"Study: Triathlons can pose deadly heart risks"

I was listening to the radio this morning and they brought up an article that had been published by the Associated Press entitled "Study: Triathlons can pose a deadly heart risks." After finding it on the internet, I read it, and personally I find it a little funny that they would even do a study on something like this. The premise of the article is that triathlons place added stress on the heart, most specifically the swimming portion which is done in cold lakes or rivers. Many of the people who get involved in triathlons are not frequent swimmers, but are doing the triathlon because it is for a charity. Also, there is the problem that anyone can sign up for a triathlon. The study found that the risk of sudden death during a triathlon is 15 out of a million. I feel that this number is pretty low considering how strenuous a triathlon actual is. People who sign up for a triathlon should know that there is an inherent risk associated with participating and should adequately prepare for the stress that will be placed on their bodies. All this study proves is, if you are going to participate in a triathlon, you should properly prepare for the task.
