Note: n.a.–it does not apply. p < 0.05 together with its corresponding r is bolded. Pearson correlation coefficients with 5 m turn-in time, and swimming velocity is partial correlation coefficients with clean swimming time of the respective laps as control variable. Spearman’s rho rank correlation coefficients for glide distance total for all turns with 5 m turn-in time.
