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 کاملMuscle Cramping During a 161-km Ultramarathon: Comparison of Characteristics of Those With and Without Cramping
BACKGROUND This work sought to identify characteristics differing between those with and without muscle cramping during a 161-km ultramarathon. METHODS In this observational study, race participants underwent body weight measurements before, during, and after the race; completed a post-race questionnaire about muscle cramping and "near" cramping (controllable, not reaching full-blown cramping...
متن کاملThe effect of physiology and hydration beliefs on race behavior and postrace sodium in 161-km ultramarathon finishers.
PURPOSE To determine if beliefs about physiology and rehydration affect ultramarathon runners' hydration behaviors or if these beliefs increase the risk for exercise-associated hyponatremia (EAH). METHODS Participants of the 2011 161-km Western States Endurance Run completed a prerace questionnaire, prerace and postrace body-mass measurements, and postrace assessment of serum sodium ([Na⁺]). ...
متن کاملInfluence of temperature and performance level on pacing a 161 km trail ultramarathon.
BACKGROUND Even pacing has been recommended for optimal performances in running distances up to 100 km. Trail ultramarathons traverse varied terrain, which does not allow for even pacing. PURPOSE This study examined differences in how runners of various abilities paced their efforts in the Western States Endurance Run (WSER), a 161 km trail ultramarathon in North America, under hot vs cooler ...
