Here’s an interesting one. Research has just come out suggesting that walking at fast speeds or running at slower speeds results in intervertebral discs that are thicker and juicier. Don’t be tricked because despite the title, the evidence only exists for speeds below 2.5m/s and is only relevant to a particular group of ‘trained’ individuals. Nevertheless quite interesting findings and perhaps contrary to popular belief. More evidence for tissue adaptation and the need to load our body in a controlled fashion.
