Quality of reporting of randomised controlled trials – an analysis of the world congress of sports injury prevention in 2005 and 2008
Authors: Knobloch K , Yoon U 
Published: March 2011

BackgroundReporting quality of clinical trials has been addressed by the CONSORT group for randomised controlled trials (RCTs) first in 1996 with updates in 2001 and 2010.ObjectiveWe hypothesised that the quality of reporting in sports injury prevention abstracts has increased from 2005 to 2008 as did the amount of RCTs at the 1st versus 2nd World Congress of Sports Injury Prevention in Oslo vesus Tromsø.DesignAnalysis of the published abstracts of the 2005 and 2008 World Conference on Sports Injury Prevention, two independent analysts.Setting154 abstracts from the 2005 and 186 abstracts from 2008 World Conferences were analysed.Main outcome measuresEvidence-based study design, scores of 17 CONSORT criteria for RCT.ResultsRCTs were published in 9.1% in 2005 versus 10.2% in 2008 (p=0.727) of all published abstracts. Improvement in reporting was evident for RCTs in the CONSORT score 5.8±0.9 versus 8.6±2.9 (p=0.001, CI −4.29 to −1.43). Detailed description of main outcomes demonstrated the most significant improvement in reporting in the abstracts of RCTs (0% vs 57.9%, p<0.001). Study design mentioned in the title, trial design, participants, blinding, number analysed, outcome and funding tended to but did not improve significantly in the reporting RCTs in conference abstracts. No improvement at all over the 3 years was noted for reporting quality of the title randomised, authors, intervention, objectives/hypothesis, randomisation, numbers randomised, recruitment, and number analysed, harms and trial registration.ConclusionWhile the percentage of published RCTs in abstracts at the World Congress of Sports Injury Prevention remained mainly unchanged, improvement in reporting of abstracts was evident from 2005 to 2008 determined by CONSORT criteria. Further substantial and comprehensive use of the recently updated CONSORT 2010 criteria might further increase the quality of reporting of sports injury conference RCTs in the future and should be endorsed.

Authors: Lerch C , Cordes M , Baumeister J 
Published: March 2011

IntroductionThere is growing evidence on the higher vulnerability of the knee in young female soccer players. In adult female soccer populations injury prevention programs had demonstrated positive effects on injury incidence. Beside this functional component it is not only common sense but neuroscientific knowledge from motor learning studies that exercises which include a playful and joyful character are more suitable for young people and may support an enduring effect of prevention.PurposeThe aim of the study was (1) to assess the effectiveness of injury prevention programs in female youth soccer and on the other hand to see (2) if prevention programs have been adapted to this specific adolescent population.MethodsA systematic literature search was performed in relevant databases (PubMed, PEDro, BioMedLib) to identify injury prevention programs. Randomised controlled trials comparing the effects in female youth soccer players (<18) on the incidence of injuries were screened by two independent reviewers.ResultsFive studies were included, reporting investigations of injury prevention programs in female youth soccer. Four studies demonstrated an effect on the incidence of different injuries. All programs consist of multi-component exercises categorised by the authors as related to strength, flexibility, plyometrics, agility and balance. In four studies a functional adult prevention program was applied to the young soccer players whereas one study adopted the program to adolescents in terms of the higher variability of exercises to avoid boredom.ConclusionOn the basis of the results of five high-quality studies, this review help to demonstrate the effectiveness of injury prevention programs in female youth soccer players. However, the number of studies investigating such intervention programs should be increased. To strengthen the enduring effect of injury prevention the development of joyful and playful programs especially for female youth soccer players may be an option to construct successful intervention programs.This project was supported by the Youth Soccer Foundation (http://www.stiftung-jugendfussball.de).

BackgroundFootball in Kenya is not only a leisure activity, but also a tool for community and individual development. Studies on injury risk in female youth football players in Africa are limited.ObjectiveTo analyze the incidence, characteristics and circumstances of injuries.DesignProspective cohort study.SettingA two-day female youth football tournament in Nairobi, Kenya.ParticipantsA total of 938 players from 69 teams participated in the tournament. All players were included in the study.Main outcome measurementsAny physical complaints incurred by a player during a match were registered by trained Kenyan injury reporters. The injury reporters were supported by four physiotherapists and two doctors. All complaints were registered regardless of their consequence.ResultsA total of 123 injuries were reported from 106 matches. The incidence of all injuries was 93.3 injuries/1000 h (95% CI 76.8 to 109.8). Most injuries allowed the players to continue to play (n=98; 81%). Players under the age of 13 (RR=2.16; 95% CI 1.34 to 3.47; p=0.002) and 16 (RR=2.17; 95% CI 1.35 to 3.50; p=0.002) had an increased risk of injury compared to those over 16. Eight injuries (7%; 6.1 injuries/1000 h; 95% CI 1.9 to 10.3) were expected to result in absence from play of 1–7 days. The injuries most commonly involved the lower limb (n=100; 82%). A contusion to the ankle (n=15; 12%) and foot/toe (n=15; 12%) were the most common specific injury types. Most acute injuries (89 of 113, 79%) were caused by player contact.ConclusionThe incidence of injuries among female youth football players in a national tournament in Kenya was high, with players under the age of 13 and 16 at greatest risk. However, most injuries were minor and did not prevent continued participation in the tournament. This can be seen as positive, as football plays a vital role in individual and community development in Kenya.

BackgroundIt is not unusual for athletes to decide to participate in important competitions, despite an ongoing disability or injury.ObjectiveEvaluate the degree of confidence exhibited by injured athletes with regards to their participation in a major competition, and to profile the musculoskeletal injuries.DesignA cross-sectional survey was conducted with the athletes of the Brazilian delegation participating in the IX South American Games, and 2nd Lusophony Games who sought care from the Brazilian team's medical department with various musculoskeletal complaints.SettingA group of elite athletes prior to the start of an official competition.ParticipantsOf the 697 participants in the Brazilian delegation to the IX South American Games (Medellin, 2010) and 2nd Lusophony Games (Lisbon, 2009), 98 athletes (14.6%) sought care from the Brazilian team's medical department with various musculoskeletal complaints, even before commencing participation in the competition.Main outcome measurementsDegree of confidence exhibited by injured athletes and the profile of the musculoskeletal injuries.ResultsRegarding the onset of injury, the 98 (14.6% of the 697 total participants) injured athletes who sought care from the medical staff, 57.1% of the athletes had been injured for longer than two months (n=56). Approximately half (n=44, 44.9%) reported that the injury was recurrent. The most frequently occurring injury was tendinopathy (n=33, 27.5%), and the most frequent location of injury was the knee (n=20, 18%).ConclusionsWe could observe that many athletes participating in a major competition even with existing musculoskeletal complaints were worried about their injuries affecting their well-being and performance. The majority of these athletes had been injured for longer than two months. Approximately half of them reported that the injury was recurrent. The most frequently occurring lesion was tendinopathy, and the most frequent location of injury was the knee.

BackgroundKnee instability after Anterior Cruciate Ligament (ACL) reconstructive surgery may lead to osteoarthritis.ObjectiveTo complete current evaluation of anterior knee laxity.DesignCross-sectional pilot study.SettingPhysical therapy unit of the Clinique d'Eich, Centre Hospitalier de Luxembourg.Patients14 patients were examined 197±25 days following arthroscopic ACL reconstructive surgery (11 men and 3 women, age: 28±9 years) using the GNRB, a new knee arthrometer measuring anterior tibial displacement (ATD) when applying a standardised, progressive anterior tibial force. Inclusion criteria were: isolated ACL rupture; no prior injury in the controlateral knee.InterventionsBoth knees were tested using three trials with a progressive force up to 200 N, starting with the controlateral leg. The average ATD-force curve of trials 2 and 3 were used for further calculations.Main outcomesATD at 134 and 200 N, and new variables: primary energy dissipation (PED: area under the ATD-force curve from 0 to 100 N), secondary energy dissipation (SED: area under the ATD-force curve from 100 to 200 N), primary compliance (PC: slope of the ATD-force curve between 30 and 50 N) and secondary compliance (SC: slope of the ATD-force curve between 100 and 200 N) were used as indicators of knee laxity.ResultsThe results found for the operated and the controlateral knee, respectively, were: ATD at 134 N=5.6±1.6 and 4.0±0.9 mm (difference: 42%); ATD at 200 N=7.2±1.8 and 5.3±1.0 mm (difference: 34%); PED=230±80 and 146±46 N/mm; SED=622±167 and 445±96 N/mm (difference of area between both curves at 134 N: 52%, at 200 N: 44%); PC=63±22 and 40±13 μm/N; SC=25±6 and 22±4 μm/N. Results were significantly different (p<0.05) for all indicators except SC (Student t-test).ConclusionAnterior knee joint laxity 5 to 10 months after ACL reconstructive surgery remains greater than the non-injured contralateral knee. A complete evaluation of anterior knee laxity could help the prognostic of osteoarthritis after ACL reconstructive surgery.

The medical screening of young athletes assures the early recognition of health problems and properly timed restriction from sports activities provides the safety of sporting. In 2009 the Estonian Health Insurance Fund prevention project ‘The medical screening of young athletes for prevention of sports-related health risks’ was started.The aim of the study was to establish the most common health problems occurring in young athletes, to determine the amount of athletes disqualified from participation in trainings and competition due to health problems, and to explore the main reasons for disqualification.Young athletes (n=1479) in age range from seven to 19 years (mean age 13±3 years, 70% boys), involved in 54 different sports, were screened during eight months period in 2009 in Sports Medicine and Rehabilitation Clinic of Tartu University Hospital. The International Statistical Classification of Diseases and Related Health Problems (ICD-10) was used for classification of health problems.In 830 (56%) of young athletes diseases or related health problems were established. Most common organ systems involved were musculoskeletal (posture disturbances, lower extremity enthesopathies, and back problems), cardiovascular (cardiac conduction disorders, arrhythmias, and hypertension), and respiratory system (chronic tonsillitis and asthma) – 41%, 30% and 11% respectively. The health problems occurred more often in age range 13 to 17 years. Track and field, football and volleyball were the sports where athletes had more health problems. The participation restrictions were applied in 171 (11.6%) young athletes (68% boys), in one case the athlete was disqualified from certain sport. Cardiovascular (46%), musculoskeletal (29%), and respiratory (12%) conditions were most frequent reasons for participation restrictions. Although musculoskeletal symptoms and conditions are more common in young athletes, the conditions related to cardiovascular system led more often to participation restriction.

Authors: Owoeye O B A 
Published: March 2011

BackgroundThere is a dearth of information on the epidemiology of sports injuries in Nigeria.ObjectiveThe study was aimed at documenting sports injuries sustained by Lagos state athletes during the 16th National Sports Festival and providing information on treatments offered to injured athletes.DesignProspective descriptive study.SettingThe study was carried out at the Amadu Bello Stadium Complex, sporting arena of the Murtala Square and the team Lagos mini clinic.Participants132 accredited Lagos state athletes who at one point in time during the games required treatment from any of the members of the medical team.Main outcome measurementsDemographic data of athletes, type of injuries, body parts injured and treatment modalities used were recorded on pre-designed injury report forms and analysed using descriptive statistics.ResultsA total of 140 sports injuries were recorded with an approximate male to female ratio of 2:1 and age ranging from 15 to 38 years. Most of the injuries reported by the athletes were ‘minor’ injuries. Muscle strain was the most common type of injury (31.4%) followed by ligament sprains (22.9%). The lower extremities were the most injured body region accounting for 50% of all injuries. Over 60% of injuries presented by the athletes were from basketball, cricket, hockey, rugby and baseball. Cryotherapy was the most frequently used treatment modality, followed by bandaging and massage with anti-inflammatory gels.ConclusionEstablishing injury prevention programmes directed at the lower extremities may help reduce the risk of injuries to the lower extremities. It is recommended that cryotherapy should be made abundantly available to the medical team preferably in forms of portable cold sprays for easy transportation and application during the games. This data provides information that will be useful to both state and federal medical teams in preparing for future games.

Authors: de Barros M Paes , Soares C O , Pereira B , Bechara E J H , Silveira L R , Curi R , Souza-Junior T P 
Published: March 2011

BackgroundA plethora of data revealed that reactive oxygen species (ROS) are normally produced during/after endurance or resistance exercise. Drastic drops in performance, precocious fatigue and injury risk are putative outcomes of the ROS-mediated biochemical changes. On the other hand, adequate ROS production is essential to provide the desired physiological adaptations of training and to avoid related immune depression.ObjectiveThis work aims to test plasma biomarkers of oxidative stress for an accurate evaluation of exhaustion in athletes.DesignSubjects were prospectively randomised evaluated.SettingMale cyclists of Brazilian college league (university games) were selected.ParticipantsSubjects (n=20) had no history of smoking, alcohol abuse, or systemic disease.InterventionsA Wingate Test was carried out using a Cybex cycle ergometer with increasing loads up to 10% BW (preheat procedure for 5 min). Athletes were strongly encouraged during the test for maximum effort achievement.Main outcome measurementsBlood samples (5 ml) were collected before and after the Wingate test, using EDTA-containing Vaccuntainer kits. Total iron, haemoglobin, uric acid, Ferric-reducing activity (FRAP), and malondialdehyde (biomarker of lipid oxidation) were measured in plasma.ResultsPlasma iron and FRAP levels varied consistently when total amounts released from time zero to 60 min after the Wingate test were evaluated (R=0.939). Remarkably, uric acid was identified as one of the major contributors for FRAP capacity, thus, restricting iron ions participation as catalysts for ROS overproduction during exercise. Lower indexes of lipid oxidation were reported under these circumstances.ConclusionThe pool of plasma biomarkers – total iron, FRAP, uric acid and malondialdehyde – are good candidates for an efficient evaluation of oxidative stress related to exhaustion. Further investigations are necessary to precise how responsive those parameters are at different exercise intensities.Financial support: FAPESP, CAPES & CNPq (Brazil); BioReal AB/Fuji Health Sciences (Sweden/Japan).

Published: March 2011

BackgroundTeam handball has a rich tradition and interest among Icelanders. No studies have been published on the incidence and nature of injuries in Icelandic team handball.ObjectiveTo examine and document the incidence, nature and severity of injuries in male team handball.DesignProspective cohort study. The teams were followed for 9 months. Injuries were recorded by the players under supervision from their team physiotherapists, coaches and delegates on a special form. Coaches recorded training exposure.SettingIcelandic elite male team handball.ParticipantsPlayers from all (eight) premiership and six best (of eight) second division teams were invited to participate. The selection was based on the 2006–2007 league position. 159 players from seven premiership and 4 s division teams entered the study. 109 players from four premiership and 2 s division teams finished it.Main outcome of measurement(1) Incidence and severity of acute and overuse injuries. (2) Variation between teams and playing positions. (3) Use of braces and tape.Results86 injuries were recorded, 53 (61.6%) acute, and 33 (38.4%) overuse injuries. The injury incidence was 15.0 injuries per 1000 player hours during games and 2.2 injuries per 1000 player hours during training. Acute injuries were most common in knees (26.4%). Overuse injuries were most frequent in low back/sacrum/pelvic region (33.3%). No difference was in incidence of injuries between teams. Back court players were most frequent injured, goalkeepers least. 22.4% of the players used ankle braces during games and most training sessions. 28.2% used tape on fingers.ConclusionThe total injury incidence is similar than in previous, comparable studies. However, higher rate of overuse injuries in low back/sacrum/pelvic region raise questions about training methods and preparation for the Icelandic team handball players.

Published: March 2011

BackgroundThe indoor soccer is a sport that presents contact situations, acceleration and deceleration, combined with accurate raisins and rapid change of direction. Despite the high incidences, the literature is scarce on this modality.ObjectivesTo analyze the injuries profile in indoor soccer athletes from various categories and find the relationship between the frequency of injuries and the volume of games in a season.DesignThis is an observational study, transversal, about the injuries in the 2009 season.SettingAthletes from seven competitive categories under 12, 13, 14, 15, 17, 20 years and adult of a sport club in Belo Horizonte, Minas Gerais, Brazil.Patients83 athletes who required physical treatment.InterventionsThe physiotherapist report all injuries that occurred during the season, which required physical therapy treatment.Mains outcome measurementThe report describe: category, situation of contact or non-contact, if occurred during practice, games or other and the time lost, for a descriptive analysis. The number of games by each category was monitored for analyze the correlation between the injuries frequency with the volume of games by the Pearson test.ResultsThe athletes had 174 injuries which required physical therapy. The average of injuries by athlete was 2.1. The category with greater incidence was the adult; there was a tendency of higher age present a greater frequency of injuries. The majority of injuries occurred in situations of non contact and during training. The muscle injuries were mainly non contact, while contact had predominance of bone and ligament injuries. The Pearson's test indicated statistically significant correlation (R=0.79/p=0.034) between incidence of injuries and the number of games carried out.ConclusionThis profile brings important data for the development of preventive program, to design more specific interventions. Further epidemiological are necessary, mainly for the futsal by virtue of the scarce literature.

Published: March 2011

BackgroundRisk for injury in professional soccer is one of the largest in sports. Next to negative aspects for players' health, in professional soccer the absence of players due to injury leads to high costs. Therefore it is important to gain knowledge on injury risk factors within this specific athletic population to draw up measures that may prevent injuries.ObjectiveTo systematically review intrinsic and extrinsic risk factors which are related to injuries in male professional soccer players.DesignA computerised literature search was carried out in Medline, Embase, SportDiscus and PsycInfo to search for relevant original studies. A study was included if: (1) it contained data of professional, adult, male soccer players; (2) it concerned a prospective or retrospective cohort study covering at least half a season; (3) it addressed data of at least one team; (4) it assessed risk factors for injuries. All relevant studies were assessed for quality.ResultsIn total 313 articles were found, of which 14 were identified as being relevant and of sufficient methodological quality. In total 14 potential intrinsic and nine potential extrinsic risk factors were investigated in the included studies. From these, previous injury, preseason strength imbalances, decreased muscle flexibility and a preseason ultrasonic abnormality in the Achilles tendon were reported in the literature as intrinsic risk factors for injury. With regard to extrinsic risk factors artificial turf, match result, and time of the season were associated with injury occurrence.ConclusionTo date, aetiological studies in professional soccer have mainly charted player characteristics, for example, age, playing position, strength, and ankle stability. According to the literature 23 potential risk factors have been investigated, and only seven have been associated with the occurrence of injury. Future research should further explore modifiable extrinsic risk factors, and translate ascertained factors into practical preventive efforts.
