(HealthDay)\u2014What makes a marathoner great?\n <\/p>\n

New research pinpoints the physical attributes of top marathon runners, and could help others improve their marathon performance.<\/p>\n

Elite male distance runners were asked to run on treadmills at a range of speeds and also on an outdoor track at a speed of 13.1 miles per hour, comparable to completing a marathon in two hours.<\/p>\n

While the marathoners ran, researchers measured their heart rate, oxygen consumption and levels of lactic acid in the blood, to determine efficiency of oxygen use during exercise.<\/p>\n

The study also assessed the marathoners’ running force, stride length and body composition.<\/p>\n

Only seven of the 16 participants achieved a VO2 steady state (stable oxygen consumption) when running at the two-hour marathon pace. That highlights how extremely difficult it is to complete a marathon in under two hours, the researchers said.<\/p>\n

Overall, the athletes maintained a VO2 of 67 milliliters per kilogram of body weight per minute (ml\/kg\/min) at just over 13 mph, about twice as much as the average person can achieve when exercising at their maximum.<\/p>\n

Also, the marathoners’ lactic acid threshold\u2014the speed at which it builds up in the body\u2014occurred at a very high fraction of their VO2 max. Lactic acid is produced by the body as it turns food into energy during exercise; in the muscles it’s related to fatigue.<\/p>\n

The study was published recently in the Journal of App<\/a>lied Physiology<\/i>.<\/p>\n

“These top athletes have the perfect combination of physiological characteristics for the marathon: They have a very high VO2 max; they are very economical [efficient] when running at submaximal speeds; and they can run at a high fraction of their VO2 max without accumulating lactate in their blood [making them very resistant to fatigue],” study author Andrew Jones, from the University of Exeter in England, said in a journal news<\/a> release.<\/p>\n

Further research of “strategies which enable a higher mean oxidative metabolic rate to be sustained and\/or enhance running economy will play a significant role in future improvements in marathon performance,” the researchers wrote.\n <\/p>\n\n
