I was browsing through my hard drive a few days ago when I found an article about spine loads during a golf swing. Since I have a delicate lower back, I thought I would read this article again to see if had missed anything when I read it the first time some years ago. Indeed, I had.
While loads on the lumbar (lower) spine are considerable during the swing, especially in the late downswing, they are not damaging. The caveat is that the discs between the vertebra are viscoelastic and time-rate dependent.
This means they deform when stressed (viscoelastic) and need time to get back to their original shape (time rate dependent). The article noted that “accumulated stress due to repeated swings may lead to disc degeneration, and even submaximal exertions may lead to structural deformation of the lumbar spine.”
What they’re telling us not to do is hit one ball after the other like there’s a race going on. Maybe your back doesn’t feel sore after you do that, but you are putting undue stress on it in any event and not letting it recover. It you do hit balls rapid fire and you do feel your back getting a little sore, that’s a big warning sign.
All of us should hit balls slowly. Rest between each shot. Take some time to review in your mind why the ball you just hit did what it did, and what you want to do with your next swing. Or take a few easy partial swings to rehearse a move you’re working on. Then hit another ball.
At the range, when it is possible to take a swing every fifteen seconds, instead of every five minutes, like out on the course, slow down. It can only help to keep your lower back healthy while playing a sport that challenges it.
