A study published Tuesday is getting a lot of press for showing that cross-country skiers are at a higher risk of heart arrhythmias, and are more likely to have one the more Vasaloppets they complete and the faster they race them. When the data was first publicized two years ago, we asked – what are these things called arrhythmias, and why might skiers be having so many?
This month, the Journal of Applied physiology confronted allegations of scientific misconduct in two cases: one when a study used an athlete who turned out to have been doping, and another when researchers asked participants to use banned methods. The journal invited discussion from many of the scientists involved as well as WADA, with interesting, and antagonistic, results.
Nordic sports are pretty egalitarian, as far as athletics go – but women are still confronted, constantly, with stereotypes about what is and is not appropriate or possible for them to do. In southern France, two researchers are focusing on what effects these stereotypes have on women’s participation and performance in a wide range of sports, and explained their findings in an interview.
There’s a correlation between the use of nutritional supplements and the willingness to dope; but why, and how? Does one cause the other? Plus, quick reads on whether caffeine improves ski performance (hint: it does!) and if minimalist footwear really helps approximate the mechanics of barefoot running.
Scientists have identified a handful of genes that control roughly a quarter of the variation in how people respond to endurance training. What does that mean for athletes – will we now be able to predict who might win a gold medal? FasterSkier talked to one of the researchers, Dr. Carl Johan Sundberg, to find out.
