The recipe for recovery
According to Euromonitor figures worldwide sales of sports related protein products grew from £2.5bn in 2007 to £4.9bn in 2012 and are likely to reach £7.8bn in 2017. A key driving factor attributed to this growth is an increasing number of mainstream consumers actively seeking to manage their weight and develop muscle mass through the combination of exercise and nutrition.
Whether the goal is weight management, muscle development or improved overall performance, protein plays a crucial role in recovery. Recovery refers to the period of time required for the body to make the necessary repairs from exercise related stress (muscle hypertrophy) in order to return to optimum performance.
By consuming products after exercise that contain easy to absorb protein ingredients, consumers can speed up recovery enabling them to return to an exercise regime and peak performance more quickly.
Prodiet Fluid from Ingredia Nutritional is a high quality milk protein isolate (MPI). Its technology allows to reach a 14% protein content while maintaining a fluidity similar to that of milk. Prodiet Fluid reduces liquid viscosity by up to 88% compared to a similar MPI making it ideal for ready-to-drink sports drinks for performance, muscle building or recovery.
Providing a natural milky taste with no off-flavour Prodiet Fluid offers stability to high temperatures so can undergo UHT treatment and also features a clean label. The milk protein is naturally rich in native micellar caseins, featuring a chemical index superior to 120 and a high content of bioavailable native micellar calcium.
In November 2012 Ingredia Nutritional won Physical Performance Innovation of the Year for Prodiet Fluid at Health Ingredients Europe’s NuW Excellence Awards.
Utilising the technological properties of Prodiet Fluid, Ingredia Nutritional have developed a number of concepts for protein drinks. Muscle Repair is a high protein drink designed to be consumed before going to bed to wake up alert and rested, helping to repair muscle tissue while sleeping with caseins and slow release proteins. Recover is another high protein drink concept that targets sports people. It is designed to be consumed right after sport sessions. This product combines milk protein hydrolysates and caseins for fast and longer action. Both are rich in BCAA for a more efficient muscle recovery.
Volactive ProCrisp by Volac is an ingredient developed for when taste and texture is as important as function in sports, health and satiety products. ProCrisp is a co-extruded product manufactured from a combination of whey protein isolate and rice flour. It delivers a light and crispy neutral tasting whey protein sensation that fits the main product trends such as breakfast cereals and snack bars.
Volac’s consumer research and collaboration with customers has indicated that there is strong consumer demand for products that deliver proven health benefits, while at the same time great taste, texture and mouthfeel. Volactive ProCrisp allows for uncomplicated flavour profiles in finished products which meet the demands for high protein snacks.
With the current sports nutrition market crossing over into all consumer groups, from those seeking an active lifestyle to athletes, and now even including the ageing population, ProCrisp provides a solution for this fast expanding market. Volactive ProCrisp can be used across a range of functional protein products to help restore, maintain and build muscle after physical activity.
Hydro 365 developed by Arla Foods Ingredients is a whey protein hydrolysate, designed to speed up recovery after training. Lacprodan Hydro 365 is an easily digested, rapidly absorbed protein source. Taken within two hours of training, a 20-50g dose may reduce muscle recovery time from days to just a few hours and, at the same time, enhance muscle building.
Whey protein is known to be an effective type of protein for aiding recovery due to its rich amino acid content. But whey protein hydrolysates like Hydro 365 are scientifically proven to offer superior benefits because they are digested and absorbed more quickly, optimising the body’s muscle-building and repair response following exercise. In one study, which monitored athletes taking whey protein hydrolysates after exercise, the results indicated that they could recover their full peak power and eliminate muscle soreness after just six hours, compared with several days in the case of standard whey protein.
The easy absorption properties of Lacprodan Hydro 365 results from the hydrolysation process, where proteins are broken down into amino acids and small peptides. In this pre-digested form, proteins are documented to have faster access to the blood stream than intact proteins. When consumed with easily absorbed carbohydrates, the whey protein hydrolysate induces a higher concentration of insulin in the blood, optimising the body’s ability to restore energy stores in tired muscles. The high content of branched chain amino acids and leucine further initiates the synthesis of new proteins. As the rate at which the body consumes these amino acids is 25% higher during exercise, prompt dietary supplementation benefits muscle growth. The company recently launched a hydro365.info website to communicate the ingredient’s possibilities.
Pro Go by Solanic is a range of pure potato protein isolates with a balanced amino acid profile and high in essential amino acids. It is also rich in Branched Chain Amino Acids which support muscle synthesis and counter fatigue.
Recent studies comparing the health effects of eastern and western diets found that the plant based diets of Asia, low in animal protein and low in fat helps to reduce the risk from a number of diseases. Growing awareness as to the chronic health effects of food allergies is fuelling the market for free-from foods. Consumers of protein products who suffer from allergies may actually be exacerbating these conditions. This would also have a negative effect on the digestion of the protein thereby limiting any recovery benefits.
Potato protein has low allergen content avoiding conditions such as lactose intolerance which in can hinder the absorption of dairy based protein. This is felt with Pro Go by reports of gastro-intestinal comfort. A protein of this type might therefore be beneficial after, before and during exercise unlike dairy protein which can clot in the presence of acid. Pro Go also contains cysteine to support strong immune defences.
Nutralys from Roquette is a pea protein isolate extracted from the the yellow pea (pisum sativum), a staple in the Indian diet shown to contribute towards growth in muscle mass and maintenance.
Due to its extraction process Nutralys is highly purified resulting in 85% protein content. The estimated PDCAAS of pea protein was given as 93% for adults. This is comparable to casein, eggs, and soy and much higher than that of common vegetable-based protein sources. Nutralys also has a higher arginie content than other plant and animal proteins at 8.7% per gram of protein. Arginine is an interesting amino acid for athletes as it is involved in creatine synthesis, it is a precursor of nitric oxide synthesis and exogenous arginine can promote growth hormone release.
Nutralys pea protein is also a good source of branched-chain amino acids and glutamine, both of which are also of particular interest for sports performance. Recent evidence shows that the branched-chain amino acids promote muscle growth and repair, particularly after resistance training. It has also been demonstrated that leucine, when consumed with carbohydrates, stimulates muscle protein synthesis and optimises whole body protein balance when compared to the intake of carbs only. At the same time, L-glutamine is the most abundant amino acid in blood and muscles and is an essential amino acid in high intensity training.
Pea protein is easily digested and not on the EU list of major allergens (Codex and EU) allowing for it’s use in free-from products as a total or partial replacement of milk or soya proteins.
