Filter by:The purpose of this study is to compare the time spent in glucose target range (4.0-10.0 mmol/L) during exercise and in recovery using three different basal insulin management strategies for prolonged aerobic exercise: A) pump suspension for the duration of the activity, starting at the onset of exercise; B) A 50% basal rate reduction, performed 90-minutes in advance of exercise for the duration of the activity; and C) An 80% basal rate reduction, performed 90-minutes in advance of exercise for the duration of the activity.
Mindfulness interventions are increasingly offered to undergraduate students at universities world-wide, however the evidence base is very limited. The objective is to evaluate effects of a customized mindfulness intervention (called Mindfulness-Based College) on undergraduate student health. A superiority randomized controlled trial with parallel groups will be performed with 30 participants in each arm. Participants will be randomly assigned to Mindfulness-Based College or health education waitlist control. Investigators will be blinded to treatment allocation. Participants will be assessed at baseline, 10 weeks, and six months. The primary outcome is a college health summary score, including seven evidence-based determinants of health particularly relevant to college student well-being: body mass index, physical activity, diet, alcohol consumption, sleep quantity, perceived stress, and loneliness. Primary intention-to-treat analyses will evaluate whether MB-College vs. control is associated with the summary score, utilizing generalized linear models. Secondary analyses will evaluate which, if any, of the seven determinants of health are driving associations.
The effect of small-sided team sport training and protein intake on muscle mass, physical function, and adaptations important for health in untrained older adults was examined. Forty-eight untrained older (72±6 years) men and women were divided into either a team sport group ingesting a drink high in protein (18 g) immediately and 3 h after each training session (TS-HP, n=13), a team sport group ingesting an isocaloric drink with low protein content (3 g; TS-LP, n=18), and a control group continuing their normal activities (CON, n=17).
Heart failure affects not only the cardiovascular system with structural abnormalities of the heart, but also the musculoskeletal system, leading to exercise intolerance. Objective: To evaluate the effects of a short-term exercise protocol and phototherapy, on the functional capacity and inflammatory markers in patients with heart failure. In addition, the investigators will investigate pulmonary function, peripheral and respiratory muscle strength and quality of life. Methods: Heart failure patients (left ventricular ejection fraction < 40%) will be selected from the outpatient clinic of the myocardium of the Department of Cardiology of Unifesp and randomized among two groups: patients who will be submitted to placebo phototherapy and cycle ergometer exercise; and patients who will be submitted to active phototherapy and cycle ergometer exercise. All groups will receive treatment twice a week for four weeks. Patients will be instructed to conduct home-based walking program at least twice a week. Patients will be evaluated before and after protocols regarding the pulmonary function, peripheral and respiratory muscle strength, functionality, quality of life and evaluation of systemic inflammatory mediators.
This study aims to understand the interaction between school recess activity and duration and lunch choices among elementary school children
Considering that the failure of the treatment of obesity is justified by the multifactorial pathophysiology of this morbidity, the present project has the following hypotheses: 1. The occurrence of obesity is due to the derange,ent of mitochondrial energy metabolism ; 2. The unbalance is therapeutically modified through physical training ; 3. Obesity courses with the break-down in energy metabolism mitochondrial disease associated with systemic inflammatory characteristics that can be corrected through a combined long-term physical training program. This study have as objective : to analyse changes in mitochondrial function, inflammatory profile, oxidative stress and energy metabolism caused by concurrent physical training in obese women.
Two independent, but interrelated conditions that have a growing impact on healthy life expectancy and health care costs in developed nations are the age related loss of muscle mass (sarcopenia) and obesity. Sarcopenia affects approximately one third of adults over 60 years of age and more than 50% of those over 80 years, which is of concern when one considers that the most rapidly expanding population demographic in the UK is adults >80 years of age. Skeletal muscle is important in regulating blood glucose and insulin sensitivity. Thus, sarcopenia may play a role in exacerbating insulin resistance and progression toward Type II diabetes (T2D). Indeed, the highest incidence of T2D in the UK has been noted to occur in adults >65 years. Obesity is a major risk factor for chronic diseases including T2D and cardiovascular disease. Progression towards obesity is associated with a concomitant decrease in muscle mass, producing an unfavorable ratio of fat to muscle. Thus, obesity in old age may exacerbate the progression of sarcopenia. For the proposed study the investigators will conduct preliminary laboratory tests to characterize body composition, insulin sensitivity, systemic inflammation, aerobic capacity and muscle protein metabolism (in the fasted and fed state) in healthy older and obese older adults for comparison against healthy young individuals.
Physical activity (PA) in individuals with cystic fibrosis (CF) improves exercise capacity, slows decline in lung function, increases mucus clearance and improves health-related quality of life (HRQoL). Establishing and maintaining an exercise routine remains challenging and programs promoting PA in people with CF have poor participation. Moreover, while the positive effects of physical conditioning on lung function have been well reported, conventional measurements of lung function may lack the sensitivity to reveal improvement in mild lung disease. This randomized control trial (RCT; N = 60) evaluates the Do More, B'More, Live Fit, a 6-month fitness program designed to optimize exercise habits of 12-21 year-olds with CF through structured exercises with personalized coaching, exercise equipment including the FitBit Flex, online support and motivational messages delivered electronically. The intervention incorporates fitness preferences and encompasses endurance, strength and flexibility exercises while adjusting to physical fitness needs. The hypothesis is that intervention participants will have increased and sustained engagement and better health outcomes compared to control group participants. The investigators' specific aims are to: 1. Increase daily PA and measures of fitness 2. Improve lung clearance index (LCI) and participant HRQoL 3. Demonstrate feasibility, accessibility and satisfaction of intervention using semi-structured interviews The results of this pilot evaluation of the Do More, B'More, Live Fit program will offer novel insight into factors that sustain engagement in exercise programs and identify if LCI is an appropriate clinical outcome to assess PA interventions. Results will inform future RCT of interventions to optimize exercise habits of adolescents with CF.
The most important objective of this randomized controlled trial in subjects with increased cardiovascular and metabolic risk factors is to investigate whether only reduced daily sitting improves human cardiovascular and metabolic health during a six-month intervention. It is hypothesized and expected that only reduced sitting, without formal physical activity or exercise training, affects favorably cardiovascular and metabolic health.
Physical activity delays all-cause mortality in the general population and reduces the risk of cardiovascular disease (CVD), stroke, type-2 diabetes and some types of cancer (Garber et al., 2011). These diseases are associated with chronic inflammation, which is characterized by activation of inflammatory signalling pathways with abnormal production of cytokines and other mediators (Hotamisligil, 2006). Observational studies of large population cohorts have consistently shown an association between physical inactivity and low-grade systemic inflammation and interventional studies a reduction of inflammatory markers following exercise (Beavers et al., 2010). Chronic inflammation is also a predominant feature of treated human immunodeficiency virus (HIV) infection (Lederman et al., 2013; Deeks et al., 2013). Compared to age-matched HIV-negative subjects, persons with chronic HIV infection are at higher risk to develop non-acquired immune deficiency syndrome (AIDS) related chronic diseases (Guaraldi et al., 2011), and several studies have shown an association between chronic inflammation and higher cardiovascular risk and overall mortality (Kuller et al., 2008, Duprez et al., 2012). Recently, the investigators performed a pilot study of moderate physical activity that enrolled sedentary HIV infected subjects treated with combination antiretroviral treatment (cART), consisting of brisk walking, with or without strength exercise. Overall, after 12 weeks of training cholesterol profile and soluble and cell inflammatory markers improved significantly. However, because of the considerable individual variability in exercise responses, a program of physical activity needs be adjusted on an individual basis to be most effective. During recent years, the use of mobile technologies has been implemented for health monitoring interventions, including exercise. We hypothesized that the use of a mobile application will favour engagement to exercise by providing motivational inputs, and therefore adherence, and, as a consequence, an improvement of physical fitness. The investigators hypothesized that the use of a mobile application will favour engagement to exercise by providing motivational inputs, and therefore adherence, and, as a consequence, an improvement of physical fitness. Therefore, the aim of this project is to improve health and quality of life of patients living with HIV through self-empowerment by use of an innovative mobile application, in order to assist and monitor individualized program of physical activity and diet recommendation.
