STUDY OBJECTIVES Nitric oxide (NO), a potent vasodilator, is present in the exhaled air of humans. We wished to quantify NO production in patients with abnormalities of the pulmonary circulation. PARTICIPANTS Nine patients with primary pulmonary hypertension (PPH), six with pulmonary fibrosis (PF), and 20 normal volunteers were studied. INTERVENTIONS All subjects were studied at rest and du...

According to national surveillance studies, participation in leisure-time physical activity remains low among minority women. Furthermore, the correlates of such activity in this group are not well understood. To better understand the environmental, policy, and sociocultural correlates of physical activity among Latina immigrants, six focus groups were conducted in rural North Carolina. Among t...

PURPOSE To examine 1) relationships between adult PA at 35 yr and PA as a child, and 2) the influence of enhanced primary school physical education (physed+) and of parental PA upon the long-term tracking of PA in the offspring. METHODS PA data from the 1970-1977 Trois-Rivieres Growth and Development Study, completed when the children were aged 10-12 yr, were compared with PA data collected o...

INTRODUCTION Although the benefits of physical activity and exercise are widely acknowledged, many middle-aged and elderly individuals remain sedentary. This cross-sectional study aimed to identify the external and internal barriers to physical activity and exercise participation among middle-aged and elderly individuals, as well as identify any differences in these barriers between the two gro...

AIMS Our aim was to test the hypothesis that angiotensin II receptor blockade combined with exercise training after myocardial infarction (MI) could attenuate post-MI left ventricular remodelling and preserve cardiac function. METHODS AND RESULTS Sprague-Dawley rats underwent ligation of the left descending coronary artery, resulting in MI, or a sham operation. Losartan treatment and exercise...

BACKGROUND The prevalence of exercise-induced bronchoconstriction among British children by ethnicity has not been studied. METHODS Peak expiratory flow rate (PEFR) was measured before and after an exercise challenge test using a cycle ergometer in 593 nine year olds from Scottish and inner city English schools. Logistic regression analysis was carried out to assess the association between ch...

OBJECTIVES To evaluate the efficacy of pomegranate juice supplementation on matrix metalloproteinases2 and 9 serum levels and improving antioxidant function in young healthy males during exhaustive exercise. METHODS The study was conducted at Ardabil University of Medical Sciences, Iran, in 2010-11 and comprised 28 healthy subjects in 18-24 age bracket. They were randomly divided into control...

OBJECTIVE Interventions that address the built environment present an opportunity to affect behaviours such as physical activity. The purpose of this study was to evaluate a community walking map developed for eight neighbourhoods in the City of Edmonton (COE). METHOD A walking map developed in partnership with the COE's Walkable Initiative was distributed to 11,994 households across eight ne...
