スポーツにおけるパワの評価 : 水泳を例として(水泳)

概要

The word, "power" is used both in engineering and in human daily life. The definitions or meanings are, however, different from each other. Think a tug of war in deadlock as an example. Power is zero in engineering, even man gets tired. Since sport engineering aims at applying engineering (in most cases mechanics) to human behavior, the definition of power, inner product of force and velocity, is not appropriate. Another definition of power, "physiological power", was proposed to bridge the gap between two meanings of "power". This definition accounts for the above-stated case; a tug of war in deadlock. Its examples to swimming were also included, and the differences between "mechanical power" and "physiological power" are investigated.
