The purpose of this study was to analyze the kinematical variables involved in two types of service motion in tennis pinpoint and platform stance, to find the fastest serving method. Seven skilled high school tennis players participated, and the kinematics were recorded by the Vicon motion analysis system. For the gathering and analysis of the data workstation, bodybuilder and polygon were used. During the back swing for the pinpoint stance, as the back leg moves forward the COM and the racquet moves more, thus taking 0.04 seconds longer than the platform stance. The body of the subject takes a bow-shape as the subject's foot moves back and their hip moves forward. This movement enables the subject to create more power during the backswing to impact. It also increases the spread of the COM racquet and the serve speed is increase. As there is no forward movement of the foot during the backswing of the platform stance, the COM and the racquet move less and thus the time required is shorter than that for the pinpoint stance by 0.04seconds. Similarly, the time spent creating the power for the serve is shortened, the COM racquet is narrower and the speed is lessened. However, the advantage of this serve is that it increases the stability.

Canonical correlation biplot is 2-dimensional plot for investigating the relationship between two sets of variables and the relationship between observations and variables in canonical correlation analysis graphically. Recently, Choi and Choi (2008) suggested a method for investigating the relationship between skill and competition score factors of KLPGA players using canonical correlation biplot and cluster analysis. analysis. Procrustes analysis is very useful tool for comparing shape between configurations. Therefore, in this study, we will provide a method for investigating the relationship between player characteristic factors and competitive factors of tennis grand slams competition using Canonical correlation biplot and Procrustes analysis.

The purpose of this study is to investigate how the impact on the basic psychological needs and emotional and motor sports commitment to participate in 12 weeks of Physically Disabled wheelchair tennis class. Results: First, the basic psychological needs is a difference between groups was found in the autonomy and the relationship of the sub-factors autonomy, competence, was the difference in time measured between the castle. Second, the movement was born immersed in the measuring point to see a difference in cognitive involvement and engagement of sub-behavior factors, the mutual effects were measured at the time of the two groups and sub-factors. Third, the movement was born in sentiment appears to have overlooked the measurement point in the sub-group differences in factors such as positive emotions and negative emotions, collective and cross effects were measured at the time of the two sub-factors. Subsequent studies in qualitative research, as well as be able to induce a more active ongoing participation of the disabled being difficult to draw parallel with the subjective experience of people with disabilities, it is thought to be possible to develop a variety of programs.

The purpose of this study was to analyze the kinetics variables of GRF by dtance type during forehand stroke. Eight high school tennis players, who have never been injured for last six months, in Busan were chosen for the study. They performed horizontal swing and vertical swing that it was done each five consecutive trial in the condition of square, semi-open and open stance. It was filmed by 6 video camera and used with 3-dimensional motion analyzer system and GRF system. The following kinetic variables were analyzed in relation to left leg and right leg GRF. The conclusion were as follow: 1. In square and semi-open stances, the horizontal ground reaction force was decreased at impact in left leg regardless of swing type, whereas open stance was increased at impact to the tiptoe in both legs. 2. In square and semi-open stances, the vertical ground reaction force was increased at impact in left leg regardless of swing types, whereas open stance was decreased at impact to vertical direction in both legs.

This study which was conducted on male tennis player on one hand(OH) & two hand(TH) backhand stroke and how both motion differed on low extremity movement with each feature analyzed in detail, the result as follow. The motion of TH based on resultant velocity, appeared to be a higher than OH, which was important variable in determining the ball speed. Contrary to TH where the player minimized the motion in the lower body and finalized a stroke through the turn of the trunk as if sticking the ball closed to the body, OH was carried out such that the player appeared to chase the ball. Whereas in OH, the knee joint extension moment was not found to be larger than TH, the opposite result came out for abduction moment and internal rotation moment. In the case of hip joint, consisted of extension, abduction and internal rotation moment, the outcome emerged to be greater for TH with conspicuous difference in abduction moment. Flection moment for TH overwhelmed in TH though both adduction and external rotation moment brought about similar outcome for both strokes.

The purpose of this study was to develop and evaluate the program for convericient reconfiguration in an attempt to change maladjustmental way of thinking among female junior tennis players. For verification of the program, a qualitative analysis and quantitative analysis were carried out. Through the REBT program for convericient reconfiguration, maladjustmental way of thinking among junior tennis players was drawed and interviews with them were subsequently performed. As a result, REBT counseling technique was applied to understand personal psychological problems and to transform maladjustmental and unreasonable way of thinking into rational belief, confirming positivity toward their situation. After all, their athletic performance as well as holistic development was found to be improved. In quantitative analysis, maladaptive thinking scale sports psychology questionnaire and survey for Korean sports performance strategy were both increased post treatment, suggesting that their psychological status became positive as a result of application of psychological prevention. The results of this study showed that athletic performance would be enhanced and growth and development in personality and self-realization would be expected if various psychological problems in adolescent players were progressed in detailed.
