how to jump higher

Humans can't jump very high.

Basketball players can jump and touch the basket in the air largely because of their height.On average, a professional basketball player can only jump upwards by 60 to 70 centimeters. Ordinary people usually jump 30 centimeters high. If you want to jump higher, you have to use other things.

The run-up before blistering is useful.That's what high jumpers do, and the current world record is about 2.4 meters.However, this number is calculated from the ground.Because high jumpers are usually tall, their center of gravity is almost a meter off the ground, and they bow backwards when they step over the railing, so the center of gravity actually passes under the railing.To jump out of a height of 2.4 meters, they don't really need to raise their center of gravity by 2.4 meters.

To beat a high jumper, there are two options:

1. Participate in sports training from a young age until you become the world high jump champion.

2. Cheating.

The first method is undoubtedly admirable, but if you choose it, you shouldn't be reading this album.Let's talk about the second option.

There are so many ways to cheat in the high jump.You can lift a ladder to get over the bar, but that's probably not a "jump".You can wear the pogo sticks that extreme sports fans love, and if you're fit, you might be able to beat non-prop athlete.But when it comes to pure vertical height, athletes have actually come up with a better trick: pole vaulting.

In pole vaulting, the athlete runs first, inserts a bouncy pole into the ground in front of them, and bounces himself into the sky.By leaning against the pole, the height of the pole athlete's jump can be increased several times.

The physics used in pole vaulting is fun, and the height of the jump is actually far less related to the pole than you might think.The key is not how flexible the pole is, but how fast the athlete can run.A pole is nothing but a tool to change speed from forward to upward.In theory, instead of a pole, an athlete could jump onto a skateboard, follow a smooth, curved slope, and jump to nearly the same height.

We can estimate the extreme height of a pole vaulter using simple 2nd grade physics.A champion sprinter can run 100 meters in 10 seconds.If an object were to fly at this speed under Earth's gravity, a little math would tell us how high it would go.

Height=(speed^2)/(2*gravity acceleration)=5.10m

Because pole vaulters run first and then take off, their center of gravity is already above the ground, and this height will be added to the final result of the high jump.The center of gravity of a normal adult is almost at the stomach, which usually accounts for about 55% of the height.Men's pole vault world champion Renault ·Lavillenie's height is 1.77 meters, so his center of gravity will increase his score by 0.97 meters, and the predicted final result is 6.07 meters.

Are our forecasts realistic?The real world record is 6.16 meters.A quick estimate to achieve this level of accuracy is great!

Of course, if you show up in a high jump with a pole, you will be disqualified immediately.Although the referee will object, they probably won't stop you, especially if you're waving the stick as you approach him.
