Filter by:Healthy but sedentary aging leads to increased morbidity and mortality of cardiovascular disease. This is partly due to the accumulation of Advanced Glycation Endproducts (AGEs) and the stiffening of the myocardium and arteries. New medication has been developed to break these AGE-crosslinks to improve cardiovascular compliance. The positive influence of regular physical activity is well known for cardiovascular disease and aging. Therefore, what is the most effective intervention, physical exercise and/or new medication AGE-crosslink breakers, in improving the cardiovascular and cerebrovascular compliance and improving the endothelial function in healthy sedentary elderly.
Childhood obesity is a major public health threat. Physical activity and healthy eating contribute to the maintenance of healthy weights. Individually oriented behaviour change programs may not be able to overcome the influence of what has been called an obesogenic environment. Action Schools! BC (AS! BC) used a socio-ecological approach to enhance opportunities for physical activity and healthy eating in elementary schools and created systemic change at the provincial level. AS! BC helps elementary schools customize action plans, based upon their local context, to contribute to the health and well-being of children and the school community. Pilot research showed that AS! BC was an effective and feasible model. The provincial dissemination of AS! BC has been launched and partners from across many sectors are involved to enhance the sharing of knowledge and increase the implementation of the AS! BC model across British Columbia. The dissemination provides an unprecedented opportunity for evaluating how changing the school environment can promoted healthy weights in children. The dissemination was evaluated using a cluster randomized design; 30 elementary schools (n = 1529 consented children) from four (out of five) provincial health authorities volunteered to participate. The primary goals of the research are: 1. to determine if the Action Schools! BC (AS! BC) model is an effective approach to positively change school environments and health related behaviours of children from diverse geographical regions and cultural groups, and 2. to determine if the supports provided to schools or the community context influence the uptake and use of the AS! BC model. This research will contribute to the science of obesity prevention and knowledge use as well as public health practice.
In this study, people who have symptoms of post polio will take oral glutathione supplements for three months. Their levels of fatigue, physical function, sleep disturbance, impairment and emotional distress will be measured with both subjective and objective measures.
Several environmental factors have contributed to the growing pandemic of obesity. It has been described that some characteristics of food and built environment have an influence on patterns of food consumption and physical activity of people in a certain place. We have designed a cross-sectional study to describe some aspects of the food environment (community and consumer) and the frequency, distribution and characteristics of the space available to perform physical activity in three neighborhoods of Buenos Aires city. Three neighborhoods of Buenos Aires (with representativity), from different socioeconomic strata, will be selected by convenience to conduct this study. The study will consist on three stages: first, the generation of the sampling frame of food stores, public and private spaces available for carrying out physical activity, and the development of a tool designed to evaluate the availability of healthy foods in supermarkets and grocery stores. Finally, a sample of those stores will be randomly selected for assessing the availability of selected foods. In Argentina, the knowledge of the food environment is limited. We believe that the information obtained in this study will contribute to a better understanding of the subject.
This randomized trial aims to assess if a well defined subgroup of breast cancer patients benefit from a controlled physical activity program. All patients will be screened for their physical ability to complete the interventional exercise program. Only patients capable and willing to take part in this study and meeting all inclusion and exclusion criteria will be randomized. All patients are to receive identical counseling for ideal nutritional, life-style and physical activity. Patients randomized to Arm 2 will additionally undergo a controlled and observed program of physical activity for a period of 6 months. Thereafter the patients are expected to adhere to a comparable, unobserved exercise program at home.
The purpose of this study is to determine whether an interactive exercise videogame bike is effective in improving physical activity adherence, motivations to do physical activity, and physical fitness among families. Families receive either an interactive videogame bike and gaming console, or a traditional stationary bike which is placed in front of the television, to keep in their home for six months. It is expected that families within the videogame bike condition will show greater exercise adherence. It is also expected that these families will have higher self-reported physical activity levels, greater motivation to do physical activity, and improved cardiovascular fitness at the end of the three month period compared to the families in the stationary bike condition.
The purpose of this Randomized Controlled Tria (RCT) is to evaluate the effects of a transformational teaching intervention in comparison to 'standard educational practices' within school-based physical education classes (within three Canadian provinces; British Columbia, Ontario and Nova Scotia) across 5 months.
The primary aim of this pilot study is to test the efficacy of a worksite intervention for reducing daily sedentary time and improving risk factors for cardiometabolic disease (e.g., measures of adiposity, anthropometrics, cardiorespiratory fitness) among sedentary, overweight, full-time working adults as compared to a waitlist control. A secondary aim will be to test pedal time at work as a measure of compliance with the intervention.
Objective: To assess the relationship between maternal cardiovascular capacity and aerobic water exercise during the gestational periods of hemodynamic overload. Study design: randomized clinical trial, with 41 healthy pregnant women assigned to one of two groups: Control and Water exercise. Maternal cardiovascular capacity (maximum oxygen consumption, cardiac output, stroke volume, heart rate and mean arterial pressure), physical performance (relative HR, treadmill speed and self-perceived exertion) and neonatal outcome (gestational age, weight, Apgar index and length of infant's hospitalization) were assessed. Means were evaluated by dependent and independent t-tests, and proportions by the chi-square method (p<0.05). Results: The control variables showed that the groups were homogeneous. Water exercise was associated with maintenance of VO2max, increase in stroke volume and cardiac output, and better performance on stress tests in the third trimester of gestation. No significant difference in neonatal variables was observed. Conclusion: Water exercise maintained cardiovascular capacity and performance under submaximal stress, and did not affect hemodynamic adaptation to gestation or neonatal outcome.
Recently integrated in clinical practice, the Global Initiative for Chronic Obstructive Lung Disease (GOLD) classification states that a mild (stage I) chronic obstructive pulmonary disease (COPD) is present, in a smoker, when the postbronchodilator forced expired volume in 1 second (FEV1) to forced vital capacity (FVC) ratio is < 0.7. A major change that was introduced by the GOLD classification system was that COPD could be diagnosed despite an FEV1 that is within normal predicted values (above 80% predicted). Because it suggests diagnosing and detecting COPD earlier than done until very recently in medical practice, the GOLD standards bring in a new reality to clinicians. In fact, this novel COPD classification comes with new research challenges because the functional impacts and systemic consequences related to COPD are mostly documented in patients with moderate to severe stages with little information specifically in GOLD stage I COPD. This information is important if the investigators are to convince physicians that GOLD stage I COPD needs to be diagnosed and eventually treated. The investigators aimed to characterize GOLD stage I COPD patients according to activity-related dyspnea. More specifically, our objectives were to compare: i) baseline pulmonary function ii) exercise capacity iii) quadriceps muscle function iv) levels of physical activity in daily life between symptomatic (Sx) GOLD stage I COPD patients, asymptomatic (ASx) GOLD stage I COPD patients and healthy control subjects (CTRL). The investigators reasoned that exercise tolerance and physical activity levels would be decreased in Sx GOLD stage I COPD patients as it would be similar between ASx GOLD stage I COPD patients and CTRL.
