Q & A Explosion Training
August 21th 2009 |
"Hey J, I'm a personal trainer in Boston, I'm certified through the NSCA (CPT) and taking CSCS in April for 2nd time. If your interested I'd like to shoot you a couple of emails with a couple of questions if you don't mind me bouncing some ideas off of you, I'm just trying to work with about 4 people who are trying to do vertical jump programs, and I'm just curious as to what actually works and what doesn't work. If interested email me at mike.1283@****.com Thanks, I'm also on the NSCA forums a lot, and I'm emailing a handful of people from there"
Thanks for takin some of my questions, Training with resistance bands, and chains as a method of progressive resistance on exercises like squats, and bench are they improving strength and power output? I had always heard that they increase power because you are forced to overcome the resistance as it gets heavier near the top of the exercise but I had also recently read that using bands may actually slow you down because you are teaching your body to neurologically move slower. That was the only place I had ever heard it and it was definitely not a valid source but it definitely got me thinking.
In the same context with squat jumps, I had done them beofore using light weights, but recently was told not to them with any weight at all because it will slow you down and teach your body to jump lower, any thoughts would be great.
Answer:
The one thing you'll find out about speed and power training is that everything can and will be disputed by one source or another. Always remember not to get too wrapped up in theory again anything can be proven or disproved depending upon the control group and methods used to reach a conclusion. Example; Exercise: dead-lift, control group: basketball players, theory: proving that the dead-lift decreases vertical jump performance in "athletes" We all know that the dead-lift is great for improving vertical jump. But if I gear my research simply toward the biomechanical aspects of the movement as it correlates to a "game like" basketball situation then my conclusion will prove my initial hypothesis to be correct. Because the experiments involved were geared toward measuring time or acceleration to a fixed height. Say the height is 10' feet. Both athletes are 6'6", 210 pounds, with a standing reach of 9' Both 20 years of age, similar type 2 muscle fiber density and skill level.
Athlete #1 trains 4 weeks using different heavy dead-lift methods, Athlete #2 trains 4 weeks using light explosive short range of motion movements, quarter jump squats, half jump squats etc... When its time to test Athlete #1 must uses exaggerated jumping mechanics mimicking the biomechanics of a max attempt dead-lift. Athlete #2 uses a shot jumping movement with hands already above the shoulders mimicking the biomechanics used when jumping for a rebound.
Time measurement begins at first knee bend and ends when the hand touches the 10' target. Obviously because of the way the experiment was controlled the results for athlete #2 are going to be far superior to athlete #1 and therefore disproving that the dead-lift is good basketball players, volleyball players etc...
I release a book "The Dead-lift Misconception" explaining my theory, the book gains hype, many coaches and trainers hold the theory in the book as the gospel truth and suddenly we have a generation of athletes missing out on all the positive benefits of the dead-lift based upon controlled experiments.
When we talk about chains and resistance bands we are talking about very minimal progressive load increases. At the bottom of the movement there is very little to no resistance, that allows you to maximally accelerate into the movement and maintain or increase your speed of acceleration through the entire movement.
So the CNS is sending messages to the muscles to contract harder throughout the movement creating optimized pathways and a higher vertical jump.
Of course if you suddenly increase the weight of the chains to something that really slows down acceleration you'll be working a different type of strength and changing the focus of the CNS. But again this is not a bad thing if combined with a proper power training program. We can take an MPT method and follow the heavy chain squats directly with light jump squats, or weight vest/body weight box jumps and the results would be phenomenal (of course based upon the athlete) Same thing on the bench, max flat bench press using chains or bands, followed by explosive plyo push-ups or flat bench medicine ball explosions.
If you are training a basketball player, a football defensive back, a volleyball middle blocker top end or reactive power is going to be more important then overall power in most game situations. When a rebound is in the air, when an outside hitter is going up to spike the ball, or a football is thrown up to a reciever, the situation is going to be as the control group example. The target or goal is going to be at a fixed height for all competitors.
So again if the ball is at 10 feet my max touch is 10'6" and yours is 11' the fact that you can jump 6 inches higher then me means nothing if I can get to 10' faster then you.
So if I can create more top end power with shorter biomechanics I'm going to win in almost every time. This example holds true for fighters weather it be MMA, Olympic Tae Kwon Do etc... Because every athlete that you train will be different, theory and approach will change from athlete to athlete therefore be more concerned with case to case application and practice then set theory. As you go forward you'll develop your own style's and systems that are effective and that you know inside and out.
Neuroendocrine Response In this article I want to focus a
little on a neuroendocrine response, reaction times and how different
training approaches can effect these neurological factors. The term
neuroendocrine response may be a new term for many of you, but you have
all experienced its effects. Neuroendocrine response is any type of tense
action that causes the endocrine system to dump hormones (such as
adrenaline) into the bloodstream.
Question:
Right now in my own program I've been doing a lot of pistons, or I do them as SL Box squats, progressing to get lower and lower. I just wanted to double check though, when you say classic box squats are being done on a 3 - 3 - 1 and then speed box squats, I'm assuming the numbers are for the tempo of the exercise. The only other thing I wanted to check is the ROE is that Rate of explosiveness?
it is very possible to get anabolic effects with the products on the market today and correct micronutrient timing. These types of "diets" can be as simple as the one outlined in TVP or a complex 24 hour a day 7 day a week plan. Here I will just discuss what you need to maximize anabolism and minimize catabolism pre and post workout.
Catabolism!!! Its a dirty little word and a word that every athlete should avoid at all cost. I know a lot of you are thinking what is catabolism? and why should I avoid it? Well catabolism muscle loss, its a state in which your body reverts to when there are not enough resources available in the athletes body to support anabolism or muscle repair and growth.
