Figure 1. Time analysis during 5 x 100 m all-out swimming. Results are presented as mean ±SD. Analysis from the ANOVA 2(group) x 5(time) showed a significant main effect for time by increasing swimming time in the 3rd, 4th, and 5th repetitions for both IN and OUT conditions. **(p = 0.01) and *** (p = 0.001) relative to the first swimming bout (B1). G = Hedges's g analysis. Probability is presented in brackets.
