Referring to judo's sports injuries in São Paulo State Championship

Objective. - In a pioneer way, we investigated the morbidity of sports injuries referred by judo athletes from São Paulo State Championship.Material and methods. - Data collection from 93 senior judokas in State of São Paulo Judo Championship, through Referred Morbidity Inquiry about last year.Results. - One hundred and ten events were registered with a distribution frequency gradient of sprain > contusion > strain > ligament injury > partial and total dislocation. The most injured body areas were: knee (26.3%), shoulder (21.8%), fingers (17.3%), and ankle (10.0%). The most risky situation was when the athlete was training (standing, applying a blow) and it can be explained by the frequent and unprepared exposition of the athletes. Yearly lesion rate was 1.18 injuries per athlete/year.Conclusion. - Sprains constitute the most common judo injury, and athletes are more susceptible when they apply blows; discussion about the direction that the prevention should be applied remains opened.

Sports injuries among adolescent basketball players according to position on the court

Background: The participation of children and adolescents in sports, including basketball, is becoming increasingly common, and this increased involvement raises concerns about the potential risk of sports injuries. Objective. To analyze the occurrence of sports injuries among young basketball players according to their position on the court and to associate these injuries with risk factors. Method. A retrospective, epidemiological study. A sample consisting of 204 basketball players with a mean age of 14.33 ± 1.19 years participated in the study. The players were interviewed using a reported condition questionnaire containing anthropometric and training data as well as information on injuries during the previous 12 months. Results: The frequency of injury was highest among the shooting guards (47.8%), followed by the centers (34.8%) and point guards (17.4%). Among the 204 participants, 40 players reported a total of 46 injuries, representing 0.22 injuries per participant and 1.15 injuries per injured participant. For the shooting guards and centers, statistically significant differences between injured and non-injured players were found related to age, weight, height, length of time in training and number of weekly practice hours (p < 0.05). For point guards, a statistically significant difference between injured and non-injured players was found based on weight alone (p < 0.05). Conclusion: The occurrence of injuries among basketball players was low. Injuries were associated with both intrinsic and extrinsic factors among shooting guards and centers, whereas injuries were only associated with weight among point guards. © 2013 Vanderlei et al; licensee BioMed Central Ltd.

Applications of Infrared Thermography as innovative technological solution in sports injuries

Infrared thermography IR is a technique, which allows us to get rapidly and non-invasive thermal images from objects or human beings. (Barnes, 1967). In Medicine, its usefulness as diagnosis tool was accepted decades ago (BenEliyahu, 1990), but other techniques with a higher efficiency -such as magnetic resonance or x-rays- ousted it. Nevertheless, the technological improvements on thermographic cameras and new studies on sport injuries are reinforcing new applications (Ring, 2006)

Stretch Injuries of Skeletal Muscles: Experimental Study in Rats' Soleus Muscle

The study aimed to verify the physiological injury behavior by stretching the soleus muscle of rats, using a noninvasive experimental model. Twenty-four rats were used and divided into three groups of eight animals: control group (A), group that performed tetanus followed by electrical stimulation and a sudden dorsiflexion of the left paw performed by a device equipped with a mechanism of muscle soleus rapid stretching (B); and a group that only received the tetanus (C). Three days later, the animals were killed, and the soleus muscle was resected and divided into three segments. Morphological changes indicative of muscle damage appeared in all three segments of group B. In a lesser degree, similar changes were also detected in muscles subjected to only tetanus. This model was effective; reproducing an injury similar to what occurs in human sports injuries.

Sports after Busy Work: Work-Related Cognitive Failure Corresponds to Risk Bearing Behaviors and Athletic Injury

Although employees are encouraged to take exercise after work to keep physically fit, they should not suffer injury. Some sports injuries that occur after work appear to be work-related and preventable. This study investigated whether cognitive failure mediates the influence of mental work demands and conscientiousness on risk-taking and risky and unaware behaviour during after-work sports activities. Participants were 129 employees (36% female) who regularly took part in team sports after work. A structural equation model showed that work-related cognitive failure significantly mediated the influence of mental work demands on risky behaviour during sports (p < .05) and also mediated the directional link between conscientiousness and risky behaviour during sports (p < .05). A path from risky behaviour during sports to sports injuries in the last four weeks was also significant (p < .05). Performance constraints, time pressure, and task uncertainty are likely to increase cognitive load and thereby boost cognitive failures both during work and sports activities after work. Some sports injuries after work could be prevented by addressing the issue of work redesign.

Observational research on golf-related injuries

The determination of aetiological factors in sports injuries is challenging. Recently, investigators have devoted significant attention to this topic. A reasonable amount of studies provides information on the occurrence, aetiology, and severity of golf-related injuries. However, gaps of evidence still limit the understanding of the injury problem in golf and the comparability of epidemiological findings. Observational studies using surveys and medical records were reviewed. Surveys are suited to find precise occurrence patterns of golf-related injuries, but fail to adequately ascertain the levels of exposure and aetiological factors. Due to the proximity to the injury event, medical records are able to clearly identify the aetiology and severity of golf-related injuries. While reviewing observational studies using surveys a comment was provided on the methodological quality and risk of bias. Overall, these studies seem to be disturbed on their ability to produce generalizations and comparison of study findings. With the information obtained from reviewing observational studies and the collaboration of a panel of internationally recognised experts on golf science and sports injury research, a web-based bilingual questionnaire was developed and tested for one of the provided languages. The bilingual nature of the questionnaire is also expected to facilitate the acceptance of the scientific community and enable the translation to different languages. A standardised questionnaire applied in different cultural contexts is expected to help and further improve the comparability of epidemiological findings. The questionnaire was proficient in capturing information on golf-related injuries and participation habits of golfers. While using a wider outcome definition focusing on any type of physical complaints, episodes of injury could be recognized despite onset and level of severity. Questions on the need for medical attention, time loss, and impact on performance also enabled additional categorisation of severity.

Should athletes return to sport after applying Ice? A systematic review of the effect of local 3 cooling on functional performance

Applying ice or other forms of topical cooling is a popular method of treating sports injuries. It is commonplace for athletes to return to competitive activity, shortly or immediately after the application of a cold treatment. In this article, we examine the effect of local tissue cooling on outcomes relating to functional performance and to discuss their relevance to the sporting environment. A computerized literature search, citation tracking and hand search was performed up to April, 2011. Eligible studies were trials involving healthy human participants, describing the effects of cooling on outcomes relating to functional performance. Two reviewers independently assessed the validity of included trials and calculated effect sizes. Thirty five trials met the inclusion criteria; all had a high risk of bias. The mean sample size was 19. Meta-analyses were not undertaken due to clinical heterogeneity. The majority of studies used cooling durations >20 minutes. Strength (peak torque/force) was reported by 25 studies with approximately 75% recording a decrease in strength immediately following cooling. There was evidence from six studies that cooling adversely affected speed, power and agility-based running tasks; two studies found this was negated with a short rewarming period. There was conflicting evidence on the effect of cooling on isolated muscular endurance. A small number of studies found that cooling decreased upper limb dexterity and accuracy. The current evidence base suggests that athletes will probably be at a performance disadvantage if they return to activity immediately after cooling. This is based on cooling for longer than 20 minutes, which may exceed the durations employed in some sporting environments. In addition, some of the reported changes were clinically small and may only be relevant in elite sport. Until better evidence is available, practitioners should use short cooling applications and/or undertake a progressive warm up prior to returning to play.

Psychological predictors of injury in elite athletes

The Queensland Academy of Sport (QAS) supports over 600 high-level athletes across 20 sports. Given the high cost of injuries (e.g., time out of sport and consequent detraining, expense of rehabilitation, adverse social and economic effects), comprehensive injury management and prevention has become a priority for the QAS. Considering the potential for developing cost-effective, preventative programs, knowledge gained by examination of psychological screening predictors of injury may also prove beneficial for the broader sports medicine community. Aims were to: Objectively summarise existing injury characteristics, including the creation of population-specific norms for scholarship holders at the QAS. Assess relationships between injuries, specific medical factors (e.g., asthma, back pain) and psychological risk factors including life stress, mood, previous psychological diagnoses and disordered eating behaviour over a three-year period. Evaluate the effectiveness of the psychological component of the QAS Health Screening Questionnaire.

A Eficácia do Programa Fifa 11+ na Prevenção de Lesões em Atletas de Futebol Sub18

Introdução: No futebol, as lesões são da mais fulcral importância pelo que a sua prevenção se revela de extrema pertinência. A FIFA criou o FIFA 11+, um programa de prevenção de lesões, que revelou resultados positivos em equipas jovens tanto femininas como masculinas. No entanto, em Portugal, os resultados da sua implementação são escassos, principalmente em camadas jovens. Objetivo: Estudar a eficácia do programa FIFA 11+ na prevenção de lesões em atletas de futebol – sub 18. Métodos: O presente estudo quasi experimental teve como amostra uma equipa de 24 atletas, divididos voluntariamente em 2 grupos: o grupo experimental (GE) (n=12), e o grupo controlo (GC) (n= 12). Ambos os grupos realizaram os treinos normais sendo o grupo experimental sujeito adicionalmente ao programa FIFA 11+ duas vezes por semana, durante 12 semanas. Foi utilizado ainda o Orchard Sports Injury Classification System (OSICS-10) como sistema de classificação de lesões, sendo estas divididas em graves, moderadas, leves e mínimas. O teste Mann-Whitney foi utilizado para a comparação entre grupos, e o teste de Wilcoxon para a comparação intra grupo. Resultados: Quando comparados o GE com o GC em M0 não se observaram diferenças estatisticamente significativas (p=0.065), no número de lesões entre os grupos. O mesmo se verificou após a implementação do programa FIFA 11+ (p=1,000). Na comparação intra-grupo de M0 e M1 o grupo controlo não apresentou diferenças estatisticamente significativas (p=0,317) enquanto que no grupo experimental se observou que existiam significativamente menos lesões após a implementação do programa. (p=0,025). Conclusão: O programa FIFA 11+ parece ser indicado para a prevenção e diminuição de lesões desportivas em jogadores amadores de equipas sub-18, quando aplicado duas vezes por semana. Apesar disso, para eleger o programa como uma ferramenta de eleição na promoção da saúde, mais estudos são sugeridos utilizando uma amostra maior e se possível num período superior.

Exploração de fatores de risco para lesões no atletismo de alta performance

Os fatores de risco para instalação de lesões do esporte têm sido pesquisados no sentido de facilitar o entendimento sobre o assunto. Contudo, para altos níveis de performance, nos eventos de pista e campo do atletismo, são escassos os documentos que abordam o tema. Assim, a partir da possibilidade de reunir informações sobre a condição descrita, objetivou-se com o presente estudo a exploração de fatores de risco para lesões desportivas no atletismo, a partir de inquérito aplicado a atletas da elite mundial da modalidade. A população foi composta por 60 homens e 60 mulheres alocados em grupos conforme a especificidade de sua modalidade (velocidade, resistência, arremessos e saltos). Realizou-se entrevista utilizando-se de inquérito de morbidade referida, abordando questões sobre variáveis antropométricas e de treinamento, assim como lesões. Utilizou-se a técnica da análise de variância paramétrica para as variáveis antropométricas (idade, peso, estatura) e da técnica da análise de variância não paramétrica em relação às variáveis de treinamento (anos de treinamento e horas semanais). Para associação entre momento de lesão e especialidades, utilizou-se do teste de Goodman em nível de 5% de significância. Os resultados mostraram que houve elevada freqüência de lesões na modalidade em ambos os sexos. As taxas de lesão por atleta entrevistado foram de 0,92 (velocidade), 1,08 (resistência), 1,22 (saltos) e 1,20 (arremessos). Não houve diferença estatisticamente significante para as variáveis antropométricas e de treinamento em relação às provas, com exceção dos saltadores, que apresentaram diferenças para estatura e tempo de treinamento; nesse caso, os acometidos são mais altos ou praticam atletismo há menos tempo (P < 0,05). Concluiu-se que, para população estudada, o risco de lesão é acentuado, mas sem relação entre variáveis e presença de agravos, salvo para especialistas em provas de saltos, que apresentaram estatura e tempo de treinamento como fatores predisponentes à lesão.
