      Kerasioti, E.; Stagos, D.; Priftis, A.; Aivazidis, S.; Tsatsakis, A. M.; Hayes, A. W.; Kouretas, D. (2014)
      In the present study, the in vitro scavenging activity of sheep whey protein against free radicals, as well as its reducing power were determined and compared with that of beef protein, soy protein and cow whey protein. ...
    • Comparison of the blood redox status between long-distance and short-distance runners 

      Kostaropoulos, I. A.; Nikolaidis, M. G.; Jamurtas, A. Z.; Ikonomou, G. V.; Makrygiannis, V.; Papadopoulos, G.; Kouretas, D. (2006)
      Exercise increases the production of reactive oxygen species, which may damage a number of cell constituents. Organisms have developed a sophisticated antioxidant system for protection against reactive oxygen species. Our ...
    • Increased oxidative stress indices in the blood of child swimmers 

      Gougoura, S.; Nikolaidis, M. G.; Kostaropoulos, I. A.; Jamurtas, A. Z.; Koukoulis, G.; Kouretas, D. (2007)
      The blood redox status of child athletes is compared with that of age-matched untrained individuals. In the present study, 17 swimmers (10.1 +/- 1.6 years) and 12 non-athletes (9.9 +/- 1.1 years) participated. Reduced ...
