Here is a link to a question about improving quickness from the University of Nebraska.
quicknessHusker Power uses slightly different terminology. They describe it as training triple extension, which is referring to extension of the ankle, knee, and hip. Triple extension is done in most explosive movements, like sprinting.
I know that most Div 1 schools still do cleans for their baseball players. My last couple years coaching the Huskers baseball team we quit racking our cleans and just did clean jumps or jump squats instead. We were trying to limit using so much upper traps trying to keep our shoulders in better position while still training the triple extension. They have been working with a physical therapist named Ron Hruska (http://www.posturalrestoration.com/hruska/index.html) on developing programs for baseball players. I've seen this guy work and he is amazing and would suggest everyone interested to get on to his websites
www.posturalrestoration.com and
www.hruskaclinic.com and read some of his articles.
The situation of Husker baseball strength training is very unique. Mike Arthur has been a strength coach at Nebraska for something like 20-25 years. He has been awarded National Strength Coach of the Year while he was assisting Boyd Epley. The thing that makes the situation unique is that he hasn't worked a lot with baseball until recently. Its cool because he can analyze the sport of baseball without all the preconceived thoughts about baseball strength training that have been passed down by uneducated coaches in the past. He is an excellent researcher as well as a former competitive strength athlete. If you get a chance to hear him speak you will be very impressed with his knowledge about strength training. It was a great experience for me coming from a college baseball background and working with him while he was doing his baseball analysis from scratch.
