A value around 60.0 s is typical (50th percentile) for females in this age group.
Scores above about 60.0 s fall near the 75th percentile or higher, indicating above-average performance. Scores below about 48.4 s fall near the 25th percentile; about 75% of the reference population scored higher.
The test has a 60-second ceiling, so percentile norms are only informative from age 50 onward.

This test has a 60-second maximum. Most healthy adults under 50 can
hold a single-leg stance for the full 60 seconds, so this metric is
most informative for ages 50 and above. Where multiple percentiles
equal 60 s, the test cannot distinguish performance at those levels.
This percentile chart shows how common a value is, not whether it is healthy.
