An extended, swinging step, without haste and without unduly taxing the lungs, is advantageous in all movements. When accustomed to this pace on the drill ground, the men will march with practically the same step on varied ground, and this appears more desirable than to shorten the step, while at the same time increasing the distance to be covered in a given time. The length of the pace depends largely upon the height of the individual, but even small men can maintain a step of 0.80 m. without undue exertion.[71] In Switzerland the cadence has been fixed at 116-120 steps per minute “with a view of suiting the peculiarities and the varying degree of mobility which characterize the inhabitants of the different cantons.”(!) For purely practical reasons it is advisable to fix upon some even number of paces in order that the cadence may be tested with the watch. (Austria excepted). The longest pace in conjunction with the highest cadence (_Bersaglieri_, whose march is almost a double time, excepted) is found in England and Switzerland. Such a performance could not be kept up by a fully equipped man without impairing health. [71] When the leg is extended at an angle of 57 degrees the length of pace would be as follows: Height of man. Length of leg. Length of foot. Length of pace. 1.6 m. 0.8 m. 0.24 m. = 0.75 m. 1.675 „ 0.857 „ 0.253 „ = 0.776 „ 1.70 „ 0.87 „ 0.26 „ = 0.80 „ 1.75 „ 0.88 „ 0.26 „ = 0.82 „
