Elite male freestyle swimmers hip roll characteristics research

With the progress of modern information technology, the application of high-precision sensors and better algorithms in swimming wearable devices affects the process of scientific swimming. The development process of swimming wearable devices is gradual, which reflects the transformation of scientific theories into scientific and technological achievements. Wearable devices will continue to be optimized in terms of volume, weight, measurement accuracy, waterproof performance, and ergonomics, etc. It is the mission of swimming researchers to embrace and create new technologies, the hip rotation Angle of the slower swimmer is larger than that of the slower swimmer.
