Demographic characteristics of 161-km ultramarathon runners.
Despite considerable recent growth in ultramarathon running, little is known about the characteristics of the participants. This work documents demographic characteristics of 161-km ultramarathoners. Surveys were completed by 489 of 674 runners entered in two of the largest 161-km ultramarathons in North America in 2009. Respondents had a mean (± SD) age of 44.5 ± 9.8 years (range 20-72 years) ...
متن کاملFoot strike patterns of recreational and sub-elite runners in a long-distance road race.
Although the biomechanical properties of the various types of running foot strike (rearfoot, midfoot, and forefoot) have been studied extensively in the laboratory, only a few studies have attempted to quantify the frequency of running foot strike variants among runners in competitive road races. We classified the left and right foot strike patterns of 936 distance runners, most of whom would b...
متن کاملThe biochemistry of runners in a 1600 km ultramarathon.
OBJECTIVE To investigate biochemical changes related to muscle breakdown, hepatic damage, hyponatraemia, and a number of other variables in the serum of participants in a 1600 km ultramarathon run. METHODS Blood samples were obtained from nine participants (seven men, two women) in a 1600 km foot race before, after 4 and 11 days of running, and at the conclusion of the event. Samples were ana...
متن کاملEffects of training and anthropometric factors on marathon and 100 km ultramarathon race performance
BACKGROUND Marathon (42 km) and 100 km ultramarathon races are increasing in popularity. The aim of the present study was to investigate the potential associations of anthropometric and training variables with performance in these long-distance running competitions. METHODS Training and anthropometric data from a large cohort of marathoners and 100 km ultramarathoners provided the basis of th...
متن کاملDo non-elite older runners slow down more than younger runners in a 100 km ultra-marathon?
BACKGROUND This study investigated changes in normalised running speed as a proxy for effort distribution over segments in male elite and age group 100 km ultra-marathoners with the assumption that older runners would slow down more than younger runners. METHODS The annual ten fastest finishers (i.e. elite and age group runners) competing between 2000 and 2009 in the '100 km Lauf Biel' were i...
