Abstract
Objective: Ergogenic aids are substances, practices, or techniques that athletes use to support or improve their physical performance before, during, and after exercise. Although the ergogenic substances examined in this research can be found in the market in various formulations and contents, the most preferred type by athletes in recent years is natural-source ergogenic aids, some of which are also used as food and "considered to be more harmless". Naturally sourced ergogenic aids support the performance of the athlete if the right plant, the right drug, the right product, the right time, the right dose and the appropriate formulation are used. Otherwise, in addition to benefiting from this support used by the athlete, results that may adversely affect his health may ocur. Although sportive performance is a priority for the athlete, it is also reported in the literature that the most important thing is the health of the athlete.
Result and Discussion: In this review, it is aimed to determine the natural origin ergogenic aids preferred by the athletes in recent years with a detailed literature review in PubMed, Science Direct, Google Scholar, BioMed Central, TUBITAK Ulakbim databases, and to examine the positive and negative aspects of the most frequently used ones in the light of current data.
