PURPOSE: This study examined the incidence, location, and characteristics of sports injuries according to the position in Korean female elite handball athletes. METHODS: Thirty handball athletes, who trained at between January 2019 and December 2019 were enrolled. The event, position, and location of injury were recorded according to the IOC's Daily injury reports form. The incidence of sports injury was examined with the 95% confidence interval (CI), and the difference in the incidence of injury by position was presented as the rate ratio (RR). Moreover, differences in the location of the sports injury according to the position were examined using χ2 tests. RESULTS: A total of 148 sports injuries occurred in the handball players, with an incidence of 22.71 cases of injury per 1,000 exposures (95% CI 19.05 - 26.37) The incidence of injury was highest in the Competition group, followed by the Weights and Training groups. The most common location of sports injury was the lower extremity, followed by the upper extremity, trunk. No significant differences in the location of sports injuries were observed according to the position (p = .384). In addition, the knee, ankle, lumbar spine/lower back, shoulder/clavicle were common sites of sports injury among handball players. CONCLUSION: These results provide a baseline for predicting sports injuries occurring in athletes during games, and would provide useful information for developing performance enhancement as well as injury prevention programs.

PURPOSE: The study examined the relationship between the knee function score and knee strength and muscular endurance of an elite female handball athletes according to their position in the team. METHODS: Thirty handball athletes participated on the study: 12 front positions, 12 back positions, and five goalkeepers. The knee function score consisted of symptoms, pain, daily activity, sports and recreation, and quality of life. In addition, CSMI (Cybex, USA) was used to measure the strength and muscular endurance of the knee. The muscular strength and muscular endurance were measured at an angular velocity of 60°/s and 180°/s, respectively. RESULTS: The overall items of the knee function score showed a significant difference (p = .017), and goalkeepers had significantly higher scores than the back positions. In addition, significant differences were observed in all five items depending on the position (p ≤ .05). On the other hand, both the flexor and extensor muscles of the knee strength and muscular endurance were not significant. Moreover, there was no correlation between the knee function score and the knee strength and muscle endurance. CONCLUSION: Elite female handball athletes have different knee functions score depending on their position in the team, but the, strength and muscular endurance of the knee were similar for each position. Furthermore, the knee function score showed no correlateion with the strength and muscular endurance of the knee.

Objective: The purpose of this study is to investigate whether the athletic knee show greater rotation and translation movement than non-athletic knee during the treadmill walking with their preferred speed in a complete gait cycle. Method: Thirty young and healthy male subjects participated in the study, fifteen handball players (mean age: 19.6 ± 1.4 years old, mean weight: 85 ± 11.9 Kg, mean height: 179.8 ± 4.7) and fifteen non-athletes (mean age: 22.8 ± 1.2 years old, mean weight: 74.5 ± 8.6 Kg, mean height: 175 ± 5.9). Three-dimensional positional coordinate of lower limb during treadmill walking were analyzed. Results: There were significant differences (t (22.014)=1.585, p=0.127 in the range of internal and external rotation with mean value for handball player (M=14.4513, SD=2.3839) was higher than non-athletes (M=13.3327, SD=1.337). The magnitude of the difference in the means (mean difference=1.11867, 95% CI: -0.34489 to 2.5822) was significant. There were also significant differences (t (17.956)=1.654, p=0.116 in the max abduction and adduction with mean value for handball player (M=5.7160, SD=2.49281) was higher than non-athletes (M=4.5773, SD=0.94667). The magnitude of the difference in the means (mean difference=1.138, 95% CI: -0.30805 to 2.58539) was significant. At significance level 0.05. Conclusion: Finding of this study suggest that to understand the actual characteristic of knee motion studies have to be done in different walking and running trial at variable speed.

Purpose : This study compared the differences in power and agility of athletes in each sports using visual response speed test (VRST) scores after conducting 10 weeks of body stability exercise (BSE) on elementary school athletes in handball, football, volleyball and conducted a post-hoc test on the measured values. The subjects of this study were baseball (n=27), taekwondo (n=22), and football (n=23) athletes with at least two years of athletic experience. A total of 72 elementary school athletes were measured by VRST after 10 weeks of BSE under the same conditions. Methods : For VRST measurement of the upper extremity, the right and left hands were alternately touched in the order the blazepod equipment lights were turned on. The number of touches for 15 seconds and response touch were measured. In the case of the measurement of lower extremity the left lower extremity was measured first when the Blaze pod equipment light came on. The average value was obtained by measuring 3 times using a measurement sensor with the position indicated in order to measure the upper arms and legs the same. Results : This study confirmed homogeneity among sports and that VRST improved after implementing BSE for sports. However, no statistically significant difference was identified when comparing VRST improvements between sports, and post-hoc test results showed no significant differences either. Conclusion : After applying the BSE program under the same conditions for 10 weeks to elementary school students who can improve their power and agility the most, the results of the examination using the Blaze pod showed that the power and agility of baseball, taekwondo, and soccer players were similarly improved. From the fact that there was no significant difference among sports, it could be inferred that the BES training program could improve VRST without being limited to some sports.

BACKGROUND/OBJECTIVES: This study examined the differences in psychosocial factors and eating behaviors by the stages of change (SOC) in nutrition management among elementary and middle school athletes. SUBJECTS/METHODS: Subjects were young athletes recruited from the athletic clubs of 10 organizations. Subjects responded to a survey questionnaire, and data on 167 athletes were analyzed. Subjects were grouped into the pre-action or action stage in nutrition management. The χ² test, t-test, analysis of covariance, and correlation analysis were used in data analysis. RESULTS: Athletes in the action stage (62.3%) compared to the pre-action stage, showed a higher self-efficacy (P < 0.01), and felt more confidence in performing specific eating behaviors (P < 0.05 to P < 0.01). Those in the action stage had more favorable beliefs regarding nutrition (P < 0.001) and agreed less strongly on the specific misconceptions/disadvantages of nutrition (P < 0.01) than those in the pre-action stage. Eating behaviors (P < 0.001) and subscales of the eating behaviors (P < 0.05 to P < 0.01) also differed significantly by the SOC group. Place of eating dinner (P < 0.05) and the person who prepares dinner (P < 0.05) showed significant differences by the SOC group. The relationship of self-efficacy, beliefs regarding nutrition, and eating behaviors to the SOC differed by sports type. Beliefs for football athletes, self-efficacy, and beliefs for baseball athletes were correlated significantly with the SOC, whereas all 3 variables were related to the SOC for handball and other athletes. CONCLUSIONS: This study showed differences in psychosocial factors and eating behaviors between the pre-action and action stages. Nutrition education should include strategies to help young athletes modify their beliefs, mainly misconceptions/disadvantages of nutrition, increase self-efficacy, and adopt specific and desirable eating behaviors. Nutrition education might employ different strategies considering the sports type that student-athletes participate.

Jacket is popular ready-made garment among college students in their early 20s. However, ready-made jackets, which are designed to fit normal people, are not likely to fit sportsmen well who have highly developed muscles in particular parts of their bodies. And muscle development is quite different among sportsmen according to the types of sports and bodily movements. Therefore, ready-made jackets can not be expected to fit sportsmen well as they fit normal people who have different shapes of bodies from sportsmen. The purpose of this study is to investigate the factors of fitness and comfortableness of jackets for sportsmen in their early 20s according to the types of sports to provide basic data for designing suitable garments for them. Research method, 362 college sportsmen in their early 20s were surveyed from June 2nd 2009 to June 9th 2009, and 360 of them were processed statistically, with 2 of them having been discarded for lack of sincerity. Among Taekwondo players, Arm Length was the most complained part, among wrestlers, Biacromion Length was the most complained part, among fencers, 'Waist Circumference' was the most complained part, among swimmers, Biacromion Length was the most complained part, among apparatus gymnast, 'Hip Circumference' was the most complained part, among track athletes and handball players, more than 20% answered that the jackets did not fit them in every parts. It was understood that different sportsmen complained of particular parts of the jackets and that parts of the jacket should be adjusted according to bodily shapes of different sportsmen. This study was made to investigate the factors to be considered in producing ready-made jackets for college sportsmen. It is hoped that more patterns will be developed on the basis of the original form of jacket and the result of this study.
