On May 9 and 10, 2009, this year’s International Self-Transcendence 12+24 Hour Race will take place in Basle, Switzerland. Like every year the well-known endurance-athlete Dr. Beat Knechtle makes a new interesting study together with runners of this race. He explains “In runners, several different anthropometric parameters with an influence on performance have been described. Depending on the running distance, body mass, body height, BMI, body fat, total sum of skin-fold thickness, skin-fold thickness at the lower limb, length of legs and circumference of limbs are correlated with the running performance. These parameters have been investigated in runners up to the marathon distance and in multi-day runs. However, an association between these anthropometric parameters and the performance in a 12 and 24 hour run has not yet been investigated. We now intend to investigate whether anthropometric parameters such as body mass, body height, length of extremities and body fat have an influence on race performance in ultra-runners in a 12 and 24 hour. Therefore we need male and female participants for the following investigation immediately before the race: Determination of body mass, skin-fold thickness at 8 sites, circumference and length of limbs in order to calculate fat mass and skeletal muscle mass. These measurements are harmless, need less than 5 minutes and will be executed by two experienced investigators in the hours before the start of the race. So interested athletes are invited to contact me in order to get a form that can be completed before the race.” – If you are interested in running the 12 or 24 hour race in Basel, please contact the Sri Chinmoy Marathon Team as soon as possible. A few numbers are still available.
