Davis's Law - The body needs stress, however, too much, or too little, and the body breaks down. Part 1
Our bodies are made of connective tissue – blood, bone, and fascia, which adapt to our environment. Connective tissue also adapts to stress, too much or too little stress and the tissues respond negatively. If you’re chronically sedentary, the bones aren’t stressed enough, they decalcify, and osteoporosis sets in. Blood reduces in volume which raises your heart rate, thickens your blood, and increases the work/stress on the heart. When movement doesn’t happen often enough, or with enough variation, the body develops adhesions causing thickening of the tissue. —-
Fascia, or fibrous connective tissue, connect everything in the body to give it structure and support. Connected to muscles and nerves, the fascia runs for long distances in the body, impacting other structures that are far from any given moving joint. Muscles don’t work independently, and you can’t think about muscles as just having an origin and an insertion. —-
Fascia optimizes the spread of force through the body on a functional level. When you create a line of stress in the body along a line of fascia it becomes depolarized and attracts fibroblasts to the area, which begin laying down collagen and creating stability and shape. Moderate and varied stress is adaptive - the longer a line of collagen is, the more pliable, resilient and strong it becomes. However, this process doesn’t happen when there is rigidity or over-repetition of the same stressors. To optimize the health and function of our fascia, we need to apply different stress loads to our bodies, and move at different speeds and at different angles.
