Objectives:

Few social ecological studies have considered the joint effects of intrapersonal and environmental influences on physical activity. This study investigated the interaction of self-efficacy and perceived neighborhood walkability in predicting neighborhood-based physical activity and how this relationship varied by gender and body mass index.

Methods:

Data were derived from a cross-sectional investigation of environmental and psychosocial correlates of physical activity among adults (n = 585). Participants completed a detailed 7-day physical activity log booklet, along with a questionnaire that included measures of neighborhood walkability, self-efficacy, and several sociodemographic items. Factorial analysis of variance tests were used to examine the main effects of and interaction between walkability and self-efficacy.

Results:

In predicting neighborhood-based physical activity, significant interactions were observed between self-efficacy and neighborhood walkability for females (but not for males) and for overweight/obese participants (but not for healthy weight individuals). Women and overweight/obese individuals with low self-efficacy demonstrated substantially greater physical activity when living in a high walkable neighborhood.

Conclusions:

Physical activity research and promotion efforts should take into account both environmental and personal factors and the interrelationships between them that influence active living.

The current study examined whether the distribution of published research papers in the field of sport psychology followed the Lotka-Price Law of scientific productivity. All authors who had published articles in five sport psychology journals from 1970 to 2000 were considered. The impact of those authors was determined by the total number of published papers in all journals. Results provided limited support for the Lotka-Price Law; however, it appeared that the field of sport psychology was less elitist than other fields. Although these findings suggest that productivity in this field is similar to that in other fields of science, more research is needed to shed light on the role of the eminent scientist and the average researcher in the advancement of knowledge in sport psychology.

Given the potential for dance to serve as a way to engage in physical activity, this review was undertaken to examine the use and effectiveness of physical activity interventions using dance among children and adolescents.Five databases were examined for dance-related physical activity interventions published between 2009–2016 fitting the inclusion criteria. Studies meeting the inclusion criteria were then evaluated for studyquality against the Effective Public Health Practice Project assessment tool (Thomas, Ciliska, Dobbins, & Micucci. 2004) and key study information was extracted. Thirteen papers detailing 11 interventions wereobtained. Intervention study quality was rated as weak (based on scoring) for all studies. Multiple forms of dance were used, including exergaming approaches. Four interventions yielded increases in physical activity(reported in six articles), four interventions were inconclusive, and three interventions produced nonstatistically significant findings. Further research is required in this area to determine the effects of dance interventionson physical activity among youth.
