본 연구는 운동부 지도자들이 운동선수들의 기량을 향상시키기 위하여 효율적으로 기록관리 할 수 있는 스마트폰 어플리케이션을 설계하고 구현한 것이다. 운동선수들이 기량을 향상시키기 위해서는 실전과 같은 훈련을 하여야 하며 그에 대한 방안으로 기구, 시설, 장비, 상황 등에 맞추어 훈련하는 방법도 있겠지만, 훈련 시 달성한 기록을 체크하여 운동선수에게 기록에 대한 동기부여를 하는 방안도 생각할 수 있다. 본 연구에서는 유소년 농구클럽을 대상으로 사전 조사를 통하여 실제 농구경기에서 쓰이는 기록관리 시스템으로 운동을 하였을 때와, 그렇지 않았을 때 경기 기록 활용이 동기 부여가 되는 것을 확인하였다. 그리하여 스마트폰 기반 기록관리 어플리케이션을 설계하고 개발하였으며, 이 시스템을 이용한 후 지도자들의 설문조사를 통하여 훈련 효율성을 측정한 결과 실력향상을 위한 동기부여가 있는 것으로 나타났다.

PURPOSE: This study examined the incidence, location, and characteristics of sports injuries according to the position in Korean female national field hockey athletes. METHODS: Eighteen female national field hockey athletes (two goal keepers, five forwards, six midfielders, and five defenders) who trained at the national training center between January 2018 and December 2018 were enrolled. The event, position, and location of injury were recorded per IOC's daily injury reports form. The incidence of sports injuries was examined with the 95% confidence interval (CI), and the difference in the incidence of injury according to the position was presented as the rate ratio (RR). Moreover, differences in the location of sports injury according to the position were examined using χ2 tests. RESULTS: A total of 92 sports injuries occurred among field hockey players, with an incidence of 6.47 cases per 1,000 hours of training (95% CI 4.98-7.96). In addition, 29.12 cases of injuries occurred per 1,000 exposures (95% CI 23.17-35.07), and the incidence of injury was highest among the defenders, followed by forwards, midfielders, and goal keepers. The most common location of sports injury was the lower extremity, followed in order by the trunk, upper extremity, head, and neck, and there were significant differences in the location of the sports injury according to the position (p=.046). In addition, lumbar spine/lower back, thigh, ankle, lower leg, knee, and foot/toe were common sites of sports injury among female field hockey players. CONCLUSION: These results provide a baseline for predicting sports injuries in athletes during games, and would provide useful information for developing performance enhancement and injury prevention programs.

Objective: The bobsleigh shoes used in the start section are one of the most important equipment for improving the competition. Despite the importance of the start section, there are no shoes that are specific for bobsleigh athletes in Korea and Korean athletes have to wear sprint spike shoes and practice the start instead of wearing bobsleigh shoes. The objective of the present study was to provide data for improving the performance of Korean bobsleigh athletes by investigating the differences in their split time, plantar pressure, and forefoot bending angle based on skill levels at the start of a run under the same conditions as training conditions. Method: Six Korean bobsleigh athletes were divided into two groups, superior (n=3) and non-superior (n=3). A digital speedometer measured the split time at the start; the Pedar-X system (Novel, Germany) measured plantar pressure. Plantar pressures and split times were measured as the athletes pushed a bobsleigh and sprinted at full speed from the start line to the 10-m mark on the bobsleigh track. An ultra-high-speed camera was used to measure the forefoot bending angle during the start phase. Results: Significant between-group differences were found in split times (p<.000; superior = 2.38 s, non-superior = 2.52 s). The superior group had a larger rearfoot (p<.05) contact area, maximum rearfoot force (p<.01), and a larger change in angles 3 and 4 (p<.05). Conclusion: At the start of a bobsleigh run, proper use of the rearfoot for achieving effective driving force and increasing frictional resistance through a wider frictional force can shorten start time.

Serum lipid and lipoprotein levels are influenced by genetic factors, and exorcise increases the concentrations of cardio-protective parameters such as high-density lipoprotein cholesterol (HDL-cholesterol) and apolipoproteinAI (apoAI) in human serum. In the present study, we tested the effect of adaptation to endurance exercise on the association of a genetic polymorphism (Pst 1 RFLP) in the apoAI gene with these biochemical parameters. The genotype and allele frequencies for the Pst 1 RFLP were not significantly different between the elite athletes and sedentary controls (P>0.05). There were also no significant associations between the Pst 1 RFLP of the apoAI gene and the biochemical parameters in elite athletic group. Thus, our results suggest that the Pst 1 RFLP of the apoAI gene was not significantly associated with the serum apoAI and HDL-cholesterol concentrations as well as athletic performance in Koreans.
