Filter by:This proposed prospective study will evaluate whether a novel exercise approach, seated vibration therapy, can improve function in the target population of older adults. Therefore, the primary aim of this pilot is to examine the effect of vibration therapy on muscle function (balance, muscle power and strength) and muscle mass.
Extending quality of life and attenuating functional decline is paramount in older adults. This study investigates the effects of low-intensity power-training in older women and its effects on functional outcomes.
Forty physically active men and women aged 18-45y will take part in an 8-week resistance training program, randomized (double blind) 1:1 into each of two groups. Twenty participants will be randomized to receive 60 g/d of hemp powder (containing approximately 40 g protein and 9 g oil) supplementation and 20 randomized to receive 60 g/d of soy supplementation (matched to the hemp for macronutrients and calories) during eight weeks of training. Each participant will complete testing before and after the intervention for assessment of body composition (lean tissue, fat, and bone mass), strength, central fatigue, markers of inflammation, and bone resorption. Over the 8-weeks of training, participants will train four-five days per week for 1-1.5 hours per session with exercises targeting all major muscle groups. The training will involve a "two day split" where different muscle groups are trained on two consecutive days (day 1 involves chest, back, and arms; day 2 legs, shoulders, and abdominals). Resistance training will provide the necessary stimulus for protein synthesis to optimize the effect of a protein-containing nutritional supplement. The hemp or soy powder will be consumed in two doses (i.e. 30 g powder containing 20 g protein per dose) immediately after exercise sessions and one hour after exercise. This dosing regimen is optimal for stimulating muscle protein synthesis and building muscle mass . On the one non-training day per week the two doses will be consumed with meals.
The focus is healthy ageing, i.e. delaying the deterioration in health status in older adults. Loss of lean tissue (skeletal muscle) mass, a process termed sarcopenia, or bone tissue mass, a process called osteopenia, is a consequence of aging per se, modified by nutrition and lifestyle behaviour. The aim is to conduct a study of body composition, physical activity, muscle function and ability to undertake activities of daily living in older Irish men and women and to investigate the effect of a six month period of nutrient support, or nutrient plus physical activity on lean tissue mass and function and bone mass in men and women aged 50 to 70 years.
Background to the research: Sarcopenia is a geriatric syndrome defined by progressive generalised loss of skeletal muscle, mass, force and function. Problem statement and objectives: To validate a simple, reproducible, screening tool, which is easy to use in the general practitioner's surgery is one of the challenges of the future. The primary objective is to assess the sensitivity and specificity of the study screening test, the SARC-F, at a predetermined threshold of >= 4. A total score of >=4 is associated with poor physical performance and is also predictive of the clinical diagnosis of the disease. The secondary objectives are to assess the prevalence of sarcopenia in the study population, to carry out a subgroup analysis of statistical performance for the five questions tested by the SARC-F, to identify the main risk factors associated with the disease and to propose an algorithm, positioning the SARC-F at the heart of a systematic screening process for the disease. Materials and methods: This is a diagnostic, cross-sectional study with a descriptive and analytical epidemiological component to analyse the secondary endpoints. It will be carried out in usual care over a period of 6 months in a homogeneous population of 65-year-old and older patients from the community consulting in primary care. The subjects will undergo the screening test (SARC-F questionnaire) and then the reference clinical assessment (gold standard) in succession. Expected results: To demonstrate the statistical tests that the SARC-F questionnaire is a simple tool, appropriate for early screening of sarcopenia in primary care.
This extension study was a 24-week off-drug follow-up of the core CBYM338E2202 (NCT ) study and the main objective was to determine the long-term durability of bimagrumab (BYM338) effect after a 6-month treatment period.
This study aims to determine whether vitamin D3 supplementation is any more effective in improving musculoskeletal function when combined with exercise training compared with exercise training alone.
Resistance training has shown the most promise among interventions aimed to combat aging muscle atrophy as it enhances strength, power, and mobility function, but induces varying degrees of skeletal muscle hypertrophy as the investigators demonstrated in the initial 5-year funding period of this award (2001-2006). In the subsequent 5-year funding period (2007-2012), the investigators built on this prior work by using a dose-response approach in older adults - ultimately to optimize the treatment of age-related muscle atrophy. The investigators tested four, long-term resistance training prescriptions in older (60-75 yr) women and men to determine which prescription maximizes mechanisms driving muscle regrowth. One of the innovations in this project was the use of a 4-wk pre-training program to reach a plateau in the early, non-muscle mass adaptations, thereby establishing a true baseline from which both mechanisms of measurable muscle hypertrophy and functional consequences of hypertrophy could be studied in a tightly integrated fashion without bias in the subsequent experimental period. A randomized design was used to test the overarching hypothesis that a novel program of mixed strength and power training would optimize the anabolic environment to promote muscle hypertrophy and robust gains in performance. This hypothesis was tested with three specific aims.
The purpose of this pilot study is to investigate the feasibility and potential impact of a combined resistance exercise and increased protein intake intervention in (frail) elderly, in a real-life setting.
A thorough characterization of glucose metabolism and "inflammaging" in elderly subjects will help determine to what extent each of these factors affects muscle mass/function and contributes to age-related muscle wasting. The investigators will correlate patterns of insulin secretion/sensitivity with "muscle "quality/quantity" in diabetic and non-diabetic elderlies (≥70 years old). By comparing different groups (healthy, sarcopenic, diabetic, diabetic/sarcopenic), the investigators expect to identify an "oxidative/inflammatory signature" (e.g., circulating interleukins/myokines, plasma antioxidant capacity) specific for the sarcopenic phenotype and related to muscle insulin resistance.
