There are a number of proven methods that target the fast twitch muscle fibers (FTF’s). By following these guidelines you will ensure that your muscles are provided with the right stimulus to development your vertical jump.

    • In the weight room try to lift in excess of 60% of your 1RM.

Generally speaking, the heavier you lift the greater the recruitment of FTF’s.

The exception to this is if you are doing ballistic weighted exercises such as barbell jump squats. In these instances it is ok to use a lower % of your 1RM – see the next point.

    • Aim for maximum speed on all your movements.

Whether it is lifting a weight, skipping, jumping, bounding, or throwing, try and do it flat out. Short burst (10 seconds or less) of very high intensity work will cause the type of positive muscular adaptations you are after.

    • Train eccentrically.

Eccentric training refers to emphasizing the work done as you lower a weight or descend in a jump. For weighted work this would be done using bands to accelerate gravity, or using drop and catch motions such as reactive squats. For jumping exercises the eccentric portion is emphasized in movements such as the various types of depth jump and altitude landings (see next point).

    • Plyometrics.

Plyometrics involves the activation of the stretch-shorten reflexive response to create more powerful contractions. These contractions are primarily the domain of the fast twitch muscle fibers so doing this type of training will really stimulate those type II’s.

    • Contrast Load Training.

This is one of our favorite training techniques and real jump improver. To use contrast load training you might perform a very heavy set of squats, say 75-95% of your 1RM, rest 1-2 minutes, and then perform a lighter more explosive movement such as unweighted jump squats. The initial heavy set fires up a process known as potentiation that triggers higher recruitment of fast twitch fibers in the subsequent exercise.

    • Over-speed Training.

Overspeed training is where you add some form of assistance such as having a partner pull you along, using bands to pull you along, or simply running down a slight hill. This trains your body to move faster than it otherwise would have by forcibly recruiting the FTF’s for the extra speed, and it reinforces to your brain how to send those messages that fire up the FTF’s.

    • Mental Training.

If you have ever seen an Olympic lifter before a lift you will know what a psyche up is. This is part of mental training. Those lifters are essentially getting into a frame of mind that tells their bodies to literally fire up the fast twitch fibers. It works equally in your jumping and training. Spend 20 seconds before a jump mentally preparing for the effort and you will jump higher than if you just go and do it. Why does this work? Because the psyche up is a method of getting your brain ready to send the signals to the fast twitch muscles that they are about to do some maximum effort work.

Conclusion

In order to get the most out of your vertical jump training, you should try to follow those principles. A vertical jump is a powerful, type II muscle fiber based contraction that takes place in a split second. The most effective and efficient way to train therefore is to ensure you fully develop those fiber types. Anything else is just wasted time and energy.
