^aChair stands were evaluated by asking the participants to stand up and sit down as quickly as possible. Greater measures indicate longer times to complete the task (worse performance)
^bGait was measured with a four meter walk at the participants’ usual speed. Greater measures indicate faster gait speed (better performance)
^cBalance was measured by asking the participant to stand unaided on one leg, with eyes open and closed. High values indicate better ability to sustain a position (better performance)
