Values were obtained for height (1.84 +/- 0.08 m); weight (81.4 +/- 9.9 kg): and fat percentage (16 +/- 4.5%). 100% sample answered to have consumed some type of SND. and significant differences were found (pd"0.005, O = 3.155) between national subjects (n =5) (7.6 SND per subject) and international subjects (n =15) (17.87 SND per subject). The most consumed SND were: iron (85%), caffeine (85%). beta Amine (85%), energy bars (85%), vitamin complexes (80%) and isotonic drinks (80%). There is a high consumption of SND by the sample, mainly international. 100% respects the legality of the supplements consumed and the main purpose of its use was to improve its athletic performance.
