Morphology and Hydrodynamic Resistance in Young Swimmers

Six 9-, 11-, and 13-year-old, anthropometrically matched males and females were towed on the water surface via a mechanical winch at 1.3 to 2.5 ms −1 in increments of 0.3 ms −1 during a prone streamlined glide. Passive drag force of the 13-year age group was significantly larger than that of the 9-y...

Description
Summary:Six 9-, 11-, and 13-year-old, anthropometrically matched males and females were towed on the water surface via a mechanical winch at 1.3 to 2.5 ms −1 in increments of 0.3 ms −1 during a prone streamlined glide. Passive drag force of the 13-year age group was significantly larger than that of the 9-year age group at 1.9, 2.2, and 2.5 ms −1 , but not at 1.3-1.6 ms −1 . While anthropometry did not feature in any regression equation at any age for passive drag at velocities of 1.3 and 1.6 ms −1 , body mass was the best predictor of drag at 1.9 and 2.5 ms −1 .
