**Neuromuscular Changes Due to Sitting** Another question that I commonly get about the back is “why do the lower back muscles become so overworked”
Like so many questions, this one doesn’t have just a singular reason, rather it is usually multifactorial. The important part is realizing which factors may apply to you. Our back may become overworked due to: biomechanical issues, congenital issues, muscle firing patterns, neuromuscular activity, etc.
When it comes to neuromuscular activity, it’s important to first realize that the muscles of the spine simply are almost always “on”. They provide stability and safety to our spine so it makes sense that the are active. The problem is that our core stabilizers are often much less active. Core example *wink*, how many people can actually say they properly engage their core while sitting? What about while standing and leaning over the sink washing your hands or doing dishes? During these activities, your spine is placed on load (see the prior post), which means your back muscles are active and helping to support the spine. What this leads to is improved communication between the brain and the back and decreased communication to the core (unless you’re awesome and keeping the core engaged). This makes the lower back muscles more of the “go to” muscle whenever we need to do any lifting, carrying, or most importantly, rock climbing. Which as you can imagine… means those muscles become overworked.
The take-away? Keep your core engaged, and train it for what you do! It takes mindfulness and functional training, but it’s well worth your time to protect your back.
