By comparing the time of the same distance swum with and without an added resistance, under the assumption of an equal power output in both cases, the drag of 73 top swimmers was estimated. The active drag Fr(a.d.) at maximal swimming velocities varied considerably across strokes and individuals. In the females Fr(a.d.) ranged from 69.78 to 31.16 N...

... where D is the drag force (in N), ρ is the density of water (in kg/m 3 ), v is the swimming speed (in m/s), S is the projected frontal surface area (FSA) of the swimmers (in m 2 ), and CD is the coefficient of drag (changing according to shape, orientation, and Reynolds number). There are two types of drag: (i) active (DA) -the water resistance induced to a body while swimming (Kolmogorov and Duplishcheva, 1992), and (ii) passive (DP)drag produced during the displacement of a towed body, i.e., without relative movement of the body segments in the aquatic environment (Pendergast et al., 2005). ...
