An age old question that many people remain divided on through out the ages. So let me stage the question a little more. If you take the super flexible (big time yoga types, focusing on flexibility) on the far right and the Body builder types (focusing on strength alone, with reduced flexibility), putting all other people somewhere in between. Now, where on this scale would you suppose most injuries occur?
Some may think the yoga types, with their increased flexibility, would get injured more often due to lack of strength, unable to maintain stability in the joints. Others may take the other stance and say the Body builder types would be more injury prone. Their lack of flexibility means they would easily pull a muscle with a moderate stretch of the muscle. Well, good news is that you're BOTH RIGHT!! The majority of soft tissue injuries occur on either end of the spectrum!
For the super flexible, they experience in increased range of motion in the joints. Without strength training this increased range of motion can be prone to injury. These hyperflexible individuals tend to be prone to ligamentous injuries, not muscles. The bodybuilder typesare more prone to muscular injuries. The muscles are so tight, the natural range of motion of the joint is reduced, making these muscles easily strained when stretched.
The key is balance! Take gymnasts for example..... They work on both flexibility and strength equally. Not to say they are immune to injury, nobody is impervious to injury! In terms of injury prevention these are the type of athletes that are conditioned appropriately! Unfortunately for gymnasts, its not a sustainable lifestyle. I've heard numerous times former gymnasts complain how gymnastics messed them up! Correction, Gymnastics was great for your body, stopping gymnastics is what has messed you up. When gymnasts stop working out they keep the ligamentous flexibility but lose the muscular stability! So now they fall to the far end of the spectrum where injury occurs more often.
When starting a new workout regimen be sure to keep this information in mind. It's important to balance your workouts with flexibility and strength. Oh, almost forgot..... Don't forget to get adjusted periodically as well! HAHA...... Come on, cant say you're surprised? I'm a chiropractor after all!!
