Rules That Grovem All Broad and Standing Jumps
Each contestant has three jumps and the best five three more jumps. The best (not necessarily the last) jump is the con- testant's record. The nearest mark made by any part of the jumper's anatomy on the ground is measured at right angles to the near edge of the jumping block. This applies even though the jumper, in falling back, jumps out of the pit.
��line, or the line extended, or touches the ground in front of the take-oflf joist with any part of his foot, such a jump is not measured; but it is counted against the competitor as one jump. A line is drawn 6 ft. in front of the scratch line, to be known as the balk line, and stepping, or falling, over such line, or such line ex- tended, in any attempt, is counted as a "balk," and two successive balks are counted as a trial jump. The rules for the running high jump shall govern.
Training Hints
Take only 8 or lo jumps a day, three days a week, wearing sponge rubber in the heels. See that the pit is soft. Before each jump concentrate strongly
���In the running hop, step, and jtmip, there should be a fast run of about eighty feet. The hop should not be high or there will be too much strain on alighting and the step and jump will be weak
