Background: Most preschool centers provide two 30-min sessions of gross-motor/outdoor playtime per preschool day. Within this time frame, children accumulate most of their activity within the first 10 min. This paper describes the design and baseline participant characteristics of the Short bouTs of Exercise for Preschoolers (STEP) study. The STEP study is a cluster randomized controlled study designed to examine the effects of short bouts of structured physical activity (SBS-PA) implemented within the classroom setting as part of designated gross-motor playtime on during-school physical activity (PA) in preschoolers. Methods/Design: Ten preschool centers serving low-income families were randomized into SBS-PA versus …

On average, starting an exercise training program decreases one’s risk for chronic disease. However, there is remarkable individual variability in physiologic responses to exercise training. The activity and inactivity during the remaining 95% of the day (when the individual is not training) is rarely considered. The overall objective of this dissertation was to apply validated sedentary behavior (SB) and physical activity (PA) measurement techniques during an exercise training study to determine if time spent in SB and PA outside of training influences the physiological response to training. Twenty subjects participated in a pilot study to determine the feasibility of reducing …

This study used latent class analysis to classify adolescent home neighborhoods (n=344) according to built environment characteristics, and tested how adolescent physical activity, sedentary behavior, and screen time differ by neighborhood type/class. Four distinct neighborhood classes emerged: 1) low-density retail/transit, low walkability index (WI), further from recreation; 2) high-density retail/transit, high WI, closer to recreation; 3) moderate-high-density retail/transit, moderate WI, further from recreation; and 4) moderate-low-density retail/transit, low WI, closer to recreation. We found no difference in adolescent activity by neighborhood class. These results highlight the difficulty of disentangling the potential effects of the built environment on adolescent physical activity.
Providing Further Construct Validity For A Newly Developed Functional-Living Measure: The Movement And Activity In Physical Space (Maps) Score, Andrea M. Morand
Providing Further Construct Validity For A Newly Developed Functional-Living Measure: The Movement And Activity In Physical Space (Maps) Score, Andrea M. Morand
Masters Theses 1911 - February 2014
Older adults face many age-related changes affecting functional ability. Function is defined as the interaction between a person and their real-world environment. Currently, no objective measures of function exist assessing the environmental component. A newly-developed measure of functional-living, the Movement and Activity in Physical Space (MAPS) score, combines accelerometer and geospatial data providing quantitative measurement of real-world function. Because MAPS is a new measure of functional-living, the purpose of the current study was to provide further construct validity for MAPS as a functional-living measure in older adults and to determine what combination of 3 days, using weekend and week days, …
