Filter by:Currently there are very few studies that integrate classical interventions (screening clinics) and online tools in order to obtain sustainable lifestyle changes in workers efficiently. The current project aims to evaluate the efficiency of a combined approach versus the more traditional approach. Health Data collected by CAPSANA in the workplace between 2012 and 2014 showed that, out of 4231 workers, 69% should aim to do more active lifestyle and 74% to a better nutrition profile. In addition, 53% of the sampled population were overweight. In this context, the current project aims to motivate aims to motivate and follow individuals towards a healthier lifestyle. To do so, the Activate Your Health will be implemented and tested using various options (limited to more complete) in several companies.
It is generally accepted that chemical testing of biologic fluids is the most objective means of diagnosis of drug use. In recent years saliva has attracted much attention. The prime advantage of saliva is that it offers non-invasive, stress-free and real-time repeated sampling whereas blood collection is undesirable, difficult and expensive. In addition, it is known that androgens such as testosterone can be assayed in saliva, as these steroids pass the endothelial-epithelial barriers by passive diffusion. Nevertheless, the correlations of blood, urine and saliva concentrations are not well documented. In recent reviews, it is pointed out that salivary hormone analysis could be a promising method for sports medicine and doping control, but much work is needed before the use of saliva samples in this area receives the acceptance. According to recent studies the increase of testosterone concentration in saliva is significantly higher than alterations of steroid concentrations (or ratios) in blood or urine. Saliva concentration may therefore serve as screening parameter to select suspicious cases for further target evaluation (e.g. by IRMS). This may be beneficial to identify cases of transdermal administration of low steroid doses. It is therefore the aim of the present project to detect administered testosterone in saliva and compare these levels to those in blood and urine. The intention is not to detect high dosage but low dosage abuse of testosterone, as a single-dose by patch application. From the practical point of view saliva could offer a complementary specimen for a pre-screening of testosterone. So it could be assumed that salivary testosterone exceed upon plasma and/or urine levels. So the present study could be the base for a new method to preselect the suspicious samples for testosterone abuse.
Endothelial Progenitor Cells (EPCs) are circulating cells released from bone marrow which are important for maintaining cardiovascular health. The prevalence of cardiovascular disease in older adults is associated with reduced circulating EPC numbers. Studies have shown reduced EPC number and function in old vs. young individuals, and endurance exercise training increases EPC number and function in young adults. Oxidative stress adversely affects endothelial cells and preliminary evidence indicates that oxidative stress negatively affects EPC function. Conversely, regular exercise reduces markers of oxidative stress and may enhance EPC function in older adults. The investigators hypothesize that older endurance-trained athletes and matched sedentary individuals will have markedly divergent EPC function and that altering the physical activity levels of both groups will move them to intermediate points between these two extremes. The investigators also propose that the investigators can "mimic" the effect of exercise training on EPC function in cell culture by altering intracellular levels of a key enzyme and a signaling molecule which the investigators have shown to regulate EPC function with respect to exercise training in young individuals.
Increasing rates of sedentary living, often complemented by obesity, among large segments of the adult population are associated with costs to individual health and well-being and thereby to society as a whole. Although some workplaces offer physical activity opportunities, those employees who tend to need it the most (i.e., the health needy) are often not attracted. In this project, the investigators propose to develop and evaluate a programme that is targeted to the sedentary health needy employees. The investigators will work with the corporate partner (a large university) to attract such employees through an extensive social marketing driven campaign. A 16-week lunchtime walking programme is proposed in which walking groups are offered followed by support and motivational strategies for longer term independent walking. The investigators will examine the effects of the programme on total amount of walking (including a follow-up assessment 4 months later) and will use innovative technology (Smartphones) to also examine the effect of lunchtime walks on well-being and work performance within and between participants.
This is a randomized, controlled; single-blind parallel group trial carried out with hip fracture patients, starting at 12 weeks post fracture. Patients were approached during their acute stay in hospital, followed without any extra intervention for 12 weeks, and then randomized in a 2:1 manner to either intervention or control for the next 12 weeks. After the first 12 weeks intervention the intervention group were divided into two groups and randomized to an new single-blind parallel group trial for further intervention.
Over half of adults in this country are overweight. This increases risk for heart and blood pressure problems, cancer, stroke and arthritis. While it is difficult to lose large amounts of weight and keep it off, even small amounts of weight loss can improve health. Furthermore, fat is increasingly recognized as a source of substances that increase inflammation. It may be that some of the adverse consequences of being overweight are due to increased inflammation. We are asking you to volunteer for a research study in which you may lose a moderate amount of weight and increase your activity. It is important that you read and understand the information on this form. The purposes of these studies are to determine the influence(s) of age and body composition on the production of inflammatory chemicals by fat (adipose tissue), the mechanisms controlling this, and if a weight loss and aerobic exercise intervention results in a decrease in inflammation.
The purpose of this study is to investigate the effects of a series of Feldenkrais movement lessons on mobility and balance, particularly for older adults. The investigators hypothesise that mobility and balance will improve following the classes.
