Elitetrack: Sport Training & Conditioning

Read the Article here, and discuss it below.

I think there is a typo.  For the 2nd 20m it says 2.38 for NS, but in the graph it says 2.33 for NS…

The should have included a static stretch then dynamic warmup group.  It would probably be the same as the dynamic warmup/no stretch group.

ya, I would probably agree because it is likely that the dynamic warm up would wash out the negative effects of the static warm up.

I would love to see a study on static/dynamic warm up v. no static/dynamic warm up and maybe even v. physiotherapy/dynamic warmup.

The should have included a static stretch then dynamic warmup group.  It would probably be the same as the dynamic warmup/no stretch group.

Which would still beg the question of why one would bother doing it anyhow?

“Normal Dynamic Warmup” It sounded like they always used a normal dynamic warmup. Did they always strestch before a workout? If a group was taken from a team who always did a stretch before testing, and a group from the same team was not allowed to stretch before testing, who’s average time would be better? I think the group accustomed to stretching wouold do better.

Here’s the scenario since I was both a coach of the group and a researcher on the paper-
Everyone always did a dynamic warmup preceding the workouts. They almost always static stretched prior to practice using a 12 stretch 15-20 second hold routine. Everyone in the study was from the same group (jump / multis). In the study one group did do static stretching and the other did not.

Sorry if I’m being dense here…so everyone always did static stretching before practice even during the study?

They did static stretching every day other than on the study. On the days of the study only the stretching group stretched. This was actually very closely monitored and all the stretching was intensity and duration controlled. The length of hold on each stretch was greater than what they would have normally done in practice.

Here is a recent New York Times article that only affirms past studies on the detrimental affects of static stretching prior to races or workouts.  It states other studies have found a 30% decrease in force output after static stretching.  Its simply amazing that almost 1/3 of your power could be cut by this type of stretching.  http://www.nytimes.com/2008/11/02/sports/playmagazine/112pewarm.html?_r=1&oref=slogin

I don’t think you’re going to get a 30% output decrease.  Why do media & studies have to make such huge swimgs?  First static stretching is wonderful, then it decreases your power by 30%.  It probably decreases your output by a few percent over only a few minutes after stretching depending on stretch intensity.
