Even though time is an abstract concept developed and maintained by humans, it seems to direct and determine the health and function of many systems in our bodies. Recent research states that the time of day that you eat has an impact on your cells and their ability to detox. Similarly, the timing of the bones meeting one another during gait has a profound impact on when muscles fire and how the body moves while walking. For example, one of the most important movements of the femur during gait is the “screw down” movement that the happens as the femur meets the tibial plateau and the fibula. The movement of the fibula before the femur screws down is essential for adequate firing of the quadriceps in gait as well as the inhibition (relaxation) of oppositional muscles in the kinetic chain. Maybe timing IS everything?
