Introduction Nutrition is traditionally perceived as a crucial component of physical fitness and performance. In the last few decades, theincreasing understanding of human nutrition and exercise physiology has showed that a wise management of nutrient intake couldpositively affect fitness improvements and sport performance. The aim of this study was to examine the use of dietary supplements and diet behavior amongst regular fitness centers users in Italy. Methods A specific questionnaire was generated for the experimentation. Thedata were collected using the face-to-face interview method. Only strength and conditioning classes participants were included in theselection criteria. Training information have been collected from 800 regular fitness center attendees; 207 of them were selected for thestudy. Analysis: Significance differences were assessed by one-way ANOVA, Kruskall-Wallis, chi-square test or exact test of Fisher whenappropriate. Results Dietary supplements proved to be used by 30.1% of the respondents. Use of supplements was lasting on average2.6±3.3 years without any significant difference by gender. Whey protein shakes (50.0%) mixed with creatine and amino-acids (48.3%)was the most frequent choice among users. Supplement non-users consumed more snacks and bakery than users per week (P < 0.001).Conclusions A considerable number of regular strength training subjects consume protein supplements mixed with other supplementsand high-protein foods, in particular meat. We emphasize the importance of the dissemination of scientifically based information aboutsupplementation in the fitness centers and the promotion of updated education programs for fitness instructors.
