Broad Jumps 

 Under the head of broad jumps are in- 

 cluded the standing one, two and three; 

 the standing and running hop, 

 step, and jump; and the run- 

 ning broad jump. Broad 

 jumping is adapted to athletes 

 of all sizes, the most 

 essential factors be- 

 ing accurate 



start is made from one foot ; the other foot 

 and the arms swing forward and backward 

 in order to get an impetus. 



In the running hop, 

 step, and jump, there 

 should be a 

 fast run of 

 about 80 ft. 

 The hop 

 should not 



This style is more difficult than the other 

 two on account of the reverse twist 



Stepping and a very powerful spring. 

 To make the standing broad jump, stand 

 with the feet together, the large joints 

 (ball of the feet) just above the edge of the 

 block. Swing the arms forward up, then 

 downward and back as a preparatory ac- 

 tion. Then incline the body forward, flex 

 the thighs and legs at about right angles. 

 In the act of jumping, use all the force 

 possible in the forward arm swing and 

 back lift as well as the leg spring. In sailing 

 through the air raise legs and bend well 

 forward. Just as the feet strike the 



be high or there will be too much 

 strain on alighting and the step 

 and jump will be weak. Make the hop low, 

 and the step moderate, and put tremendous 

 effort in the high and broad jump. The 

 running broad jump rules govern this event. 

 In the running broad jump the greatest 

 factors are speed, a good take-off, and a 

 vigorous rising spring. Striding is impor- 

 tant and should be practiced much. To 

 help the stride place a mark about 20 ft. 

 from the block, another about 50 ft., and 

 the start at about 100 ft. Take a few long 

 breaths before starting the run, gradually 

 increase the speed to the finish and be sure 

 to strike the striding mark with the correct 

 foot. When near the 50-yd. 

 mark hold the breath 

 for the final effort. The

ground give an additional forward 

 bend and thrust of the arms to 

 maintain the balance. The angle of the 

 jumper's body as he leaves the block 

 will determine whether he will jump high 

 or low. The proper angle is not easy to 

 get from the sharp edge of the block. 

 In the standing hop, step and jump, the 



shorter than the 

 others and the front 

 half of the foot alone should be placed 

 upon the block. The run should not be 

 made too fast else it will be impossible to jump 

 high enough. The position of the striding 

 marks vary if there is a strong wind either 

 ahead or behind. If you overstep the block
