- the present invention relates to dietary supplements containing alpha-keto analogs of branched-chain amino acids in support of the
- Muscle building increased muscle performance and improvement of general well-being while relieving the metabolism to nitrogen detoxification by reduced nitrogen intake compared to the intake of the corresponding amino acids and an improved nitrogen metabolism in the body.
- Physical inactivity is a risk factor that can lead to decreased physical performance and thus reduced quality of life.
- a physical training is essential, with a
- the average requirement for protein is about 660 mg / kg body weight, which can be significantly increased by physical training.
- the need for protein can usually be met by a balanced diet, which is not easy to achieve.
- Physical training leads, caused by increased protein degradation and humiliated Protein synthesis, to a changed need for nutrients, continues to result in a changed metabolic situation, which is due for example to the influence of physical training on the hormone system and ultimately also lack knowledge about a suitable diet with increasing physical stress, especially in relation to the age, so that fast one
- BCAA branched chain amino acids
- Branched-chain amino acids alpha-keto acids also play an important role in amino acid metabolism, especially in skeletal muscle and in the liver.
- One-third of the muscle protein consists of the branched-chain amino acids, which can not be formed by the body, but must be taken with the food. In muscle, especially during physical exertion, proteins are constantly being built up and broken down
- the corresponding alpha-keto acid is formed by transfer of the amino group to a carrier.
- the obtained keto acid can then be further enzymatically oxidized for energy.
- the carrier is transported to the liver where it releases toxic ammonia, which must be converted to urea and excreted via the kidney.

- V ⁇ 2max the maximum oxygen uptake
- the load on a cycle ergometer is increased by means of a ramp protocol (for example beginning 0 watt, continuous increase of the power with 50)
- the heart rate can be determined synchronously by means of electrocardiography.
- Oxygen uptake is calculated from online minute ventilation and the difference in oxygen concentration between inspiratory and expiratory gases.
- IAAS Individual Anaerobic Aerobic Threshold
- the measurement of the bounce improvement can by means of a
- Bounce plate of the company Kistler, Winterthur, Switzerland be determined.
- the device's own protocols "Squat-Jump” and “Count-Movement Jump” are used. The bounce is measured based on the contact time on the measuring plate and the jump height and calculated in comparison with the body weight.
- the maximum force e.g. the leg muscles are stressed at a defined angle and the maximum force is measured.
- Metabolic parameters e.g. the concentrations of BCKA and AKG or urea or uric acid concentration in the blood can be determined by HPLC
- Measurements are measured. To determine the damage of muscle cells, e.g. During physical exercise, uric acid levels in the blood or urine or creatine kinase activity in the blood are determined. The increase in creatine kinase activity correlates with the extent of muscle damage and may be due to an enzymatic reaction
- kit no. 1087533 from Roche Diagnostics, Mannheim, Germany.
- the uric acid concentrations can be determined photometrically using the "Fluitest IIA®” kit from Biocon Diagnostics, Vöhl / Marienhagen, Germany.
- the effects of the claimed dietary supplement on protein metabolism can be demonstrated by measurements of urea concentrations in the blood or urine.
- the urea concentrations can be determined by photometric end point determination at a wavelength of 334 nm using the urea S test combination (reagent kit No. 777510 from Boehringer Mannheim, Germany).
- a supportive effect of the claimed dietary supplement with regard to muscle growth can be made by determining the expression of the myogenic factors Myo D and myogenin by RT-PCR.
- the subjects are given tissue samples before and after the training phase from the muscle by biopsy, using a biopsy needle (e.g., a 13-gauge biopsy needle of the
- the muscular adaptation can also be checked by the analysis of the myosin heavy chain (MHC) isoforms or by the determination of the stress protein Hsp70 (inducible form) (analytical method, for example according to Liu et al., Eur. J. Appl. Physiol. 91: 330-335, 2004, Liu et al., Int J. Sports Med. 21: 351-355, 200, Liu et al., J. Appl.
- MHC myosin heavy chain
- BCKAs branched-chain alpha-keto acids
- Training 30 minutes of endurance training (running) per day 3x3 minutes of high-speed running per day
- Keto acids in the composition described below or Mix 2 (placebo) in which a subject always took the same mix over the entire duration.
- keto acid mixtures can be stirred into commercially available sweet or salty products such as yoghurts, whey drinks, fruit compote and dessert soups.
- the training was performed according to the above form and controlled by the subjects themselves.
- the training was carefully documented by the test persons in the training protocol and regularly checked in random samples. Therefore, we assume that the completed training questionnaire is essentially plausible.
- Performance in particular the parameter "sustained exercise time” as an expression of exercise tolerance, on general physical performance as well as on muscle function. According to our study design, the training was to be done with 5 units per week, with each training session providing 30 minutes of endurance training
- Figure 1 shows the total exercise time per week. The total training time in the 1st week did not differ between the groups.
- the urea concentration in the plasma had a similar level before training in both groups. At the end of training, the urea concentration in both groups was higher than before, but to varying degrees depending on the dietary supplement. The increased urea concentrations after the training indicated an increased urea synthesis, which resulting from a reduced due to physical training protein degradation.
- Plasma urea concentration at the end of exercise in the BCKA group was significantly higher than that in the placebo group. After one week of regeneration, no further increase was found in the BCKA group, while there was a marked increase in the placebo group.
- urea synthesis is based on the protein-derived ammonia
- increased urea synthesis may be explained by the fact that the ammonia produced in the working musculature, resulting from protein degradation by catabolism, is more rapidly transported to the liver; or possibly KAS has favored urea synthesis in the liver.
