Purpose: This study aims to investigate athletes' participation on online social network. The purpose was to explore how to properly use online social media with ethical considerations. Methods: The methods are based on current literature reviews domestically and internationally. Results: The study found out that online social network not only provides opportunities for athletes to develop potential social connection with friends, but also create a possible platform for discussion on current events. Athletes can use social media for the further communication while developing interpersonal relationships for better visibility. Conclusion: The online community brings a new mode of communication, and provides people with a platform for further interaction and exchange. In this study, we have proposed six precautions and six practical rules for athletes. In addition, we have also provided with four online examples. While athletes should take advantage of modern media exposure and seize the opportunity to express themselves during an interview, the best ways to respond to our social media are: always be well prepared, honesty, to learn from role models around, and to leave good impression. All of that should be conducted in an appropriate manner with ethical considerations as well.
