Can Fitness Screening be Unbiased?

The UI research team reviewed 140 past studies of differences in various physical abilities between men and women. Their review showed that men were, indeed, physically stronger than women, but found distinct nuances in other differences.

In fact, for tests measuring flexibility and balance, the difference was essentially zero.

The study suggests that in addition to strength and endurance tests, employers should give tests that measure flexibility, balance, coordination, and other forms of movement quality. It suggests that those tests are strong predictors of performance in physically demanding jobs with results that show little difference between genders.

More than 28% of Americans today work in physically taxing jobs such as law enforcement, firefighting, construction, maintenance, or the military, so fitness screening is an increasingly important part of the hiring process.
