PROFORCE--a new, high-biologic-value protein product for athletes

The protein product PROFORCE has been developed from a base of egg, milk and cereal using linear optimization. Its balanced composition has been specially designed to meet the physiological needs of athletes practicing endurance-demanding sports. A medicobiologic evaluation using a routine technique was performed using three concentration levels of protein feeding. This enhanced the range of the investigated parameters. The following results were obtained: Protein Efficiency Ratio (PER) = 2.64 +/- 0.22 (p < 0.001); Net Protein Ratio (NPR) = 3.27 +/- 0.22 (p < 0.001). Comparison with the control group shows that the protein product is of high quality. Albumin, cholesterol, triglycerides and total protein were determined for the three protein-feeding concentrations. The most favorable influence on the protein parameters and cholesterol levels were observed when feeding experimental rats on the nine-percent protein concentration. Amino acid content of the product was compared to a number of proteins of proven high quality. The comparison suggests that the product is suitable for athletes practicing endurance-demanding sports. The conclusion is that PROFORCE has a wide range of applications which would include use by athletes practicing aerobic sports.
