The variables investigated were time of practice (years), average duration of training (minutes), training frequency weekly (days), training volume (km / week), sports competitions (number of events), distance km), performance in the tests (up to 5th place), already made use of dietary supplements, motivational factors for the use of supplements, use of pre and post workout supplements, runners' opinion regarding the use of supplements improve performance in training and water tests and consumption during training and testing. The variables were obtained through a questionnaire composed of 20 closed questions. Data were analyzed using descriptive statistics.
