[Evaluation of the degree of human physical fitness by the energetically optimal walking speed].

This paper describes methods for evaluating energy expenditures associated with terrain cure walking under the assumption of additivity of expenditures involved in walking along flat and rugged terrain. It has been shown that people of different physical fitness have different values of energetically optimal walking speed. The concept of the energetically optimal speed allows quantitative estimations of movement associated energy expenditures, taking into account individual exercise tolerance.
