Sports and Bio-Fluid Mechanics Be-Link Dr. O. Mochizuki It is necessary to review effective training methods based on physics in order to improve the performance of athletes. Since sports are played in air and water, the fluid dynamics contributes greatly to their performance improvement. Motion depends on the forces acting on it, so it is necessary to investigate what forces are acting and think about how you can improve your performance. For example, the development of automobiles is the same procedure. Investigating the performance of insects will also help develop new small robots. I will introduce the development of a new canoe that applies the functions of living things in a river.
