Researchers from University of Tsukuba investigated the propulsion mechanism by visualizing water flow around a swimmer during underwater dolphin-kick swimming in a water channel via particle image ...

Tsukuba, Japan—In competitive swimming, both upper- and lower‑limb motions play important roles in propulsion. Extensive research has focused on the dolphin kick used in the butterfly stroke, ...

Researchers at University of Tsukuba have identified two fundamental coordination patterns underlying the underwater dolphin kick in swimmers: (1) the coordinated motion of the shank and foot and (2) ...

Researchers investigated the propulsion mechanism by visualizing water flow around a swimmer during underwater dolphin-kick swimming in a water channel via particle image velocimetry. Their findings ...

Tsukuba, Japan—The swimming motion imparts momentum to water, a fluid, thereby generating a propulsive force. Thus, we can understand the propulsion mechanism by examining the water flow generated by ...
