Filter by:The purpose of this study is to investigate mechanisms underlying the reduction in muscle quality (the ratio between muscle strength and muscle size) with aging, and to investigate how these factors are affected by strength training and protein supplementation. It is already established that muscle quality defined as the ratio between the strength and the size of a muscle is improved with strength training, even in frail elderly individuals. However, the relative contribution of factors such as activation level, fat infiltration, muscle architecture and single fiber function is unknown. The main focus of this study is to investigate the relationship between muscle quality and muscle protein breakdown, as insufficient degradation of proteins is hypothesized to negatively affect muscle quality.
Spondylarthropathies (SpA) are among the most common chronic inflammatory rheumatisms in adults, responsible for a muscular loss or sarcopenia which can be very disabling, not much documented in the literature, and not yet studied in France. In addition, sarcopenia is associated with decreased physical activity and increased risk of falls and fractures. A better characterization of the determinants of this muscular loss will allow to better detect and take care of it. The aim is to conduct the first French study on the prevalence and severity of sarcopenia in patients with spondyloarthropathies and to study the variables that may be associated with it. Finally, we propose to evaluate obesity related to sarcopenia in these patients and compare them to cases matched for age and sex (from OFELY / STRAMBO cohorts, Lyon, FRANCE). This is a prospective interventional and monocentric study with minimal risks and constraints: patients will be included for one day for an evaluation of their sarcopenia by measuring their muscle strength, physical performance and body composition and recording of their socio-demographic and disease characteristics.
The development of a low-grade, chronic, systemic inflammation observed in the elderly (inflammaing) has been associated with increased risk for skeletal muscle wasting, strength loss and functional impairments. According to studies performed in animals and cell cultures increased concentrations of pro-inflammatory cytokines such as IL-6 and TNF-α as well as increased levels of hs-CRP lead to elevated protein degradation through proteasome activation and reduced muscle protein synthesis (MPS) via downregulation of the Akt-mTOR signaling pathway. However, evidence regarding the effects of inflammaging on skeletal muscle mass in humans is lacking. Thus, the present study will compare proteasome activation and the protein synthetic response in the fasted and postprandial period between older adults with increased systemic inflammation and their healthy control counterparts.
The aim of this randomised, double-blind, placebo-controlled, parallel groups trial is to investigate the effects of 12 weeks resistance exercise and whey protein supplementation on energy metabolism, markers of appetite, inflammation and hormonal response and body composition and strength and functional performance. Generally healthy, retired men aged 60-80 years will be recruited (n = 52 in total, n = 13 per group). Participants will be randomised to either: a) control group, b) whey protein supplement group, c) resistance exercise + control group or d) resistance exercise + whey protein supplementation group.
Cirrhosis is a late stage of hepatic fibrosis caused by many forms of liver diseases and conditions, such as hepatitis and chronic alcoholism. The World Health Organization (WHO) has reported that this condition accounts for 1.8% of all deaths in Europe (170,000 deaths/year). Patients with cirrhosis are characterized by severe metabolic alterations, which converge in a malnutritional state. Malnutrition encompasses glucose intolerance, chronic inflammation, altered gut microbiota, reduced muscle mass (sarcopenia), as well as loss and dysregulation of adipose tissue (adipopenia). Malnutrition is the most frequent complication that adversely affects the outcomes of cirrhotic patients. Yet, despite its clinical repercussions and potential reversibility, there are no effective therapies because our limited understanding of the mechanisms underlying this altered metabolism. β-hydroxy β-methylbutyrate (HMB) is a naturally produced substance regarded as safe and effective in preventing muscle loss during chronic diseases. Previous studies have indicated some beneficial effects of HMB itself or its parent metabolite, leucine, on adipose tissue, glucose intolerance, inflammation, and gut microbiota. This study aims to translate those beneficial effects to cirrhotic patients. The investigators hypothesize that HMB can improve cirrhosis-related metabolic abnormalities through its pleiotropic effects. The goals of this study are: i) to perform a randomized clinical trial to evaluate the efficacy of HMB, administered as nutritional supplementation, on clinical symptoms of cirrhosis. ii) to uncover the precise metabolic pathways that underlie HMB action, with a special focus on muscle, adipose tissue, and gut microbiota.
As the proportion of older adults increases, elderly-related issues attract more attention. Sarcopenia is one of the popular elderly-related issues. Sarcopenia may induce decreased muscle strength, poor physical activity, even disability and increase rate of hospitalization and mortality. Therefore, we want to figure out the management for decreasing prevalence of sarcopenia in older adults. This trial is planned to perform during 2017/08/01~2017/12/31. We plan to enroll 60 elderlies who are sarcopenia. These patient will be divided into 2 group randomize. Experimental group will be received a set of exercise, composed by warm-up, strengthening training with a towel, cold-down, 60 minutes per time, 3 times per week. Control group will be suggested home-based walking activity. We will evaluate the patient's functional performance three times, before training, after training, post-training for three months, respectively. These results will be analyzed by repeated measure ANOVA.
A research study regarding the body's response to several weeks of training using short sprints and pomegranate juice supplementation
Sarcopenia is an independent predictor of morbidity and mortality in cirrhotic patient before and after liver transplantation. Beta-hydroxy-beta-methyl butyrate (HMB) is a leucine metabolite with potential efficacy in increasing protein synthesis, muscle mass and its functionality. The aim of this randomized controlled study is to evaluate the effect of a nutritional supplementation with HMB after liver transplantation both on muscle mass and on muscle function.
This pilot study aims to investigate whether high intensity interval training can result in rapid improvements in physical fitness amongst the frail elderly (over 70 years old). Participants will undergo a wide range of physical fitness measures followed by a four week exercise protocol. Determination of improvement will be by repeated testing of the physical measures taken for baseline. The primary outcome measure will be anaerobic threshold. There will also be a subgroup of participants who will undergo muscle biopsy and D2O ingestion to allow an insight into the mechanistic basis behind exercise training response in this age group.
This randomized, double-blind, placebo-controlled supplementation trial tested the hypothesis that nutritional supplementation with muscle-target nutritional supplementation concurrent with regular, controlled physical activity would increase the efficacy of physical rehabilitation in old adults suffering from sarcopenia
