Influence of Anthropometrics on Step-Rate Thresholds for Moderate and Vigorous Physical Activity in Older Adults: Scientific Modeling Study.

Background: Adults and older adults are recommended to engage in 150 minutes of moderate (MPA) to vigorous (VPA) aerobic physical activity (MVPA) per week, with the heuristic message of 3000 steps in 30 minutes (100 steps per minute [spm]). However, this message is based on adult populations, with a paucity of research on step-rate thresholds that correspond to absolute MVPA (moderate=3 metabolic equivalents [METs], vigorous=6 METs) and relative MVPA (moderate=40% estimated MET, vigorous=60% estimated MET) in older persons, who have lower stride lengths and a lower exercise capacity. Also, there is a need to consider the influence of anthropometric differences when quantifying the relationship between step rate and intensity-related physical activity.

Step Rate Thresholds Associated with Moderate and Vigorous Physical Activity in Adults.

Adults are recommended to engage in 150 min of moderate (MPA) to vigorous (VPA) aerobic physical activity per week, with the public health message of obtaining 3000 steps in 30 min. There is a paucity of research on step rate thresholds that correspond to absolute MVPA (moderate = 3 METs, vigorous = 6 METs) with no research evaluating adult relative MVPA (moderate = 40% VO vigorous = 60% VO). Anthropometric differences also influence intensity-related step rate thresholds.

Titchener's law of prior entry states that attended stimuli are perceived before unattended stimuli. Prior entry effects measured with visual stimuli have been generated with both endogenous and exogenous attentional deployment (e.g.

Further evidence in favor of prior entry from endogenous attention to a location in space.

Titchener's (1908) law of prior entry states that "the object of attention comes to consciousness more quickly than the objects which we are not attending to," or otherwise, that attended stimuli are perceived earlier than unattended stimuli.
