Filter by:This pilot study will aid the development of a sonographic screening method used to obtain proxy measures of LBM and estimates of muscle composition that relate to Intramuscular adipose tissue (IMAT), lipid metabolism, and insulin resistance. Typically, age-related muscle loss is not assessed in older adults until they began to show signs of trouble managing their own lives independently. In addition to the loss of independence that is typically seen with diminished muscle mass and function (sarcopenia), age-related changes in lean body mass can have negative effects on insulin sensitivity. The investigators central hypothesis is that the muscle characteristics derived from ultrasound (US) will be significantly associated with estimates of dual energy X-ray absorptiometry (DXA) LBM, CT scan measures of IMAT, estimates of insulin homeostasis, and serum levels of inflammatory cytokines.
To compare the influence of a training program with Pilates and PNF methods to elderly women on the strength gains and motor control during voluntary contractions
The primary aim of the study is to evaluate consequences of frailty in critically ill patients. We hypothesize that a higher frailty index (based on published questionnaires) predicts a longer surgical intensive care unit and hospital length of stay, less ventilator-free days and a higher likelihood of an adverse discharge disposition. Our secondary aim is to identify muscle-size derived variables that can be used to predict frailty. We hypothesize that a low skeletal muscle mass measured by ultrasound can be used to quantify frailty, and to also predict the outcome of SICU patients, expressed as longer stay in the surgical intensive care unit and longer stay in the hospital, less ventilator-free days and a higher likelihood of an adverse discharge disposition. Our third aim is to examine potential triggers of muscle wasting in critically ill patients. Muscle wasting will be assessed by repetitive ultrasound measurements of muscle mass. We hypothesize that a significant decrease in skeletal muscle mass predicts longer stay at the surgical intensive care unit and longer hospital length of stay, less ventilator-free days and adverse discharge disposition.
The loss of muscle mass and strength due to aging leads to serious health problems for older adults. Muscle health can be improved by exercise training, but some people improve their strength substantially, whereas others improve little. The reason for this variation is unknown. This study will investigate whether function of the immune system influences how well people respond to exercise. Older Veterans who participate will have their muscle size, strength, and function measured periodically for almost a year. Participants will drink a nutritional supplement or placebo daily and complete a 36 session strength training program. Participants will be vaccinated for tetanus and donate small amounts of blood and muscle tissue during the study so that immune function can be compared to muscle outcomes during training and during a long-term follow-up. The study results should increase the investigators' understanding of the negative effects of aging on muscle and will possibly lead to better strategies for muscle maintenance and rehabilitation for older adults.
This study aims to assess usual walking speed (4-metre gait speed) and markers of sarcopenia predict mortality in patients with chronic respiratory disease.
In the present study, the effect of a bolus of intrinsically labeled milk directly after one-legged NMES (Neuromuscular Electrical Stimulation) will be studied under two conditions: during the day and prior to sleep
The purpose of this study is to provide information regarding potential factors underlying metabolic dysfunction, insulin resistance, and loss of muscle mass in aging muscle.
Pursuant to our previous longitudinal study (ClinicalTrials.gov ID: NCT02073370) in geriatric outpatients cooperated with the Department of Family Medicine, Department of Geriatrics and Gerontology, National Taiwan University Hospital, this study will be conducted to examine the impacts of the specific co-morbidities and ageing psychology on the outcomes of frailty/sarcopenia syndrome. The thresholds of specific chronic disease will be reviewed after frailty being considered in the elderly with co-morbidity condition. In addition, the conceptual framework and corresponding measuring instrument of "mental frailty" will be expected developed.
This project aims to assess the impact of technological processes of meat, as cooking conditions, on amino acid bioavailability and protein metabolism. The hypothesis is that, even if meat is considered as a good provider of fast proteins and so could be useful to prevent sarcopenia in aged people, the manner it is cooked can change its digestion rate and amino acids bioavailability for muscle synthesis.
The first goal of this study is the follow young and older people over a period of 8 weeks to define the processes responsible for loss of muscle length and width in age-related muscle wasting (sarcopenia) and allow us to look at age-related differences in tendon. Secondly, we will assess two different exercise interventions for reversing human sarcopenia; one which involves shortening of the muscle and the other which involves lengthening, whilst also studying why these exercises work the way they do. This project will have significant implications for our understanding of the control of skeletal muscle and tendon size in humans, particularly in relation to sarcopenia and the surrounding health issues.
