The purpose of this study was to investigate relationships between the breaststroke turn phase time and movement during the turn phase in male competitive swimmers. The participants were six male breaststroke swimmers. All subjects performed three 100 m breaststroke trials with a push start, and the trial with the shortest time was selected for analysis. The swimmers were filmed using four cameras, and kinematic variables during the turn phase were calculated using two-dimensional analysis. The total turn time was 8.96 ± 0.20 s, and the 5 m RTT was 5.60 ± 0.13 s. Significant negative correlations were found between total turn time and distance at the point of first kick (4.99 ± 0.88 m) (r = -0.818, p = 0.047). All variables demonstrating significant correlations with distance at the point of first kick were associated with the pullout phase, except for push-off horizontal velocity. This suggests that both the push-off horizontal velocity and the pullout phase following the open turn play crucial roles in the turn performance of elite swimmers.
