Filter by:Consumers are increasingly encouraged to consume more plant-based foods and lower their consumption of foods from animal origin. However, the consequences of such a transition on muscle mass still remains to be explored. This is of particular importance in the older population, where sarcopenia is highly prevalent. The aim of this randomized controlled cross-over study is to investigate the short-term effect of a 10-day controlled vegan diet on daily muscle fractional synthesis rates in comparison to a 10-day controlled omnivorous diet in 35 community-dwelling older adults. Participants will follow a fully controlled vegan diet, directly followed by a fully controlled omnivorous diet for 10 days, or vice versa. Researchers will compare the effect of the vegan diet to the effect of the omnivorous diet.
Fucoidan also ameliorates tumour and chemotherapy-induced muscle atrophy and -related cachectic symptoms in vivo and in vitro. To evaluate the effect of fucoidan in cancer cachexia or sarcopenia in cancer patients.
Aging is associated with a decline in muscle mass, strength, and physical function, leading to muscle mass loss and weakness. These concerns can impact an individual's functional independence and quality of life (QOL). Dietary protein stimulates muscle protein growth. Current studies suggest that optimal protein intake for older adults is greater than the Recommended Dietary Allowance. Barriers to consuming protein-rich foods in older adults include reductions in taste and smell, dentition, dexterity, and changes in living situation. Therefore, nutritional interventions are needed to effectively improve eating behaviors, diet quality, and stimulate muscle growth and strength. These interventions will help prevent, manage, and promote muscle mass loss recovery. Older adults may not be aware of their changing nutrient needs and therefore may lack the skills to prepare nutritionally adequate foods properly. Cooking demonstrations, or culinary medicine (CM), can help teach healthy cooking to reduce potential red meat consumption barriers and improve community-dwelling older adults' dietary habits. Thus, CM can be a novel strategy to improve diet quality in older adults and promote and augment at-home cooking. CM is an evidenced-base field that combines skills of preparing, cooking, and presenting food with the science of medicine. This field can help to accomplish potential eating behaviors and health outcome improvements. A tailored CM program can be an effective strategy that could reduce barriers in protein intake that will enable older adults to age well and productively.
this study aims to compare the effect of high-intensity resistance exercises measured using the 10-repetition maximum versus low-intensity aerobic exercises on muscle performance, physical function and quality of life in chronic kidney patients with sarcopenia who recently recovered from COVID-19 infection
Introduction： Muscle wasting is a serious complication that affects a large proportion of patients with heart failure (HF). Muscle wasting is a strong predictor of frailty and reduced survival in HF patients. Currently, standard treatments for slowing muscle loss in patients with HF are not available. The main intervention remains various types of physical activity programs. Telemonitoring is a promising strategy for improving heart failure outcomes by making it possible to monitor patients remotely. There are numerous examples of home-based exercise programs administered through telehealth services that have been beneficial for maintaining physical activity levels. These results highlight the potential utility of telehealth services for combatting sedentarism and muscle wasting among epidemic and post-epidemic phases. Objective： The purpose of this study is to evaluate the effect of a multi-component physical activity program based on home telemonitoring on patients with heart failure and muscle wasting. Methods： This study used an quasi-experimental study, two-group repeated measurement design. The experimental group received the Home-based exercise with telemonitoring and control group according to regular nursing care. Data were collected at baseline (T0), and post-tests will be conducted right after the intervention period (T1). Additionally, detraining effects will be measured 12 weeks after program cessation (T2) . Data were collected including demographic questionnaire, sarcopenia, cachexia assessment, clinical blood parameters from patient record, physical activity, loneliness, and quality of life. Scientific or Clinical Implication of the Expected Results： The study results can be used to design designated interventions and provide information for policymaking.
The retrospective cohort study will compare the prevalence of sarcopenia and associated factors between older patients who have undergone bariatric surgery and older patients with obesity without previous bariatric surgery.
This research study is comparing the effect of traditional standardized, subjective auto-regulated, and objective auto-regulated resistance training on physiological adaptations and performance measures in adults aged 50 years or older. Traditional standardized resistance training involves prescribing resistance training as a percentage of an individual's one-repetition maximum (i.e., the maximal weight they can lift one time). Auto-regulated resistance training involves adjusting resistance training based on an individual's performance during the session. Subjective auto-regulation involves the resistance trainee providing a subjective rating of perceived exertion based on repetitions in reserve (on a scale from 1 - 10) to adjust the resistance training prescription. A rating of perceived exertion of 10 would mean that the resistance trainee believes that they have provided maximal effort and believes that they could not have performed an additional repetition during the set nor increased the load. Objective auto-regulation involves adjusting the resistance training prescription from a linear position transducer (a device that has a string that attaches to the barbell and provides a velocity value on each repetition). A slower velocity value means a higher perceived exertion and load used, whereas a faster velocity value means a lower perceived exertion and load used.
Dietary proteins potently augment muscle protein synthesis. Because of poorer anabolic sensitivity with ageing, studies and guidelines recommend higher dietary protein intake for older adults. Although higher doses would benefit skeletal muscle remodelling, large protein consumption is not feasible for many older adults. To circumvent, high-protein quality which possesses a high amino acid profile and digestibility appears to have an emergent role for supporting anabolism. Since currently the best line of defence against age related muscle loss is resistance exercise training and regular protein consumption, emphasising high-quality protein ingestion, such as whey protein, within meals may be feasible and efficacious in supporting musculoskeletal remodelling in older adults, without requirement for large protein doses. The investigators propose that at low doses, high quality protein will have additive benefit to muscle protein synthesis compared to low-quality protein. Further, combining high-quality protein diets with resistance exercise training will have more profound benefits for muscle protein synthesis and muscle remodelling more so than low-quality protein diets.
Inflammatory bowel disease (IBD) includes two idiopathic chronic relapsing and remitting inflammatory conditions affecting the gastrointestinal (GI) tract: Crohn's disease (CD) and ulcerative colitis (UC)Malnutrition and significant alteration of body composition are common in inflammatory bowel disease patients, whereby the prevalence of malnutrition may be up to 82.8% in CD patients with active disease, and up to 38.9% in CD patients in remission. Many CD patients have low muscle mass and function (sarcopenia) with drivers of such pathophysiology unknown. 41.6% of CD patients with sarcopenia require surgery, with the surgical trauma and resulting inactivity leading to further muscle mass loss such that the chronic inflammatory insult associated with refractory disease may be linked to advanced muscle mass depletion. The majority of adult CD patients have low muscle mass even in clinical remission indicating the poorly reversible nature of this phenomenon. Chronic disease burden may therefore be important in the accentuation of muscle loss. Muscle mass is maintained through the daily balance of MPS and muscle protein breakdown (MPB), with the essential amino acid (EAA) components of a meal and muscle contraction being the primary stimulators of MPS. Patients with active CD show a significant decrease in the expression of proteins in hypertrophic signalling pathways (Akt, P70S6K1) with no change in the expression of atrophic signalling (MAFbx, MuRF1). Also, adult CD patients with established disease consume less protein compared to matched healthy volunteers (HV). Furthermore, the intestinal motility, measured using cine-MRI, is reduced in active CD, possibly further decreasing intestinal digestion and absorption of dietary peptides. In general, the malabsorption is a major contributing factor to malnourishment in CD. It has been shown that in male paediatric patients with long-term CD, muscle metabolism is perturbed by a negative branched-chain amino acid balance in the forearm, with this variable linked to lower appendicular muscle mass, higher muscle fatigue and reduced protein intake, CD may have a significant effect on protein digestion and absorption, and blunt the MPS response to feeding, leading to a chronic muscle mass reduction that may persist even when in remission. The EAA components of a protein meal are crucial for the stimulation of muscle protein synthesis (MPS), and all the EAA/leucine play a key role in driving MPS. Low serum levels EAA/leucine have been reported in CD but their role in the aetiology of sarcopenia in CD is unknown. Further, how CD affects the protein digestion/absorption and how this contributes to low EAA/leucine unclear. Recent advances in stable isotope tracer techniques using a dual tracer methodology now enable a more accurate determination of protein digestibility. By following the appearance of intrinsically labelled AAs into the blood upon digestion of the intrinsically labelled protein, alongside the appearance of label-free AAs, protein digestibility can be accurately determined. Further, by collecting a muscle biopsy postprandially, the direct incorporation of AA from the digested protein into the muscle can be determined- providing a gold standard method for investigating anabolic resistance. Project aim is to use an intrinsically labelled casein to investigate protein digestion, absorption and MPS responses in CD patients. To achieve this, investigators will investigate protein digestion, absorption and muscle protein synthesis responses in Crohn's disease patients and healthy volunteers by utilising intrinsically labelled protein.
Sarcopenia is one of the major causes of functional decline and negative health outcomes among older adults. Prominent evidence suggests exercise interventions can reverse sarcopenia. However, past studies mainly focus on structured exercise programs, automatically excluding many older adults who are not motivated and lack the time/resources to conduct the structural exercise. Therefore, we propose to examine the effect of the Sarcopenia Translation functional Exercise Program (the STEP program) on community-dwelling older adults. The STEP is a functional exercise program designed to address low motivation and other time/resources barriers for rapid translation in community settings. The 12-week STEP program teaches older adults to apply functional exercise activities incorporating resistant training principles in their daily routines. With a dual focus apriori in assessing clinical effectiveness and potential implementation strategies for future community implementations, we will conduct a single-blind randomized control trial among 60 community-dwelling older adults at risk or with sarcopenia. The study's purposes are threefold: (1) to assess the effect of the functional exercise intervention compared to usual care on primary outcomes of sarcopenia (muscle strength, muscle mass, and physical function); (2) to assess the long-term effects of the functional exercise intervention on primary outcomes of sarcopenia; (3) explore potential implementation strategies for rapid community implementation including development of a communityappropriate protocol for tracking long-term effects such as metabolomic biomarkers. This study aims to develop an effective functional exercise program as an alternative to structured exercise programs. Additionally, the goal is to accelerate the translation of the functional exercise program for older adults at risk or with sarcopenia in real-world settings.
