Are Chalking Up and Shaking Out Actually Helpful or Persistent Myths?

In this episode, Kris and Paul discuss the dangers of reading only the abstracts of research papers, by taking a look at what science says about chalking up and shaking out. They’ll reference multiple papers including:

Use of ‘chalk’ in rock climbing: sine qua non or myth?

Authored by François-Xavier Li, S. Margetts and I. Fowler; published in the Journal of Sports Sciences in July, 2001.

&

Active Recovery Strategies and Handgrip Performance in Trained Vs. Untrained Climbers

Authored by Jackson G. Green and Stephen R. Stannard; published in the Journal of Strength and Conditioning Research in February, 2010.

They’ll discuss how a study’s design can alter its results and their usefulness, and how key design aspects aren’t always included in abstracts. They’ll compare studies with better/worse designs, reminding us to dig a little deeper into a research paper before accepting the validity of its findings.
