This is a study on University/College level representative rugby teams. The aim is to gain understanding, by way of questionnaire, of factors correlating team coach leadership behavior with team solidarity on the part of the players. Analysis of the results showed that most of the factors concerning coach leadership behavior have not reached a level of significance, with the only exception of the factors "training and commendation behavior" for different teams, and "democratic behavior" for different leagues. The factor of player’s sense of solidarity for the team does reach significant level for different teams, and the factor "inter-member relationship" also reaches significant level for different leagues with league B players measured higher than league A players. Thus coach leadership behavior exhibits a positive correlation with the sense of solidarity in team members, with the highest values of correlation at "teaching and sympathetic behavior" and "team cooperation tacit understanding". The study lends itself to recommending to rugby coaches that appropriate leadership behavior should be selected depending on a player's particular attributes and the milieu of the training session. This would result in building a sense of belonging in the team members, maintain team harmony, and improving the sense of solidarity. We recommend also that follow-up studies can be done on more concrete causalities, and extend the results on high school and junior high school rugby.
