Rollerski Safety Best Practices

Due to the start of the rollerski season, we are republishing this story to help promote best practices when rollerskiing on the open road. Making yourself visible while rollerskiing is a must.

Below...

Wednesday Workout: Cold Weather Resource for Insiders and Outsiders

If you find yourself this morning in a part of the world where it’s truly cold, we feel for you. If you get outside and ski today, say in the Midwest (we’re thinking of you Duluth), the snow might be sandpaper slow, but the upside, there will be no snow melt. The trail conditions will hold until the next banana belt puff of air blows through. Here at FasterSkier, we scanned the archives to bring...

What Studying Twins Can Tell Us About Fostering Motivation for Exercise

One of the biggest public health challenges worldwide is physical inactivity. As the World Health Organization a study of American Birkebeiner participants which found that participating in group-based exercise provided an important extra bit of motivation even for people who were quite self-motivated to exercise or train. Another piece of the picture was examined in Finland. There, researchers had the opportunity to use a study of twins to disentangle the genetic and environmental contributions to...

What Weird Heart Rate Monitor Numbers Mean (or Don’t) About Arrhythmias

Athletes engaging in big volumes of endurance exercise are at some increased risk of heart problems – compared to those who do moderate exercise. The level of that risk is under debate. At the same time, recreational athletes using heart rate monitors during their training will sometimes see numbers go up as high as 220 or 225 beats per minute (bpm). Such racing heartbeats are called tachycardia, and some of the possible underlying causes can...

How Do You Make a Top-10 Biathlete a Medalist? Find 12 Seconds, Somewhere

Biathlon is a notoriously variable sport: besides skiing, there’s the shooting aspect which can ruin a race in a matter of seconds. Sometimes an athlete like Lowell Bailey wins a World Championship for the first time after 15 seasons competing; sometimes the most reliable guy in the sport, Martin Fourcade, finishes 46th. It’s a wild world. Norwegian PhD student Øyvind Skattebo set out to quantify just how variable the sport is, and what amount of improvement...

What Predicts Nordic Combined Success? Study Finds Out

The study, led by Vegard Rasdal of the Norwegian University of Science and Technology and the Norwegian Olympic Sports Center, was recently published in the...

We’re Not Invincible: More Heart Arrhythmias in Endurance Athletes (Book Review)

When I heard that there was a new book coming out about heart arrhythmias in endurance athletes, I was interested. Several years ago, I read some of the research papers that the book’s authors refer to. One was a cohort study on participants in the Vasaloppet, the 90-kilometer ski marathon in Sweden. Those researchers found that skiers who competed in more Vasaloppets had more heart arrhythmias – as did those who finished the race the...

“I think if you’re a nordic skier in New England, you should definitely be alarmed.” “That’s one of the main take-homes: skiing is not going to disappear completely, but it will generally be higher [in elevation].” So says Cameron Wobus, a Bowdoin ski team alumnus and a researcher at Abt Associates, a global research firm. Wobus and colleagues based in Boulder, Colo., and Washington, D.C., recently published a study in Global Environmental Change assessing the...
