Is this not simply explained by the body becoming more econonmical at repeating the same action over time?
After 6 weeks of daily running the body will adapt to be more effcient at running, so won't need so much energy to perform the same activity.
- rusbus 7y agoThat would make sense in an average person, but if you're an elite who is physically capable of back to back marathons, you don't have that much more running economy to gain -- after thousands of lifetime miles, your running economy is already near optimal.
- Scarblac 7y agoI don't think so. For instance, pro cyclist have been doing nothing but cycling training for years and years. And still, this effect shows up a few weeks into a Grand Tour. As they mention at the end of the article, from gorging research (eating as much as possible to gain weight) it is also known that the body can't ingest more calories than about 2.5x times the normal daily energy output. So it's more likely that that is the limiting factor -- in the first weeks you have some reserves to burn, but when those are gone your body doesn't burn more energy than it can take in.
