Filter by:Research has shown that reducing the time spent sitting can reduce the risk of many diseases, such as diabetes and heart disease, and improve health. It is estimated that many older adults typically spend 70% of their waking day sitting, but little is known about whether reducing sitting promotes health and well-being in this age group. The aim of this research is to investigate the health effects of reducing sitting time by replacing it with short periods of standing or walking in adults over the age of 65.
As the loss of muscle mass with aging is associated with a dysregulation of muscle protein synthesis (MPS) that is generally characterized by an 'anabolic resistance' to nutrients, the primary outcome of the trial is to investigate the effect of a mixed macronutrient beverage on post-prandial myofibrillar MPS. However, the 'anabolic resistance' of aging may be predominantly influenced by the contractile activity of skeletal muscle; for example, the investigators have demonstrated that 2 weeks of reduced habitual activity (i.e. daily step count) induces anabolic resistance in otherwise healthy older adults. In contrast, resistance exercise is well-known to enhance muscle mass and can increase the sensitivity of skeletal muscle to dietary amino acids. Therefore, all participants will undergo a 2-week reduced step count intervention combined with a unilateral leg resistance exercise protocol to induce an 'unhealthy' or 'anabolically resistant' leg and a relatively 'healthy' or 'anabolically sensitive' leg, respectively; this within subject model will be utilized to investigate the effect of the mixed macronutrient beverage in both relatively 'healthy' and 'unhealthy' older muscle. The investigators will also measure changes in muscle mass, muscle function, and cardiovascular health of both legs before and after the 2-week intervention to determine the effect of reduced activity and the protective effect of minimal, low-intensity exercise on these outcomes.
This project will develop a novel collaborative treatment, based on the primary care behavioral consultation model and behavior therapy techniques including motivational interviewing and functional assessment, in which a patient, a Behavioral Health Consultant (BHC) and a HIV primary care provider share a unified plan targeting misuse of prescribed opioid analgesics in older HIV+ adults. The intervention will involve meetings between the BHC and the PCP, the BHC and the participant, and the BHC, PCP and the participant. Opioid misuse will be the primary outcome variable. Quality of the patient-provider relationship, pain, problematic use of other substances, antiretroviral adherence, and psychosocial functioning will be secondary outcomes.
The latest randomized controlled trials and systematic reviews of resistance training performed by older adults reported that the systematic use of exercise in machines improves muscle strength and power, functional abilities, body mass and body balance. However, the effect of resistance training with elastic tubes exercises have not been studied in all the variables described above. The objective of this study is to analyze the effects of elastic tubes exercises on muscle mass, muscle strength, functional performance and postural control in elderly untrained.
A 12-week multicomponent exercise is effective in improving executive function and gait performance in dual-task conditions.
As the aging population increases, preventing and decreasing disabilities become a critical issue for the health care system. Previous researches have shown that preventive community-based nursing services for older adults could achieve important health benefits at a relatively low cost. However, many frail and pre-frail older adults living in communities cannot get enough attention from current health care system. The role and function of nurses should be expanded to provide more comprehensive family-oriented care to improve health outcomes of older adults in Taiwan. The objectives of this study are: 1. Understand the difficulties and solutions for nurses providing community-based services in order to expand their better role and function. 2. Develop a cultural sensitive community advanced nurse service model for Taiwan in health care system. 3. Explore the effectiveness of community health programs by nurses for frail or pre-frail older adults in community. Focus groups and literature review will be used to achieve the first and second study objectives. A single centre randomized controlled trial will be used in this study to achieve the third study objective. Two hundred and twenty people aged 65 and over who meet the Fried definition of frailty and pre-frailty will be recruited from the clinic of a hospital. Participants will be followed for a 6-month period. Frailty, quality of life, satisfaction to the services, hospitalizations and admissions to nursing care facilities will be measured and compared between experimental group and control group. This research is an important step in the examination of a new approach to the community older people by nurses. The study results will provide the evidence data to recommendation for related policy making in the future.
WiiNWALK is a 4 week physical activity, with the intervention of a WiiFit, targeted to improve walking capacity in individuals with either a unilateral below-knee or above-knee amputation. This is a randomized control trial to evaluate the effectiveness of the WiiNWALK program in older (50+ years) community living adults with lower limb amputations (LLA). Hypothesis: We expect the WiiNWALK intervention will have a treatment effect with improvement in functional walking capacity, compared to the control group who will only be playing cognitive games. Secondarily, a functional walking capacity will also include an improvement in lower extremity strength and balance, inter-limb gait symmetry, balance confidence along with participation in daily and social activities, locomotor capabilities and an increase in physical activities.
The goal of this study is to evaluate the hypothesis that the addition of liraglutide, a long-acting glucagon-like peptide 1 (GLP-1) analogue, to a calorie-restricted diet will lead to greater weight loss than will a calorie-restricted diet alone in subjects who are older (50 to 60 years of age), overweight/obese, and prediabetic. These individuals have been selected for study because they are at greatly increased risk to develop type 2 diabetes (2DM) and cardiovascular disease (CVD), and it is hypothesized that the addition of liraglutide to a calorie-restricted diet will significantly decrease risk of these adverse outcomes. There is considerable evidence that GLP-I compounds, including liraglutide, improve glycemic control in patients with manifest 2DM. However, there is relatively little information as to the potential utility of these compounds in nondiabetic individual at greatly increased risk of 2DM and CVD. This research proposal is aimed at providing some of this information by quantifying the effects of liraglutide, a long-acting GLP-1 analogue, on weight loss, insulin secretion, insulin action, and multiple CVD risk factors in a very high risk group—older, overweight/obese, prediabetic individuals. Furthermore, by using specific methods, not surrogate estimates, and avoiding the confounding effects of glucotoxicity, it will be possible to gain new insights into the effects of GLP-1 on insulin secretion and insulin action.
The purpose of this interview study is to learn why adults would join a walking program. This study involves interviews with persons who are 65 years of age or older. The interview takes approximately 25 minutes. A total of 132 people will be enrolled. This study will examine the utility or value of various potential features of an incentive-based walking program. These data will enable us to monitor and improve upon enrollment of incentive-based walking programs.
The purpose of the present study is to evaluate the validity of 2 objective measures of physical activity among older adults. In addition, the investigators will examine the influence of functionality, walking aids, walking speed and step length on the accuracy.
