Filter by:It is well established that physical activity reduces the physiological effects of ageing. Among them, the decrease of the autonomic nervous system activity (ANS) is associated with the increase of cardiovascular events and sleep disorders occurence. It has been shown that high intensity cycle training can enhance the ANS activity by 30% in people aged of 70 years old. However, such trainings were done by old athletes used to train at intensities that could not be handled by nursing home elderly. Thus, an adapted activity such as brisk walking shall be defined to make it practicable for the many in convalescent homes. The investigators hypothesize that long term brisk walking training could lead to reactivate ANS in people living in convalescent homes.
This study will investigate the feasibility of an intervention to increase physical activity in pregnant women with diabetes by incorporating a brief in-person counseling session and Fitbit activity trackers into routine clinical care
This is a family based genotype-phenotype study designed to assess genetic and environmental influences on obesity, insulin resistance and beta cell function in the context of gestational diabetes.
This study examines the efficacy of a psycho-educational intervention program, AgingPLUS, with regard to increasing middle-aged and older adults' engagement in physical activity.
This is a 3-arm trial to compare exercise videogames versus traditional standard exercise using stationary bikes and treadmills versus a control condition. Results will examine minutes of physical activity at 12 weeks and 6 month follow up between conditions. We will also examine changes in indicators of cardiovascular health (e.g., body mass index, lipids) and changes in psychological factors that may be predictive of continued exercise engagement.
Introduction: The level of physical activity decreases progressively with age. Elderly subjects who are physically active have lower rates of morbidity and mortality when compared to those inactive. Hospitalization leads to long periods of bed rest and physical inactivity, with consequent muscle atrophy, generalized weakness, and decreased independence and functionality. Therefore, preventing inactivity, loss of muscle strength and the worsening of functional performance during hospitalization may be a way to avoid loss of independence. And while movement has been increasingly promoted as an important part of the recovery of hospitalized patients, many of them still spend much of the time bedridden while in hospital. Objectives: To evaluate the impact of a guiding program on the importance of remaining active during hospitalization in relation to the level of physical activity, functionality and muscular strength of elderly patients and to identify the main barriers that impede them to perform physical activities in the hospital environment. Methods: Randomized and controlled trial which will include elderly patients admitted to the Respiratory Diseases and Medical Clinic wards of the Institute of Medical Assistance to State Public Servants, in São Paulo. The intervention group will receive verbal guidelines and one booklet on the deleterious effects of hospitalization and the importance of staying active during hospitalization. All patients will be evaluated through accelerometry to identify the level of physical activity during hospitalization. Functionality will be evaluated through the DEMMI scale, muscular strength through handgrip and the main barriers to stay active during hospitalization by applying a questionnaire. The days of hospitalization and the clinical complications presented by the patients during the stay in the hospital will be noted. The difference of the outcomes of the level of physical activity and functionality before and after the intervention will be compared between the control and the intervention group through a t-test. The length of hospital stay will be analyzed by the Kaplan-Meier test and the incidence of complications by the chi-square test.
Dark chocolate (DC) is rich in epicatechin which augments nitric oxide (NO) production through endothelium-dependent influences. The increased bioavailability and activity of NO have been demonstrated to statistically increase flow-mediated dilation in healthy subjects and in hypertensive patients. DC supplementation has been hailed for its positive effects on cardiovascular health and it has been proposed as a booster of physical performance in athletes, however the mechanisms by which DC improves oxidative stress, vascular function and athletic performance are not fully understood. The investigators designed a human study assessing how DC improves NO bioavailability and activity in elite athletes. Twenty-four elite soccer players (aged 18-35 years old, all males) are divided in 2 groups and randomly assigned to receive DC (85% cocoa), 40g per day or white/milk chocolate (<35% cocoa) for 30 days. The primary outcome measure is the evaluation of Soluble NOX2-derived peptide (sNOX2-dp), a direct marker of NADPH oxidase activation. The secondary outcome measures are other markers of oxidative stress, as the soluble P-selectin (sPs), Vitamin E, soluble CD40 Ligand (sCD40L), a marker of in vivo platelet activation and flow-mediated dilation assessed by vascular ultrasound. All parameters are assessed at baseline and after 30 days in both groups.
Neuroscience evidence suggests that physical exercise can influence brain function and structure, both immediately and in the long-term. The 'Fit to Study' project is a randomised controlled trial to test the effects on academic performance (as well as fitness, wellbeing and cognitive function) of a teacher-training intervention designed to optimise the content of PE for brain and cognitive function during secondary school (Year 8) Physical Education (PE) lessons. The project aims to rigorously test the impact of this intervention in 100 state-funded secondary schools.
The aim of AS:Sk is to improve physical activity levels and health-related outcomes of children from the Skelmersdale area of West Lancashire through a school-based physical activity multi-component intervention.
This study examines the effect of 12-week strength training program with and without testosterone replacement therapy (TRT) on body composition, physical function, selected biochemical markers of metabolic health, molecular parameters of training adaptation and the quality of life patients with ADAM. The investigators believe, that strength training program performed 2 times per week for 12 weeks can improve body composition (decrease fat mass and gain lean mass), muscle strength, muscle power and general quality of life in all training groups. In addition, combination TRT and strength training could help decrease fat mass, improve BMI, cardio-respiratory fitness and thus provide optimal therapy combination for hypogonadal ageing males.
