Junk Science- 15 Minutes on a Stationary Bike Could Make You a Faster Runner

My rebuttal to a Runner’s World Junk Science Article

http://www.runnersworld.com/training/15-minutes-on-a-stationary-bike-could-make-you-a-faster-runner

Articles like this drive me crazy. Based on this article, to improve your 3,000 M time (and probably your 5k time as well) you should hop on a bike and do short intense reps with short rest intervals- right?

Not so fast!  While there are interesting implications for runners in the story and it demonstrates that short intervals with short rest improve speed performance it does NOT by any stretch demonstrate that cycling is the best way to become a better runner!

Observations:

  1. If you take a bunch of runners and one sub set does everything the same, and the other adds additional exercise, the ones doing extra work get faster. Duh.
  2. Among the ones doing extra work, the shorter rest intervals athletes improve the most. Duh.

What if your compared a group of people who did short bursts of running with short rest intervals to runners who trained with short bursts of cycling and short rest intervals? We don’t know for sure but I suspect the answer is that the principal of specificity comes into play and the runners get better at running while the athletes doing the cycling training improve some but not as much as they would if they did the running sprints.

I still don’t understand the running community’s fascination with cross-training. I love to run. Running is the best training for running. Not swimming, not cycling, not yoga, not cross fit, not burpees, not Zumba, or anything else. If you want to get better at running, RUN! Or try Cat Flexing. I’m pretty sure there’s a scientific study showing how it can help you run a faster 5k.

Cat Flexing! The new Cross-Training Fad! Cat-Fit!
