Filter by:Humans lose muscle and strength as they get older. Further, ageing is accompanied by loss in cognitive function. It is not quite clear why this happens; however, it is known that the loss of muscle and strength can increase risk for physical and mental health risks and impair the ability of older people to remain physically independent. Weight lifting and proper nutrition, particularly eating high quality protein at the proper time and quantity, may help prevent these losses when a person gets older. To determine if regular beef consumption as part of a higher protein diet aids the muscle adaptive response to resistance training and improvements in cognition, seventy healthy individuals will be recruited to lift weights 3 times a week for 10 weeks. One group (n=36) will consume the Recommended Dietary Allowance (RDA) for protein (0.8g/kg/day), while the other group (n=36) will consume an amount twice the RDA (1.6g/kg/day), which is in agreement with recommendations from the American College of Sports Medicine. Participants will have their muscle strength tested and samples of blood and muscles will be collected before and after training to determine how the muscle adaptive response to resistance exercise is affected by higher protein intake. In addition, participants will undergo cognitive assessments at baseline and follow-up to determine the influence of improving muscle strength on attention and memory. Overall, the investigators proposed study will use sensitive methodology to determine if providing protein above the RDA and at optimal times during the day in combination with a weight lifting program can help make someone stronger and build larger muscles than someone consuming the RDA, as well as what processes may be responsible for helping the muscles to get bigger and stronger.
Many detrimental effects of aging have been identified in the human voice, most of which are accepted as "normal". However, age-related vocal deficits disrupt communication and decrease quality of life in older adults and may be preventable and/or treatable through behavioral interventions. The objective of this proposal is to determine the effectiveness of a technology-assisted vocal exercise intervention on the vocal function and quality of life in older adults. Forty older adults (65+) will be recruited and randomly assigned to either an app or PDF-delivered vocal training intervention lasting 8 weeks. Pre- and post-testing involving vocal functioning assessments, as well as mobility, psychosocial, and cognitive functioning assessments will be conducted. This interdisciplinary project will enhance the investigators understanding of physical, mental, and social health-related quality of life among older adults.
Physical activity (PA) has physical, emotional, and cognitive benefits for seniors (e.g., increased strength and balance, reduced frailty, fewer falls, improved brain function, lower mortality risk), yet many seniors have limited access to exercise options due to numerous barriers (e.g., transportation concerns, financial costs, fear of injury/falling). This project will overcome common exercise barriers by creating an interactive web-enabled TV program (i.e., Smart TV), adapted from research-based PA protocols, to be implemented in an Independent Living Facility (ILF) setting. A web-based prototype will be developed, and ILF residents and administrators will be able to create, use, and evaluate a customizable exercise program tailored to the individual's preferred type of exercise, intensity, and duration.
Knee osteoarthritis is one of the most common pathologies in old people, and the leading cause of pain and disability. Symptoms include joint pain, stiffness, limited mobility, functional impairment and proprioceptive deficit. When conservative treatments fail to control these symptoms, a total knee replacement (TKR) is the chosen treatment, mainly because of its efficacy on pain relief. In recent decades, this surgical procedure has been soared, and it has also aroused the interest of researches about the patients' outcomes after surgery. Despite the TKR results in good reported outcomes, after surgery patients may manifest persistent pain and problems affecting to their functionality, stability, walking speed, proprioception, motor control, risk of falling and therefore to their quality of life. In more than a third of the cases, those deficiencies may be extended after surgery from six months to one year, when subjects use to achieve the plateau functional values. Traditional rehabilitation programs have been usually focused on improving muscle strength of the lower limbs as well as the functionality with specific exercises to achieve this purpose, and to a lesser extent on balance and proprioception exercises. Evidence supports this approach. Yet, task-oriented rehabilitation focusing on balance enhancement may be one of the most important factors for a complete rehabilitation, since benefits of proprioceptive and balance trainings may range from better stability and motor control, improvements in both static and dynamic balance and enhanced functionality. Indeed, recent studies have shown that the combination of traditional functional rehabilitation together with balance training may help to restore functional deficits to a larger extent than usual therapy, and based on a systematic review published (Moutzori, 2015) and in our previous works (Roig, 2016), sensori-motor training is an acceptable adjust to usual physiotherapy care . Looking into the effect of preoperative trainings or education before TKR surgery, it is aimed at improving the physical function, but also managing the expectations of the surgery for a better recovery. There is from low to moderate evidence about the effects of TKR pre-interventional training programs, and some authors have argued that the effects are too small to be consider clinically relevant. In general, the preoperative program is usually focused on functional and strengthening exercises. Despite of proprioception is used in the clinical practice for the prevention and recovery of many orthopedics injuries, the amount of evidence about the effects of proprioceptive training programs for knee and hip replacement is not large, few works compares pre-habilitation and post-rehabilitation programs, and there is not systematically reviewed evidence reporting the efficacy of balance and proprioceptive pre-interventional training programs. In this framework, this aimed at evaluating the effects of specific-task oriented proprioceptive and balance training programs when conducted by patients undergoing TKR before and after surgery, and will compare these effects to the outcomes achieved with traditional strength-functional programs, as well as to no specific prehabilitation training.
In a recent randomized, double-blind, cross-over clinical trial, serum growth hormone (hGH) increased 682% above baseline 120 minutes after oral administration of an amino acid-based dietary supplement (SeroVital), p=0.01 vs placebo. In contrast to the mechanism of hGH stimulation by ghrelin, the investigators hypothesize that the supplement suppresses somatostatin, a know inhibitor of both hGH and TSH. To test this hypothesis, the investigators measured triiodothyronine (T3) after administration of the amino acid-base supplement.
Individuals of advanced age with cardiovascular disease are at higher risk of fall.The aim of this study is to explore the effect of specific exercise program based on balance and coordination on stability parameters
This study will begin to assess the association between perceived stress and enhanced aging in persons living with HIV (PLWH). The investigators suspect this relationship may be mediated by increased aging within the immune system and subsequent low-level inflammation that commonly leads to multiple illnesses and frailty as one ages. The findings from this study will identify potential diagnostic and therapeutic targets to improve the health of aging PLWH which could also apply to HIV-uninfected populations.
The increasing prevalence of Alzheimer's disease and other forms of dementia causes new challenges to ensure that healthcare decisions are informed by research evidence and reflect what is important for seniors and their caregivers. Primary care providers point to a need for more training on communication with families of seniors living with dementia, and on the non-pharmacological health options that are often recommended before use of medications.Therefore, the investigators will design and evaluate an intervention to train primary healthcare providers on how to empower seniors with dementia and their caregivers in making health-related decisions based on research evidence and on their preferences and priorities. A distance professional training program on shared decision making will initially be designed, comprising evidence summaries to be shared with patients living with dementia and their caregivers who face difficult decisions. Patients with dementia, their caregivers and healthcare providers, will then provide feedback on the training program, which will then be improved following their suggestions. In a last step, the investigators will study the processes required to implement this training program and measure its effects on provider knowledge and intention to adopt shared decision making.
The investigators are studying the effects of acarbose on muscle and adipose gene transcription in older adults.
The purpose of this study is to investigate whether a comprehensive group education combined with a lifestyle "activation" program that includes (a) sleep hygiene course, (b) physical activity promotion, and (c) bright light therapy, can improve both sleep quality and cognitive function among 96 community-dwelling older adults.
