  • This study investigated the influence of media sports contact motivation on direct sports participation in order to induce direct sports participation through media sports. In this regard, this study aimed to provide the basic data of media sports and sports participation by studying the effects of consumer's exercise commitment and exercise duration. From April 1, 2019 to April 31, 2019, a survey was conducted on 300 males and females in G and J provinces. To determine the purpose of the study, IBM's SPSS Ver. 21.0 and AMOS Ver. The analysis was performed using a statistical program of 21.0. The results of the study are as follows. First, media sport contact motivation was found to have an effect on exercise commitment. In addition, media sports contact motivation was found to have an effect on exercise persistence and sports participation. In addition, exercise commitment was found to have an effect on exercise duration, and exercise duration was found to affect sports participation. Second, in terms of media sports contact motivation and sports participation, exercise persistence had a mediating effect. In addition, it was found that exercise commitment had a mediating effect on the relationship between media sports contact motivation and exercise persistence, and exercise persistence had a mediating effect on the relationship between exercise commitment and sports participation. Third, media sports contact motivation did not have a direct effect on sports participation. Also, exercise immersion has no mediating effect in the relationship between media sports contact motivation and sports participation. However, in terms of media sports contact motivation and sports participation, exercise commitment and exercise persistence showed a double mediating effect.

  • Statement of problem: In spite of increasing sports injury, there was no collected data on the rate and type of dental injuries for athletes in Korea. Purpose: The purpose of this study was to investigate the occurrence of maxillofacial injuries and attitude of college sports player in Korea towards mouthguard. Material and methods: Total 617 athletes answered a series of questionnaire concerning their sports injury and using mouthguard. Results: 1. 81%(502) of athletes had, playing or training a sports, suffered an injury. Female athletes suffered an injury more than male athletes(p<0.05). Contact sports athletes were injured more than non contact sports athletes(p<0.05). 2. 335 athletes(54.8%) had suffered maxillofacial injuries while playing or training. 81.8% of athletes suffered an maxillofacial injury in contact sports(p<0.05). 3. Laceration of oral area, wrick in neck, fracture or avulsion on upper incisors, concussion, TMJ injury, fracture or avulsion on lower incisors, fracture or avulsion on lower molars were frequently injured area. 4. 67.2% of athletes answered that mouthguard could prevent sports injury especially high in contact sports(p<0.05). But only 39.1% of athletes required mouthguard while playing. 44.6% of athletes showed their intention of using mouthguard. Conclusion: This study shows that the incidence of maxillofacial injuries is very high while the actual use of mouthguard is very low. To prevent sports injury, a dentist must inform sports players and coaches of accurate information about mouthguard so that they can use it well. A dentist also has to provide them with better mouthguard on the basis of user's complaint.

  • The aims of this retrospective study were to evaluate the results of inferior capsular shift operation which were approached anteriorly or posteriorly according to a main instability direction in contact sports population who had multidirectional shoulder instability. Fifty-three shoulders in 47 athletes who engaged in contact sports underwent an anterior or posterior inferior capsular shift procedure for the correction of multidirectional instability of the shoulder joint. The surgical approach was selected according to the predominant direction of the instability. Follow up was average of 42 months(24∼73 months). After anterior inferior capsular shift, anterior dislocation was recurred in three shoulders, posterior dislocation in one, and inferior dislocation in two shoulders. After posterior inferior capsular shift, one dislocation occurred anteriorly, one inferiorly and one posteriorly. The excessive tightening of capsule or improper diagnosis could be causative factors for the development of dislocation in the opposite direction to the preoperative major instability. Of six patients who could not return to their sports, five had bilateral repairs. Successful repair based on the criteria of the American shoulder and elbow association was achieved in 92% of anterior repairs, and 81 % of posterior repairs.

  • This study was accompolished to analyze and compare the number and area of the occlusal contact points in healthy volunteers and athletes with normal occlusion. Before the study, 89 athletes(sports career:8.6 years, average age 20) at Kyung Hee University were selected, and survey was accomplished for athlete's recognition about sports dentistry. For this study, 15 athletes(13 amles and 2 females with average age 20) and 21 healthy volunteers(14 mles and 7 females with average age 20.09) at Kyung Hee University were selected. The visual display acquired by scanning of occlusal record in maximal intercuspation was converted into 16 gray value image. Then, using computer program(J & Lee Occlusal Analyser), the pixel which was in definite range of the gray value was recognized, and the numbers of recognized pixel were calculated to area. The results were as follows : (1) On the survey about sports dentistry, 28% of 89 athletes didn't agree that human occlusion may be important, and 30% didn't have any idea of the influence of human occlusion during their sports activities. (2) The average numbers of total occlusal contact points were 31.05 in control group, and 34.67 in athlete group. The average area of total occlusal contacts was $100.25mm^2$ in control group, and $127.78mm^2$ in athlete group. (3) In control group, the average numbers of occlusal contact points were revealed in order as follows; the first molar(8.48), the second molar(8.24), the second premolar(4.71), the lateral incisor(2.90), the first premor(2.43), the central incisor(2.19), and the canine(2.1). The least average in canine(2.1) was similar to the average(2.19) in central incisor and (2.09) in lateral incisor. In athlete group, the average numbers of occlusal contact points were revealed in order as follows; the first molar(8.87), the second molar(8.47), the second premolar(5.60), the canine(3.80), the lateral incisor(3.33), the first premolar(2.67), and the central incisor(1.93). (4) In control group, the average areas of occlusal contact surface were revealed in order as follows; the first molar($39.47mm^3$), the second molar($37.54mm^3$), the second premolar($9.54mm^3$) the first premolar($6.18mm^3$), canine($3.49mm^3$), the central incisor($2.76mm^3$), and the lateral incisor($1.28mm^3$). In athlete group, the average areas of occlusal contact surface were revealed in order as follows; the first molar($44.11mm^3$), the second molar($40.69mm^3$), the second premolar($16.50mm^3$), the first premolar($9.39mm^3$), the canine($5.08mm^3$), the lateral incisor($3.7mm^3$), and the central incisor($2.25mm^3$). (5). With aging in both control and athlete group, there was a decreasing tendancy in average number of occlusal contact point, and was an increasing tendancy in average area of occlusal contact surface. In comparison at each age, both the numbers and area of occlusal contact were greater in athlete group than in control group. It was not significant in the numbers of occlusal contact points beween athlete and control group(p>0.1), but significant in the area of occlusal contact surface(p<0.05). (6) In comparision as to the kind of sports(Gymnastics:2, Rugby:3, Soccor:5, Ice hocky:5), the numbers of occlusal contact points were the most in ice hocky, and the area of occlusal contact surface was the greatest in gymnastics. With increasing a career in athlete group, there was a decreasing tendancy in average numbers of occlusal contact points, and was an increasing tendancy in average area of occlusal contact surface.

  • The purpose of this research helps to make full use for perfect performance by grasping the defects of Ropez motion performed by athlete CSM who was under the training for the 28th 2004 Athene Olympic Garnes, and by presenting complementary methods. For the better Ropez motion which had been performed by CSM for the 1st dispatch selection test and the final for the 28th Athene Olympic Game was analyzed with 3-dimensional cinematographic method. Here are the conclusions: 1. During the board contact phase, powerful kicking and rapid forward flexion motion of upper body make increasing vertical velocity of C. O. G and enlarging body angle. 2. It was indicated that rapid forward flexion motion of upper body during the board contact phase get a large body angle in horse take-off. 3. rapid forward flexion motion of upper body during the board contact phase makes a longer time at horse contacting phase. It showed that this result increased velocity of horse take-off causing by powerful blocking motion. 4. Increasing of air-borne height during pre- flight phase, makes a higher C. O. G; and larger angle of hip, angle of knee and body angle in the landing phase. And it revealed that these results have a stable landing.
