Filter by:The investigators are doing a study to learn how to support patients aged 60+ in taking more breaks from sitting and reducing total sitting time. The goal of the study is to find out if a sitting time reduction intervention reduces sitting time compared with a control group.
At this time, no study has examined the effect of a lifestyle intervention with a reduced Sedentary Behavior (SB) prescription on overall physical activity, weight loss, metabolic dysfunction, and inflammation in breast cancer survivors. Thus, in collaboration with University of Tennessee Medical Center's (UTMC) Cancer Institute, investigators propose to randomize 30 female breast cancer survivors (history of breast cancer stages I [> 1 cm], II, or III) with a body mass index (BMI) between 25 and 45 kg/m2 who are sedentary (engage in > 8 hours a day of SB) and inactive (engage in < 100 min/wk MVPA) to one of three, 3-month conditions: 1. lifestyle intervention (Lifestyle) (increase MVPA to > 200 min/wk); 2. lifestyle intervention with a reduced SB prescription (Lifestyle+SB) (increase MVPA to > 200 min/wk and reduce SB by 2 hrs/day); or 3. weight management education materials provided via mailed newsletter (Newsletter). Lifestyle and Lifestyle+SB will receive a standard dietary (low-calorie [1200-1500 kcal/day], low-fat [<30% calories from fat]) prescription that emphasizes intake of fruits, vegetables, and whole grains, and a cognitive behavioral intervention to assist with meeting activity and diet goals. Dependent variables, measured at 0 and 3 months, include objectively measured SB, LPA, MVPA, and total activity via accelerometry; self-reported SB; percent weight loss; insulin and glucose, and leptin and C-reactive protein (CRP) (biomarkers of cancer prognosis that have been found to be positively related to SB and/or adiposity); diet; body composition; and fitness.
A theory-driven, web-based, computer-tailored advice to influence sitting at work was developed. The study investigated the effects of this computer-tailored intervention to influence workplace sitting on behavioural measures.
The investigators are doing a study to learn how to support patients aged 60+ in taking more breaks from sitting. The goal of the study is to find out if using commercially available devices are helpful in reducing sitting time.
The worldwide epidemic of physical inactivity is rising significantly and the main cause is sedentary lifestyle. In this era of globalization and rapid advancement of technology, people are chasing after worldly matters, leading them to abandon the most important factor in their life and that's their body. Most people are leading a sedentary lifestyle as they indulge themselves in their never-ending work. There is a significant lack of awareness on the importance of physical activity and cardiorespiratory fitness to health as people are focusing more on factors such as smoking, cholesterol and hypertension. The purpose of this study is to evaluate the effectiveness of stair climbing (SC) and 1 mile walking (1MW) in relation to cardiorespiratory responses and fitness.
This study will investigate the influence of increased sedentary time on long-term measures of muscle protein synthesis and metabolic health. The investigators will test the hypothesis that increased time spent in sedentary behaviours will lead to a reduction in long-term measures of muscle protein synthesis and compromised metabolic health.
The purpose of this study is to determine whether varying the frequency and length of activity breaks during the workday will differentially impact sedentary behavior and health outcomes. Participants will be randomly assigned to take short, frequent breaks (i.e., 1 minute every half hour) or longer, planned breaks (i.e., two 15-minute walks) from sitting during the workday. They will be instructed to follow the assigned protocols for an 8-week intervention and the effects of their participation on sedentary behavior and a variety of health outcomes will be assessed. The investigators anticipate participants in both intervention arms will demonstrate significant reductions in daily sitting time, bit do not have an a priori hypothesis regarding the relative effectiveness of each approach.
This study aims to investigate whether hourly prompts, delivered by Microsoft Office onto the PC's of office workers, is effective at reducing unhealthy patterns of sedentary behaviour .
The purpose of this study is to determine the individual and combined effectiveness of two smartphone-based tools for improving physical activity. The first is an individualized and guided goal-setting module, and the second uses "points", "levels", and "badges" to provide instant positive feedback throughout the program. It is hypothesized that both components will be effective, and greater effects will be noted for those receiving both components.
Introduction This study evaluates the effect on glucose, lipid and bone metabolism following knee orthopedic procedures in healthy and physically active individuals. The sedentary rehabilitation period following these procedures may impact negatively on glucose, lipid and bone metabolic pathways, whereas the more physically active rehabilitation period instituted 6 weeks after surgery is hypothesized to impact positively. Perspective This study will establish whether the well-known effects on glucose, lipid and bone metabolism of a sedentary lifestyle can be observed already following 6 weeks of physical inactivity in otherwise healthy and physically fit young and middle aged individuals. Investigators will thereby add knowledge to previous findings following strict bed-rest in healthy individuals on glucose, lipid and bone metabolism. In a clinical perspective it is important to examine the extent to which healthy individuals deteriorate in various metabolic pathways to better understand the pathophysiology behind these defects both in healthy individuals and in patients, who undergo bed rest or an equal reduction in physical activity as part of their rehabilitation. Study design 16 physical active non-diabetic individuals of age 18 - 50 years who are undergoing knee surgical procedures at the Arthroscopic Center at Amager/Hvidovre Hospitals are recruited as cases for this case-control study. 10 non-diabetic control subjects matched for age, gender and physical activity are recruited to establish a reference level. - The individuals will bring in morning spot urine for measurement of soluble urokinase plasminogen activating receptor (suPAR), creatinine, albumin and orosomucoid. Weight and height and waist and hip circumference will be measured. - Oral glucose tolerance test (OGTT) with ingestion of 75 g glucose during 5 min from baseline (0 min). Plasma for glucose, insulin, C-peptide, non-esterified fatty acid (NEFA) will be drawn - Before OGTT blood will be drawn for measurement of HbA1c, total cholesterol, LDL, HDL, triglyceride, Na, K, creatinine, hemoglobin (HgB), C-reactive protein (CRP), leukocytes, alanintransaminase (ALAT), alkaline phosphatase, Ca++, D vitamin, TSH, bone turnover markers (BTM), suPAR, interleukin 6 (IL6), TNFa, high-sensitivity C-reactive protein (hsCRP), lipid density profiling and lipid particle size. - Dual energy X-ray absorptiometry (DXA) of hip, lumbar columna, visceral and subcutaneous fat is measured by Hologic Discovery scanner.
