Suggestion is that not only is the sun exposure a factor, but excessive intense exercise and its effect on the immune system may play a role, too.
It’s easy to forget the sunscreen when going out for those early runs, but I guess it can all add up. Thanks for the link

8 people seems like an awful small sample.

Read further. They saw 8 people. The study involved 210 marathoners and 210 controls.

Oops, my bad. But I wonder if all those studied were Austrians who would probably be very light skinned.
More sun, more skin cancer, makes sense but wouldn’t that be pretty obvious? But would the same risk apply to say Kenyans?
Also, nothing mentioned about how runners may be quite a bit healthier in other areas like heart disease or diabetes or just general quality of life at an older age.

I think they found the marathoners more susceptible despite the fact that the control group had lighter skin and hair color. The idea of a control group is to allow for such differences, I think, among other things.
Of course they didn’t mention those other benefits: the study was on skin cancer, not on the risks/benefits of a marathon lifestyle.
More sun, more skin cancer. Knew that.
Exactly how is this news?

I think the news is in this part “excessive intense exercise and its effect on the immune system may play a role, too”

Aren’t we cranky this morning?
“Sun exposure may not be the only risk factor that distance runners face. The authors write that although there is no question that regular exercise is important to good health, there is good evidence that high-intensity training and excessive exercise can lead to suppressed immune function.
“This is quite well established,” Dr. Ambros-Rudolph said. “Many alterations in immune cell function have been noted at the cellular level in marathon runners.
“For example, there is the association between excessive exercise and immunosuppression reflected in the increased incidence and severity of upper respiratory tract infections in marathon runners after races.”
The exact mechanism is unknown, but there is evidence that trauma sustained during extreme exercise can induce the release of cytokines, proteins that can stimulate the growth and activity of various immune cells and that may limit the ability of the immune system to fight potential cancers.”
Interesting. I won’t be showing this to Mrs. Last Tri (avid runner and cyclist) who just had basil cell carcinoma on her face.

Not to be flippant, but does that come from eating too much pesto?
Hope all goes well with her, and you caught it early.
Not cranky, just skeptical whenever a medical article is posted here.
This study is weak!
Can you tell us why you conclude this?
**This study is weak! **
But it does at least intuitevely make sense, no?
Many people run marathons with little athletic background, then train for 3 months and almost kill themselves in the race. That cannot be good for your body.
Now, if you look at someone who prepares for a marathon over the course of a few years, slowly building up, taking much needed rest/recovery days, having good nutrition, managing other stresses in their lives and getting adequate sleep, I think the results may be different. Howeveer, that’s not the way things usually work. We want things instantly, including fitness, and that’s where the problem lies, not in the fact that aerobic exercise is detrimental.
