Multiple sclerosis (MS) is associated with a large reduction in physical activity behavior, and emerging evidence indicates that this reduction might be correlated with symptoms and self-efficacy. The present study examined the nature of the associations among MS-related symptoms, exercise self-efficacy, and physical activity behavior in 80 individuals with a ...

BACKGROUND: Self-report measures of physical activity have well-known drawbacks, and physiologic measures alone do not account for behavioral variables important in the perception and performance of physical activity. Therefore, we considered multiple measures to quantify physical activity in community-dwelling men and women with chronic stroke. METHODS: This analysis included data ...

To identify the extent of physical performance differences between active and sedentary subjects taking into account sexual dimorphism physical activity level was recorded by interview from a sample of 319 young university students of both sexes. Anthropometric variables and physical performance values were obtained. The sex factor was the main ...

It has been suggested that the low level of effectiveness of youth interventions is due to a lack of knowledge regarding the mechanisms responsible for behaviour change. The identification of behaviour mediators is necessary for the progression of physical activity research, as it allows researchers to determine which components of ...

PURPOSE: Arterial stiffness, an independent risk factor for cardiovascular disease, increases with advancing age. Arterial stiffness is improved by regular exercise, but individual responses to exercise training are variable. Given that estrogen and estrogen receptor-alpha (ER-alpha) can induce vasodilation and can exert an antiatherosclerotic effect in vessels, we hypothesized that ...

Rheumatoid arthritis (RA) is a chronic inflammatory auto-immune disease, causing progressive damage to the musculoskeletal system. Many patients with RA also suffer from accelerated muscle loss or cachexia, which contributes to the loss of physical function and quality of life. Physical activity plays a central role in the management of ...

Perceptions of one's environment and functional status have been linked to physical activity in older adults. However, little is known about these associations over time, and even less about the possible mediators of this relationship. We examined the roles played by neighborhood satisfaction, functional limitations, self-efficacy, and physical activity in ...

OBJECTIVES: To better understand the co-occurrence of smoking and physical inactivity. METHODS: A review of 5 databases identified 50 articles reporting empirical relationships between smoking and physical activity (PA). RESULTS: Almost 60% of the articles reported a definitely negative association, but this relationship was often attenuated or reversed among adolescents ...

Physical activity is associated with improved fibrinolytic activity and reduced risk for cardiovascular disease. High levels of leptin and low levels of adiponectin, both adipocyte-derived hormones, or adipokines, are related to dysfibrinolysis and risk for cardiovascular disease. In this study, we explored if improved fibrinolytic activity during exercise could be ...

BACKGROUND: Both urban and rural adults are likely to be inactive, but rural adults have less access to exercise classes or facilities to increase physical activity. OBJECTIVES: To evaluate whether a telephone-only motivational interviewing (MI) intervention would increase daily physical activity of rural adults. METHODS: This randomized controlled trial enrolled ...

Epilepsy is a common disease found in 2% of the population, affecting people from all ages. Unfortunately, persons with epilepsy have previously been discouraged from participation in physical activity and sports for fear of inducing seizures or increasing seizure frequency. Despite a shift in medical recommendations toward encouraging rather than ...

Activity engagement has long been linked to improved subjective well-being (SWB) in old age. However, recent studies testing Vallerand et al.'s (2003) Dualistic Model of Passion suggest that the type of passionate activity that underlies activity engagement might influence the extent to which individuals benefit from an active lifestyle. In ...

Reviews have reported mixed findings for associations between physical activity and proximity to a range of environmental resources. Initially most studies used self reported proximity, but more are now using GIS techniques to measure proximity objectively. We know little about the extent of agreement between self reported and directly measured ...

OBJECTIVE: Delayed heart rate recovery (HRR) following exercise testing, an indicator of decreased autonomic nervous system activity, is associated with an increased risk of cardiovascular events. Because autonomic nervous system function may be associated with fibrinolytic factors, we tested the hypothesis that delayed HRR is associated with elevated fibrinolytic factors. ...
