Intermediary Effects for Adults’ Physical Activity: Comparison of two Structural Models
Journal Title: Biology of Exercise - Year 2017, Vol 13, Issue 2
Abstract
studies have indicated that past physical activity (pa) participation, exercise self-efficacy (ese), friend support for pa and environmental factors enhance pa. No study has investigated the aforementioned factors within the context of the same theoretical model so far. The current study examined the relationship between past and current pa through both a social cognitive and an ecological model considering the intermediary effects of ese, friend support for pa and neighbourhood environment. The sample consisted of 684 physically active men and women, aged 18-65 years old (M ± SD = 39.16 ± 13.52 years). past and current pa, ese, friend support for pa and neighbourhood environment were assessed. The examined models were analyzed using structural equation modeling. The models proved to be of appropriate fit. In both models past pa had a high positive effect on current pa. Within the social cognitive model past pa positively affected current pa through the effects of ese and friend support. regarding the ecological model, past pa positively influenced pa through the effects of neighbourhood environment, ese and friend support for pa. Future studies should be carried out applying longitudinal data for a better understanding of these associations over time.
