IOC84: Racing dogs at Iditarod, Alaska 2014

A special expertise of the OROBOROS mitoscience-team is the logistic planning and support of expeditions with a focus on mitochondrial physiology. IOC84 was integrated in the Alasca expedition as a training course. >> IOC84

• Collaboration of Michael Davis and Katherine Williamson (Comparative Exercise Physiology Laboratory, Oklahoma State University) with Martin Buser (Happy Trails Kennel, Alaska), Robert Boushel (Swedish School of Sport and Health Sciences, Stockholm, SE), Benjamin F. Miller and Karyn Hamilton (Colorado State University, US), and Erich Gnaiger and Verena Laner (Medical University of Innsbruck and OROBOROS INSTRUMENTS) - a Power-O2k project with six OROBOROS O2k.

Alaska Expedition pre-study ("Iditarod"). Collaboration with Michael Davis (Oklahoma State University, US), Robert Boushel (Swedish School of Sport and Health Sciences, Stockholm, SE) and Benjamin F. Miller (Colorado State University, US) - with integrated IOC84 (Jan 04-07).

Dr. Erich Gnaiger (Medical University of Innsbruck and OROBOROS INSTRUMENTS) and his collaborator Verena Laner (OROBOROS INSTRUMENTS) joined the project of Michael Davis (Oklahoma State University) in Big Lake, Alaska. Cumulative training effects on the mitochondrial function of alaskan sled dogs were studied in January and March 2014 at Happy Trails Kennel in Big Lake, Alaska. Further participants were Robert Boushel (Institute for Sport and Health Sciences, Stockholm, SE) as well as Benjamin F. Miller and Karyn Hamilton (Colorado State University, Fort Collins, US).

Racing dogs at Iditarod, Alaska 2014

Iditarod - The last great race(r) 2014: the greatest challenge up to the finish: » iditarod.com

At Martin Buser's 'Happy Trails Kennel' (Big Lake, near Anchorage, Alaska) Prof. Michael Davis (Comparative Exercise Physiology Laboratory, Oklahoma State University, USA) conducts a long-term collaboration with Martin's team to study and train the Alaskan dogs in preparation of long-distance races, the most challenging of which is the 1,100 mile Iditarod race. Martin Buser is 4 times champion of the Iditarod, with a scientifically oriented interest in the study of the genetics and physiology of the dogs that goes far beyond the race.

The line of mixed-breed Alaskan huskies of Martin incorporates sprint-dog lines and is selected and trained as much for long-distance endurance as for speed - and happiness. "Happy dogs perform better and make racing more fun" (Martin Buser).

In January and March 2014, Mike Davis and Katherine Williamson teamed up with Erich Gnaiger and Verena Laner (Medical University of Innsbruck and OROBOROS INSTRUMENTS), Robert Boushel (Swedish School of Sport and Health Sciences, Stockholm, SE), and Benjamin F. Miller and Karyn Hamilton (Colorado State University, US) to focus on mitochondrial respiratory function in the skeletal muscle of the dogs. With a Power-O2k approach using six OROBOROS O2k, these mitochondrial studies are conducted at the beginning of the intensive training period and after the Iditarod race, considered as the final stage of the most intensive endurance training.

• k300: Congratulations to Rohn Buser for winning this race. "Rohn won it in 38 h and change, but not without a MAJOR challenge from Jeff King who made a run at Rohn in the last 5-10 miles, but couldn't overtake him. 300 miles (500 km) in 38 h. When you subtract the 10 h of mandatory rest, that means Rohn's dogs AVERAGED nearly 18 kph for over a day. These are the dogs we will investigate in March. That isn't even the race record. Ironically, the race record of 37 h 4 min is held by Martin Buser" (Michael S. Davis, 2014-01-20).
