1. An electronic device configured to be worn by a user, the electronic device comprising:
a housing;
a first sensor that measures a motion of the housing;
a second sensor that measures a heart rate of the user; and
control circuitry configured to:
determine walking periods based on the motion of the housing, wherein each of the walking periods has a distance component and a speed component;
determine activity information based on the heart rate of the user and the motion of the housing; and
calculate a 6 minute walk distance for the user as a function of the distance component, the speed component, and the activity information.
