The association between anthropometric and training characteristics on an athlete’s performance has been investigated in swimmers, cyclists and runners, but not in inline skaters. The aim of this study was to investigate the relationship between anthropometry, pre race preparation and equipment in the finishers of the longest inline race in Europe, the ‘Inline One eleven’ over 111 km in Switzerland. Basic procedures. We investigated the association of anthropometry, training, and equipment variables with race times in 84 male ultra- endurance inline skaters using bi- and multivariate analysis. Main findings. In the multivariate analysis, percent body fat, duration per training unit, and personal best time in the ‘Inline One eleven’ was related to the race time for all finishers. Out of the 84 finishers, 58 had already finished an ‘Inline One eleven’ while 26 participated for the first time. Speed in training and the kind of skates worn were related to race times of the 26 inexperienced finishers. The inexperienced finishers skating with custom made skates were significantly faster with 229.1 (12.7) min compared to inexperienced finishers using ordinary skates finishing within 290.8 (35.4) min (p < 0.001). For experienced inliners, body mass, the sum of skin-folds and percent body fat correlated to race time. Conclusions. We assume that inexperienced athletes in ultra-endurance skating need time to gain the experience necessary in choosing the correct equipment and doing the training in order to successfully finish a long-distance inline race. Experienced inliners can only improve race performance in an ultra-endurance inline race such as the ‘Inline One eleven’ through a reduction of their body fat.

We tested a 36-year-old UM male runner before and after winning a 24-h marathon. The primary goal of the study was cardiovascular assessment. The athlete experienced right knee pain for the first time after 12 h of running (approximately 130 km), which intensified, affecting his performance. The competitors ran on a 1984 m rectangle-loop (950 42 m) in an atypical × clockwise fashion. The winner completed 516 rectangular corners. Right knee Magnetic Resonance Imaging (MRI) one day after the run showed general overload in addition to degenerative as well as specific features associated with “turning to the right”. Re-examination after three years revealed none of these findings. Different kinds of overloading of the right lower limb, including right knee pain, were indicated in 6 of 10 competitors from the top 20, including a woman who set the world record. The affected competitors suggested as cause for discomfort the shape of the loop and running direction.

  • Lake Placid, Our Small Mountain Community, Is a Special Place to Live, Work and Raise a Family
    The Uihlein – Ironman Sports Fund of Lake Placid Lake Placid, our small mountain community, is a special place to live, work and raise a family. Since the turn of the 20th century, Lake Placid has been known for summer sports, but around 1910 the village became the pioneer winter resort in the United States. This breeding ground for Olympic champions is the only community in the United States to have hosted two Olympic Winter Games. It is this history of nurturing sports and local athletes with national and international promise that inspired the establishment of the Uihlein-Ironman Sports Fund of Lake Placid. The History of Lake Placid Sports In 1932, as the United States was in the midst of the Great Depression, Lake Placid hosted t he III Olympic Wint er Games. It was Godfrey Dewey, son of Dr. Melvil Dewey, founder of the Lake Placid Club and the Dewey Decimal System, who successfully presented the village’s bid for the 1932 games to the International Olympic Committee. “Olympic is not a magic phrase for effortless prosperity,” Godfrey wrote. “It is rather the key to a unique opportunity to achieve by our own united community efforts.” The village did indeed unite, building an arena, bobsled run and improving the ski jumps, cross-country-ski trails and speed-skating oval. The people of the community took a significant financial and volunteer role in the success of the games. Hometown hero Jack Shea was a double gold medallist in speed skating, one of many in a long line of Olympic-caliber athletes from this region.

    © Journal of Sports Science and Medicine (2004) 3, 167-173 http://www.jssm.org Research article CHANGES IN RUNNING SPEEDS IN A 100 KM ULTRA- MARATHON RACE Mike I. Lambert , Jonathan P. Dugas, Mark C. Kirkman, Gaonyadiwe G. Mokone and Miriam R. Waldeck MRC/UCT Research Unit for Exercise Science and Sports Medicine, Department of Human Biology,Faculty of Health Sciences, University of Cape Town, South Africa Received: 09 March 2004 / Accepted: 01 July 2004 / Published (online): 01 September 2004 ABSTRACT The purpose of this study was to determine if runners who completed a 100 km ultramarathon race in the fastest times changed their running speeds differently compared to those runners who ran an overall slower race. Times were taken from the race results of the 1995 100 km IAU World Challenge in Winschoten, Netherlands. Race times and 10 km split times were analyzed. Runners (n = 67) were divided into groups of ten with the last group consisting of seven runners. The mean running speed for each 10 km segment was calculated using each runner’s 10 km split times. Mean running speed was calculated using each runner’s race time. The first 10 km split time was normalized to 100, with all subsequent times adjusted accordingly. The mean running speed for each group at each 10 km split was then calculated. The faster runners started at a faster running speed, finished the race within 15 % of their starting speed, and maintained their starting speed for longer (approximately 50 km) before slowing. The slower runners showed a greater percentage decrease in their mean running speed, and were unable to maintain their initial pace for as long.

  • Mastering Science of the Slide Crucial to Success of Every Winter Olympian by IVAN SEMENIUK
    Mastering science of the slide crucial to success of every winter Olympian By IVAN SEMENIUK Think about it: Every sport at the Winter Olympics relies on some kind of man‐made object sliding over ice or snow. As Ivan Semeniuk writes, winning isn't just about the athletes, but also the scientists – mastering equipment design by understanding the frictional forces at work Watch a group of children in a schoolyard as they take running leaps onto a bare patch of ice and you know you're witnessing a kind of joy that's been around a long, long time. Our fascination with ice and its slippery nature may date back to the depths of the Pleistocene, when the first Homo sapiens left Africa and pushed northward into the glacier‐bound world beyond. During the course of that epic journey, someone had to have been the first to see the latent fun in a frozen pond or a snow‐covered hill. Fast forward a few hundred thousands years and the 2014 Winter Games are set to begin. Like its summer counterpart, the quadrennial event is humanity's most recognized expression of the athletic ideal. But it's also an acknowledgment that the coolest thing about winter is that we've invented so many ways to play with frozen water. One way or another, every competition in Sochi will come down to some kind of man‐made object sliding over ice or snow – an almost magical phenomenon that makes the winter sports we love possible. And like every love affair, it comes with an element of mystery.
