BACKGROUND Use of mobile health (mHealth) technology is on an exponential rise. mHealth apps have the capability to reach a large number of individuals, but until now have lacked the integration of evidence-based theoretical constructs to increase exercise behavior in users. OBJECTIVE The purpose of this study was to assess the effectiveness of a theory-based, self-monitoring app on exercise ...

Background Pulling from Self-Determination Theory (SDT; Deci & Ryan, 1985), this study examined whether individuals classified as 'nondependent-symptomatic' and 'nondependent-asymptomatic' for exercise dependence differed in terms of reported levels of exercise-related psychological need satisfaction, self-determined versus controlling motivation and exercise behavior. In addition, we examined ...

Objectives: Motivational and self-presentational processes pervade all aspects of our lives including exercise behaviors. Furthermore, trait perfectionism has been shown to heighten self-presentational tendencies and energize achievement striving (Flett & Hewitt, 2002; Hewitt et al., 2003). How maladaptive and adaptive perfectionism traits relate to these cognitive and behavioral processes spec...

background: diabetes is a common disease that can lead to metabolic abnormalities and chronic complications. today, the positive role of physical activity and exercise, especially walking in health human society and has been approved in prevention and control many complications including diabetes. today, the positive role of physical activities and exercise , especially hi wal king in the healt...

OBJECTIVES Individual differences in adolescent exercise behavior are strongly influenced by genetic factors. The affective response to exercise is a potential source of these genetic influences. To test its role in the motivation to exercise, we estimated the heritability of the affective responses during and after exercise and the overlap with the genetic factors influencing regular voluntary...

A recent study suggests that habits play a mediating role in the association between trait self-control and eating behavior, supporting a notion of effortless processes in trait self-control (Adriaanse et al., 2014). We conceptually replicated this research in the area of exercise behavior, hypothesizing that these associations would generalize to other self-control related behaviors. Sufficien...

PURPOSE Most candidate gene studies on the neurobiology of voluntary exercise behavior have focused on the dopaminergic signaling pathway and its role in the mesolimbic reward system. We hypothesized that dopaminergic candidate genes may influence exercise behavior through additional effects on executive functioning and that these effects are only detected when the types of exercise activity ar...

The authors examined married partners' similarity in reported exercise behavior as a moderator of the association between social support for exercise provided and received by extending an actor-partner dyadic effects model. Participants were married cardiac rehabilitation patients and their spouses (N=99 couples). For couples similar in their reported exercise behavior, a significant associatio...

Regular exercise is associated with better mental health. This association is widely assumed to reflect causal effects of exercise. In this paper we propose that two additional mechanisms contribute to the association between exercise and mental health in the population-at-large: genetic pleiotropy and geneby-exercise interaction. Both mechanisms assume heritability of exercise behavior and a p...

Introduction Why do some people like to run in their leisure time, while other people prefer to watch a video? Are these individual differences in exercise behavior determined by differences in their environment (for example spouse’s exercise behavior, job, school or upbringing) or by differences in genetic predisposition? These are the main questions of this thesis. Furthermore, it is investig...
