It is common knowledge that the communication skills are the appanage of social intelligence. This paper seeks to identify the interpersonal strengths and weaknesses in young adults practicing the competitive sport. For that, we have used the communication skills inventory which enables the identification of four types of communication skills: self-revealing, building the trust, communicating the feelings, appreciating the diversity. Results emphasized the fact that the athletes included in the research have obtained high scores in 3 from 4 types of communication skills. This shows that they are very well acquainted with these communication areas, haved the ability to understand others for what they are (appreciating the diversity -32.41), haved the ability to trust in others as well as... to gain the trust of others (building the trust – 30.73) and having the ability to share their feelings with others (communicating the feelings – 30.66). Through sport, athletes are appreciating the diversity which is a very important and inevitable skill in the relations with other co-athletes. This indicates that they are efficiently interacting with other individuals, regardless of the culture, social status and ethnicity.
