P = 0·955) or SKF (−0·20, P = 0·813). Neither NIR ( r = 0·045) nor SKF ( r = 0·229) demonstrated significant validity coefficients when compared to HW . The standard error of the estimate values for NIR and SKF were both less than 3·5%, while total error was 4·34% and 3·60%, respectively. When compared to HW , SKF and NIR provide similar mean values when compared to HW , but the lack of apparent relationships between individual values and borderline unacceptable total error may limit their application in this population.
