Under the water, it can be difficult to see every kick and every stroke a swimmer makes. But Manhattan Mocap did just that with Olympic swimmer Dana Vollmer to analyze her butterfly stroke and underwater dolphin kick.
Manhattan Mocap worked together with the New York Times and the NYU Movement Lab to film Vollmer and create models of her strokes to analyze how the body and water move together. Findings can help coaches instruct swimmers in how to move better in the water to gain speed. A motion capture session might help a swimmer learn where their strokes go wrong, and how to correct them.
Swimsuit manufacturers and other providers of pool and swimming gear can also use the modeling animations to study how different materials, textures and cuts of fabric might behave under water.
