Pulmonary dysfunction in ultramarathon runners.
To assess the effects of extreme exercise on lung function we measured maximal expiratory flow volume (MEFV) curves in fifteen runners (mean age, 35.3 years; range, 26-46) before and after an 80.6 to 100 km (50-62.2 mile) road race. Mean running time for 80.6 km was 7 hr, 42 min. Post-race testing showed significant decreases of 12.4 percent in forced vital capacity (FVC), 9.5 percent in forced...
متن کاملUltramarathon runners: nature or nurture?
Ultramarathon running is increasingly popular. An ultramarathon is defined as a running event involving distances longer than the length of a traditional marathon of 42.195 km. In ultramarathon races, ~80% of the finishers are men. Ultramarathoners are typically ~45 y old and achieve their fastest running times between 30 and 49 y for men, and between 30 and 54 y for women. Most probably, ultra...

متن کاملDemographic 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 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...
