Older athletes may never beat 20-year-olds in a 100-meter sprint, but a new, small study suggests that, in at least one way, they are just as efficient runners.
The study, published in the Journal of Strength and Conditioning Research, examined a measure called running economy, which gauges how efficiently the body uses oxygen at a certain pace. Across the three age groupings of the study's 51 participants (18 to 39, 49 to 59, 60 and older), running economy was about the same.
