Unfit or weak people react sooner to sounds of approaching danger than strong, healthy people – which may be an evolutionary adaptation to allow them a larger margin of safety, says a new study.

Test subjects listened to a sophisticated sound system that mimicked an approaching object, explained John Neuhoff, an evolutionary psychologist at the College of Wooster in Ohio, U.S., and co-leader of the study.

The 'virtual object' sounded like a motorcycle passing on a highway, approaching the subject at 15 m/s and then whizzing past them. The subjects were asked to hit a key when they thought the sound was right in front of them.

Fitness was measured by two variables: heart rate after a bout of moderate cardiovascular exercise and muscular power, measured by the strength of their hand grips.
