The purpose of this study was to analyze the effects of perceived coach leadership behaviors on high school soft tennis players' satisfaction. Team players from each high school team who participated in the 31st National CKS Cup of Soft Tennis Competition were the study targets and a total of 80 questionnaires were distributed. There were 64 effective questionnaires with a retrieval rate of 80%. The results are as follows: (1) Among the 5 phases that constituted perceived coach leadership behaviors for high school soft tennis players, "training and instructing behavior" received the highest score. This is followed by "caring behavior", "democratic behavior", and "encouraging behavior", whereas "tyrannical behavior" received the lowest score. (2) Among the 4 phases that constituted satisfaction of high school soft tennis players, "overall instructing behavior of coach" received the highest score for level of satisfaction. This is followed by "overall performance of the team" and "performance of team results", where "performance of personal sport achievement" received the lowest score for level of satisfaction. (3) Regarding analysis on the "different perceived coach leadership behaviors for high school soft tennis players from diverse backgrounds" variable, the results indicated that players of different genders reached noticeable differences for "encouragement behavior", "tyrannical behavior" and "democratic behavior" within the perceived coach leadership behaviors. Players under highest sports achievement for individual diversity reached noticeable differences for "caring behavior" within perceived coach leadership behaviors. As for players from different training hours a week, there were no obvious differences within the perceived coach leadership behaviors. (4) Among analytical results on differentiation of "satisfaction from high school soft tennis players of diverse backgrounds" variable, players of different genders, and the highest sports achievement reached obvious differences under "performance of personal sports achievement" in the player's satisfaction measurement. As for players from different training hours a week, there were no obvious differences within the player's satisfaction measurement. (5) "Caring behavior" and "encouraging behavior" within perceived coach leadership behaviors showed a positive value; these are capable of effectively forecasting player's overall satisfaction.
