5. Fig. 4
Mean drag force curves ± SD of the barefoot (thin line) and Hydro Boot (thick line) during extension-flexion in (A) women and (B) men. Stars indicate that the peak drag forces differed between these 2 conditions. ***p < .001.

6. Fig. 5
Mean ± SD forces in isometric and isokinetic conditions, and drag forces determined in barefoot and Hydro Boot conditions. All conditions differed (p < ) except peak flexion forces between isokinetic and Hydro Boot conditions marked (NS) in the figure. Abbreviations: BF, barefoot; HB, Hydro Boot; ISOK, isokinetic; ISOM, isometric; NS, not significant.
