New Protein Bar for Physically Active People

The clinical study will be performed on 10 elite handball players from Slovenia handball club. It will be designed as a crossover study. Half of the participants will consume the new bar for five days and the other half will consume the control bar. After the five-day washout period, the groups will consume the bar which was not consumed in the first period. At baseline, at the end of every intervention and washout period, the blood samples will be withdrawn, and the body composition will be analyzed. The analyzed biochemical parameters will be basic serum parameters, such as fasting glucose, total cholesterol, LDL, HDL, triglycerides, aspartate aminotransferase (AST), alanine aminotransferase (ALT), C-reactive protein (CRP), and parameters related to the muscle regeneration and inflammation, such as creatine kinase, lactate dehydrogenase, insulin-like growth factor (IGF), tumor necrosis factor alpha (TNF-alpha), interleukin 6 (IL-6), monocyte chemoattractant protein 1 (MCP-1). In the second part of the study, the acute effect of consuming each bar after training will be tested. Each participant will consume both bars on separate days. The mentioned parameters will be assessed after training and immediately and 3h after bar consumption.
