BACKGROUND There is limited evidence on the causality of previously observed associations between neighborhood traffic safety and physical activity (PA). This study aims to contribute to this evidence by assessing the extent to which changes over time in neighborhood traffic safety were associated with PA. METHODS Data were accessed from the national survey Netherlands Housing Research for 20...

Three hundred nine male insurance underwriters had near-maximal treadmill exercise tests following clinical evaluation. Thirty of the subjects developed ischemic type ST segment depression during or after exercise not associated with anginal pain. Thirteen of the ischemic responders participated in a supervised physical training program which led to increased exercise capacity. Four of these ha...

BACKGROUND Exercise testing may be of value in identifying a group of children at high risk of subsequently developing respiratory symptoms. As few longitudinal studies have investigated this issue, the bronchial hyperresponsiveness to exercise in asymptomatic children was evaluated as a risk factor for developing asthma related symptoms in young adulthood. METHODS A community based sample of...

This study aimed to determine the factors associated with exercise behavior based on the theory of planned behavior (TPB) among the sarcopenic elderly people in Cheras, Kuala Lumpur. A total of 65 subjects with mean ages of 67.5±5.2 (men) and 66.1±5.1 (women) years participated in this study. Subjects were divided into two groups: 1) exercise group (n=34; 25 men, nine women); and 2) the control...

Tendons can be considered in two functional groups, those contributing to energetics of locomotion and those acting solely to position the limb. The energy-storing tendons in both human and equine athletes have a high frequency of injury with similar pathophysiology. In previous studies, high-intensity exercise appears to induce a disruption of the matrix rather than functional adaptation in ad...

The current study examined the ability of interand intra-individual characteristics to predict the likelihood and duration of exercise as well as mood. One hundred forty-nine undergraduates (mean age = 19.11; 53% women; 79.19% White) participated in a six-day study. Online surveys measured participants’ self-reported exercise duration, emotion-regulation ability, hostility, depressive symptoms,...

To determine if changes in pulmonary capillary wedge pressure could be determined from the pulmonary blood volume (PBV) ratio response on exercise-gated blood pool images, 42 patients had simultaneous exercise-gated blood pool imaging and hemodynamic monitoring during cardiac catheterization. Nine patients were normal and 33 patients had cardiac disease. Changes in the PBV ratio were determined...
