To assess the effectiveness of exercise-based injury-prevention programs in preventing sports injuries in team handball players. Scopus, PubMed, Web of Science, SPORTDiscus, and CINAHL from inception until April 2023. Studies were included if they were randomized controlled trials or prospective cohort studies, contained a population of competitive team handball players, included an intervention designed specifically to prevent or reduce the risk of team handball injuries, and reported injury incidence rates specific to team handball players. Two researchers independently evaluated studies for inclusion and assessed their methodological quality. Study design, intervention details, participant characteristics, and the number of injuries in each group were extracted from each study by 2 independent researchers. The outcome of interest was the incidence rate of injury. Injury data were classified into 5 groups: shoulder injuries, lower extremity injuries, knee injuries, anterior cruciate ligament injuries, and ankle injuries. Extracted data were analyzed using a random-effects model to compute the overall effect estimates of injury-prevention programs in reducing the risk of injuries. Odds ratios (ORs) with 95% CIs were calculated based on the number of injuries in each group. Meta-analyses were conducted independently for each injury classification. Results indicated that prevention programs reduced the risk of shoulder injuries (OR = 0.60; 95% CI = 0.42, 0.85; P = .004), lower extremity injuries (OR = 0.59; 95% CI = 0.37, 0.95; P = .03), knee injuries (OR = 0.53; 95% CI = 0.35, 0.78; P = .002), anterior cruciate ligament injuries (OR = 0.66; 95% CI = 0.45, 0.96; P = .03), and ankle injuries (OR = 0.57; 95% CI = 0.40, 0.81; P = .002) in team handball players. In team handball players, injury-prevention programs appear to effectively reduce the risk of shoulder, lower extremity, knee, ankle, and anterior cruciate ligament injuries.

Research questionDoes the Nordic hamstring exercise (NHE) prevent hamstring injuries when included as part of an injury prevention intervention?DesignSystematic review and meta-analysis.Eligibility criteria for selecting studiesWe considered the population to be any athletes participating in any sporting activity, the intervention to be the NHE, the comparison to be usual training or other prevention programmes, which did not include the NHE, and the outcome to be the incidence or rate of hamstring injuries.AnalysisThe effect of including the NHE in injury prevention programmes compared with controls on hamstring injuries was assessed in 15 studies that reported the incidence across different sports and age groups in both women and men.Data sourcesMEDLINE via PubMed, CINAHL via Ebsco, and OpenGrey.ResultsThere is a reduction in the overall injury risk ratio of 0.49 (95% CI 0.32 to 0.74, p=0.0008) in favour of programmes including the NHE. Secondary analyses when pooling the eight randomised control studies demonstrated a small increase in the overall injury risk ratio 0.52 (95% CI 0.32 to 0.85, p=0.0008), still in favour of the NHE. Additionally, when studies with a high risk of bias were removed (n=8), there is an increase of 0.06 in the risk ratio to 0.55 (95% CI 0.34 to 0.89, p=0.006).ConclusionsProgrammes that include the NHE reduce hamstring injuries by up to 51%. The NHE essentially halves the rate of hamstring injuries across multiple sports in different athletes.Trial registration numberPROSPERO CRD42018106150.

Background Hamstring injuries are among the most common non-contact injuries in sports. The Nordic hamstring (NH) exercise has been shown to decrease risk by increasing eccentric hamstring strength. Objective The purpose of this systematic review and meta-analysis was to investigate the effectiveness of the injury prevention programs that included the NH exercise on reducing hamstring injury rates while factoring in athlete workload. Methods Two researchers independently searched for eligible studies using the following databases: the Cochrane Central Register of Controlled Trials via OvidSP, AMED (Allied and Complementary Medicine) via OvidSP, EMBASE, PubMed, MEDLINE, SPORTDiscus, Web of Science, CINAHL and AusSportMed, from inception to December 2015. The keyword domains used during the search were Nordic, hamstring, injury prevention programs, sports and variations of these keywords. The initial search resulted in 3242 articles which were filtered to five articles that met the inclusion criteria. The main inclusion criteria were randomized controlled trials or interventional studies on use of an injury prevention program that included the NH exercise while the primary outcome was hamstring injury rate. Extracted data were subjected to meta-analysis using a random effects model. Results The pooled results based on total injuries per 1000 h of exposure showed that programs that included the NH exercise had a statistically significant reduction in hamstring injury risk ratio [IRR] of 0.490 (95 % confidence interval [CI] 0.291–0.827, p  = 0.008). Teams using injury prevention programs that included the NH exercise reduced hamstring injury rates up to 51 % in the long term compared with the teams that did not use any injury prevention measures. Conclusions This systematic review and meta-analysis demonstrates that injury prevention programs that include NH exercises decrease the risk of hamstring injuries among soccer players. A protocol was registered in the International Prospective Register of Systematic Reviews, PROSPERO (CRD42015019912).

ObjectiveTo evaluate the effects of injury prevention programmes on injury incidence in any women’s football code; explore relationships between training components and injury risk; and report injury incidence for women’s football.DesignSystematic review and meta-analysis.Data sourcesNine databases searched in August 2019.Eligibility criteriaRandomised controlled trials evaluating any injury prevention programme (eg, exercise, education, braces) were included. Study inclusion criteria were: ≥20 female football players in each study arm (any age, football code or participation level) and injury incidence reporting.ResultsTwelve studies, all in soccer, met inclusion criteria, with nine involving adolescent teams (aged <18 years). All studies (except one) had a high risk of bias. Eleven studies examined exercise-based programmes, with most (9/11) including multiple (≥2) training components (eg, strength, plyometric, balance exercises). Multicomponent exercise programmes reduced overall (any reported) injuries (incidence rate ratio (IRR) 0.73, 95% CI 0.59 to 0.91) and ACL injuries (IRR 0.55, 95% CI 0.32 to 0.92). For exercise-based strategies (single-component and multicomponent), hamstring injuries were also reduced (IRR 0.40, 95% CI 0.17 to 0.95). While exercise-based strategies resulted in less knee, ankle and hip/groin injuries, and the use of multiple training components was associated with greater reductions in overall and knee injuries, further studies would be required to increase the precision of these results. The incidence of overall injuries in women’s football was 3.4 per 1000 exposure hours; with ankle injuries most common.ConclusionIn women’s football, there is low-level evidence that multicomponent, exercise-based programmes reduce overall and ACL injuries by 27% and 45%, respectively.PROSPERO registration numberCRD42018093527.

ObjectiveInvestigate prevention interventions and potential modifiable risk factors (MRFs) for female/woman/girl athletes’ spine, chest, abdominal or pelvic injury and/or pain.DesignSystematic review with meta-analyses, semiquantitative analyses and Grading of Recommendations Assessment, Development and Evaluation.Data sourcesMEDLINE, CINAHL, APA PsycINFO, CDSR, CENTRAL, SPORTDiscus, EMBASE, ERIC.EligibilityPrimary data studies with comparison group(s) assessing the association of prevention interventions and/or MRFs for spine, chest, abdominal and/or pelvic injury/pain with ≥1 female/woman/girl athlete in each study group.ResultsAcross 105 studies (n=11 interventions, n=92 MRFs, n=2 both, n=35 female/woman/girl-specific estimates) including 59 833 participants (23.7% females/women/girls) 9 injury/pain outcomes were assessed (n=74 low-back, n=14 back, n=13 neck, n=5 pelvis, n=3 thoracic, n=3 abdominal, n=3 trunk, n=2 rib, n=1 breast). Three prevention strategies (exercise, equipment, rule-change) and 22 MRFs were identified. High risk of confounding bias (Downs and Black quality assessment tool) was present in 92% and 63% of intervention and MRF studies, respectively. Considering female/woman/girl estimates, we performed meta-analyses (standardised mean-difference) on 4 MRFs (body mass, body mass index (BMI), weekly training hours, spinal flexion) for low-back pain (LBP) and semiquantitative analyses for one intervention (exercise), and 3 MRFs (yearly training load, hip motion, hip strength) for LBP. Very low-certainty evidence suggests no difference in body mass (g=0.28, 95% CI −0.06 to 0.62; I2=67.7%), BMI (g=0.22, 95% CI −0.25 to 0.69; I2=68.2%), weekly training hours (g=0.15, 95% CI −0.29 to 0.58; I2=45.6%) or spinal flexion (g=0.27, 95% CI −0.23 to 0.76; I2=40.4%) between female/women/girls athletes with and without LBP.ConclusionsThere is limited knowledge about prevention interventions or MRFs for female/women/girl athletes’ spine, chest, abdominal and/or pelvic injury/pain.PROSPERO registration numberCRD42024479654.

To provide certified athletic trainers, physicians, and other health care and fitness professionals with recommendations based on current evidence regarding the prevention of noncontact and indirect-contact anterior cruciate ligament (ACL) injuries in athletes and physically active individuals.   Preventing ACL injuries during sport and physical activity may dramatically decrease medical costs and long-term disability. Implementing ACL injury-prevention training programs may improve an individual's neuromuscular control and lower extremity biomechanics and thereby reduce the risk of injury. Recent evidence indicates that ACL injuries may be prevented through the use of multicomponent neuromuscular-training programs.   Multicomponent injury-prevention training programs are recommended for reducing noncontact and indirect-contact ACL injuries and strongly recommended for reducing noncontact and indirect-contact knee injuries during physical activity. These programs are advocated for improving balance, lower extremity biomechanics, muscle activation, functional performance, strength, and power, as well as decreasing landing impact forces. A multicomponent injury-prevention training program should, at minimum, provide feedback on movement technique in at least 3 of the following exercise categories: strength, plyometrics, agility, balance, and flexibility. Further guidance on training dosage, intensity, and implementation recommendations is offered in this statement.

BackgroundShoulder problems are highly prevalent among elite handball players. Reduced glenohumeral rotation, external rotation weakness and scapula dyskinesis have been identified as risk factors.AimEvaluate the effect of an exercise programme designed to reduce the prevalence of shoulder problems in elite handball.Methods45 elite handball teams (22 female teams, 23 male teams, 660 players) were cluster randomised (22 teams, 331 players in the intervention group, 23 teams, 329 players in the control group) and followed for 1 competitive season (7 months). The Oslo Sports Trauma Research Center (OSTRC) Shoulder Injury Prevention Programme, an exercise programme to increase glenohumeral internal rotation, external rotation strength and scapular muscle strength, as well as improve kinetic chain and thoracic mobility, was delivered by coaches and captains 3 times per week as a part of the handball warm-up. The main outcome measures, prevalence of shoulder problems and substantial shoulder problems, were measured monthly.ResultsThe average prevalence of shoulder problems during the season was 17% (95% CI 16% to 19%) in the intervention group and 23% (95% CI 21% to 26%) in the control group (mean difference 6%). The average prevalence of substantial shoulder problems was 5% (95% CI 4% to 6%) in the intervention group and 8% (95% CI 7% to 9%) in the control group (mean difference 3%). Using generalised estimating equation models, a 28% lower risk of shoulder problems (OR 0.72, 95% CI 0.52 to 0.98, p=0.038) and 22% lower risk of substantial shoulder problems (OR 0.78, 95% CI 0.53 to 1.16, p=0.23) were observed in the intervention group compared with the control group.ConclusionsThe OSTRC Shoulder Injury Prevention Programme reduced the prevalence of shoulder problems in elite handball and should be included as a part of the warm-up.Trial registration numberISRCTN96217107.

Acute kidney injury (AKI) is a common, heterogeneous, multifactorial condition, which is part of the overarching syndrome of acute kidney diseases and disorders. This condition's incidence highest in low-income and middle-income countries. In the short term, AKI is associated with increased mortality, an increased risk of complications, extended stays in hospital, and high health-care costs. Long-term complications include chronic kidney disease, kidney failure, cardiovascular morbidity, and an increased risk of death. Several strategies are available to prevent and treat AKI in specific clinical contexts. Otherwise, AKI care is primarily supportive, focused on treatment of the underlying cause, prevention of further injury, management of complications, and short-term renal replacement therapy in case of refractory complications. Evidence confirming that AKI subphenotyping is necessary to identify precision-oriented interventions is growing. Long-term follow-up of individuals recovered from AKI is recommended but the most effective models of care remain unclear.

ObjectivesRhythmic gymnastics is an Olympic sport that demands high training volume from early age. We investigated the extent of, and risk factors for, injuries among competitive Norwegian rhythmic gymnasts.MethodsOne hundred and seven of 133 (80.5%) female rhythmic gymnasts (mean age: 14.5 years (SD 1.6), mean body mass index: 18.9 (SD 2.2)) participated. All gymnasts completed a baseline questionnaire and the ‘Triad-Specific Self-Report Questionnaire’. Injuries, illnesses and training hours were recorded prospectively for 15 weeks during preseason using the ‘Oslo Sports Trauma Research Center Questionnaire on Health Problems’ (OSTRC-H2).ResultsResponse rate to OSTRC-H2 was 97%. Mean overuse and acute injury prevalence were 37% (95% CI: 36% to 39%) and 5% (95% CI: 4% to 6%), respectively. Incidence was 4.2 overuse injuries (95% CI: 3.6 to 4.9) and 1.0 acute injuries (95% CI: 0.5 to 1.6) per gymnast per year. Overuse injuries in knees, lower back and hip/groin represented the greatest burdens. Previous injury increased the odds of injury (OR 30.38, (95% CI: 5.04 to 183.25)), while increased age (OR 0.61 per year, (95% CI: 0.39 to 0.97)) and presence of menarche (OR: 0.20, (95% CI: 0.06 to 0.71)) reduced the odds of all injuries and substantial injuries, respectively.ConclusionsOveruse injuries were common among Norwegian rhythmic gymnasts. Younger gymnasts had higher all-injury risk. Gymnasts who were not menstruating had higher substantial injury risk. Injury prevention interventions should start at an early age and focus on preventing knee, lower back and hip/groin injuries.

BackgroundGroin injuries represent a considerable problem in male football. Previous groin-specific prevention programmes have not shown a significant reduction in groin injury rates. An exercise programme using the Copenhagen Adduction exercise increases hip adduction strength, a key risk factor for groin injuries. However, its preventive effect is yet to be tested.AimTo evaluate the effect of a single-exercise approach, based on the Copenhagen Adduction exercise, on the prevalence of groin problems in male football players.Methods35 semiprofessional Norwegian football teams were cluster-randomised into an intervention group (18 teams, 339 players) and a control group (17 teams, 313 players). The intervention group performed an Adductor Strengthening Programme using one exercise, with three progression levels, three times per week during the preseason (6–8 weeks), and once per week during the competitive season (28 weeks). The control group were instructed to train as normal. The prevalence of groin problems was measured weekly in both groups during the competitive season using the Oslo Sports Trauma Research Center Overuse Injury Questionnaire.ResultsThe average prevalence of groin problems during the season was 13.5% (95% CI 12.3% to 14.7%) in the intervention group and 21.3% (95% CI 20.0% to 22.6%) in the control group. The risk of reporting groin problems was 41% lower in the intervention group (OR 0.59, 95% CI 0.40 to 0.86, p=0.008).ConclusionThe simple Adductor Strengthening Programme substantially reduced the self-reported prevalence and risk of groin problems in male football players.Trial registration number ISRCTN98514933.
