Some teachers and students from Ningbo University in Zhejiang have developed the "Unmarked Recognition and Analysis System for Competitive Swimming" to accurately capture the athletes' postures, moves and mobility trajectories in water, so that the coaches could customise the better training method for each swimmer.

This system has been adopted by the China (Zhejiang) National Swimming Team and the Zhejiang Para Swimming Team since last year, improving the training effect for Wang Shun, the Olympic champion and Yu Yiting, the national champion.
