跳躍力測試一問!

normally, NBA player measure their verticl jump in two ways, but either way you will need to know 1 thing first.
The first thing you need to know is your stand still vertical reach, meaning standing still (with shoes) and with your hand straight up, how high you will reach without lifting (both feet on the ground). Then you can measure your vertical jump in 2 ways:

1. stand still jump - no running, just jump without any step. The difference will be your stand still vertical jump.

2. running jump - some ppl jump higher with 1-leg jump, some ppl jump with 2-leg jump, but jump anyway you want, does not matter how long or how steps you need for a running start. Just anyway you can jump as high as you can. The difference will be your running vertical jump.

that will be like your 彈跳力. it does not matter how tall you are, since you are measuring how high you jump off the ground.

其實係用約的吧,要測力學中的彈力
