Proteine
Different proteins are built up from different sequences of the 20 amino acids. Amino acids (AAs) may be found in supplements either singly, as two linked AAs (dipeptides) or as three linked AAs (tripeptides). More than three interlinked AAs are known as (oligo)peptides; if they also have a spatial structure (and hence a special functionality), they are called proteins.
The protein requirement for sportspeople is higher, especially during the strength development phase.
Reasons for increased protein requirement
| • | More protein is required in order to form new muscle (development training) | |
• |
| Increased requirement to maintain the larger muscle mass (attrition rate) |
• |
| Increased depletion of functional proteins and other nitrogen compounds |
• |
| Stimulating effect on protein synthesis (muscle synthesis) |
• |
| The pool of free amino acids in the body is used as an additional energy store. (Used to protect against the depletion of the body's protein) |
• |
| Proteins support regeneration and strengthen the immune defenses. |
Protein requirement in figures
An adequate supply of protein must be taken into account for long periods of sporting activity over several stages. Stress on the muscles during endurance trials should not be underestimated, and the body benefits from a regular intake of protein. Long-distance endurance athletes in particular often neglect the protein intake in their everyday diet at their peril. Many sportspeople are still insufficiently aware of the importance of proteins, and they focus instead on fluids and energy when it comes to nutrition during a competition. But if proteins are used in a targeted manner during the competition, they can already compensate for muscular exertion at an early stage and can play a supportive role during the regeneration that follows.
People with an average level of activity should consume approx. 0.8 g protein per kg of body weight per day.
During the training phase, and especially the strength development phase, the protein requirement may rise to as much as 2.0 g of protein per kg of body weight. For a sportsman weighing 60 kg, this is equal to 120 g of protein per day.
The protein requirement for endurance athletes during competitions that last several days is approx. 1.5 g protein per kg of body weight. For an athlete weighing 60 kg, the requirement is therefore approx. 90 g of protein.
Even this increased requirement can generally be met with a balanced diet. However, people who eat irregularly (e.g. in order to attain or maintain a low body mass or a low proportion of body fat, using a restricted range of foods), those who maintain a poorly composed vegetarian diet and those do not have much knowledge of nutrition can benefit from protein supplements. Proteins and amino supplements during training as well as competitions support regeneration and also strengthen the immune defenses.
Forms of protein supplements
Intact proteins
Intact proteins are the same as food proteins; they are known as polypeptides, in which large numbers of different amino acids are chained together. The digestive tract must split these proteins into free amino acids, dipeptides and tripeptides, so that it can absorb them. Most powders and meal substitute drinks contain various combinations of wheat, egg, dairy and soya proteins as well as casein.
The best argument in favor of intact proteins is that the human organism has adapted to digesting them over millions of years. The body therefore reacts functionally and efficiently when they are consumed. In sports nutrition, the intake of intact proteins is recommended as a basic supplement at breakfast, or spread throughout the day.
Protein hydrolisates
Protein hydrolisates are obtained from the enzymatic break-up of intact proteins into individual amino acids, dipeptides and tripeptides.
The advantage of protein hydrolisates is that they already come in "pre-digested" form. This enables the body to save work (energy and time) to split the peptides and it can absorb the amino acids more easily and quickly. This is why their use is generally recommended directly before, during or directly after training.
Free amino acids
Free amino acids are produced from the fermentation of proteins by bacteria.
The advantage of free amino acids is that they can be mixed as desired in the required proportions, and they also feature relatively rapid bio-availability (i.e. ability to be absorbed by the body).
Protein Supplements from Sponser
Basic products
 | Multi Protein 180Protein concentrates such as Multi Protein 180 are most suitable as basic products. They mainly contain intact proteins, so they have a longer resorption and utilization period. They supply the body with proteins in general. | |
 | Whey Protein 94Whey Protein 94 is rich in glutamine peptide (for faster regeneration, increased muscle development and glycogen storage) and immunoglobulins. Immunoglobulins not only strengthen the immune defenses but also inhibit the depletion of proteins (or encourage their increase). | |
 | Whey Colostrum 185Whey Colostrum 185 also offers the combined benefits of a protein that is available both quickly and slowly. Colostrum is a term that denotes the first milk of mammals. This milk is especially rich in growth factors and substances for the immune defenses. This is why Whey Colostrum 185 is taken in particular after training (for immediate muscular regeneration, among other purposes) and as a supplement during the low-protein night phase. Because of its wide range of effects, Whey Colostrum is especially advisable as a source of protein during competitions and training camps that last several days (phases involving increased physical stress). |
Basic products with protein hydrolisates
 | Amino ForceThe di- and tripeptides from dairy protein hydrolisate contained in Amino Force are utilized faster and better by the body than intact proteins or free amino acids. The greatest increase in weight has been achieved with dairy protein hydrolisate (2x more than with intact proteins, 5x more with free amino acids).
| |
 | Glutamin PeptidGlutamin Peptid contains di- and tripeptides from wheat protein hydrolisate. Glutamine is the amino acid which occurs most frequently in the muscles. Glutamine supports recovery after exertion as well as muscle development and glycogen storage. | |
 | Amino 12500Amino 12500 contains 12.5 g of dairy protein hydrolisate, including 1.1 g of BCAA (Branched Chain Amino Acids: Valine, Leucine, and Isoleucine which can be utilized directly by the muscles), as well as the reminder of the amino acid spectrum plus vitamin B6 and pantothenic acid. |

 | BCAABCAAs play an important part in nutrition for powersports participiants and endurance athletes. Branched chain amino acids which can be absorbed directly by the muscles are used by the body as fuel when it is under stress, unlike all other amino acids. The body can also produce its own glutamine from BCAAs. | |
 | EACEAC is ideally taken before, during and after intensive strength training. Since EAC only contains essential amino acids, this supplement is ideal for endurance sports participants who are conscious of body fat because the depend on a low body weight. |
