Correlation between flexibility and strength(7 posts)

Our of curiousity is there a correlation between flexibility and strength? I know flexibility has a lot to do with muscle length but is there also another variable of how much the muscle pushes back. And as the stronger you get this resistance to pull the muscle from stretching any further becomes greater and greater.

I know myself I have always had good hamstring flexibility but have been lacking hamstring strength to a degree. So now that I'm building the strength through muscle recruitment I feel my flexibility is decreases even with good stretching so this is why I ask.

While there are many strength building exercises that tend to shorten muscles, there is no specific correlation between strength and flexibility.

bull ca ca...
muscle length has everything do do with strength..flexibility causes the muscle to lengthen as well as improve the connective tissues.. Too many aspects to list here, but ya outta do more research before you make a claim like that. No offense intended...

Strength training done with incorrect form will have a negative effect on flexiblity. Strength training properly done with good form through a full range of motion will increase flexibility. Full range of motion makes the muscle strong and flexible. Most professional level bodybuilders are actually pretty flexible athletes. It's the gym rats that go huge at the expense of form who have issues.

What about these excerises where full range of motion puts far more strain on the joints (squats), or is just impoosible due to the movement (deadlifts/olympic lifts)?

For squats you can actually use a fairly full range of motion. Lots of people claim you can't go below 90 degrees in a squat, but it isn't so. As long as you don't have any rotary movements of the knee occuring, you don't rest the back of the leg on the calf, and you don't bounce in the motion full squats are pretty safe. This also assumes you are healthy to begin with, and use a reasonable weight. Look at power lifting competitions, and you will see the competitors going 'convincingly low', or below 90 degrees. And that is with huge loads of weight! Done right there is nothing wrong with a squat below 90.

For deadlifts and Olympic lifts you may not go through a completely full range of motion for all the muscles invovlved. Auxillary exercises can help to make up for this along with a sensible flexibility training component to the program. I would say that people who are really experienced at these lifts do use more ROM than the inexperienced though. Look at a power clean for example. Most guys at the gym never really get a full extension of the hips for real power, and muscle the bar with the smaller muscles of the arms. Not real pretty. I would say though that those who only do competition style lifts do have some muscle imbalance due to their training, and that makes the auxillary lifts important. Look at a lot of powerlifters and you'll see anterior roll of the shoulders, and things like abnormal curvatures of the spine in some. Too much of only one thing isn't good, and mixing it up will help with ROM.
