Filter by:Patients with COPD are more inactive and more sedentary than subjects of the same age and patients with other chronic diseases. This inactivity and sedentary behavior is accentuated after hospitalizations due to a COPD exacerbation, and it increases the risk for future hospitalizations and mortality. Therefore, there is a need for intervention to promote physical activity and to reduce sedentary behavior after these events. The present study aims to evaluate the efficacy of a coaching program to promote physical activity and reduce sedentary behavior in patients with COPD who have suffered a hospitalization due to a COPD exacerbation. Sixty-six COPD patients admitted to the hospital will be recruited during 18 months. Physical activity, sedentary behaviors, as well as other clinical and functional parameters will be evaluated after hospital discharge. Patients will be then randomized to an intervention and control group (1:1). The intervention group will receive an individualized coaching program. During a motivational interview an experienced physiotherapist will asses participant's usual exercise habits, possible barriers and facilitators, self-efficacy and motivation to increase physical activity and reduce sedentary time. Based on these data (and baseline physical activity/sedentary information) an individualized, progressive program with specific goals setting and self-monitoring will be established (patients will be active participants and decision makers in this process). The control group will receive the usual care during follow-up. Physical activity, sedentary behaviors, as well as the clinical and functional variables will be evaluated again at 12 weeks in both patients' groups.
The aim is to examine the energy consumption before and after bariatric surgery. The study will contribute to the knowledge if operations should be complemented by interventions to increase energy expenditure, mainly by reducing sedentary. as input for the design of an intervention to reduce sedentary. Such intervention should be based on knowledge of the mediators of physical activity among the subjects that need to be strengthened.
Multiple studies have demonstrated a very low prevalence of women meeting physical activity and weight gain recommendations during pregnancy. Additionally, previous Blossom Project studies have shown that when pregnant women engage in a 20 minute walk each day, they spend significantly more time sitting in addition to longer bouts of sitting resulting in increased total sedentary time. We are going to test which method works best to decrease sitting time, and how those methods effect metabolic parameters such as insulin resistance and blood glucose. This study will consist of three groups, each utilizing a commercially available fitness tracker, Fitbit. Group 1 (SR): will reduce sedentary time by interrupting prolonged sitting. Group 2 (WALK): will reduce sedentary time via walking. Group 3 (UC): will continue on with their normal daily routine; usual care.
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.
Background: The interactions between human beings and wearable technology like activity trackers equipped with biometric sensors can be linked to health related new learning concepts/instructional methods supporting deep knowledge acquisition, situated, self-regulated and active learning. This personalized, long term interactions where specific information is pushed to the learner contributes to deepen the personal understanding related to the concept of and knowledge about health and has an impact on long term health action process. Design and methods: In order to understand the behavioural change process, a multiple case study including 35 higher education students in Hong Kong from an undergraduate course, BSc Exercise and Health is currently conducted. Each student uses a wearable device (activity tracker) over a period of five months, reflects weekly on emerging personal data, documents their thinking and action in the ePortfolio, and engages in an online forum. The participants enter their experiences with the biometric data, lifestyle adaptations (e.g. more steps), special situations (e.g. hike, heart rate changes during activity) and how these experiences lead to specific searches and actions on the web and/or in their real social network. The ePortfolio will allow the students to critically reflect on their progress and for the researchers to intervene at any time on the issues related to the participants' postings. EHealth literacy is used as indicator for the health action process of the participants. Evidence regarding change in eHealth at the beginning and end of the intervention will be collected with a standard questionnaire detecting eHealth their literacy scale. Scope: By reflecting on the information from their personal activity tracker and documenting it in their own ePortfolio, the students will continuously learn to analyse, search and critically assess health related personal and available digital information, organize it, present and discuss it with peers/tutor. This in turn will enhance critical thinking, raise questions about health related topics, stimulate further inquiry deepen their knowledge about personal health, inducing a healthier lifestyle.
Recent research suggests a majority of Hong Kong's toddlers (aged 2 to 4) are much less active than is recommended and are increasingly engaged in sedentary behaviour, which places them at risk of becoming overweight or obese. The proposed project will test whether connecting families to nature positively influences physical activity (that is, active playtime) and healthy eating routines in children aged 2 to 4. The investigators have recently conducted a pilot study Play & Grow (P&G), a programme based on the most successful international preschool interventions described in the literature. In addition to adopting healthy eating and physical activity intervention elements, the programme was enhanced by including a novel third element: connectedness to nature (CN). To test the effectiveness of this enhanced intervention, the plan is to run a family-based randomised controlled trial (RCT). The intervention will include 240 families with children aged 2 to 4, will take the form of one-hour activity sessions for parents and children held once a week for 10 weeks. The investigators will assess lifestyle-related habits before, immediately after the completion the intervention, at 6 months and one year after the intervention. Created for this purpose, a novel measuring tool for connectedness to nature, Nature Relatedness Scale (NRS), will be validated and tested for reliability prior to the RTC. The results of RCT are intended to be used to understand which components of the intervention were most effective. The objectives of this project will be achieved over a 36-month period, and it is expected to contribute to a close examination of key components of successful healthy lifestyle promotion programme during early childhood. The investigators predict that is that the new element CN will significantly improve the intervention. Finally, the overall aim is that connecting families to nature will result in sustainable lifestyle changes that remain with them for a lifetime.
This study involves a randomized controlled trial to test the feasibility, acceptability, and efficacy of a mobile health (mHealth)-enhanced physical activity (PA) intervention to increase daily bout-related and total moderate-intensity PA and to reduce sedentary behavior (SB) in non-physically impaired patients with ischemic stroke or transient ischemic attack (TIA).
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.
Exercise park equipments for the elderly are designed taking into account the physical and cognitive capabilities and needs of elderly individuals. These equipments are usually built in public spaces, and may be part of public health initiatives to promote active lifestyles in the elderly. Previous research has provided clear evidence on the short-term efficacy of exercise programs in improving physical function and level of physical activity in community-dwelling elderly. The goal of this randomized clinical trial is to assess whether an exercise intervention conducted in an exercise park equipment is able to achieve sustained improvements in physical function and level of physical activity, that are maintained for at least 3 months after the end of the intervention. The target population are community-dwelling elderly that are insufficiently active.
Previous studies have shown that subjects who play video games are prone to consume larger quantities of food than subjects who are simply resting. This is believed to be due to the development of a stress response in the video games group, resulting in increased fuel metabolism. However, it was shown that the energy intake of the two groups showed no correlation with the subjects' appetite/hunger, which was identical in both groups. The investigators propose to explore this issue further by comparing the effects of different types of video games on metabolism, using a randomized controlled trial. In this study, they will compare the stress levels, heart rate, blood pressure, appetite/mood, energy consumption, grip strength, memory and saliva cortisol, leptin and ghrelin levels of subjects playing (a) competitive and (b) problem-solving video games. Measurements will be taken preceding, during and after the 1 hour intervention. Following the intervention, participants will be offered savoury and sweet foods/drinks, which will allow us to assess their appetite preferences and caloric intake. The investigators first aim is to determine whether there is a significant difference in stress levels, eating habits and energy metabolism in the two groups. Our second aim is to determine whether there is a difference in glucose distribution to the muscles and brain between the two groups.
