do not finish the jump, since it will not 

 count anyhow. In soaring through the air

 before alighting extend the legs well forward 



jumper may, however, raise and lower his 

 heels as often as he likes preparatory to 

 jumping. In the two and three broad 

 jumps there must be no stops 

 between the jumps. For the 

 running broad jump, and 

 hop, step and jump there is 

 no limit to the run.

The angle of the body in leaving the block will 

 determine whether the jump will be high or low 



to gain every inch. On alighting jab the 

 feet downward to avoid sliding. It is not 

 good form to alight sideways, because there 

 is greater danger of falling back or of turn- 

 ing an ankle. In case you fall backward 

 hop back a few inches rather than fall flat. 



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 



When starting for a standing jump, if 

 the foot of the jumper leaves the block 

 more than once, or slides forward, it counts 

 as a trial jump, but is not measured. The 



upon it. To get height in jumping place an 

 obstacle in the pit 3 ft. high, 8 ft. from the 

 block. Train as for sprinting.
