Gait speed
Also called: walking speed test, 4-meter gait speed
What it means
Gait speed is how fast you walk at your normal pace, usually measured over a short, fixed distance like 4 meters. It's a simple way to check muscle strength, balance, and overall physical function.
A slower walking speed can point to weaker muscles or poor balance, both of which raise your risk of falling and breaking a bone.
Gait speed is simply how fast you walk your normal pace. In clinics, it's often measured as a 4-meter walking test: you walk a short, flat distance at your usual speed while someone times you, and the result is reported in meters per second. It's quick, needs no special equipment, and gives a surprisingly useful snapshot of overall physical function.
This test matters for bone health because it reflects the condition of your muscles, nerves, balance, and joints working together, not just your bones. A slower gait speed can signal reduced muscle strength or power, poor balance, or early sarcopenia, all of which raise the risk of falling. Since falls are the most common trigger for fragility fractures, gait speed adds information that a bone density scan alone cannot capture.
Doctors and researchers often pair gait speed with other functional tests, like grip strength, timed up-and-go, or sit-to-stand tests, because together they paint a fuller picture of fracture risk than density measurements alone. These functional measures can also be repeated more often than a bone density scan, which is typically spaced out over a year or more. If your gait speed seems slower than it used to be, it's worth mentioning to your doctor so they can look at strength, balance, and fall risk as part of your overall bone health picture.
How fast you normally walk is a simple signal of muscle strength, balance, and fall risk.
