Yahoo article: Tour de France cyclists’ hearts larger than average
In other news, they also seem to have less body fat and climb faster than average.
Even the article states that “athlete’s heart,” i.e. the idea that the heart, like any other muscle, develops with strenous use, has been well understood for eons. I suppose the article represents “news” in that the study is new, but I can’t help but think that the implicit point is supposed to connect to performance enhancing drugs, somehow. Just in case you didn’t get it, they point out at the end that drugs would make this effect more significant.
After yesterday’s ride, in which I coasted in last to practically every intersection the group came to in 45 miles, I was exhonerated of doing anything to enhance my performance, including such questionable tactics as training, watching what I eat, getting enough rest, or losing weight.
