His food must be light, wholesome, muscle building, 'and likely to improve the nerve forces and staying powers without materially adding to the jumper's weight; for the light man runs far less risk of injuring himself thari does his heavier brother. The pole-jumper, in addition to the development of the lower limbs, of course including the perfection of springy feet, must possess a fine development of arms and of the muscles of the upper half of the trunk (see photographs of musculature of A. E. Flaxman, in Chap. XV). When crossing the bar, the athlete must hold himself in a horizontal position parallel to it. In this attitude he has to support himself practically by his clutch of the pole, and support his weight with the upper limbs; therefore a great feat of strength has to be accomplished by the muscles of the front of the chest and back, by which the arms are attached to the body.
