The aim of this explorative study was to determine the most effective physical training program to reduce neuromuscular risk factors of Anterior Cruciate Ligament (ACL) tear and to improve jumping performance. Twentyfour female basketball players were divided into three groups: Specific Physical Training Group (SPTG), combined specific Physical and Mental Training Group (PMTG) and Control Group (CG). The training program was conducted over a period of eight weeks including two sessions per week during basketball practice. Dynamic valgus, Peak Vertical Impact Force (PVIF), Rate of Force Development (RFD), and jumping performance were measured at pre-and posttests. When all the participants were pooled, statistics showed a decrease (-36%) in dynamic valgus. No significant results were observed for PVIF and RFD. Jumping performance improved by 12% in SPTG and remained constant in PMTG and CG. Adding specific physical training to basketball practice should be the most effective program to prevent ACL tear while improving jumping performance in young female basketball players.
ACL Injury Prevention: What Does Research Tell Us?
Current Reviews in Musculoskeletal Medicine, 2017
Purpose of Review Mechanisms leading to anterior cruciate ligament (ACL) injury have been identified, yet re-injury or a secondary injury persists in the athletic population. The purpose of this review is to identify risk factors associated with ACL injury and investigate programs to prevent injury. Recent Findings Faulty mechanics during dynamic movement that cause excessive valgus force at the knee increases the risk of ACL injury. Faulty mechanics may be a result of lateral displacement of the trunk, unequal limb loading, and lack of control to avoid the valgus knee position. Altered movements that place the ACL at risk are best identified in a fatigued state; however, could be recognized in a standard dynamic assessment. The faulty movement patterns are modifiable and should be addressed in an injury prevention program. Prevention programs include various modes of exercise such as plyometrics, neuromuscular training, and strength training. Summary This review concludes that those programs which utilize neuromuscular training and strength training at a young age show the most promise in reducing ACL injuries. An ongoing thorough dynamic examination is necessary for all athletes while adjusting the intervention program in order to decrease the risk of ACL injury.

This prospective cohort study aims to assess the overall incidence of acute and overuse basketball injuries and identifies risk factors associated with ankle sprains and knee overuse injuries. In total, 164 senior players (23.7 years ± 7.0) of all levels of play, and including both men and women, participated voluntarily during one season. A total of 139 acute and 87 overuse injuries were reported, resulting in an overall injury incidence of 9.8 (8.5 to 11.1) per 1,000 hours. The incidence of acute injuries was 6.0/1,000 hours. Ankle sprains (n = 34) accounted for most acute injuries, and 52.9% of all players with ankle sprains reported a previous ankle sprain. Relative Risks (RR) and Odds Ratio (OR) with their 95% Confidence Intervals (CI) were calculated to determine significant differences. Landing on an opponent's foot was the major inciting event, significantly more so than non contact mechanisms (RR=2.1 [95% CI: 1.0-4.2]). Acute knee injuries resulted in the highest playin...

The purpose of the present study was to determine of some risk factors influencing of non-contact Anterior Cruciate Ligament (ACL) injury in Soccer, basketball and Taekwondo players. If an athlete injured anterior cruciate ligament the most important thing is to identify factors that affect the injury. However, a growing research implicates hormonal, anatomical, environmental and neuromuscular factors that may predispose athletes to these injuries. For this research selected 510 athlete for assess ACL injury factors by two different methods (A) Questionnaire and (B) Interview that information collected among athletes who were play soccer, basketball and taekwondo. Our results indicate 61.4% of ACL injury occurred in practice time and 38.6% of ACL injury was during competition. Also our finding showed that 69% mechanism of injury was non-contact, 4.7% via accident and 26.3% with unknown reason. Furthermore dynamic alignment at the time of the injury included: Knee-in & Toe- out 44%, ...

The research results referring to frequency have indicated that most of the sports injuries among athletes of both genders occur in basketball and that knee injury is the second most frequent injury during sports activities. The anterior cruciate ligament (ACL) represents one of the four most important connections for knee stability, and it is frequently prone to injury during sports activities. The aim of this paper was to determine the effects of an exercise program on the prevention of injury to the anterior cruciate ligament of the knee joint among young female basketball players. To collect existing research on the effects of the applications of prevention programs on the prevention of ACL injury in young female basketball players, the following electronic databases were searched: PubMed, SCIndeks, PEDro, J-GATE, DOAJ and Google Scholar. The analyzed studies were published between 2003 and 2018 and the participants were young female basketball players. According to the results of this study, the most frequently used training programs were neuromuscular programs, whose structure includes several types of exercises and which represented a combination of plyometric exercises, core strengthening exercises, exercises to strengthen the muscles of the lower extremities, agility exercises, flexibility exercises, and balance exercises. Finally, the application of the knee injury training program leads to an improvement in motor balance, proprioceptive abilities, balance, flexibility, as well as biomechanical abilities related to injuries of the ACL, leading to an improvement in sports performance among female basketball players.

Background: Few prospective studies have investigated the biomechanical risk factors of anterior cruciate ligament (ACL) injury. Purpose: To investigate the relationship between biomechanical characteristics of vertical drop jump (VDJ) performance and the risk of ACL injury in young female basketball and floorball players. Study Design: Cohort study; Level of evidence, 3. Methods: At baseline, a total of 171 female basketball and floorball players (age range, 12-21 years) participated in a VDJ test using 3-dimensional motion analysis. The following biomechanical variables were analyzed: (1) knee valgus angle at initial contact (IC), (2) peak knee abduction moment, (3) knee flexion angle at IC, (4) peak knee flexion angle, (5) peak vertical ground-reaction force (vGRF), and (6) medial knee displacement. All new ACL injuries, as well as match and training exposure, were then recorded for 1 to 3 years. Cox regression models were used to calculate hazard ratios (HRs) and 95% CIs. Result...

The study aimed to determine prospectively a basketball injury profile, including severity of injury, and to compare the injury profile by gender and standard of competition. Trained observers viewed basketball games, noting the occurrence of injuries, and confirmed injuries by questioning all players on site after the game. Injured players completed a questionnaire and the progress of their injury was monitored by telephone interview. A total of 10,393 basketball participations were observed. An overall injury rate was documented of 18.3 per 1,000 participations (24.7 per 1,000 playing hours), and was comparable by gender and standard of competition. Serious injuries (missing one or more weeks of play) occurred at a rate of 2.89/1,000 participations; with the ankle joint the most common serious injury {1.25/1,000 participations), followed by the calf/anterior leg (0.48/1,000 participations) and knee joint (0.29/1,000 participations). The severity of the injury was significantly associated with the body region injured, with more serious injuries incurred to the lower limb than other body regions (p <.05). The severity of the injury incurred was not related to the standard of competition, gender, age, height, number of games played per week, amount of training undertaken, type of injury, or the mechanism of injury (p> .05).
