A Single Gene Mutation May Have Helped Humans Become Optimal Long-Distance Runners
In novel study, mice engineered to lack the same gene run stronger, longer and with less fatigue
Graduate student Jonathan Okerblom and Ellen Breen, PhD "evaluated the exercise capacity of mice lacking the CMAH gene, and noted an increased performance during treadmill testing and after 15 days of voluntary wheel running," said Okerblom, the study’s first author. Breen added observations that the mice displayed greater resistance to fatigue, increased mitochondrial respiration and hind-limb muscle, with more capillaries to increase blood and oxygen supply.
