Abstract

To investigate the effects of protein hydrolysates on Physical performance and immunity in male players aged 18-21 years. Blood samples were drawn from 2 groups of athletes (10 subjects each). The first group ingested protein hydrolysates 0.4 g/k for 15 days, the second one ingested placebo for 15 days. All participants were subjected to Copper test as a field test for VO2 max determination, according to standardized protocol of Burke (1996). The other parameters determined were, Leucocytes, Neutrophils, CD 45+ (lymphocytes) D14+ (monocytes), together with free testosterone, cortisol and insulin, using coulter counter, flow cytometer and Elisa techniques. Results: Protein hydrolysates revealed an increased cellular parameters WBCS, CD45+, CD14+), together with elevated free testosterone and insulin concentrations with lower cortisol. VO2 max increased following protein hydrolysates administration. In response to protein hydrolysates ingestions some immunological variables are enhanced together with higher anabolic hormonesand lower cortisol concentration, this might stimulate physical performance.
