Look at these two exceptional long-distance swimmers, Johannes Liebmann and Zalan Sarkany, in slow motion during the historic 14:26.79 World Record race.
You can clearly see that their techniques are very different - hand entry, catch setup, shoulder and hip rotation, kicking, and body position.
You can also see that even within the same swimmer, some elements of technique vary from stroke to stroke.
Of course, you can measure all kinds of angles - body, hip and head rotation, elbow position, body alignment, and more. But there are two fundamental challenges:
1. You need to measure these variables stroke by stroke.
2. Even then, they don't tell you how efficient each individual stroke actually was.
And there is another important point: there is no single “perfect” technique. The optimal technique is highly individual and depends on the swimmer.
This is where MySwimEdge takes a different approach.
We measure stroke-by-stroke efficiency - including distance per stroke (DPS), average speed for every stroke, and stroke-to-stroke variability.
Then you can use video to compare the best and worst strokes and identify where there is potential for improvement.
Because intra-cycle velocity shows how effectively the swimmer moves through each stroke cycle - not simply what the technique looks like at a particular moment.
