Filter by:This randomized controlled intervention study in institutionalized elderly investigates the effect of 6 months of local vibration therapy applied on the thigh and hip on muscle strength, muscle mass, bone density, and functionality.
Loss of skeletal muscle strength and skeletal muscle mass occurs with of aging. This are-related decline in skeletal muscle mass and skeletal muscle strength is a major underlying factor contributing to many of the metabolic disorders and frailty of the investigators rapidly expanding aging population. Endurance (aerobic) and resistance exercise training programs have been shown to effectively reverse the age-related decline in metabolic and contractile muscle functions. The investigators will measure synthesis rates of individual muscle proteins in 36 each of young (18-30 yrs) and 36 older (> 65 yrs) people to determine their response to 8 weeks each of endurance, resistance, combined endurance and resistance training, or placebo exercise training. Hypotheses. 1. to measure fractional synthesis rates of multiple muscle proteins and identify those that are enhanced by an endurance exercise program 2. to determine whether changes in protein synthesis in response to endurance exercise programs are dependent on age 3. to measure fractional muscle synthesis rates of multiple muscle proteins and to identify those that are enhanced by a resistance exercise program 4. to determine whether changes in protein synthesis in response to resistance exercise programs are dependent on age
Sarcopenia is known to be associated with loss in muscle mass that results from a reduced number of muscle fibres, an atrophy of remaining muscle fibres, and an increased infiltration of non-contractile tissue (collagen, fat). Accentuated by cancer and treatments, sarcopenia impairs muscle function resulting in a higher risk of physical disability and death. The commonly used test for sarcopenia screening consists in a DEXA (Dual energy X-ray absorptiometry) scan. However, this test can't provide structural muscle information. In contrast, the mechanical properties of muscle tissue can be explored using an acoustic radiation force impulse (ARFI). The question remains whether muscle sonoelastography using ARFI imaging could be helpful for sarcopenia screening. For this, volunteers will be recruited in three groups: ≤ 30 years (Gr A) and ≥ 70years, both without any serious chronic disease, and patients ≥ 70 years presenting curative cares for cancer (Gr C). The volunteers belonging to the groups A and B will be followed during one day. The patients included in the group C will be followed during 6 months. For this latter group; the first visit (t0) will take place before treatment and the second visit will take place 6 months later (t6months) Volunteers will have clinical examinations (weight, stature, BMI, performance status/ ECOG) and will be evaluated on their nutritional status (MNA-SF, 24h dietary recall) and physical capacities (IPAQ, SPPB, lower limb muscle strength, 6-min walk test, QLQ-C30 items relative to the fatigue symptom).
Muscle proteins accumulate damage during aging and leads to the loss of muscle mass and function in older people. Exercise can increase the making of new proteins and removal of older proteins, but it is not known if the effect changes with aging or type of exercise. The investigators will determine the ability for endurance, resistance, or a combination of exercise training to remove older-damaged proteins and make newer-functional muscle proteins in groups of younger and older people. The investigators will particularly study protein that are involved with energy production (mitochondrial proteins) and force production (contractile proteins). Hypothesis 1: Older people will have greater accumulation of damaged proteins than younger people. Hypothesis 2: Aerobic exercise will decrease the accumulation of damaged forms of contractile and mitochondrial proteins in younger and older people. Hypothesis 3: Resistance exercise will decrease the accumulation of damaged forms of contractile proteins in younger and older people.
Sarcopenia is the loss of muscle mass and function that accompanies aging. The term sarcopenia comes from the Greek "sarx" (flesh) and "penia" (loss). Sarcopenia is a topic of great interest to geriatricians, and from 2010 discussing the possibility of considering it as a geriatric syndrome. Diagnostic criteria are reduced muscle mass, reduced strength and impaired physical performance. The presence of muscle mass reduction set presarcopenia diagnosis, when combined with one of the other two are talking about sarcopenia and when are the three is defined as severe sarcopenia. The hypothesis of our study is that sarcopenia is highly prevalent in older people with hip fracture. The increase in inflammatory indices of older people, along with bed rest, represent factors that accelerate the development of sarcopenia. These factors together could be the base of the high percentage of patients who do not recover the degree of autonomy before the fracture.
1. RATIONALE The unique characteristic of our study lies in the attempt to reverse the functional impairment experienced by sarcopenic patients with hip fracture using nutritional intervention. What makes this study different from prior studies is that it will be conducted in a hospital setting, unlike most prior studies, which were conducted in a community setting. The association between muscle mass and strength, inflammatory indices, and functional impairment versus dependence and fragility will also be measured. 2. HYPOTHESIS The hypothesis of our study is that nutritional intervention enriched in metabolites of essential amino acids (beta-hydroxy-beta-methylbutyrate) is effective for treating sarcopenia in elderly patients with hip fracture and improves functional level. 3. OBJECTIVES Primary objective is to assess functional improvement after nutritional intervention in sarcopenic patients with hip fracture, as measured using Barthel index. Secondary objectives will include: 1) to show the relationship between metabolic and inflammatory indices and sarcopenia; 2) to show how sarcopenia and its treatment influence the risk of fall; 3) to show muscle mass improvement; 4) to show increased strength; 5) to assess mortality and morbidity. 4. EXPECTED RESULTS The investigators expect to find that the supplemented group experiences throughout the study period a significant improvement in functional status (Barthel index), an increase in muscle mass, and a reduction in fat mass. An increased strength and a reduction in associated complications (falls) are also expected. The investigators hope to be able to show reductions in inflammatory indices and insulin resistance. To conclude, by improving muscle strength and mass the investigators expect to find a reduction in the disability and dependence of this population group.
This study is designed to assess the effect of a diet-controlled nutrition program utilizing an egg-based higher protein diet on muscle composition and size, and indices of metabolic health and markers of systemic inflammation in older men and women who are slightly overweight.
The purpose of this study is to examine the effect of omega-3 fatty acid supplementation on changes in muscle mass, muscular strength and physical function.
Although there is some evidence that whole body electromyostimulation(WB-EMS) affect bone via its acute and longitudinal effects on muscle mass and strength, the corresponding impact on bone density and falls in older adults has not been assessed yet. The investigators hypothesize that WB-EMS significantly affects bone parameters as assessed by DXA, and significantly reduce fall rate and ratio in a cohort of frail elderly women.
The purpose of this study is to determine whether a prolonged (9 month) high (6g/d) of marine oil improves insulin sensitivity and glucose control in subjects with impaired glucose regulation.
