Burstiness And Stochasticity In The Malleability Of Physical Activity, Vincent Berardi, David Pincus, Evan Walker, Marc A. Adams

Psychology Faculty Articles and Research

This study examined whether patterns of self-organization in physical activity (PA) predicted long-term success in a yearlong PA intervention. Increased moderate to vigorous PA (MVPA) was targeted in insufficiently active adults (N = 512) via goal setting and financial reinforcement. The degree to which inverse power law distributions, which are reflective of self-organization, summarized (a) daily MVPA and (b) time elapsed between meeting daily goals (goal attainment interresponse times) was calculated. Goal attainment interresponse times were also used to calculate burstiness, the degree to which meeting daily goals clustered in time. Inverse power laws accurately summarized interresponse times, but …

Stair Versus Elevator Use In A University Residence Hall Setting, Vincent Berardi, Benjamin D. Rosenberg, Sophie Srivastava, Noah Estrada-Rand, Julia Frederick

Psychology Faculty Articles and Research

Objective

Determine the temporal and spatial characteristics of stairs versus elevator use in a university residence hall to inform future physical activity promotion efforts.

Participants

All residents and visitors for a single, four-story residence hall dormitory building located on a college campus in Orange, CA.

Methods

Smart mat systems capable of detecting pedestrian traffic were placed in front of the stairs and elevators on each floor plus a basement. Generalized additive mixed models (GAMMs) were used to compare stair versus elevator usage at different times of the day and on different floors.

Results

Stair versus elevator use varied much more …
