Because I think it’s bullshit.
People always say that, but to me it’s the same thing as the “Fighters shouldn’t run long distances” myth, or the “athletes succeed IN SPITE of their programs.”
Forgive me for possibly being dogmatic, but I think alot of things athletes have done for a long time have been done for a long time because, quite simply, they work.
I doubt you’re any more likely to get injured if you stretch before or after. I have, however, hurt myself when I wasn’t “warmed up”. Most times, stretching figures into that warming up. [/quote]
Work for what though? Stretching, either before or after exercise, DOES increase the length of the muscle, resulting in greater range of motion. THIS can be beneficial–hence why it became a part of the dogma in the first place. The people then take that idea and extrapolate it to "stretching is good for all of the muscles–they should all be flexible because flexibility is a good state to be in. People just threw stretching at the beginning because it is part of the warm-up and it feels good.
For years people lifted with belts because they thought it was better for you and reduced the likelihood of injury. And it probably does for the short term in the gym. Now numerous amounts of research shows that in the long term, it weakens the your abdominals, obliques, and pelvic girdle resulting in far more hernias outside of the gym.
Stretching has been shown to decrease strength (Cramer et al., 2004; Nelson et al., 2001; Behm et al., 2001; Fowles et al., 2000; Kokkonen et al., 1998) and power (Cornwell et al., 2001)
With that said, some studies have confounded these findings (e.g. Knudson et al., 2001), which show that shorter duration (30 sec.) stretching does not negatively impact the force production. A recent study (Zakas et al., 2006) compared the two methods–long duration versus short duration–and found that the short duration did not result in force production decrements, while long term did.
In any case, don’t blanket statement things like “I think it’s bullshit”. If a lot of smart trainers like Robertson, Cressey, Thibaudaeu, Boyle, and others are challenging it, and the scientific literature strongly is against the idea, it’s worth taking a look at the research and disputing the methodology if you really disagree.
Frankly, I’m a traditionalist myself, but if the research and trainers are arguing overwhelmingly against an idea, I’m going to abandon it.
