Human locomotion needs ecology
Our bodies don’t exist outside of nature
In her book Movement Matters, biomechanist Katy Bowman makes a case for the importance of movement in our lives — not fitness confined to an hour on an exercise machine, but real-life movement: walking, foraging, strolling, meandering, running a bit, playing. For hours. The kinds of movement our species evolved to engage in over many eons.
Throughout the book, Bowman addresses the many ways that natural, everyday movement for long periods of time is good for us (mental health, myopia, bone density, cardiovascular strength — the list is endless). She also returns repeatedly to the flaws in the ways we study and understand human movement.
As I wrote about in a previous article, our understanding of human health and locomotion is still too tied to a metaphor of the human body as mechanical. Bowman makes this point for, essentially, all of science, but in particular science related to the human body. Using the example of calculating the amount of “work” involved in a bicep curl, she writes that,
“Biomechanics is the study of mechanical laws relating to the movement or structure of a living organism. But applying mechanical laws to living things is tricky, because the tissues that comprise the body aren’t as easy to model as metals are. . . .
