This was the reply I got from Powerposition. His advice is not to be taken lightly and if you don't understand something, I can explain it better. The basics he is talking about is flexability, speed and power, and isometric training.
The thing with improving vertical jump is that you have to hit it from two seperate angles. One angle is that you need to improve the total power production of the athlete, and the quickest way to do that is to incorporate bodyweight plyometrics. The other angle is the weight room. I am persoanlly not a big fan of the squat jump, the truth be known is that he would develop a bigger vertical jump from box jumps!
The athlete needs to start incorporating squats below parralle for sure, if the athlete is not getting into a deep high bar squat he will not develop the VMO which is essentail for developing powerful leg extension. So squats are a must, the second thing is that the athlete needs to spend some time working on sloe tempo eccentrics, with an aggresive concentric. Loading the muscles through a longer time under tension will pay off big time. There also must me a lot of attention placed on the development of the glutes,Hams and calves. They are more important then the quads. Another area that will increase his vertical is ankle flexability. The athlete will increase his vertical simply from improving his range of motion through the ankles and calves.
As far as the plyo's they will be essential in the development of power through the ability to produce greater force following a maximal eccentric at the moment of take off. So box jumps, quick hops and old school skipping rope are key. Finally there is one pre test secreat. If you want to get a couple of inches in the vert stretch the anatagonist of the movment which in this case would be the hip flexors, and that will turn on the jumping muscles and increase performace. |
