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.
Plus, two different studies look at how different types of muscle used in various athletic activities might inform training. In the first, static stretching is worse for cycling than running; in the second, think about small-muscle strength exercises.
STOCKHOLM, Sweden – Imagine if Charlotte Kalla or Marcus Hellner were caught this season with a positive test for EPO, or maybe a bag of blood in a hotel room. Or what if Ole Einar Bjørndalen showed up with HGH, or Petter Northug with steroids? If you can’t imagine any of these things, it’s because of a cultural change in Scandinavia in the last two or three decades that is the result largely of the...
FasterSkier is starting a once-a-month series looking at new research in the field of sports science. Periodically, we’ll flip through some of the world’s best peer-reviewed medical journals and summarize, in plain English, studies that we think will be of interest to skiers. Here’s our second installment; you can check out the first in a recent paper in the Scandinavian Journal of Medicine and Science in Sports. “The pathophysiology of the condition is poorly understood,...
This is the second of two pieces looking at the use of bronchodilating drugs to treat asthma in athletes – and their changing place on WADA’s prohibited list. available as PDF), the authors write that “Vigorous physical exercise can be followed by transient clinical signs and symptoms similar to an asthma attack and are due to post-exercise bronchoconstriction (i.e., a narrowing of the airways). Clinical symptoms include coughing, wheezing, shortness of breath, excessive mucus...
This is the first of two pieces looking at the use of bronchodilating drugs to treat asthma in athletes – and their changing place on WADA’s prohibited list. *** Asthma is far from uncommon in cross-country skiers: a 1994 study in Norway found that high-level skiers were about three times as likely to self-report as asthma patients compared to the normal population. A 1999 study by researchers in Norway, Sweden, and Nebraska found that even...
Yesterday three Blackjack skiers competed in the local high school running race, the Kootenay Kramp. The course, as described by LVR running coach Graema Marshall was “Gut busting and calf crushing hills, quad pounding paths, and mind testing ten...

It’s almost September, and let’s be honest, you’re in great shape. Or you’re almost there. Just a little longer distances, some slightly harder efforts and bam! You suddenly feel a tickle in your throat. Your head’s pounding, your legs are shot and your heart races when you start working out. You’re having trouble sleeping and this head cold is something you hadn’t bargained for. What gives? Probably overtraining. “Pish-posh,” you think. “I’m not an elite...
Canadian biathlete Brendan Green has had back problems before, but things came to a head in Oslo in February when he herniated a disc warming up for a World Cup race. It was a bittersweet weekend: Green finished 10th in the sprint, 13th in the pursuit, and then 9th in the mass start – the last with the herniated disc – but then faced excruciating pain that necessitated a harrowing trip back to Canada and...
“We have recently hypothesized that the optimal approach to altitude training would be to acclimatize to altitude, but train as close to sea level as possible thereby maximizing running speed and maintaining aerobic fitness,” Drs. Jim Stray-Gundersen and Benjamin Levine wrote in a landmark 1992 paper in the International Journal of Sports Medicine. The pair, who then worked at the University of Texas, were trying to answer the question of whether altitude training was truly...
“Give a Man a Fish and Feed Him for a Day. Teach a Man to Fish and Feed Him for a Life Time.” The common metric for the amount of cross-country ski training done in a year is the total number of hours spent training in the different intensity zones. One of the more vicious hazards of becoming pre-occupied with hours put in is missing or ignoring the hours NOT put in. These are...
Note: This is the third profile in a series about working out with high-performance athletes. The idea is to shed light on the daily routine of someone dedicated to training and share a regular Joe’s story of trying to keep up. LONDONDERRY, Vt. — As I pulled my vehicle up alongside Skyler Davis’ black Subaru in a grocery store parking lot, I wasn’t sure what to expect. I had seen him once before at this year’s...
When racers like Therese Johaug and Ivan Babikov reach the final day of the Tour de Ski, their bodies are already exhausted from day after day of racing. Their legs are tired, are they’re not alone: a recent study found that some aspects of heart function can not only decline, but remain suppressed after several days of consecutive races. But thanks to the human body’s remarkable ability to adapt to repeated stress, Johaug, Babikov, and...
(Author’s Note: While some of the athletes and coaches contacted by FasterSkier for this story were willing to openly discuss birth control, many wished to remain anonymous rather than allow the public to make assumptions about their sexual choices, a desire that FasterSkier respected. For these sources, pseudonyms will be marked with an asterisk (*) the first time they appear, and they will subsequently be referred to by first name, rather than last name like...
At Polish three time overall World Cup champion Justyna Kowalczyk has never been one to keep her mouth shut. Take, for example, her accusation that Marit Bjoergen’s asthma medicine is performance-enhancing. “Without the medicine Marit would not have won gold medals,” Kowalczyk said at the 2010 Olympics in Vancouver. If Bjoergen has asthma, then it may very well be true. But Kowalczyk’s implication was that either Bjoergen did not have asthma and was taking the...
Health problems related to smoke and pollution in the ski waxing rooms have attracted increased attention in recent years. Leading researchers in this field come from Sweden and Norway. Invited by Inggard Lereim, head of medical and anti-doping for the FIS Nordic World Ski Championships Oslo 2011, these researchers presented their latest results for doctors, head coaches and leaders of the team service teams in a special research seminar on the topic held in Holmenkollen...
Pete Phillips has a coaching resume that is one of the best in North America. He is currently the Head Nordic Coach at
Adam St.Pierre, M.S. is the head coach of the Boulder Nordic Junior Racing Team and an exercise physiologist with the Boulder Center for Sports Medicine. As we approach the heart of the XC ski racing season, it is important that athletes adjust their training to get into peak form for the year’s big races, whether they be World Championships, SuperTours, or local events. Peaking is what endurance athletes try to do just before their most...
