Nanotechnology, like any other revolutionary innovation in materials science, has significantly influenced the level of competition in sports. Nanotechnology provides various benefits and enormous potential to enhance athletic equipment, making players safer, more comfortable, and more agile. Various sporting equipment is being infused with nanomaterials, including carbon nanotubes (CNTs), silica nanoparticles (SNPs), nanoclays fullerenes, etc., to enhance athlete and equipment performance. Each of these nanomaterials gives athletic equipment an extra benefit like high strength and stiffness, longevity, decreased weight, abrasion resistance, etc. This paper mechanically analysis the structural strength of tennis equipment to avoid injury. As a result, the bending forces are applied to the reinforced structures to investigate their durability.

Purpose: Few studies have been done for spinal injuries after skiing and snowboarding accidents. Assuming that the riding patterns of skiing and snowboarding were different, we analyzed the differences between the mechanisms, diagnoses and levels of spinal injuries caused by them. The purpose of this study was to gain a better understanding of spinal hazards associated with skiing and snowboarding in order to educate skiers and snowboarders. Methods: We conducted a prospective study of 96 patients who had sustained spinal injuries as a result of skiing and snowboarding accidents from January 2003 to March 2006. We used a questionnaire, radiological studies, history taking, and physical examinations. We analyzed the mechanism of injury, the level of spinal injury, the severity of spinal injury, and the Abbreviated Injury Scale scores (AIS score). We used the t-test and the chi-square test. Results: The skiing and the snowboarding injury group included in 96 patients. The skiing injury group included 30 patients (31.2%), and the snowboarding injury group included the remaining 66 patients (69.8%). The primary mechanism of injury in skiing was collisions and in snowboarding was slip downs (p=0.508). The primary level of spinal injury in skiing and snowboarding was at the L-spine level (p=0.547). The most common athlete ability of the injured person was at the intermediate level (p=0.954). The injured were most commonly at the beginner or the intermediate level (p=0.302). The primary diagnosis of spinal injury in skiing and snowboarding was back spain (p=0.686). The AIS scores did not differed between the two groups (p=0.986). Conclusion: The most common spinal injury after skiing and snowboarding accidents was back sprain. There was no difference in the severity of spinal injury between skiing and snowboarding accidents.

국가대표 여자 유도선수를 대상으로 스포츠 손상 발생률과 심박변이도 간의 상관관계를 알아보고자 하였다. 연구 참여자들은 자율신경 진단기(SA-6000)를 사용하여 심박변이도를 측정하였다. 평균 손상 발생률을 기준으로 스포츠 손상 발생률의 상위그룹과 하위그룹으로 분류하였으며, 두 그룹 간의 심박변이도를 알아보기 위해 독립표본 T-test와 스포츠 손상 발생 횟수와 심박변이도의 상관관계를 알아보기 위해 Pearson의 적률상관관계를 시행하였다. 심박변이도는 총 파워와 저주파에서 유의한 차이가 있었으며, 스포츠 손상 발생 횟수에 따른 심박변이도의 상관관계 분석에서도 총 파워와 저주파에서 유의한 차이가 있었다. 이러한 자료들은 향후 선수들의 스포츠 손상 예방프로그램을 만드는데 유용한 기초자료로 제공될 것으로 사료된다.

본 연구는 장애인운동선수들의 스포츠상해유형에 대하여 알아봄으로써 장애인 운동선수들의 상해 예방 및 치료, 관리, 운영방안에 기초적 자료를 제공하고자 한다. 2015년에 전국장애인체육대회에 참가한 선수 171명을 대상으로 스포츠상해관련 설문을 조사하여 다음과 같은 결과를 얻었다. 상해 부위는 어깨, 손가락, 손목 순으로 상해 빈도가 가장 높았으며, 상해 유형으로는 타박상, 근육통, 염좌 순으로 높게 나타났다. 생해기전으로는 선수들과의 접촉, 기구와의 접촉으로 인한 상해가 가장 많이 발생되었다. 상해발생원인으로는 과도한 승부욕으로 인한 상해 발생가 가장 많았으며, 게임 중에 가장 많이 부상을 당한다고 하였다. 만성적 통증 부위 역시 어깨가 가장 많았으며 다음으로는 대퇴, 손목 순으로 나타났다. 상해 직후 처치는 감독이나 코치, 자가 치료가 순으로 가장 많았으며 치료는 파스나 스프레이를 이용한 치료방법이 가장 많았으며, 치료방법은 물리치료가 가장 많았다. 상해 예방방법으로 준비운동과 정리이 필요하다는 응답이 가장 많았으며 그 다음으로는 체력 훈련이 필요하다고 응답하였다. 이상의 결과를 통해, 장애인 선수들의 상해 예방 및 치료, 관리를 위한 체계적이고, 과학적인 체력관리 및 재활훈련 프로그램 제공을 위한 후속연구가 필요하다.

Taping is used to restrict undesired, potentially harmful motion and allow desired motion. Taping refers to the application of some type of adhesive backed tape, that adheres to the skin of a particular joint or to a limb. Prevention and rehabilitation is two main indications for the use of taping techniques. The purpose of this study was to compare a tennis injury between taping and non-taping group. The objects of this study were 64 tennis club members-38 non-taping group, 26 taping group. The analysis methods were both frequency and paired T-test. The results are followings: 1. There was effective increase of taping group-elbow, wrist, knee, ankle-that showed significant increase on statistical analysis. (P<.05). 2. There was effective a relation of seasons and injured in taping group-elbow, wrist, ankle-(P<.05) 3. But non-significant statistically about injured seasons. Prophylactic taping has become one of the most common methods employed to prevent sports injuries, despite questions regarding its efficacy. The success of taping does not only depend upon the materials or methods used, but also upon the phychologic sedative effect of the athlete to be taped.

Safety in sports is important because if an athlete has an accident, he may not be able to lead an everyday life for the rest of his life. The safety of sports facilities is very effective in creating people's sports activities, with the benefits of staying away from physical injury, enjoying sports, and mental peace. Everyone has the right to participate in sports and recreation and to ensure that they want a safe environment. This study prepares a very good Nickel-Cobalt -Silicon carbide (Ni/Co-SiC) nanocomposite with convenient geometry on the leg press machine rod, employing the pulse electrodeposition technique to reduce the rod's wear and increase the durability of sports equipment and control sports damages. The results showed that the Ni/Co-SiC nanocomposite formed at 2 A/dm2 shows extraordinary microhardness. The wear speed for the Ni/Co-SiC nanocomposite created at 4 A/dm2 was 15 mg/min, showing superior wear resistance. Therefore, the Ni/Co-SiC nanocomposite can reduce sports equipment's wear and decrease sports injuries. Ni-Co/SiC nanocomposite layers with various scopes of silicon carbide nanoparticles via electrodeposition in a Ni-Co plating bath, including SiC nanoparticles to be co-deposited. The form and dimensions of Silicon carbide nanoparticles are watched and selected using Scanning Electron Microscopy (SEM).

The purpose of this study was to investigate the distribution of trigger points(TrPs) on athletes with various sporting background. To achieve the purpose, a study was carried out through a survey from 180 athletes involved in 6 selected sports at Yong-In University. Selected sports included Judo, Taekwondo, Kendo, Ssi-reum(Korean traditional wrestling), Boxing, and Golf. An interview type survey and physical examination were conducted with each thirty athletes from each of the selected sports groups. Technical statistic(SPSS 15.0) was used to analyze the distribution of TrPs on these athletes. The most common TrPs observed in muscles of Trapezius, Quadratus Lumborum, Quadriceps in Judo. In Taekwondo, it was on the trapezius and triceps surae. Kendo athletes had TrPs at sites of trapezius, brachioradialis and triceps surae. Ssirem athletes were found to have TrPs on trapezius, deltoid and quadrates lumborum. In boxers, TrPs appearing at trapezius and brachioradialis were observed. Finally, Golf players were seen to have TrPs at trapezius, quadrates lumborum and brachioradialis. Hence, the analysis shows that there are significant differences of the distribution of TrPs according to the different sport items of the athlete.
