No-nonsense, no agenda. Just reasoned information and advice about running, based on peer-reviewed research.

Mammals with bigger brains are better “athletes”
by Dave Munger in Science-Based Running
How do you measure a non-human animal’s VO2 max? Put it on a treadmill, just like you would with a human. What do you do with that information? If you’re David Raichlen and Adam Gordon, you use it to figure out if there’s any relationship between an animal’s ability as an “endurance athlete” and its [...]... Read more »

What’s the minimum (and maximum) exercise to improve health?
by Dave Munger in Science-Based Running
The U.S. Department of Health and Human Services currently recommends that adults engage in exercise at least 150 minutes per week. They also say that more exercise is even better, but that also suggests that doing somewhat less than 150 minutes per week might be better than nothing. If you’re an active runner, you might [...]...

Do world-class sprinters really move their legs no faster than ordinary runners?
by Dave Munger in Science-Based Running
The speeds attained by world-class sprinters like Usain Bolt are simply unfathomable to me. During today’s workout, I ran at nearly top speed for a set of 400-meter repetitions: About 6-minute-mile pace, or 10 miles per hour. Sure, I could probably hit 15 mph over 50 meters or so, but that would be about it. [...]... Read more »

Nutrition during a run: Yep, consuming carbs improves performance
by Dave Munger in Science-Based Running
This summer I’m reading Tim Noakes’ massive volume Lore of Running, bit by bit, then reporting the critical bits back to you. Last week I covered fatigue and exhaustion, discussing why we get tired when we do. This week I’m finishing up Noakes’ chapter on energy systems and running performance. I started running in the [...]... Read more »

Cadence and injuries: Once more, with science
by Dave Munger in Science-Based Running
The plan for this site has always been to supplement discussion of peer-reviewed science with other reasoned discussions based on anecdotes and experience. When I’m discussing the peer-reviewed research, I always include the Research Blogging icon you see at the top of this post. When I’m discussing books or other non-peer-reviewed sources, I don’t. That [...]... Read more »

Barefoot running is (sometimes) more efficient
by Dave Munger in Science-Based Running
Runners around the world are currently engaged in an epic battle about the future of their sport: Whether running barefoot is better than running wearing shoes. I wrote an article about it last year, and despite the fact that Seed’s website doesn’t accept comments, I heard from a lot of runners on both sides of [...]... Read more »

Carbo-loading: An idea whose time has passed?
by Dave Munger in Science-Based Running
In 1967, a landmark study led by Bjorn Ahlborg found that military recruits could improve their ability to perform endurance tasks after a carbohydrate depletion and loading regimen over the preceding week. The dietary restrictions were quite extreme, and were coupled with exhausting exercise: A hard workout followed by three days of a low-carb diet, [...]... Read more »

More on marathoning and heart disease
by Dave Munger in Science-Based Running
Sure, marathons are enjoying a tremendous rise in popularity, as the above video from the 2010 New York Marathon illustrates vividly, but is it possible that running too many marathons can be harmful to your health? This is the second of a pair of posts on the issue. On Friday, I discussed a 2009 report [...]... Read more »

A complex picture on marathoning and heart disease
by Dave Munger in Science-Based Running
Jim Fixx was an overnight sensation as a recreational runner who had worked himself into shape and written a book about the health benefits of running. But when he died of a heart attack shortly after a run at age 43, he became the poster-child for the idea that running can actually be hazardous to [...]... Read more »
