Background Heuristic (ie, evidence-based, rounded) cadences of≥ 100 and≥ 130
steps/min have consistently corresponded with absolutely-defined moderate (3 metabolic …

International physical activity guidelines recommend that older adults accumulate 150
min/week of moderate-vigorous physical activity (MVPA). It is unclear whether meeting this …

The activPAL is a valid measure of step counts and posture, but its ability to determine
physical activity intensity is unclear. This study tested the criterion validity of the activPAL …

Introduction: Acute, laboratory-based bouts of prolonged sitting attenuate lower-limb arterial
endothelial-dependent vasodilation. However, the impact of habitual sedentary patterns on …

Lower-limb arteries, such as the popliteal artery, are a common site of atherosclerosis.
These arteries are habitually exposed to large fluctuations in blood flow during physical and …

Objective To investigate the moderating effect of step count and peak cadence on the
relationship of sedentary time and cardiometabolic disease risk in community-dwelling older …

The activPAL is a widely-used measure of sedentary time but few studies have evaluated its
ability to estimate physical activity intensity. This study determined the accuracy of the …

Acute prolonged sitting studies have been frequently implemented to determine the
physiological effect of sedentary time on vascular and metabolic health. The length of these …

Background Existing analytical approaches used to measure free-living stepping cadence
(steps per minute; spm) characterize stepping two-ways: 1) 60 s epochs without considering …

Gait velocity, or walking speed, has been referred to as the sixth vital sign, and research
suggests that it is highly sensitive to change. Previous research has demonstrated the utility …
