(Analysis number 1)
Consider a human with a body weight of 100 kg. During the gait all the body
weight will be supported just by one of the legs. Being this a dynamic process, it is
acceptable to increase the initial static load by a factor of 2 (as it was observed in
the dynamic numerical examples presented in
Sect. 5.4.4
). Therefore, it is
assumed applied in just one leg a total load P = 2,000 N. Supposing that this total
load is supported by the leg muscles, a simple and expeditious calculus using a
hypothetic leg perimeter p = 0.50 m allows to obtain a hydrostatic pressure q =
50 kPa on the muscle tissue, which is not far from the value suggested in the
