The relationship among Anxiety, Self-Efficacy, Coping with Stress, and Rehabilitation Adherence in Injured Athletes who participate in Sport Injury Rehabilitation program The purpose of this study was to investigate the relationship among anxiety, self-efficacy, coping with stress, and rehabilitation adherence in injured athletes who participated in sport injury rehabilitation program, to understand psychological distress of the athletes about the rehabilitation program, and to suggest the importance and necessity about a psychological training program during rehabilitation program. 250 injured athletes who participated in the rehabilitation program at N, K, S, B, D hospital in Seoul or Gyounggi-Do were selected as the subjects for this study, but 25 injured athletes were excluded for this study because of dishonesty about the questionnaires. Therefore, the 225 injured athletes (height M : 177, SD: 15.54; weight M : 68.64, SD: 11.61)’s questionnaires were finally analyzed for this study, and the questionnaires included Sport Anxiety Scale(SAS), Physical Self-Efficacy Scale, Stress Coping Inventory(KASCS), and Rehabilitation Adherence Questionnaire(RAQ). The results of this study were as follows. Firstly, by using difference verification to analyze among anxiety, self-efficacy, coping with stress, and rehabilitation adherence according to background variables, only women showed higher in the focused anxiety variable than men, and individual sport athletes showed higher in the physical self-presented confidence o f physical self-efficacy variable than team sport athletes. Also, the individual sport athletes showed higher in the problem-focused coping variable of coping with stress than the team sport athletes, but the team sport athletes showed higher in the rate of enduring pain variable of rehabilitation adherence than the individual sport athletes. Secondly, self-efficacy showed statistical positive relationship with coping with stress significantly, so the higher level of self-efficacy the athletes have, the more positive and active coping with stress the athletes have. Thirdly, the coping stress showed positive relationship with the rehabilitation adherence, and the coping with stress had mediator effect between self-efficacy and rehabilitation adherence. Therefore, if the injured athletes who participated in the rehabilitation program had higher self-efficacy to cope with stress positively, they also had higher rehabilitation adherence. Fourthly, self-efficacy showed positive relationship with rehabilitation adherence, so the higher self-efficacy the athletes had, the higher will to participate in the rehabilitation program the athletes had. Fifthly, the anxiety showed negative relationship with the rehabilitation adherence, so if the athletes had higher level of anxiety, the will to participate in the rehabilitation program of the athletes got decreased. Finally, as the result of multiple group, structural relationship model of this study could be applied to both gender and events(individual and team sport).

The purpose of this study is to analyze the characteristics of the spin kick moves in Taekwondo and provide necessary information to the university athletes in correcting their moves. It is also a goal of this study to quantify the forms of the kicks in training to maximize the efficiency. Four national varsity players of Taekwondo and four beginners with no award histories from K Univ. were given 6 weeks of training and motor mechanic analysis have been performed with the spin kicks. The conclusions of this study are as follows. 1. The total elapsed time of performing a spin kick move in each group differed significantly. The beginner group's elapsed time for a spin kick was an average of 0.415±0.158, while the national varsity group's spin kick took only 0.283±0.044. Therefore, the national varsity group turned out to show much more speed in spin kicks. Also, the procedures within individual moves of the varsity group appeared to shorten the entire elapsed time of a move compared to those of the beginner group. 2. In performing Step-and-Spin kicks, the two groups showed significant differences in the angles of joints such as the coxa, knee, and ankle. In case of the beginners, they failed to reduce the angle of the coxa joints, and the knee joint were not fully stretched out in the associated movement of Step-and-Spin kicks. Also at the impact, the dorsification of the ankle joint denied that accurate hits on the desired positions. But, as the training went on, the beginners showed improvements in narrowing down the angles. 3. The angular velocity of the coxa joints in both groups while performing a Step-and-Spin kick move, the angular velocities of each joint turned out to be rather higher. Such an outcome with the beginner group might be due to the lack of practices and thereby failure in controlling effective distances while associating each phase of the Step-and-Spin kick. 4. The surface recoil of the beginner group appeared to increase in its value as the training progressed in comparison with the national varsity group. Such a result was found to allow bigger motions when stamping, adding to the force directed upward from the ground. It can contribute to make faster and wider expansion angle movement. 5. In this study, while the Step phase in a Step-and-Spin kick is a precedent but a very important movement before the spin kick is performed, the beginners were found to fail in utilizing this phase efficiently due to lack of techniques.
