Friends, I know that skipping helps improve speed and I also do it. But HOW does it help improve speed? We stand in the SAME position and jump with the skipping rope. So how does it help improve speed?

if keep on skipping school, u will have to learn how to run fast and avoid beatings from your parents

your leg muscles get conditioned to making small, more explosive, short efforts, which is what is needed for badminton. also, as you get better, the time between each jump shortens, which, on court, translates to you being able to take more steps in the same amount of time.

A simple model of human muscle would be a contractile element (CE) in series with an elastic element (SEE).
The CE is what you control directly. You can tell it to contract (a concentric contraction), or tell it to resist as the muscle is lengthened (an eccentric contraction). Also, if for any of the above contractions the muscle moves so slowly that it isn't moving, that would be called an isometric contraction.
The SEE acts like a spring when the muscle is stretched. This explains why in an eccentric contraction, the muscle force can be much larger than in a concentric contraction. If you then perform a concentric after an eccentric, you get more force at the start of the movement. This concept is the basis of plyometric training.
Let's say that you have a movement where high speed is the priority. You want to use that plyometric effect because voluntary muscle contractions are much too slow for high speed movement. However, you don't want to waste time and energy doing long eccentric contractions either. The solution is to keep the CE at a constant length with an isometric contraction, while SEE absorbs all of the eccentric load to maximize the spring effect. This type of training is sometimes called reflexive firing isometrics (RFI).
How do you train them? Focus on fast contact times. When you skip rope quickly, your feet can't stay on the ground for long otherwise they'll be hit by the rope. However, the problem with skipping is that the ability of the arms to rotate the rope becomes the limiting factor, rather than the foot contact speed. So, an even better solution for developing agility would be to skip without a rope.

I actually don't find this. Do one foot skipping and this will quickly be negated. I also think skipping without a rope is not quite as beneficial, since it does notihng for coordination.
as well as short movements double/Triple skipping can also help for out and out power, since your calfs have to jump higher.
Skipping is also good for the Fingers and the wrist, especially if you use a heavy rope to skip with.
I find if I skip consistently my general agility and movement is much better.

One foot skipping isn't any faster, it's just more load. How fast can you spin a skipping rope? With a good rope, maybe 200-250 rpm?
How fast can you hop in place? Maybe a 4-6 Hz, which is equivalent to 240-360 rpm.

How about double skips or triple skips? Was watching the Zhao Jian Hwa vid on youtube and he was saying that these would help.
