Bowling Injury Prevention for Older Bowlers: Knee Bend, Slide Control, and Pre-League Stretching

Bowling looks like a low-impact sport, but the repetitive motion of throwing a 10 to 14-pound ball can wear on an older body. The most common bowling injuries in seniors are low back strain, knee pain, shoulder impingement, and elbow tendonitis. Most of these injuries are preventable with three habits: a proper knee bend during the release, a controlled slide on the final step, and a five-minute warm-up before the first frame. A senior bowler who builds these three habits can bowl a 90-game league season without missing a week to injury, well into the 70s and 80s.

The knee bend is the most important. A senior bowler who throws the ball with a stiff back leg puts the full force of the release into the lower back. The correct technique is to bend the front knee 45 to 60 degrees as the ball is released, with the back leg trailing behind for balance. The bend lowers the body, allowing the arm to swing through at a level closer to the lane, and transfers force from the back into the larger leg muscles. A senior with a knee replacement or with severe knee arthritis should still bend the knee, with the depth scaled to comfort. Even a 20 to 30 degree bend is far better than a straight leg.

Slide control is the second key habit. The final step in a bowling approach is a slide, where the foot slides forward on a smooth surface. A controlled slide ends with the foot stopped on the foul line, the body balanced, and the arm following through. A loss of slide control, where the foot either sticks to the floor or slides too far past the foul line, is the cause of most ankle, knee, and back injuries in older bowlers. Slide control depends on shoe maintenance, lane cleanliness, and the bowler's technique. Bowling shoes should have a clean slide sole on the bowler's slide foot (left foot for a right-handed bowler) and a rubber heel for braking. Shoes should be brushed or wiped after each frame to remove debris.

The third key habit is a pre-bowl warm-up. A senior who walks straight from the parking lot to the lane and throws three balls cold is at the highest risk of injury. A five-minute warm-up cuts that risk dramatically. The warm-up should include neck rolls, shoulder circles, gentle torso twists, hip swings, and slow practice swings with a light ball or no ball. The full body should be warm before the first competitive frame. Many senior leagues now include a warm-up routine led by a volunteer before the first ball is thrown.
