Each frame is .1 seconds apart. Oussama Melloulli's time for this event was 14:37.28. In this sequence, the swimmer is kicking more vigorously than in earlier stages of the race. It appears that his kicking increased over the last 100 m of the event. This is a left-side breathing stroke.

This stroke analysis includes a moving sequence in real time, a moving sequence where each frame is displayed for .5 of a second, and still frames.

Notable Features

 

How much breathing to the left extended the right-side inertial lag can only be estimated. But, compared to the left side pull, which began very soon after the right arm finished propulsion, it probably played a considerable role. As has been seen with most male distance swimmers, the skill of breathing quickly with minimal resistance is an action that needs to be revived.

It is no wonder that male distance swimming records are not improving. So much time is spent in inertial lags in top swimmers. When a swimmer emerges and applies force more consistently, the next drop in distance swimming records for men is likely to occur.
