Run on Soft Surfaces?

Many people will tell you that you should run on soft surfaces like dirt and grass to decrease the shock your body absorbs when running.  It’s been shown that stress fracture are a repetative stress type injury so reason would say that avoiding unforgiving surfaces should reduce the chance of a stress fracture.  Maybe it does.  Maybe it doesn’t.

10% My Ass

The 10% rule is widely repeated in running communities.  It says that, to avoid injury, you should increase your mileage by no more than 10% each week.  It seems reasonable if maybe a bit conservative.  Apparently some people have looked to see if there is any truth to this rule of thumb.  They say no.

Hype Cycle

The history of drinking during endurance exercise is an interesting one. It serves as a wonderful lesson for two reasons. First, it demonstrates a concept I’ve discussed at length before called the Hype cycle where a particular concept or method goes through a cycle of first overemphasis, then under emphasis, before eventually settling into its rightful place. This cycle can be seen almost anywhere, but in terms of training you’ve seen it with such things as “core” training, mileage, and interval training.

Science of Running Blog

Though long I really like the blog post linked to above.  I don’t really care about the information about hydration but really the hype cycle.  The author shows how hydration has gone through the hype cycle.  It is explained better in the link above but the basic idea is that new evidence is almost always overemphasized before a more realistic middle ground is adopted.

I have a feeling the barefoot running trend/craze is in the overemphasis phase of a hype cycle.

Health Markers

Many runners feel somewhat invincible.  I’ve certainly felt that way.  I’ve gone to the doctor and they rave about how good my blood work is and urge me to keep doing what I’m doing.  One doctor even told me he gets tired of seeing unhealthy people that ask “how do I fix it” when he feels the answer is “it’s too late.”  For the record, I disagree with his opinion there.  The body seems to be incredible with adaptation and change …  but then I’m not a doctor.

Runners tend to have high levels of HDL which is why doctors, like mine, rave about our blood work.  But having high levels of HDL doesn’t necessarily mean you aren’t at risk for heart disease.
