Sit-and-Reach: Females, Age 17
The sit-and-reach test measures hamstring and lower back flexibility. The subject sits on the floor with legs extended, feet flat against the test box, and reaches forward as far as possible. The farthest point reached (in cm) is recorded. Adult norms (ages 20-69) are from the Canadian Health Measures Survey (n=5,188). Youth norms (ages 9-17) are from the Tomkinson 2018 Eurofit meta-analysis (n=464,807 across 27 European countries). Because these come from different studies and populations, the trend chart shows both as a single continuous line, note that the gap between ages 17 and 20 represents a source boundary, not a true biological break.

What these numbers mean for females aged 17
A score around 27.4 cm is typical (50th percentile) for females in this age group. Scores above about 34.3 cm fall near the 75th percentile or higher, indicating above-average performance. Scores below about 20.2 cm fall near the 25th percentile, about 75% of the reference population scored higher.
Percentiles show how common a value is, not whether it is healthy.
