Study the gender effect in plasmatic concentration of 25 amino acids in high-level athletes after a long intermittent exercise. At the beginning and at the end of exercise amino acids plasmatic concentrations are measured by chromatography. Result and conclusion There are significant differences between men and women in both situations at rest (for two amino acids: ornithine and glutamine) and after intermittent exercise. Taurine and glutamic acid increase and serine decreases in women, while alpha amino-butyric acid decreases in men; differences probably linked to the hormonal status.
