Sit-Ups (1-Min, Cooper): Females, Age 40-49

Sit-ups (1-minute) measure abdominal muscular endurance. Data are from Physical Fitness Assessments and Norms for Adults and Law Enforcement (Cooper Institute, Dallas TX), widely used by US police departments, the FBI, and military branches. The participant performs as many bent-knee sit-ups as possible in 60 seconds. Because the source population is law enforcement candidates, likely fitter than the general public. These norms may be higher 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.
