Myprotein Impact Whey Protein Powder. Muscle Building Supplements for Everyday Workout with Essential Amino Acid and Glutamine. Vegetarian, Low Fat and Carb Content - Vanilla, 2.5kg

Product Information

Acute protein doses should strive to contain 700–3000 mg of leucine and/or a higher relative leucine content, in addition to a balanced array of the essential amino acids (EAAs). A review by Bosse and Dixon [ 84] critically summarized the available literature on protein supplementation during resistance exercise and hypothesized that protein intake may need to increase by as much as 59% above baseline levels for significant changes in fat-free mass to occur. Finally, it should be noted that for many athletes, consuming a post- or pre-workout protein-containing meal represents a feeding opportunity with little downside, since there is no benefit from not consuming protein pre- and/or post-exercise. In other words, not consuming protein-containing foods/supplements post-exercise is a strategy that provides no benefit whatsoever. Thus, the most practical recommendation is to have athletes consume a meal during the post-workout (or pre-workout) time period since it may either help or have a neutral effect.

I've got the vanilla flavour and it tastes nice. A little much with milk due to the egg white powder so water is best to have with it. Really fills you up so between meals I'll have my shake with an apple which is helping me keep lean. It's protein amount per serving is huge so work out alot and see the results. Milk proteins have undergone extensive research related to their potential roles in augmenting adaptations from exercise training [ 86, 93]. For example, consuming milk following exercise has been demonstrated to accelerate recovery from muscle damaging exercise [ 162], increase glycogen replenishment [ 163], improve hydration status [ 162, 164], and improve protein balance to favor synthesis [ 86, 93], ultimately resulting in increased gains in both neuromuscular strength and skeletal muscle hypertrophy [ 93]. Moreover, milk protein contains the highest score on the PDCAAS rating system, and in general contains the greatest density of leucine [ 156]. Milk can be fractionated into two protein classes, casein and whey. Comparison of the quality of whey and casein reveal that these two proteins routinely contain the highest leucine content of all other protein sources at 11% and 9.3%, respectively. While both are high in quality, the two differ in the rate at which they digest as well as the impact they have on protein metabolism [ 165, 166, 167]. Whey protein is water soluble, mixes easily, and is rapidly digested [ 168]. In contrast, casein is water insoluble, coagulates in the gut and is digested more slowly than whey protein [ 168]. Casein also has intrinsic properties such as opioid peptides, which effectively slow gastric motility [ 168]. Original research investigating the effects of digestion rate was conducted by Boirie, Dangin and colleagues [ 165, 166, 167]. These researchers gave a 30g bolus of whey protein and a 43g bolus of casein protein to subjects on separate occasions and measured amino acid levels for several hours after ingestion. They reported that the whey protein condition displayed robust hyperaminoacidemia 100min after administration. However, by 300min, amino acid concentrations had returned to baseline. In contrast, the casein condition resulted in a slow increase in amino acid concentrations, which remained elevated above baseline after 300min. Over the study duration, casein produced a greater whole body leucine balance than the whey protein condition, leading the researcher to suggest that prolonged, moderate hyperaminoacidemia is more effective at stimulating increases in whole body protein anabolism than a robust, short lasting hyperaminoacidemia. An acute exercise stimulus, particularly resistance exercise, and protein ingestion both stimulate muscle protein synthesis (MPS) and are synergistic when protein consumption occurs before or after resistance exercise.

I love the taste of the protein! After reading up about types of protein I realised that I needed casein protein so when I saw the sample of the strawberry cream on offer I bought a couple of them to try. Skeletal muscle is sensitized to the effects of protein and amino acids for up to 24h after completion of a bout of resistance exercise. A high protein diet (3.4g/kg/d) combined with a heavy resistance training program improves body composition in healthy trained men and women – a follow-up investigation - PMC Aspiring female physique athletes are often encouraged to ingest relatively high levels of dietary protein in conjunction with their resistance training programs. However, there is little to no research investigating higher versus lower protein intakes in this population. This study examined the influence of a high versus low-protein diet in conjunction with an 8-week resistance training program in this population. A total of 17 females (21.2 ± 2.1 years; 165.1 ± 5.1 cm; 61 ± 6.1 kg) were randomly assigned to a high-protein diet (HP: 2.5 g·kg -1·day -1; n = 8) or a low-protein diet (LP: 0.9 g·kg -1·day -1, n = 9) and were assessed for body composition and maximal strength prior to and after the 8-week protein intake and exercise intervention. Fat-free mass increased significantly more in the HP group as compared with the LP group (p = .009), going from 47.1 ± 4.5 to 49.2 ± 5.4 kg (+2.1 kg) and from 48.1 ± 2.7 to 48.7 ± 2 kg (+0.6 kg) in the HP and LP groups, respectively. Fat mass significantly decreased over time in the HP group (14.1 ± 3.6 to 13.0 ± 3.3 kg; p < .01), but no change was observed in the LP group (13.2 ± 3.7 to 12.5 ± 3.0 kg). Although maximal strength significantly increased in both groups, there were no differences in strength improvements between the two groups. In aspiring female physique athletes, a higher protein diet is superior to a lower protein diet in terms of increasing fat-free mass in conjunction with a resistance training program.

The extent to which protein supplementation, in conjunction with resistance training, enhances maximal strength is contingent upon many factors, including: In a systematic review, the results of clinical studies on the influence of a single protein or amino acid administration on muscle protein synthesis in younger and older people are summarized (middle-aged persons ≥55 vs. 18-35 years). Eight of 21 studies showed significant differences between younger and older adults regarding the effects of protein or amino acid administration on muscle protein synthesis. The other 13 studies did not indicate a difference between younger and older subjects [ 34]. Protein synthesis in the human body requires the intracellular availability of 20 different L-amino acids. Eleven of these so called “proteinogenic” amino acids can be endogenously synthesized in the human body (alanine, arginine, asparagine, aspartic acid, cysteine, glutamine, glutamic acid, glycine, proline, serine, and tyrosine; referred to as dispensable [formerly: nonessential] amino acids). Nine amino acids (histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine; referred to as indispensable [formerly: essential] amino acids) require regular dietary intake. Except for lysine and threonine, metabolic needs for indispensable amino acids can also be covered through the intake of the corresponding keto acids, as they can be transaminated in the body to yield the respective amino acid [ 10]. The indispensability of histidine at present is only proven for infants [ 11]; whether this also applies to healthy adults needs still clarification [ 2, 12]. subject performed 3 of these) – upright row, machine military press, dumbbell overhead presses, lateral dumbbell raises, shoulder shrugsA protein dose of 20–40g of protein (10–12g of EAAs, 1–3g of leucine) stimulates MPS, which can help to promote a positive nitrogen balance. There is novel evidence that suggests higher protein intakes (>3.0 g/kg/d) may have positive effects on body composition in resistance-trained individuals (i.e., promote loss of fat mass).

A higher protein intake compared with a lower protein intake in older adults (1.2 vs. ≥0.8 g/kg body weight/day, age of the subjects: 65-72 years [ 47]; 1.6 vs. 0.8 g/kg body weight/day, age of the subjects: 75 ± 3 years [ 48]; 1.3 vs. 0.9 g/kg body weight/day, age of the subjects: 67-84 years [ 49]; 1.2 vs. 0.8 g/kg body weight/day, age of the subjects: 70-79 years [ 50]) was also associated with greater fat-free mass or muscle mass, respectively, and partially with a lower loss [ 50] or even an increase [ 47, 48] of fat-free mass, body cell mass or muscle mass, respectively, over a period of several years. Data from the NuAge study showed a significant difference in men in fat-free body mass between the quartiles of protein intake at baseline (quartile 1: 0.86 g/kg body weight/day, quartile 4: 1.29 g/kg body weight/day, age of the subjects: 67-84 years) but no effect of protein intake on the loss of fat-free mass over 2 years. A cross-sectional study did not show any difference in muscle mass in subjects with higher protein intake compared with subjects with lower protein intake (≥1.2 vs. 0.8-1.19 g/kg body weight/day, age of the subjects: 50-75 years) [ 46]. It is well known that exercise improves net muscle protein balance and in the absence of protein feeding, this balance becomes more negative. When combined with protein feeding, net muscle protein balance after exercise becomes positive [ 161]. Norton and Layman [ 150] proposed that consumption of leucine, could turn a negative protein balance to a positive balance following an intense exercise bout by prolonging the MPS response to feeding. In support, the ingestion of a protein or essential amino acid complex that contains sufficient amounts of leucine has been shown to shift protein balance to a net positive state after intense exercise training [ 46, 150]. Even though leucine has been demonstrated to independently stimulate protein synthesis, it is important to recognize that supplementation should not be with just leucine alone. For instance, Wilson et al. [ 139] demonstrated in an animal model that leucine consumption resulted in a lower duration of protein synthesis compared to a whole meal. In summary, athletes should focus on consuming adequate leucine content in each of their meals through selection of high-quality protein sources [ 139]. Key pointsAlternative explanations for the decrease in fat mass in the high protein group include possible changes in resting and sleep energy expenditure. A recent study examined 25 participants who ate approximately 40% excess energy for 56days from 5%, 15%, or 25% protein diets. If the extra calories consumed were from protein, both sleep and resting 24-h energy expenditure increased in relation to protein intake. However, this investigation found no relationship between changes in fat mass and changes in energy expenditure [ 14]. It should be noted that there was not an exercise component to that study. I bought this as an alternative to whey in hopes of it providing a little more satiety while treating my muscles to a longer-lasting protein hit, and it has not disappointed. Mixing whey with water can feel like drinking watery calories, where as total protein feels way more substantial, creamy and satisfying. I was concerned looking at the protein blend that it might be difficult to mix - having bought caesin and egg white powder previously. Caesin bubbles like no tomorrow and feels like the power is suspended in the water/cottage cheese-y, and egg white powder seems almost waterproof, forming powder capsule lumps. Very impressed at how mixable total protein is, strawberry cream transforms into a dreamy creamy almost nesquik like drink. Another study examined 12 pairs of identical twins that overfed (~840 kcals extra daily) over 100days [ 15]. The average gain in fat mass and FFM were 5.4kg and 2.7kg. In comparison, our study showed an average loss of fat mass (0.3kg normal group, 1.6kg high protein group) and gain in FFM (1.5kg for both the normal and high protein group). The authors of the identical twin overfeeding study noted that no single variable was a great predictor of body composition changes [ 15]. The identical twin overfeeding study did not have an exercise component and did not use trained subjects. Thus, its relevance is questionable in athletic populations that purposefully engage in overfeeding.

At this point, whether any particular time of protein ingestion confers any unique advantage over other time points throughout a 24-h day to improve strength and hypertrophy has yet to be adequately investigated. To date, although a substantial amount of literature discusses this concept [ 60, 80], a limited number of training studies have assessed whether immediate pre- and post-exercise protein consumption provides unique advantages compared to other time points [ 72, 73, 81]. Each study differed in population, training program, environment and nutrition utilized, with each reporting a different result. What is becoming clear is that the subject population, nutrition habits, dosing protocols on both training and non-training days, energy and macronutrient intake, as well as the exercise bout or training program itself should be carefully considered alongside the results. In particular, the daily amount of protein intake seems to operate as a key consideration because the benefits of protein timing in relation to the peri-workout period seem to be lessened for people who are already ingesting appropriate amounts of protein (e.g. ≥1.6g/kg/day). This observation can be seen when comparing the initial results of Cribb [ 72], Hoffman [ 74] and most recently with Schoenfeld [ 82]; however, one must also consider that the participants in the Hoffman study may have been hypocaloric as they reported consuming approximately 30kcal/kg in all groups across the entire study. A literature review by Aragon and Schoenfeld [ 83] determined that while compelling evidence exists showing muscle is sensitized to protein ingestion following training, the increased sensitivity to protein ingestion might be greatest in the first five to six hours following exercise. Thus, the importance of timing may be largely dependent on when a pre-workout meal was consumed, the size and composition of that meal and the total daily protein in the diet. In this respect, a pre-exercise meal will provide amino acids during and after exercise and therefore it stands to reason there is less need for immediate post-exercise protein ingestion if a pre-exercise meal is consumed less than five hours before the anticipated completion of a workout. A meta-analysis by Schoenfeld et al. [ 84] found that consuming protein within one-hour post resistance exercise had a small but significant effect on increasing muscle hypertrophy compared to delaying consumption by at least two hours. However, sub-analysis of these results revealed the effect all but disappeared after controlling for the total intake of protein, indicating that favorable effects were due to unequal protein intake between the experimental and control groups ( ∼1.7 g/kg versus 1.3 g/kg, respectively) as opposed to temporal aspects of feeding. The authors concluded that total protein intake was the strongest predictor of muscular hypertrophy and that protein timing likely influences hypertrophy to a lesser degree. However, the conclusions from this meta-analysis may be questioned because the majority of the studies analyzed were not protein timing studies but rather protein supplementation studies. In that respect, the meta-analysis provides evidence that protein supplementation (i.e., greater total daily protein intake) may indeed confer an anabolic effect. While a strong rationale remains to support the concept that the hours immediately before or after resistance exercise represents an opportune time to deliver key nutrients that will drive the accretion of fat-free mass and possibly other favorable adaptations, the majority of available literature suggests that other factors may indeed be operating to a similar degree that ultimately impact the observed adaptations. In this respect, a key variable that must be accounted for is the absolute need for energy and protein required to appropriately set the body up to accumulate fat-free mass. Certainly, one should not discount the role of protein’s thermic effect (i.e., TEF or thermic effect of feeding). Protein has a TEF of approximately 19–23% in both obese and lean individuals whereas carbohydrate is approximately 12–14% [ 19]. In fact, a high proteinmeal (45% total kcal) elicits a 30% greater TEF than an isocaloric low proteinmeal (15% total kcal) in active females [ 20]. It should be noted that the TEF of fat is substantially less in the obese than in lean subjects [ 19]. The subjects in our study did not alter fat intake; thus, that could not be an explanation for changes in body composition. One could speculate that subjects in the high protein diet group experienced a combination of enhanced TEF, AEE, NEAT and SEE; this might explain in part the decrease in fat mass. Furthermore, the high protein group was more compliant with the exercise training regimen. The International Society of Sports Nutrition (ISSN) provides an objective and critical review related to the intake of protein for healthy, exercising individuals. Based on the current available literature, the position of the Society is as follows: Results from many single investigations indicate that in both men and women protein supplementation exerts a small to modest impact on strength development.

The aims of this review were to evaluate the effects of dietary protein on body composition in energy-restricted resistance-trained athletes and to provide protein recommendations for these athletes.
