If I had a dime for every time a non-runner asked me/told me about how running was going to be the ruin of my body someday, well, Bill Gates would have nothing on me. I’m sure you know of what I speak.
So here’s a new study that we can throw back at the naysayers when they chastise us: running marathons halts cellular “suicide.” Who knew cells commit suicide? But anyhow, a new study out of Rome determined that after running a marathon, runners’ cells were less likely to die off than those of non-runners.
The study took blood samples from amateur athletes as they finished a marathon. The samples showed elevated levels of a particular protein that may be involved in the prevention of cell death. These proteins play a key role in the maintenance of skeletal and cardiac muscle tissues and neurons, which helps explain the protective effects of exercise and calorie restriction for survival and aging.
So there you have it–proof positive that we’re doing something right. This all sounds pretty good to me. Here’s to long runs!
