I read a lot of interesting things this week but much didn't really seem to fit into a blog post well. Here are three that I thought might be interesting for the blog.
I've long been a fan of the color blue. I think it shows in this site.
Well, maybe my next pair of sunglasses should have lenses that match my blue HillRunner.com gear.
The findings of this research suggest that exposure to the color blue improves performance of a muscular endurance based task. Such a simple and inexpensive performance enhancement warrants further investigation to explore different exercise modalities as well as effects of different colored lenses, and the mechanisms as to how color affects performance.
Red had no effect in this study.
I agree with the conclusion. Further study is warranted. Am I rushing out to buy a pair of sunglasses with blue lenses? Heck no. However, I will probably be in the market soon and will this cross my mind if a pair I'm considering has blue lenses? Along with the thought of how they would look with my HillRunner.com gear, sure.
Keep your arteries healthy
We all know the importance of being healthy. However, how could not being healthy affect our performance? There's a lot of question about that, though I've always believed being unhealthy should obviously not be good for your performance.
Well, here's some evidence of that.
Arterial health appears to be an important determinant of muscle oxygenation during exercise. In turn, the muscle oxygenation during exercise is strongly related to the V˙O2peak. Developing training modalities to prioritise arterial health outcomes may be a useful way of improving V˙O2peak in this population.
Now, this was sedentary middle-aged individuals (ages generally in the 50s). Maybe not a lot of carry over to highly active athletes in their 20s but why not? I'd love to see some studies on arterial health and how it affects well trained athletes at all ages.
Marathon battle of the sexes
Battle of the sexes. I love these. It's interesting in how many ways we can find women are smarter than men. If we check who slows more in the second half, what do you think the results will show?
Men slow more than women in marathons. D'oh!
The sex difference in pacing is robust. It may reflect sex differences in physiology, decision making, or both.
I have my suspicions. In my experience, it's the men who are far more likely to set unreasonable goals and refuse to give up on them until they begin walking at 20 miles. Women are more conservative in their goal setting and more willing to adjust their goals if unforeseen circumstances arise.
