If you have even the slightest knowledge of kinesiology(the science of movement), arthrokinematics (joints/bones in motion/fulcrums and leverage), and how the two interplay...and you have been around bodybuilders and athletes, you will know FOR A FACT that bodybuilders have extremely low neurological function. They train for one thing; and one thing only..to look beautiful. To look strong. Half of the time they are neither(opinion on the latter).
Bodybuilding is not a sport
Bodybuilding is non athletic
Bodybuilding is non functional
A bodybuilder would go down in a match..in any athletic endeavor. Their proprioceptive capabilities are extremely low (and extremely undertrained), and many of them train their bodies in isolation and in pre stabilized environments (where there is no Transverse abdominis activation - sheath like musculature that wraps around the spine and ribcage protecting the vertebrae and stabilizing it). Core is also what connects transfer of energy and force from one part of the body to another. A bodybuilder would throw a punch with the arm. A boxer would throw a punch that originates in the torque of the foot, travels up the body ....and the core is the medium for this energy....which shoots up and out the arm and fist in a powerful explosion. Let me think...who would win? I won't go into how this would translate onto say a battlefield, or a boxing ring, or what have you. But it's not good. Have you ever seen a pure bodybuilder try to play sports? They just look stupid, uncoordinated, and clumsy. It's a complete joke to watch. They neglect stabilization training and many times neglect core stabilization and mobility (the most important aspects of training the body) in the never ceasing mindless efforts to do one thing; add more mass. Mass for the sake of mass.
If there is one rule of fitness it is this: Learn to handle your bodyweight first, and then progress to more unstable environments with more weight. It's amazing how many people (bodybuilders and athletes) neglect the golden rule. That's right......that's why you hear bodybuilders whining about slipped discs, fused vertebrae, any number of injuries that occur when you try to do what you AREN'T prepared for. WTF did you think would happen when you tried to bench press 350 pounds because bodybuilding.com said to do so?!!??
Isolation exercises force the heads of musculature into unnaturally rounded tips (heads) and shorten/increase contractility between muscle fibers in a more or less permanent state. That's why when you look at a bodybuilder versus an athlete of any kind; note the more rounded, pudgy look of the bodybuilders physique, and note the more natural, longer musculature of the athlete. Another thing. How often do you see a bodybuilder doing dynamic flexibility warm ups or stretches? Yep. Exactly.
I watched this one guy (bodybuilder) run in a pick up game of basketball. He had to be nearly 6'5", an incredibly impressive build, and he was incredibly, incredibly strong (in certain, artificially stabilized environments). But guess what? He sucked on the court. It was awful to watch. Nobody passed the ball to him and he just took up space. What good is strength if it is not functional strength? You need to be able to handle that force across all planes - sagital, frontal, and transverse....all at once.
The way bodybuilders train is usually in one controlled plane of movement. You do the math.
This isn't even really breaking all of it. There are 3 kinds of muscle fibers.
Type 1 - aerobic (slow twitch)
Type 2a -anaerobic (fast twitch)
Type 2b -anaerobic (fast twitch)
The way boxers train, workout designs and periodicity are all designed to amp up and amplify existing type 2 muscle fibers in a way that a simple 5 set 10 rep program cannot come near. SPeed and power athletes train their power systems exclusively....it is what they DO.
These athletes will destroy you!!! leave them alone! have you ever seen Manny Pacquiao fight? He just looks like a normal guy with a shirt on.......but he could rip you in half.
The bigger they are, the harder they fall! *unless they have function - like some professional rugby players that train their mass to be functional. If one wants to fight you - run.
