How to measure the steps of long jump and high jump


Excellent athletes generally take 28-32 steps to run up (can reach the highest speed), and can determine the number of run-up steps according to their own speed ability characteristics. It is suggested to practice on the straight first, form a habit, and then practice on the board
There are mainly two kinds of step point measurement,
Standing start, athletes stand on the run-up sign full speed start, this way of run-up, step is more accurate, the disadvantage is easy to run stiff
Pre run start, the athletes stand 1-2 meters away from the run-up mark, and start the run-up with small jump. It is easier to run at the highest speed, and the body will not be stiff. The disadvantage is that the step is relatively inaccurate
The step point of Fosbury Flop adopts arc run-up. First, determine the take-off point about 30 cm outside the middle of the cross bar. First, walk 5 steps to the right, which is a point. Then walk 6 steps to the right, which is B point. Then walk 7 steps forward, which is C point. From c-b-a run-up, C-B run-up is linear, B-A run-up is arc run-up. After repeated practice, you can find your own step point
The pace and rhythm of long jump and high jump are very important. The point measured by the above method is not necessarily your exact starting jump or take-off point. The important thing is to practice repeatedly, adjust the position of the point repeatedly, find out your best point, and then measure again. The point of long jump can be measured with a tape measure or the step



Xiao Gang has been practicing high jump hard since the beginning of February this year. Every month's high jump performance is higher than that of the previous month


Set the score in February as X, and increase y every month
x+y=1.45
x+5y=1.53
The solution is x = 1.43, y = 0.02



Long jump in track and field
In the competition, an athlete moved forward and fell into the bunker. Because of the unstable center of gravity, his arm moved backward and sat in the bunker. Where should the athlete's performance be measured


Measure the nearest place to the springboard where he contacts the bunker
