300m Run (Cooper): Males, Age 40-49
The 300-metre run measures anaerobic power and speed endurance by timing a maximal-effort sprint over a short distance. Data are from Physical Fitness Assessments and Norms for Adults and Law Enforcement (Cooper Institute, Dallas TX, 2013), a reference library of about ten fitness test norm charts. The 300m run norm chart in that monograph is labelled as drawn from Law Enforcement Studies data. Because the source population is law enforcement candidates (likely fitter than the general public), these norms may be faster than population-wide averages. Note: this source is an institutional monograph with no DOI and undisclosed sample sizes; it is the only publication providing full percentile tables by age and sex for this test. Female norms are only available up to age 49; the 50+ brackets were not included in the published tables.

Percentile Distribution (sec)
| Percentile | Value (sec) | Rating |
|---|---|---|
| 5th | 104 | Excellent |
| 25th | 81 | Above average |
| 50th | 67.6 | Average |
| 75th | 60 | Below average |
| 95th | 52 | Poor |
What these numbers mean for males aged 40-49
A score around 67.6 sec is typical (50th percentile) for males in this age group. Times below about 60 sec fall near the 75th percentile or higher, indicating above-average performance (faster is better). Times above about 81 sec fall near the 25th percentile; about 75% of the reference population performed faster.
Percentiles show how common a value is, not whether it is healthy.

This test is one of about ten norm charts in the Cooper Institute's 2013 monograph. Law enforcement academies pick five to six of these tests to build their own field batteries.
