In today's era, sports tourism is known as one of the popular tourist destinations. The combination of two important elements of sports tourism, i.e. sports career and tourism experience, leads to increasing people's desire to travel and take a break from everyday life. In fact, this type of tourism attracts people to the environment where sports activities are performed, and at the same time, it also improves their mental image. Based on research and scientific studies, the mental image of attracting sports tourism destinations is investigated in two different aspects. Placed. On the one hand, the mental image can be encouraging and inspiring to do sports activities in a new environment. In other words, the mental image attracts a person to a specific sports destination and encourages him to travel to that area and participate in his desired sports activities. On the other hand, mental image can act as a reinforcing factor to continue sports activities over time. For example, if a person has a positive experience of a certain sports destination, a positive mental image of that place and sports activity is formed in his mind and may encourage him to return to the same sports destination in the future. Therefore, the mental image of tourists plays an essential role in the realization of sports tourism destinations. Developing and strengthening the mental image of sports attractions can not only increase tourists' inclination towards this type of tourism, but may also create a continuous connection between the tourist and the sports destination. This research was conducted in order to investigate the effect of attractiveness of sports tourism destinations on the mental image of tourists with the mediating role of perceived usefulness. The present research is classified as a descriptive and analytical-documentary type of research. By carefully examining scientific sources and reliable domestic and foreign magazines, it was tried to clarify the concepts of the attractiveness of sports tourism destinations, the mental image of tourists and their perceived usefulness, and their impact has been investigated. The results indicate that the attractiveness of sports tourism destinations has a positive and significant effect on the mental image of tourists. Also, perceived usefulness as a mediator can affect the attractiveness of sports tourism destinations on the mental image of tourists.
