Have you ever wondered why we have to walk so far to get our luggage at the airport? The long walk is actually designed to protect our lower back!
When we are sitting without a proper back support or sitting for a prolonged period, we tend to flex a little bit. Flexing forward will lengthen the back muscles, and this phenomenon is called muscle creeping. During muscle creeping, there is a constant load applied to our muscle, which can damage the microfibers in the muscle and causes inflammation. Hence, the muscles become tight, and the range of motion is decreased. Therefore, you are more prone to injure your back when lifting right after prolonged sitting.
Studies have shown that 70% of new range of motion is restored after 5 mins of walking or standing. That is why the walk to the baggage claim is designed to be so long in the airport. It is designed for the safety of your back. Long airport walks are good for your back!
