The purpose of this study was to provide kinematic information with volleyball coaches and instructors on differences about floater serve motion between unskilled player and the skilled player. For this study, kinematic differences of floater serve was examined using comparing analysis between elite middle school volleyball player's floater serve motion and unskilled college volley club member's motion. The results of this study indicated that center of gravity displacement was not changed between skilled and unskilled players. However, unskilled player showed faster velocity of center of gravity than skilled player. In E1(Toss) phase, shoulder angle of unskilled player showed lower than shoulder angle of skilled player, and elbow angle of skilled player showed lower than elbow angle of unskilled player, and wrist angle was not changed both players. In E2(impact) phase, angular velocity of shoulder and elbow showed faster unskilled player than skilled player, and angular velocity of wrist showed faster skilled player than unskilled player.

Purpose: In this study, based on the self-determination theory we examined mediating effects of psychological need on the relationship between caring and exercise adherence. Methods: The proposed model was verified by hierarchical multiple regression analysis of 297 participants in the fitness center, and the statistical significance of the indirect effect was tested through bootstrapping. Results: As a result of examining the indirect effect on the proposed model, there were statistically significant mediating effects, caring → autonomy → tendency, caring → autonomy → strengthening, careering → competence, possibility and caring → relation → strengthening. As a result, caring was shown to enhance the exercise adherence through basic psychological need. Conclusion: Through this study, it was found that the process of psychological change of caring on the exercise adherence is mediated through basic psychological needs. This result implies that strategies for improving basic psychological needs should be centered on developing effective caring instruction for coach.
