Frequently Asked Questions
How do I measure gait speed at home?
Mark a 10-meter straight path with tape. Walk at your normal, comfortable pace. Time only the middle 4 meters (from meter 3 to meter 7) to allow for acceleration and deceleration. Divide 4 by the elapsed seconds to get m/s. For example, if the 4-meter segment takes 4 seconds, your gait speed is 1.0 m/s (normal).
How do I measure grip strength without a dynamometer?
A hand dynamometer is required for an accurate measurement (around $30 to $50 for a basic model). Without one, the grip strength field cannot be accurately completed. Physical therapy clinics, some gyms, and many pharmacies with health screening services have dynamometers available.
Can I improve my functional fitness age significantly?
Yes. Research shows that structured exercise programs targeting the specific deficits identified by these tests - balance training for single-leg stance, resistance training for grip and chair stands, walking or aerobic exercise for gait speed - can improve scores meaningfully within 8 to 16 weeks. Physical therapists specialize in this type of targeted functional rehabilitation.
What is a normal 30-second chair stand count for a 70-year-old?
For a 70 to 74-year-old female, the average range is 10 to 15 reps. For a 70 to 74-year-old male, it is 12 to 17 reps. Scores above the upper end indicate excellent lower body strength; scores below the lower end suggest intervention may be beneficial.
