The purpose of this study was to describe the epidemiology of Korean collegiate injuries during 2015. Collegiate student-athletes(n=167) in six sports (badminton, baseball, basketball, rugby, taekwondo, and volleyball) participating in all practices and games during pre-season, in-season, and post-season were tracked via the injury surveillance system(rate, location, type, and cause of musculoskeletal injury). Injury rate for 1000 athlete-exposure(AE) and 1000 time-exposure(TE) were calculated with 95% confidence intervals(CI). We captured a total of 961 injuries, a rate of 19.29/1000 AE(95% CI=18.07, 20.51) and 0.16/1000 TE(95% CI=0.15, 0.17). Commonly injured body locations were knee(17.5%, n=168), thigh(16.1%, n=155), ankle(12.1%, n=116), and finger(8.4%, n=81). Injuries were mostly diagnosed as contusion(40.1%, n=385), ligament sprain(21.1%, n=203), and laceration/abrasion/skin injury(13.5%, n=130). Common causes were contact with another athlete(44.6%, n=429), contact with moving object (12.7%, n=122), overuse/atraumatic(11.9%, n=114), and contact with non-yielding object(9.4%, n=90).
Purpose The purpose of this study is to examine the location, rate, cause, and types of injuries according to the injured area by age and sports in female athletes. Methods The subject of the study was 426 female athletes who were registered as combat sports(Judo, Taekwondo, Fencing) athletes at the Korean Sports & Olympic Committee. We collected the data via online questionnaires, and conducted a frequency analysis using R statistics program. Results As a result, 51.4% of athletes experienced injuries in the past year, and the highest injury rate was shown in Taekwondo-University(0.43) during competition and Taekwondo-Professional(5.55) during training. The cause of injuries during competition was mainly due to 'as a result of me or the opponent's hittings, skills, or fouls' among internal factors, and 'recurrent injuries' among external factors. Among internal factors during training except for torso area and professional athletes, most of the injuries were also caused by ‘as a result of me or the opponent's hittings, skills, or fouls’ and ‘recurrent injuries’ among external factors. The frequency of injury was the highest in the lower extremity area across all age groups. The most frequently injured area, in the case of Judo, is skin-bleeding in the head, skin-bruise, muscle-inflammation, bone-fracture, spondylopathy(disc, stenosis, etc.) in the torso, muscle-inflammation in the upper extremity, ligament-sprain, rupture in the lower extremity. Taekwondo athletes had skin-bruise in the head, upper and lower extremities, and muscle-inflammation in the torso area, as the frequent injury cases, and Fencing athletes had all skin-bruise regardless of injuries. Conclusions The results of this study will be used to take measures for preventing injuries or to change training programs.
PURPOSE The purpose of this study was to investigate the current injury status and traits, including damage area, cause of damage based on the situation, and type of occurrence by age group for middle and high schools, university, and professional athletes, in record competition sports (swimming, track and field, and weightlifting). METHODS The study included 503 athletes enrolled in the Korean Sport & Olympic Committee in 2020, and an online survey was conducted using the R statistical program. RESULTS Approximately 38.4% athletes suffered injuries with weightlifting (0.81 times at university) and weightlifting (7.02 times at university) during training. The lower extremities were the most affected areas in all age groups (53.8% in middle school, 48.6% in high school, 44.4% in university, and 47.4% in professional). The causes of damage found to occur most frequently were ‘lack of physical strength, overuse or lack of rest, and recurrence’ and external factors, including ‘facility programs and weather problems.’ The results showed that internal factors during training were mostly associated with ‘overuse or lack of rest and excessive attempts at skills’, while external factors were found to occur in ‘weather problems’. According to the classification of each event, the top priority of frequent damage according to the damaged area was skin bleeding of the head in swimming and muscle inflammation in the torso and upper and lower extremities. Track and field resulted in muscle inflammation in the head, torso, and upper and lower extremities. Weightlifting caused damage to the head and torso, resulted in spinal diseases (disc, spinal stenosis, etc.), and muscle inflammation in the upper and lower extremities. CONCLUSIONS This study highlighted changes in the training environment and training environment, including level-specific physical training, reinforcement programs, scientific access to specific skills, sufficient rest and recovery, and continuous improvement of facilities and equipment.
PURPOSE The purpose of this review was to summarize the current knowledge on the trends in athletes’ health problems (and their preventive strategies) caused by low energy availability (LEA) and relative energy deficiency in sports (RED-S). METHODS In this narrative review, we summarized previous studies by searching the literature in the PubMed, Google Scholar, and Science Direct databases. RESULTS Energy availability (EA) refers to the amount of energy from caloric intake used for exercise, and a LEA is considered as a surrogate marker of RED-S. In several previous studies, chronic low energy availability in female athletes has been reported to cause health problems such as endocrine dysfunctions, immunosuppression, and psychological disorders, and to also affect the hypothalamic-pituitary-gonadal (HPC) axis and bone health. Moreover, it has been suggested that an increase in injury risk and a decrease in exercise performance may occur. CONCLUSIONS Since it can be difficult to recover from the health deteriorations caused by RED-S, early detection (of related signs and symptoms) and prevention are very important. Therefore, athletes, coaches, and parents need to develop educational programs that ease the recognition of the problems caused by various symptoms related to RED-S and promote educational interventions.
