FRIDAY, Jan. 15, 2021( HealthDay News) What makes a marathoner great?New research study pinpoints the physical characteristics of top marathon joggers, as well as could assist others enhance their marathon performance.Elite male runner were asked to work on treadmills at a series of rates and likewise on an exterior track at a speed of 13.1 miles per hr, comparable to finishing a marathon in two hours.While the marathoners ran, scientists measured their heart rate, oxygen consumption and also levels of lactic acid in the blood, to determine effectiveness of oxygen use during exercise.The study also examined the marathoners’ running pressure, stride length as well as body composition.Only 7 of the 16 individuals accomplished a VO2 steady state( secure oxygen intake)
when going for the two-hour marathon rate. That highlights just how extremely difficult it is to complete a marathon in under two hours, the researchers said.Overall, the professional athletes maintained a VO2 of 67 milliliters per kilo of body weight per min( ml/kg/min) at just over 13 miles per hour, concerning two times as long as the average person can accomplish when working out at their maximum.Also, the marathoners ‘lactic acid threshold– the rate at which it accumulates in the body– happened at a very high fraction of their VO2 max.
Lactic acid is created by the body as it turns food into power during workout; in the muscles it belongs to fatigue.The research was published recently in the Journal of Applied Physiology. “These leading professional athletes have the best mix of physical attributes for the marathon: They have
an extremely high VO2 max; they are extremely affordable [
effective] when performing at submaximal speeds; and they can go for a high fraction of their VO2 max without accumulating lactate in their blood [making them really resistant to tiredness],” research writer Andrew Jones, from the College of Exeter in England, said in a journal news release.Further research of “strategies which make it possible for a higher mean oxidative metabolic price to be sustained and/or boost running economy will play a significant function in future enhancements in marathon performance, “the researchers wrote.More info The University of California, San Francisco offers suggestions for running a marathon.SOURCE: Journal of Applied Physiology, news release, Jan. 12, 2021 Robert Preidt Copyright © 2020 HealthDay.
