Filter by:Project 2 of the University of California, San Diego (UCSD) American Heart Association (AHA) Women's Health Program will assess 3-month changes in sitting time, standing time, physical activity and blood pressure in a randomized control trial (RCT). This 2-arm RCT will occur in the community with post menopausal Latina women (N=250) who spend at least 8 hrs/day sitting and have increased risk for cardiovascular disease through high BMI and other cardiometabolic risk factors. Women will be identified through the San Ysidro Health Center and assessed at the South Bay Latino Research Center.
In adults, the sedentary behavior was related to cardiovascular risk markers, regardless of the level of physical activity (PA). However, the interruption of prolonged sedentary time has shown positive results even when performed in breaks of low intensity and short duration of activity. The aim of this study is to analyze the influence of a sedentary uninterrupted period, as well as different forms of breaks in sedentary time for the glycemic, insulin and inflammatory markers responses in older adults. This is a controlled clinical trial to be conducted in older (≥ 65 years) and sedentary (<150 min / week of moderate to vigorous physical activity) people. Those with BMI ≥ to 35.00 kg /m2; diabetic, on medication for glycemic control, or with absolute or relative contraindications to PA practice will not be included . Participants will undergo four phases of intervention separated by an interval of 7 days: (1) Prolonged Sitting Time(PST), in which older people will stay for 5 hours seated; (2) Prolonged sitting with PA of light intensity and short duration (LiSd), time sitting is interrupted for PA bouts of 50-60% of the Heart Rate (HR)max; (3) Prolonged sitting with PA of moderate intensity and short duration (MiSd), time sitting will be interrupted for PA bouts of 65-75% predicted HR max; (4) Prolonged sitting with PA of moderate intensity and long duration (MiLd,) time sitting will be interrupted with PA bouts of 65-75% of HRmax. PA bouts will be performed by walking into a hallway every 20 minutes of sitting time and will last 2 minutes, except in MiLd phase (10 minute breaks every 75 minutes). To evaluate the effects of different PA interruptions in plasma glucose, serum insulin and inflammatory markers, blood samples will be collected serially (-30min, Baseline and 30min, 1h, 2h, 3h, 4h and 5h after a standardized meal. It is expect that interruption of sedentary time, even with breaks of short duration and light intensity can bring benefits to cardiovascular risk markers even in the elderly.
African Americans are at a substantially greater type 2 diabetes risk compared to Caucasians; however, very little data are available on the effects of exercise training on type 2 diabetes risk factors in at risk African Americans. The present proposal will evaluate the effects of 6 months of moderate versus vigorous intensity aerobic exercise training on fitness, insulin sensitivity, mitochondrial capacity, skeletal muscle oxidative/insulin sensitivity markers, adiposity, and quality of life in African Americans.
The overall goal of this study is to test personalized mobile phone-based physical activity interventions among staff members at the University of California, Berkeley. Most physical fitness applications for smartphones and activity trackers use a constant goal for the number of steps each day. However, if the step goals are dynamically adjusted according to past behavior, then the corresponding goals may encourage individuals to increase their physical activity level. This study consists of a randomized controlled trial in which we are assessing the efficacy of two different algorithms for calculating personalized goals for the number of steps each day.
This study aims to describe the pattern of active and sedentary time in survivors of a critical illness, at three time points during their hospital admission (awakening in the ICU after ≥ 5 days of mechanical ventilation, discharge to ward and discharge from hospital). The specific research objectives are to 1. Determine the duration of active and sedentary parameters including time and bouts in 24 hour periods 2. Examine changes in the active and sedentary parameters including time and bouts between time points of awakening and both ICU and hospital discharge. 3. Conduct a preliminary examination of relationships between activity and sedentary behaviour metrics with measures of muscle strength, physical function and hospital length of stay.
Prolonged sitting is a risk factor for cardiovascular and musculoskeletal diseases, diabetes, several types of cancer and all-cause mortality. In combination with static and awkward postures, the prevalence of musculoskeletal diseases can increase further. Although the implementation of sit-to-stand or active workstations can help to reduce sitting time, improve physical activity at work and promote health benefits, it might also lead to changes in cognitive functions such as productivity. The purpose of this study is to evaluate the short-term effect of alternating working postures on cognitive performance for healthy people.
The study of the behavior of the mechanisms of body balance with a workout based on the Pilates method can facilitate the development of more accurate rehabilitation approaches. However, there is still little scientific information on its effects on the locomotor system and it's necessary to search for new methods to evaluate its strategies more specifically. Thus, this study aims to determine whether an exercise program based on Pilates method has influence on the static and dynamic postural balance of sedentary adults. This is a randomized controlled trial, which will be developed with an initial sample of 20 subjects of both sexes, aged between 18 and 30 years, divided into two groups: a control group and an experimental group. Participants with physical activity time up to 150 minutes per week will be included, assessed by the International Physical Activity Questionnaire (IPAQ), and those who have no experience with the Pilates method. In the experimental group a workout program will be done for 6 weeks with individual classes including exercises based on the Pilates method, during 1-hour, twice a week. Assessments will be made prior and after the training program with anamnesis, anthropometric measurements and also the Balance Error Scoring System and the Star Excursion Balance Test Y to assess postural balance. During the tests and training program exercises the muscle activity of paraspinals and transversus abdominis will be analyzed using surface electromyography (sEMG), and body mass center displacement will be measured with a triaxial accelerometer positioned on the fifth lumbar vertebra. The data will be entered in a spreadsheet and statistically tested with SPSS software. The tests will include the comparison of means, association, correlation and effect size, which will be chosen according to the distribution of the data and will use the 5% significance level for all tests.

The main purpose of this study is to evaluate the effectiveness and the maintenance of a behavior change program called VAMOS (Active Life Improving Health) Program on physical activity and healthy eating habits in different environmental contexts of Florianópolis/ SC/ Brazil. This study will be conducted in Health Centers (HC) of Florianópolis/ SC/ Brazil, defined according to environmental and income characteristics. Therefore, initially all geographic areas around the HC will be visited to classify the public places as favorable (with the presence of spaces for the practice of PA) and unfavorable environmental (do not have spaces for physical activity). Thereafter, four HC will be selected: high income + high environmental quality index, high income + low environmental quality index, low income + high environmental quality index, low income + low environmental quality index. In each HC, the volunteers will be randomly assigned into two groups of approximately 25 people: VAMOS group and control group. The participants that will be assigned to the VAMOS group will participate in a behavioral change program aimed at motivating changes in physical activity and eating habits during five months (12 meetings - six weekly meetings and six fortnightly meetings), while the control group will receive one educational lecture regarding lifestyle changes. The meetings of VAMOS Program will be held in the dependences or nearby the HC and will be mediated by the physical education professional previously trained. The Program will be evaluated by the RE-AIM framework: reach, effectiveness, adoption, implementation and maintenance. The effectiveness will be assessed from measurements of physical activity, eating habits, self-efficacy, social support, quality of life, anthropometry, and lipid profile before and after five months of intervention. The implementation will be assessed by identifying the extent to which the program will be conducted as planned. The maintenance will be estimated from revaluations of all outcomes, as measured before and after the intervention, six months and one year after the end of the program.
The purpose of the study is to see if one's liking and awareness of different types of activities is related to one's activity pattern.
