Golfer’s Back: Why Your Swing Could Be the Problem

Late summer is peak season on Ottawa’s courses — tee times at Loch March, Eagle Creek, and The Marshes are booked solid, weeknight leagues are in full swing, and everyone’s trying to squeeze in a few more rounds before the weather turns. It’s also the point in the season when our clinic starts hearing the same complaint, over and over: a tight, achy low back that shows up somewhere around the back nine, or the next morning, and doesn’t seem to want to leave.

The instinct is to blame the game itself — or just chalk it up to getting older. But in the clinic, that’s rarely the real story. The golf swing is one of the fastest rotational movements in sport, and when the body can’t rotate well somewhere else, the low back ends up doing work it was never built to do, swing after swing, round after round.

Here’s what’s actually happening in a golf swing, why it tends to catch up with people exactly this time of year, and what helps — beyond just “swinging easier.”

What Makes the Golf Swing So Hard on Your Back

A full golf swing asks your spine to do something almost nothing else in daily life does: rotate at speed, under load, through an enormous range, hundreds of times in the same direction. On the backswing and downswing, your hips and shoulders are meant to turn against each other, and that stored twist releases through the ball at impact. At the top of the follow-through, the spine is combining rotation with compression and side-bend all at once, which is exactly the combination that irritates the small joints and discs of the low back.

Do that eighty or ninety times in a round, always turning the same way, and even a healthy back can start to feel it. That kind of repetition — the same twisting motion, in the same direction, round after round — is exactly the kind of pattern that becomes a breeding ground for imbalances if nothing else in the body is sharing the load. A back that’s already a little stiff or a little weak in the wrong places feels it a lot sooner.

Why It’s Usually Not Really a “Back” Problem

This is the part that surprises most golfers: the low back is often just the part that hurts, not the part that’s actually at fault. It’s the last stop for rotation that should have happened somewhere else first — most often the hips, the thoracic spine (mid-back), or the core and glutes that are supposed to control and decelerate the swing. Even areas further down the chain, like how your feet and ankles move during the swing, can play a role. When any of those areas isn’t doing its share of the work, the low back picks up the slack, swing after swing.

Exactly which area is behind it — and whether the real issue is how well it moves or how well it’s working — is different for every golfer. It’s not something you can reliably sort out on your own, and guessing wrong means treating the part that hurts instead of the part that’s actually causing it.

The Weekend Warrior Effect

Most golfers aren’t playing four times a week — they’re fitting in one round, maybe two, around work and everything else. That means eighteen holes of full-effort, same-direction swings on a body that hasn’t done anything like it since the last round. Add a skipped warm-up, a bag carried or pulled with a rounded, one-sided posture, and a few extra range balls hit at full speed before the round even starts, and the low back is set up to be the first thing to complain.

How Physiotherapy Helps

Treating golfer’s back well means treating the actual cause, not just the sore spot. Depending on what we find on assessment, that typically includes:

Three Things You Can Start This Week

You don’t need an assessment to start protecting your back. These are safe, practical steps you can take on your own:

When to See a Physiotherapist

It’s worth booking an assessment if:

• Low back pain shows up reliably during or after golf
• You’ve noticed your swing shortening or changing to avoid discomfort
• Stiffness from one round is still lingering when you tee off for the next
• You’ve had a specific twinge or “catch” during a swing
• Back pain is starting to limit rounds you’d otherwise be playing
