Scientific Works by Beat Knechtle

Beat Knechtle, born in 1964, is a Swiss medical doctor and scientist competing in ultra triathlons since 1997. Due to his interest in physiology and due to his habilitation thesis he started soon after the first long-distance races with field studies regarding exercise and fluid metabolism. Until today he has finished more than 80 ultra triathlons and published more than 700 research articles... and that's not the end. Studies concerning ultra triathlons, you'll find below.
