Filter by:This study will evaluate the efficacy of an exercise-based contingency management (CM) intervention. A total of 120 substance abusing patients in intensive outpatient treatment will be randomly assigned to one of two conditions: (a) standard care plus CM for completing goal-related activities not related to exercising (e.g., improving work, family, or transportation issues), or (b) standard care plus CM for completing exercise-related activities. Compared to those receiving goal-related CM activity contracting, it is expected that those in the exercise CM condition will participate in more physical activities and develop greater strength and flexibility, decrease drug use, reduce HIV risk behaviors, lessen depressive symptoms, and improve health indices.
The purpose of this study is to gather ECG data during normal activity, exercise, and sleep from normal subjects with or without well-controlled epilepsy. This normal subject data will serve as "true negative" (i.e., no seizure occurring) challenge data for testing cardiac based seizure detection algorithms.
Anxiety and depression are often present in patients with chronic heart failure (CHF). This study aimed to evaluate the influence of anxiety and depression on the physical function, disability, and quality of life (QOL) in CHF. This study examined the effects of 8-week home-based exercise on these parameters, and investigated the correlations between these outcome changes.
Contingency Management (CM) is highly effective in promoting recovery from substance use disorders, but benefits tend to attenuate over time when CM is discontinued. Identifying modifications of CM delivery that can extend its benefits is an important goal. The goal of this study is to evaluate the use of reinforcements to increase physical activity, specifically walking. The study provides a standard CM intervention to promote walking for three weeks. After three weeks, a progressively increasing variable interval schedule of reinforcement will be evaluated for increasing the durability of effects of the initial CM intervention. We hypothesize that Variable Interval Prize Contingency Management will result in greater adherence to a walking goal of 10,000 steps per day at Week 15 and Week 24 compared to the Control Condition.
Until now it has been assumed that regular endurance training has a positive influence on cardiac function and that the positive effect increases with increasing intensity. However, little is known about the effects of intense endurance stress on the heart. According to current knowledge repeated exposure to strenuous endurance activity may lead to minor but possibly irreversible damage to the heart with resultant scarring of the heart's muscle. Within this study we attempt to find out by different analytical methods - in particular magnetic resonance imaging (MRI) and ultrasound of the heart - to what extent the heart muscle is affected by an intense endurance exercise, i.e. the "Jungfrau-Marathon", and which changes can possibly be found. Due to repeated measurements we will obtain further information on the short-term course of possible changes. Hypotheses: A single bout of prolonged strenuous exercise (PSE) leads to transient alteration in cardiac function accompanied by the appearance of biomarkers for myocardial damage.
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.
In the present study the microdialysis method is used to investigate biochemical changes within and around the joint simultaneously in both the resting state and in a joint that had been subjected to exercise. The aim of the present study was, by applying the microdialysis technique, to monitor markers of cartilage breakdown and inflammation in 2 different positions of the knee (inside and in the inner part of the knee capsule) in a group of human females with knee osteoarthritis over a period of 3 hours.
The objective of this randomized controlled trial was to evaluate the effects of two different physical exercise programs aimed at long-term lifestyle changes in physical activity in patients with Type 2 Diabetes, with glucose metabolism evaluated by HbA1c as the primary outcome.
