Athletes in Action

THE P L • V L (5) Fie. 9 pposite really shows why off, and all the single- action Vaulters, make the turn of the body seen com- mencing in Fig. 5 and completed in Fig. 8. If the b dy was all wed merely to swing straight through and then hot ver the bar v ith a vigorous arm-pull, the total height obtained would be equal to the pace of the swing, plus the pow r of the arm-pull. By turning ov r, however, in harmony with the swing and arm- pull, th single-a tion aulter is able t intr due a third fact r, ther by adding the c ntributi n f a lift, r push up, to the for e of th ther tw fact r . \Vith the pole perpendicular and close into th neck and having the arm well b nt at the lbow, as s en in •ig. , the vaulter i able, by extending his arms, to lift hi body v rtically as hi legs b gin to dr p. Thi acti n properly per£ rmcd, will add anything fr m six inches t a £ t t the height which th ath- lct i abl t cl ar. h verticallift is beingwell carri d ut in Fig. 9 pp sit . It will be s n from 'ig. 10 that, ne the b dy is rai cd well above the er ss-bar the arm do n t g ut to a full-arm ' ten ion.

With the landing in mind th re£ re, H ff casts ff first with the 1 ft hand and allows th hips and 1 gs t c ntinu th ntire turning m vement fr m right to left. The right hand, however, retains it grip up n the pole for the final effort.
