Average full-minute Actigraph counts · min−1, walking speed (km · h−1), and VO2 (ml · kg−1 · min−1) were computed for all walks, at all speeds in all participants.
Outcomes will be the total distance walked and walking speed.
This included unintentional weight loss (assessed as ≥5% decrease in self-reported weight that was reported to be unintentional); exhaustion (if response to the question 'Do you feel full of energy?' was 'no'); weakness (assessed as lowest fifth of grip strength distribution); and slow walking speed (lowest fifth of walking speed).
The following information is collected: total distance and time walked, time/distance to onset of symptoms, the nature and location of symptoms (pain, numbness/tingling, weakness or fatigue), average walking speed, and the reason for test termination should they not walk for the full 30 minutes (symptoms of LSS, fatigue, shortness of breath, dizziness, pain or discomfort due to co-morbidities).
Modifications to the SPPB used in NHANES III did not include the side-by-side and semi-tandem balance tests (assessing only full-tandem balance), and measured gait speed at a pace twice that of the usual walking speed (vs usual speed), referred to herein as fast walk speed.
After completing the full checklist in all four domains, a physical examination takes place that includes height, weight, blood pressure, pulse, handgrip strength and walking speed.
"Weight, height, walking speed, interests.
At walking speed, air is ephemeral stuff.
Average car speed / Average walking speed.
Even our walking speed has increased.
