Stretching yes or no? A poll

The University of Nevada has done some research on the effect of stretching before running. Google for articles or follow this link for one of them. In general the message is that static stretching has no use or even might weaken your muscles before an excersies. I myself, although I write about it on this blog, I usually stretch only after running and mostly just my lower calf muscles. I have published a poll on the right of this blog. As Dutch is the default language the button 'stemmen' means 'vote' and 'resultaten weergeven' means 'show results'. I will also post this poll on Running in Business at LinkedIn for more results.

Running a marathon indoor

If you want to avoid the cold try running a marathon indoor. Why they have chosen to run around an icerink? I don't know. Maybe to lower the contrast between indoor and outdoor?

Stretching: Gluteus Maximus a.k.a. butt

It has been somewhile ago that I addressed stretching in this blog. So today, to make it up, stretching the Gluteus Maximus or otherwise know as your butt!

One method is to lay on your back and pull your knee into your chest (see poststamp on the right). For me this method does not deliver the result I was looking for.
I prefer a bit more complicated method which works for mee. THe first couple of times I did this kind of stretching in noticed the next day that it worked every time I wanten tot get up from my chair or was walking up the stairs.

Here how you strethc your right butt, I expect you to figure out how you can do your left one....

• Sit down on the floor with both legs straight in front of you and a straigth back
• Placea your right foot on the left (outside) of your left knee and grab with your left hand just below your left knee. With this take care of passing your right leg, with your left arm on the right hand side (still with me?). Your elbow of your left arm will psuh your right knee to the left
• turn your upper body to the right place, if need be, your right hand behind you
• push your right knee to the left with your left arm you will feel the tension build in your gluteus maximus a.k.a. butt

Maybe it is a puzzle the first time around but for me it works. Maybe this picture will help. maybe the orange in the back ground hides it a little but he is not holding his leg with his hand but for the rest he shows perfectly how to stretch the left side

googling for this image I came across this method as well:
Just as an extra option to try although for me it doesn't work...

Headache after running: exertion headache

Headaches after running or exertion headache: Aparantly an interesting topic as it is the most read post on my Dutch blog. I found out it is not one of the blog translated so let me set this strainght today.
I wrote my first post on this topic in May 2007 when I forwarded a request from a trainer who wantend to learn from others experience on this topic. This today is my most read posting. In response to its popularity I added a second post.

In general you can bring back the cause of headache after running to three categories of causes.

1. Muscle tension: When running you virtually use all muscles of your body including those in the neck and shoulders. Some people pull up their shoulders or are tensed when they run for other reasons (f.e. stress at work). This tension will lead to pain and strain on the muscles. This pain can radiate into the head leading to headache. This strain can also lead to the build up lactic acid in the neck muscles (just as will happen with the build up in you leg muscles while running). This acid will dehydrate the brain(cells) causing tension on the meninges which casues the headache just like with an hangover. Other casues of pain (for example problems with the cervical vertebrae) can also lead to this kind headache. If you think it might be the strain of your neck muscles: try to relax while running, let your shoulders hang or do some relaxing exercises before of during the training.
2. Dehydration: When you run you loose water through perspiration. Of course you can compensate this for the large part by drinking during your exercise. You also loose electrolytes which are harder to replace. Both causes a disbalance of fluids in your brain and just like above this will cause a headache. Secondary: the loss of water can also result in a heat stroke / hyperthermia when it is no longer able to produce enough sweat to cool the body with perspiration. Here you can find advice on staying hydrated during running. And here the symptons and again some prevention tips of which the most important is, of course, drink!
3. Bloodvessels expanding en narrowing: When starting and exercise the boody widens the bloodvessels to enhance the transport of oxygen and nutriants to the working muscles. After the exercise the vessels narrow again. A good cooling down will slow down this process reducing the risk of a headache.
   "......a headache occurring after running or other similar exercise is more likely to be caused by the increased speed at which the blood is circulating..." [http://www.brainandspine.org.uk/]
   And if you already have a headache during the exercise and not just afterwards the sudden widening of vessels and increase of bloodflow might cause it so do a relaxed warming up so your body slowly can get used to the increased pace it has to addept to.

So I hope this helps as a start if you are looking for some answers on this topic. Otherwise just google around a bit more on exertion headache. It is always a good idea to consult an expert (doctor) preferable someone with understanding of running.

I like to read books on running. It is less tiring and jet you are busy with your sport. Just joking, nothing beats a good workout with training kilometers.
But I do like to understand how the 'mechanics' of running work. Something to doe with my background as a aerospace engineer?
On Complete Running Network a review of the book"Brain Training for Runners". First I thought it had something to do with a Nintendo game for on the road but it is something else.
From the review I learn it has to do with training the mind, focussing on the mental aspect of running. Training is not meant to strengthen your body but to strengthen your mind so that te body will follow. The review is positive but some of the reviews on amazon are more critical.
The reviews made me curious enough to read a view paragraphs on Amazon (it is a "look inside" title) and I might decide to order it for further reading.
