Participation and performance trends in 100-km ultra-marathons worldwide.
The aims of the present study were to (1) investigate the participation trends for the origin of athletes competing in 100-km ultra-marathons and (2) determine the nationalities of athletes achieving the fastest 100-km race times worldwide. Race times and nationality from 112,283 athletes (15,204 women and 97,079 men) from 102 countries who completed a 100-km ultra-marathon worldwide between 19...
متن کاملAge group performances in 100 km and 100 miles ultra-marathons
Improved performance has been reported for master runners (i.e. athletes older than 40 years) in both single marathons and single ultra-marathons. This study investigated performance trends of age group ultra-marathoners competing in all 100 km and 100 miles races held worldwide between 1971 and 2013. Changes in running speeds across years were investigated for the annual ten fastest 5-year age...
متن کاملThe Effect of a 100-km Ultra-Marathon under Freezing Conditions on Selected Immunological and Hematological Parameters
Although moderate exercise is beneficial for the human body and its immune system, exhaustive ultra-endurance performance in cold conditions might be harmful. The aim of this study was to examine the effect of a 100-km ultra-marathon under cold conditions (temperatures from -1°C to +1°C) on selected immunological, biochemical and hematological parameters. Participants were 15 runners (12 men an...
متن کاملThree-dimensional spatial structures of solar wind turbulence from 10 000-km to 100-km scales
Using the four Cluster spacecraft, we have determined the three-dimensional wave-vector spectra of fluctuating magnetic fields in the solar wind. Three different solar wind intervals of Cluster data are investigated for this purpose, representing three different spatial scales: 10 000 km, 1000 km, and 100 km. The spectra are determined using the wave telescope technique (k-filtering technique) ...
متن کاملChanges in single skinfold thickness in 100 km ultramarathoners
BACKGROUND Changes in single skinfold thickness and body fat have been investigated in ultraswimmers and ultracyclists, but not in ultrarunners. The present study investigated the changes in single skinfold thickness during a 100 km ultramarathon. METHODS Firstly, we investigated associations between prerace preparation and prerace body composition and, secondly, changes in single skinfold th...
