RESUMEN
Food supplements contain a variety of combinations of vitamins, minerals, plant extracts, and other substances. Any physical effort requires energy from balanced and healthy nutrition. This research aimed to identify the categories of dietary supplements used by active and very active participants who attend the sports and leisure centers from Targu Mures city. The survey was developed in paper and online forms using the Internet and supported multimedia and self-administration. The sample consists of 517 subjects chosen randomly from the research population and divided into the active and highly active PAI subgroups based on age, education, and gender. IBM SPSS Statistics Version 20.0 was used to process the collected data. All data were analysed descriptively. Differences between independent groups were assessed using an Independent sample t-test and a Chi-square test. Statistical significance was accepted when p < 0.05. Additionally, a Pearson correlation was done. The most representative age category was between 18 and 22 years old (42.7%), the ones using dietary supplements most frequently. There were significant differences by group of age regarding the consumption of food supplements (p < 0.05) and also by gender (p < 0.05).
