Purpose: This study compared isokinetic knee strength profiles by knee surgery history in basketball players. Methods: A total of 17 professional female basketball players (age, 23.7±3.8 years) participated in this study. All the participants performed maximal isokinetic knee strength test concentrically at a velocity of 60°• sec −1 and 180°• sec −1 . Strength variables included peak torque (PT), body mass normalized PT (NPT), bilateral strength difference (BD), hamstrings to quadriceps strength (H/Q) ratio. Independent t-test and one-way analysis of variance were used to compare mean differences in the measured parameters by knee surgery history and limb-based sugroups, respectively. Results: Nine subjects had a history of knee surgery. At all velocities, there were no significant group differences in PTs, NPTs, BDs, and H/Q ratios of the knee extensor and flexor muscles by knee surgery history. Overall, NPTs of knee extensor and flexor muscles were 2.91−3.01 N• m• kg −1 and 1.55−1.59 N• m• kg−1 , respectively, and H/Q ratios ranged from 52% to 55%. At 180°• sec −1 . NPTs of knee extensor and flexor muscles were 1.90−1.92 N• m• kg −1 and 1.08−1.10 N• m• kg −1 , respectively, and H/Q ratios ranged from 57% to 58%. Conclusion The current findings suggested that isokinetic knee strength profiles measured at 60°• sec −1 and 180°• sec −1 velocities were similar regardless of a history of knee surgery in the professional female basketball players.

Purpose: This study aimed to analyze the injury epidemiology of Korean Basketball League (KBL) players. Methods: Exposures and injury data were collected from 19 men’s professional basketball players of a single team who participated in the 2020– 2021 KBL season. Injury data included injured body parts, injury mechanisms, injury diagnoses, activities, playing positions, and time loss. Injury rates (IRs) were calculated using the athletic exposure (AE) method. Results: A total of 49 injuries were reported during the study period. The overall IR was 9.13 per 1,000 AEs and 0.11 per 1,000 time exposures (TEs). Competition IR was 23.9 per 1,000 AEs, and it was approximately 3.9 times higher than practice IR (6.1 per 1,000 AEs). Preseason IR was 2.5 times higher than regular season IR (15.5 per 1,000 AEs and 6.2 per 1,000 AEs, respectively). Ankle was the most frequently injured body part (26.5%), followed by trunk and spine (14.3%), knee (12.2%), and lower legs (12.2%). The majority of the competition injury mechanisms were player contact (54.5%). The majority of the practice injury mechanisms were noncontact (37.0%) and overuse (33.3%). Sprain accounted for the largest proportion with 28.6% overall, followed by strain (22.4%), and low back pain (12.2%). Conclusion KBL professional basketball players experience higher IR during the regular season than in the preseason. The competition IR was higher than the practice IR during the study period. Lateral ankle sprains were the most commonly reported specific injuries.

Purpose: This study aimed to investigate severe knee, ankle, and shoulder injuries in Korean men and women freestyle wrestlers, with a focus on gender comparison. Methods: A total of 90 wrestlers (44 men and 46 women, mean age 25.1±3.9 years) who consented to participation in the study were included as subjects. A standardized questionnaire was used to investigate athletes’ experiences of severe knee, ankle, and shoulder injuries that limited their participation in training or matches for more than 3 weeks during their athletic careers and their postinjury management practices. Results: Severe injuries to the knee occurred in 55.6% of all participants, to the ankle in 34.4%, and to the shoulder in 28.9%. These severe injuries occurred mainly during wrestling technical training due to player contact mechanisms, with a high frequency during tackling movements. Only about half received specialized postinjury rehabilitation, and about 70% returned to training or competition without medical clearance. There were no gender differences in the characteristics of these injuries and their postinjury management. Conclusion The current findings suggest that Korean men and women freestyle wrestlers are likely to suffer severe knee, ankle, and shoulder injuries during their careers, but that postinjury management to ensure a safe return to training is inadequate.

Purpose: This study aimed to examine the experience of severe knee, shoulder, and ankle injuries in elite Korean male wrestlers, focusing on a comparison between Greco-Roman (GR) and freestyle (FS) wrestling. Methods: A total of 90 wrestlers (46 GR and 44 FS aged 24.8±3.7 years) who participated in the national team selection tournament voluntarily participated in this study, selected by random sampling. A standardized questionnaire was used to collect data on severe injuries to the knee, shoulder, and ankle that resulted in a time loss of ≥3 weeks. Results: Approximately 41% of all participants experienced severe injuries to the knee, 21% to the shoulder, and 30% to the ankle. FS wrestlers were significantly more likely to experience severe knee injuries than GR wrestlers (p＜0.001), and they tended to require more time to return to play. Significant differences in specific maneuvers that caused severe knee (p＜0.001), shoulder (p=0.011), and ankle (p=0.002) injuries were observed by wrestling style. Conclusion The current findings indicate that the patterns of severe injuries in wrestling may vary by wrestling style, emphasizing the importance of developing wrestling style-specific injury prevention and management strategies.

Purpose: This study aimed to provide the descriptive statistics regarding the injury epidemiology of Korean professional basketball players. Methods: In this study, athlete exposures (AEs) and time exposures (TEs) were collected from the 38 basketball players (17 women) who participated in the 2019–2020 regular season. Injury rate (IR) and 95% confidence interval (CI) were calculated. Results: A total of 35 injuries were reported. The overall rate of injury was 5.65 per 1,000 AEs and 0.06 per 1,000 TEs. Approximately 65.7% of all the injuries occurred during the official games, with lower limb injuries accounting for about 57.1% of all the injuries. Ankle was the most frequently injured body area (25.7%) with a IR of 1.45 per 1,000 AEs. Sprain accounted for the largest portion with 54.3% overall, followed by strain, contusion and cartilage damage. The most common cause of injuries was contact with another athletes (37.2%), and the recurrence of past injuries (20.0%) also accounted for a high proportion. Conclusion Korean professional basketball players experience a high rate of injuries occurring during official games.Ankle sprains were the most common ones. Contact-caused injuries accounted for the highest portion.
