Asking the best technique ie. how much the knees should be bent
There are lots more on Yahoo answers. Just go to the site and search for how to jump higher or vertical leap or jump higher. If you cannot find what you are looking for, just ask about it. Who knows, you may find an answer that best suits you.
Safety is one of the most important things which should be considered when doing exercises. Many injuries occur as a result of wrong exercises or just due to lack of attention. While doing exercises for improving vertical leap you will face some injury or the other. When you don't know how to jump higher correctly then it will be a problem. A simple thing that you can do is exercise in slow motion to get all the things correctly. Then gradually increase the intensity when you can do the exercise correctly. Many a times people just start with complete power but this will eventually go down and there will be no improvement. Do you want this to happen to you? I will certainly not wish for such thing.
The common complaints of people trying to jump higher are some sort of pain in the
toes
ankles
knees
calf muscles
back
shin
These problems can and should be avoided so that you do not injure yourself badly. Some of the things that you can do to avoid unnecessary problems are
1) Do not do workouts like crazy. Keep a limit according to your body's strength.
2) The moment you feel some pain in any part of the body, you should stop and see whether the injury is small or big.
3) There are some reports that using ankle weights will cause damage to the foot. So better to avoid it.
4) Do the exercises in a good open place.
5) Don't do awkward jumps. Many teens will try some stupid things and the only thing they do is injure themselves. Trust me you dont want this.
6) Do not push beyond limits.
7) Work on the whole body and not just one or two parts.
8) Last but not the least, take adequate rest to rejuvinate yourself.
This is a short video where Micheal Jordan is answering the question "How can I jump higher?"
Here is what he says
"I really don't understand the physics of jumping and how you increase that. The things that I can say that I did when I was a kid to improve my jumping, very basic things, I used to work on jump, I used to just try to jump and try to dunk and I guess if you exercise that muscle to that activity some how its gonna improve. How much it would improve? No one can really dictate who is gonna be the greatest leap of all time.....
After reading about the static and dynamic warmup in the last post, let us now see some videos showing warmup moves. Seeing someone do it is far better than reading about it. Here are 8 videos which will help you.
Before starting any rigorous exercise you should do a warmup for about 10 min which will help to stretch the major muscles. A good warm up will prepare you for the specific exercises that follow. Here, as you want to do exercises which help to jump higher, so warming up the legs is most important.
After doing a warmup you should feel flexible with heart pumping faster and the temperature of your body should increase.
There are two types of warmups, one is static and the other is dynamic. In static, as the name suggests, you will do exercises standing on one place whereas in dynamic warmup, simple movements are done to prepare for the real exercise.
Which is better - Static or Dynamic?
"A study [7] compared the effect of dynamic warm up (DWU) with static-stretching warm up (SWU) on power and agility. Subjects aged 18-24 years performed one of the two warm up routines (DWU or SWU) or performed no warm up (NWU) on 3 consecutive days with the process lasting 10-minutes in each case.
After 1-2 minutes of recovery, subjects performed 3 tests of power or agility i.e. T-shuttle run, underhand medicine ball throw for distance and a 5-step jump. Repeated measures revealed better performance scores after the DWU for the three performance tests relative to SWU and NWU. There were no significant differences between the SWU and NWU for the medicine ball throw and the T-shuttle run, but the SWU was associated with better scores on the 5-step jump. The authors concluded that because the results of this study indicate a relative performance enhancement with the DWU, the utility of warm up routines that use static stretching as a stand-alone activity should be reassessed.
It would be interesting to see this experiment repeated following a general warm-up process in all cases since this may be more analogous to many sports situations."
