Although the benefits of increased physical activity and exercise are universally recognized, many older persons remain sedentary, and relatively few achieve recommended levels of activity. Effective interventions to reverse the lack of physical activity in older adults are clearly needed. By understanding correlates of inactivity and appreciating those factors that ...

This study examines the formation of group cohesion and social support in exercise classes among former sedentary adults, participating in a Danish community-based intervention.

Past 2-week recall of the number of times and total minutes spent walking for recreation or sport, and ...

This study describes preoperative physical activity in 314 stress-continent women with prolapse planning sacrocolpopexy. Seventy-six percent reported that they engaged in mild, 60% in moderate, and 26% in strenuous exercise (counts are not mutually exclusive). Activity frequencies did not generally differ by prolapse stage. Prolapse substantially interfered with exercise or ...

Assessment of physical activity needs to improve in order to gain a more comprehensive understanding of the relationship between characteristics of the environment and physical activity. Our study evaluated a method [Block Walk Method (BWM)] for observing physical activity along residential sidewalks and streets. The BWM was utilized in 12 ...

Codman's pendulum exercises are commonly prescribed after shoulder surgery and injury to provide grade I and II distraction and oscillation resulting in decreased pain, increased flow of nutrients into the joint space, and early joint mobilization. Many shoulder protocols suggest that weight may be added to these pendulum exercises as ...

METHODS: Using population-based survey data from the 2004 Behavioral Risk Factor ...

It has been proposed that moderate exercise may enhance the immune system. We evaluated whether physical activity at work or at leisure is associated with the risk of pneumonia, and whether the antioxidants vitamin E and beta-carotene affect pneumonia risk in physically active people. A cohort of 16 804 male ...

Exercise has been reported to simultaneously trigger and protect against sudden death, the so-called "The Paradox of Exercise". Differences in fibrinolytic function appear to exist between chronic and acute exercise. The aim of the present study was to assess the fibrinolytic system after strenuous exercise in healthy people and explored ...

BACKGROUND: Chronic inflammation has been implicated in the development of cardiovascular disease, diabetes mellitus, cachexia, and osteoporosis. Regular physical activity has been purported to possess "anti-inflammatory" properties which may limit chronic inflammation. Recently, we hypothesized that toll-like receptor 4 (TLR4) may play a role in activity-induced modulation of inflammation. Therefore, ...

Discrete wavelet transform was incorporated to retrieve time-varying characteristics of heart rate variability under different physical activities. Nine healthy subjects ...

Non-primate mammalian activity cycles are highly variable across and within taxonomic groups. In contrast, the order Primates has historically been recognized as displaying a diurnal-nocturnal dichotomy that mapped, for the most part, onto the taxonomic division between haplorhines and strepsirhines. However, it has become clear over the past two decades ...

Data gathered from a study of reserve component (RC) soldiers who were activated during the spring of 2002, following the terrorist attacks of September 11, 2001, suggested that they were concerned about how the effects of their activation affected their civilian employment. Therefore, the purpose of this study was to ...

Despite the many clear benefits of an active lifestyle, lack of physical activity is a significant health problem in the college population. A key issue in physical activity research is developing an understanding of motivation. Although physical activity takes many forms, most research designed to enhance motivation for and adherence ...

Accelerometers record total physical activity and time spent at different intensities. Pedometers indicate total activity only.

This review has a purpose to summarize the literature on ...

We examined the structure of the expanded version of the Exercise and Self-Esteem Model in a sample of older adults (N = 174; age, M = 66.7 years) across a 4-year period. A panel analysis revealed support for the indirect effects of physical activity (PA) and self-efficacy (SE) on physical ...

Endurance exercise training improves fibrinolysis, but this training-induced adaptation may differ somewhat between men and women. We sought to determine whether the potential gender differences in training-induced changes in selected fibrinolysis measures were related to changes in adiposity and/or plasma lipoprotein lipid levels. Seventeen men and 28 women, 50-75 years ...

Physical exercise leads to minor activation of blood coagulation, which appears to be balanced by a concomitant activation of the fibrinolytic system. The mechanisms underlying this physiological phenomenon are still unknown. To evaluate the role of oxidative stress for exercise-induced activation of coagulation, we investigated if supplementation with alpha -lipoic ...

A meta-analysis examined data from 36 studies linking physical activity to well-being in older adults without clinical disorders. The weighted mean-change effect size for treatment groups (d(C). = 0.24) was almost 3 times the mean for control groups (d(C). = 0.09). Aerobic training was most beneficial (d(C). = 0.29), and ...

In this study, the pattern and correlates of physical activity-related well-being in older adults (N = 174; men = 49, women = 125; mean age = 66 years) were examined across a 6-month exercise trial. Baseline levels of self-efficacy fitness, importance of physical activity, and social support and exercise participation ...

To date, no objective measurements of New Zealanders' physical activity have been reported. The relative contribution of work time activity to total daily physical activity by gender and occupational category has also not been measured objectively in any population. The present study reports such data using pedometer steps counts to ...
