When we age, we lose muscle. It is not exactly clear why this happens, but we do know that this muscle loss can increase health risks and lead to health problems. Lifting weights (i.e. performing resistance exercise) and proper nutrition, in particular eating enough high quality protein, can help slow the loss of muscle mass or potentially even reverse it. Protein and resistance exercise are thought to do this by stimulating your muscle to make more proteins and/or potentially ...

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 multiple markers of sarcopenia in older men. 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 [placebo only], b) whey protein supplement group, c) resistance exercise + placebo group or...
The aim of this study is to investigate the amino acid kinetics in blood after a bout of strength training and ingestion of different milk protein supplements (native whey, whey protein concentrate 80, hydrolysed whey, microparticulated whey and milk) The investigators hypothesize that native whey will give a faster and higher rise in blood concentrations of leucine compared to the other milk protein supplements.
The purpose of the study is to examine the effects of consuming protein supplement (whey) compared to whole milk immediately after bouts of resistance training on muscular strength and body composition.
This research study is looking at the effects of a whey protein nutritional supplement on changes in muscle mass, strength and physical function in response to a 6 month program of strength training exercise.
Sarcopenia, a progressive loss of muscle mass, strength and function, is an inevitable natural process of aging. While it may be impossible to completely reverse the progress of sarcopenia, it is well established that intake of dietary protein through essential amino acids (EAAs) and whey protein increases anabolic response. The current study will test if a specially formulated mixture of EAAs and whey protein can maximally stimulate anabolic responses at the levels of whole bo...
The focus is performance nutrition. Resistance exercise can induce low level muscle damage in conjunction with impaired contractile function. Milk-derived proteins contain, or induce, bioactive properties that assist muscle recovery and restore/improve muscle function. The aim of the research is the recovery of muscle function following resistance exercise. In this study, the investigators propose to undertake a comparison of the ingestion of two milk-derived protein-based rec...
The main purpose of the present study was to investigate the effects of whey protein supplementation associated with resistance training on muscle strength, body composition, muscle quality, cellular hydration, cardiometabolic risk factors, inflammatory and oxidative stress markers in trained elderly women and to evaluate whether the timing of protein intake provide different responses on these variables.
Muscle protein synthesis can be stimulated by ingestion of protein sources, such as whey, casein or soy. Protein supplementation can be useful to restore protein turnover after exercise but also to preserve skeletal muscle mass and function in aging adults. Ingestion of large doses of essential amino acids (EAA) or certain protein supplements may be an effective strategy to induce muscle protein synthesis. However, in many cases, it may not be practical or feasible to consume a...
Gut hormones have therapeutic potential in the prevention and treatment obesity and type 2 diabetes (T2D). Rodent evidence suggests that calcium may potentiate the effects of protein ingestion on gut hormone secretion. Evidence in humans however, is lacking. This study aims to assess whether the addition of calcium to protein ingestion augments postprandial gut hormone availability in humans.
The aim of this study is to investigate potential protein synthesis effects of whey protein high in leucine compared to whey protein with normal leucin content in fragile elderly patients in a acute crossover setting. We will use the method of a 2 X 3 h tracer infusing protocol with 15Nphenylalanine along with blood samples and muscle biopsies.
This study was designed to obtain information about the change in postprandial amino acids in blood over time, after consumption of different dairy products with varying proportions of whey protein and caseins, and different processing conditions.
The aim of this project is to investigate the potential benefits of combining a new protein beef hydrolysates extract with a regular endurance training programme on (a) body composition (b) performance (c) muscle structure (d) blood markers of health in athletes. As a second objective the investigators will analyse potential differences obtained from the ingestion of the new hydrolysates beef protein extract compared to the ingestion of others commercially available protein sou...
Obesity has numerous comorbidities that are associated with exceedingly high healthcare costs. In addition to well- characterized impairments in lipid and glucose metabolism, obesity is associated with altered protein metabolism. We have recently observed that obese individuals are essentially nonresponsive to protein ingestion with respect to myofibrillar protein synthesis. This suggests that skeletal muscle remodeling in obese individuals is impaired possibly contributing to ...
The current study will investigate the effect if whey protein on postprandial glycaemia and appetite in type II diabetics, assessing incretin (GLP-1, GIP), insulin, and appetite control (leptin, PYY3-36) hormone responses.
Resistance exercise training is a known stimulant for muscle protein synthesis (MPS) to occur, however the consumption of protein is also necessary to induce a shift towards a positive net protein balance. Other nutrients have been shown to be useful in the accretion of lean body mass and strength. Whey protein has been shown to improve muscle net protein balance after resistance exercise, more so when in conjunction with creatine. Furthermore, essential amino acids such as Leu...
This study compares three different protein supplements (casein, whey and leucine-enriched whey) and their effect on post-inflammatory muscle waste in a model of acute disease. Each test person will undergo all three interventions. It is believed that leucine is the primary driver of muscle protein synthesis and therefore we hypothesize that leucine-enriched whey and whey are superior to casein in combating post-inflammatory muscle waste, because of its higher leucine content ...
Gut hormones have therapeutic potential in the prevention and treatment obesity and type 2 diabetes (T2D). Milk protein and calcium can each potentiate gut hormones following meal ingestion in humans. However, these nutrients may interact synergistically (and with other minerals in milk) such that specific co-ingestion of these nutrients is required to obtain the full therapeutic potential for metabolism and energy balance. This proposal is to perform a pilot study on the effec...
The purpose of this study was to determine the effects of L-leucine (LEU) or different protein supplements standardized to LEU (~3.0 g/serving) on changes in body composition, strength, and histological attributes in skeletal muscle and adipose tissue. Seventy-five untrained, college-aged males (mean±SE; age=21±1 yr, body mass=79.2±0.3 kg) were randomly assigned to an isocaloric, lipid-, and organoleptically-matched maltodextrin placebo (PLA, n=15), LEU (n=14), whey protein ...
This study evaluated the effect of protein intake immediately after resistance exercise on lean mass, strength, and functional capacity gains in postmenopausal women. Participants were randomly assigned to protein-carbohydrate group (PC) (n=17), that ingested 30 g of whey protein immediately after exercise and 30 g of maltodextrin in the afternoon; and to carbohydrate-protein group (CP) (n=17), that ingested 30 g of maltodextrin immediately after exercise and 30 g of whey prote...
To investigate the impact of supplementing fermented Mailard reacted whey protein (F-MRP) on natural killer (NK) cell activity, circulating cytokines and serum protein levels.
The aim of this study is the first aim of a NIH project that consists of 3 aims. The first aim examines the acute effects of two high-quality milk proteins (casein vs. whey) on whole-body and muscle protein metabolism in COPD patients with severe loss of muscle mass and the effects of adding leucine. The principal endpoints will be the extent of stimulation of net whole body protein synthesis as this is the principal mechanism by which either amino acid or protein intake causes...
