Filter by: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.
The purpose of this pilot is to assess the feasibility and potential effectiveness of three specific e-health approaches. One approach, SparkPeople.com, involves the use of social media and can be accessed through a free website. This approach has the potential to provide support through an on-line community as well as a number of diet/weight and physical activity related tools. A mobile phone application is also available for those with smart phones. The second approach, BodyMedia, involves the use of an objective monitoring device that tracks all activity. This information can be uploaded to a website to provide ongoing monitoring and feedback about activity and energy expenditure. The third approach, P90X, involves a DVD based resistance focused exercise program. While DVD programs are not necessarily considered e-health, participants will be encouraged to participate in online community forums associated with the program. All participants, regardless of randomization, will be given 4 point of decision prompts that are laminated 8.5x11 posters encouraging healthier behaviors to display in various areas of their home. The specific aims are: 1. To assess the effect of the intervention on weight, activity levels, depression, and adherence. 2. To determine level of interest, perceptions, feasibility and satisfaction of the proposed interventions (i.e. SparkPeople.com vs. BodyMedia vs. P90X) with particular attention to: 1) social media; 2) food logs; 3) objective monitoring of physical activity; 4) use of point systems
Specific aims are: 1. Evaluate the feasibility of the intervention related to (1) girls' participation; (2) adherence to protocols; and (3) user and provider (nurse and PA Club instructors) satisfaction. 2. Explore if participants in the intervention group, compared to those in the control group, show improvement in the primary outcome of minutes of moderate to vigorous physical activity (MVPA; measured by accelerometer), and also secondary outcomes of self-report of MVPA, cardiovascular fitness, body mass index, percent body fat, and waist circumference at 6 months. 3. Explore if the primary outcome is mediated by cognitive (perceived benefits of PA, perceived barriers to PA,PA self-efficacy, social support, norms, models) and affective (enjoyment of PA) variables. 4. Explore if participants in the intervention group, compared to those in the control group, have greater minutes of MVPA at 7 months.
This study is designed to explore a new approach to help people with chronic obstructive pulmonary disease (COPD) become more physically active. Through weekly telephone sessions with a health coach utilizing motivational interviewing, participants will be empowered to set goals for increased physical activity (emphasis on walking). The objective of the study is to determine if telephone-based health coaching is a reasonable and effective way to increase physical activity, as measured by a gold-standard activity monitor, in people with COPD.
The purpose of this study is to determine the feasibility and efficacy of a behavioral intervention, delivered through an existing social networking website (Facebook), on physical activity (moderate-intensity minutes per week) among young adult cancer survivors compared to a self-help education condition. For this research study, investigators will conduct a 12-week randomized trial. After a baseline survey, weekly messages, a pedometer, goal-setting tool, physical activity log and discussion prompts will be delivered to the intervention group. Comparison group participants will receive links to websites with self-help education materials. After 12 weeks, a follow-up survey will be given to both groups. Changes in physical activity, quality of life and psychosocial factors will be examined. The investigators hypothesize that those receiving the intervention will have improved physical activity behaviors at 12-week follow-up relative to those in the comparison group.
Physical inactivity is a major public health problem and a primary contributing factor to the obesity epidemic. While most Americans do not meet the physical activity (PA) guidelines (30 min/day, 5 day/wk), they do report watching several hours of TV each day, and frequently site "lack of time" as a barrier for engaging in PA. The Physical Activity and Leisure-time Study examines an approach convert sedentary TV watching into active TV watching time by having adults step in place during commercials (TV commercial stepping).
In this randomized controlled trial, we will examine the effect of a 3-month exercise training (aerobic exercise versus resistance exercise) without calorie restriction on total and regional adiposity, ectopic fat in the liver and skeletal muscle, and risk of type 2 diabetes in overweight girls.
