PURPOSE OF REVIEW: Trials of physical rehabilitation post critical illness have yet to deliver improved health-related quality of life in critical illness survivors. Muscle mass and strength are lost rapidly in critical illness and a proportion of patients continue to do so resulting in increased mortality and functional disability. Addressing this issue is therefore fundamental for recovery from critical illness. RECENT FINDINGS: Altered mitochondrial function occurs in the critically ill and is likely to result in decreased adenosine tri-phosphate (ATP) production...

Objective: Cardiac cachexia is a condition associated with heart failure, particularly in the elderly, and is characterized by loss of muscle mass with or without the loss of fat mass. Approximately 15% of elderly heart failure patients will eventually develop cardiac cachexia; such a diagnosis is closely associated with high morbidity and increased mortality. While the mechanism(s) involved in the progression of cardiac cachexia is incompletely established, certain factors appear to be contributory...

Duchenne muscular dystrophy is the most common and severe of the muscular dystrophies, a group of inherited myopathies caused by different genetic mutations leading to aberrant expression or complete absence of cytoskeletal proteins. Dystrophic muscles are prone to injury, and regenerate poorly after damage. Remorseless cycles of muscle fibre breakdown and incomplete repair lead to progressive and severe muscle wasting, weakness and premature death. Many other conditions are similarly characterized by muscle wasting, including sarcopenia, cancer cachexia, sepsis, denervation, burns, and chronic obstructive pulmonary disease...

General nutritional strategies to promote whole body protein retention, particularly with relation to exercise, have been largely based on adult research that does not consider the dynamic process of growth and often ignores scenarios commonly experienced by children (e.g., exercise in the heat). Therefore, the aim of the present review is to highlight the importance of post-exercise protein quantity and timing in active children, specifically with respect to the whole body protein turnover.

The practice of sport and medium-high intensity exercise increases the needs of energy and nutrients. Proper nutrition is very important for reaching the maximum performance, reducing the risk of injury, and ensuring the best recovery. It must also ensure the achievement of optimum nutritional status and prevent health problems at the present and in the future time. Eggs are a very nutritious food that can help athletes to achieve a correct diet. It contains proteins of high quality and bioavailability, a profile of fatty acids very favorable from the cardiovascular point of view, and vitamins and minerals involved in energy and protein metabolism, in defense against oxidative stress and inflammation, in cell growth and tissue repair...

PURPOSE: Major hepatic resections are performed for primary hepatobiliary malignancies, metastatic disease, and benign lesions. Patients with chronic liver disease, including cirrhosis and steatosis, are at an elevated risk of malnutrition and impaired strength and exercise capacity, deficits which cause increased risk of postoperative complications and mortality. The aims of this report are to discuss the pathophysiology of changes in nutrition, exercise capacity, and muscle strength in patient populations likely to require major hepatectomy, and review recommendations for preoperative evaluation and optimization...

Whey protein is a nutritional supplement commonly ingested for recovery following exercise. However, the timing when whey protein supplement must be ingested after muscle-damaging exercise is debatable. Therefore, the present study investigated the effects of the timing of supplement ingestion on muscle damage markers after eccentric or muscle-damaging exercise. In total, 32 collegiate male students participated in this study; they were randomly assigned to control group (n=8), before supplement group (n=8), after supplement group (n=8), or before and after supplement group (n=8)...

BACKGROUND: Athletes may complete consecutive exercise sessions with limited recovery time between bouts (e.g. ≤ 4 h). Nutritional strategies that optimise post-exercise recovery in these situations are therefore important. OBJECTIVE: This two-part review investigated the effect of consuming carbohydrate (CHO) and protein with water (W) following exercise on subsequent athletic (endurance/anaerobic exercise) performance. DATA SOURCES: Studies were identified by searching the online databases SPORTDiscus, PubMed, Web of Science and Scopus...

BACKGROUND & AIMS: β-hydroxy-β-methylbutyrate (HMB) is purported as a key nutritional supplement for the preservation of muscle mass in health, disease and as an ergogenic aid in exercise. Of the two available forms of HMB (calcium (Ca-HMB) salt or free acid (FA-HMB)) - differences in plasma bioavailability have been reported. We previously reported that ∼3 g oral FA-HMB increased muscle protein synthesis (MPS) and reduced muscle protein breakdown (MPB). The objective of the present study was to quantify muscle protein metabolism responses to oral Ca-HMB...

OBJECTIVES: Increasing protein or amino acid intake has been promoted as a promising strategy to increase muscle mass and strength in elderly people, however, long-term intervention studies show inconsistent findings. Therefore, we aim to determine the impact of protein or amino acid supplementation compared to placebo on muscle mass and strength in older adults by combining the results from published trials in a meta-analysis and pooled individual participant data analysis. DESIGN: We searched Medline and Cochrane databases and performed a meta-analysis on eight available trials on the effect of protein or amino acid supplementation on muscle mass and strength in older adults...

BACKGROUND AND AIM: Sarcopenia is a geriatric syndrome in which there is a decrease in muscle mass, muscle strength, and muscle function. Interleukin-15 (IL-15), a myokine released by skeletal muscle, has effects on both muscle and adipose tissue. We evaluated the relationship between plasma IL-15 level and sarcopenia. METHODS: We evaluated a total of 160 outpatient older people, and 80 of whom had sarcopenia. Sarcopenia was defined according to the European Working Group on Sarcopenia in Older People criteria...

PURPOSE OF REVIEW: To highlight the importance of nutrition in older adults undergoing a rehabilitation program. Geriatric rehabilitation aims at the recovery of physical abilities for a largely independent life in the community. The term 'geriatric rehabilitation' is wide and includes inpatient and ambulatory care as well as rehabilitation programs in hospitals, also outside geriatric wards. The role of nutrition is therefore not clearly defined, but an association between declined functional status and low nutritional status is evident...

PURPOSE OF REVIEW: To document recent evidence regarding the role of nutrition as an intervention for sarcopenia. RECENT FINDINGS: A review of seven randomized controlled trials (RCTs) on beta-hydroxy-beta-methylbutyrate (HMB) alone on muscle loss in 147 adults showed greater muscle mass gain in the intervention group, but no benefit in muscle strength and physical performance measures. Three other review articles examined nutrition and exercise as combined intervention, and suggest enhancement of benefits of exercise by nutrition supplements (energy, protein, vitamin D)...

Protein-energy malnourishment is commonly encountered in patients with end-stage liver disease who undergo liver transplantation. Malnutrition may further increase morbidity, mortality and costs in the post-transplantation setting. The importance of carefully assessing the nutritional status during the work-up of patients who are candidates for liver replacement is widely recognized. The metabolic abnormalities induced by liver failure render the conventional assessment of nutritional status to be challenging...

BACKGROUND & AIMS: Impaired anabolic responses to nutrition and exercise contribute to loss of skeletal muscle mass with ageing (sarcopenia). Here, we tested responses of muscle protein synthesis (MPS), in the under represented group of older women, to leucine-enriched essential amino acids (EAA) in comparison to a large bolus of whey protein (WP). METHODS: Twenty-four older women (65 ± 1 y) received (N = 8/group) 1.5 g leucine-enriched EAA supplements (LEAA_1...

BACKGROUND: Prostate cancer is the most commonly diagnosed cancer in men in developed countries. Androgen deprivation therapy (ADT) is a systemic treatment shown to increase survival in selected patients with prostate cancer. The use of ADT continues to increase for all stages and grades of prostate cancer despite known treatment-induced adverse effects. The primary aim of this study is to examine the efficacy of a targeted, multi-component resistance and impact-loading exercise programme together with a daily protein-, calcium- and vitamin D-enriched supplement on bone health in men treated with ADT for prostate cancer...

Numerous situations, such as the recovery from illness or rehabilitation after injury, necessitate a period of muscle disuse in otherwise healthy individuals. Even a few days of immobilization or bed rest can lead to substantial loss of skeletal muscle tissue and compromises metabolic health. The decline in muscle mass is largely attributed to a decline in postabsorptive and postprandial muscle protein synthesis rates. Re-introduction of some level of muscle contraction by the application of neuromuscular electrical stimulation (NMES) can augment both postabsorptive and postprandial muscle protein synthesis rates and, as such, prevent or attenuate muscle loss during short-term disuse in various clinical populations...
