Incidence Of Injuries In Athletes Research Articles

Incidence of Injuries in Athletes of Olympic Wrestling

The Olympic wrestling is contact sport and high intensity, with a pause between these thirty second periods and the maximum time to recover from any injury during combat is two minutes [1]. Because it is a contact modality its practice is related to a high incidence of orthopedic injuries.

Injury and Disease in Former Collegiate Athletes

Athletes undergo vigorous training in order to be successful in their sport. They must participate in more than the recommended amount of daily physical activity to reach a high level of competition. High levels of training can lead to high risk of injury in specific sports, which may lead to future disability and potential risk of chronic disease. The purpose of this review was to examine the incidence of injury in athletes in specific sports. There have been several studies that have tried to establish a link between future disease risk and prior athletic participation. Prior injury may play a role in the development of future disease. This review also examined the relationship between specific sports and future chronic disease risk. Results confirm that more research is needed in order to link injuries in early athletics with future chronic disease risk. Risk of osteoarthritis after joint injury in athletic competition is high in each study analyzed. This review may shed light into the risk carried in specific sports for injury, and serve as a starting place for future research into the risk of chronic disease in athletes with prior injuries.

Incidência de lesões em velejadores brasileiros de diferentes níveis técnicos

O primeiro passo para reduzir a incidência de lesões em atletas é avaliar as características dos acometimentos, fornecendo subsídios para a estruturação e aplicação de programas de prevenção. Este estudo teve por objetivo investigar a incidência de lesões em atletas iatismo de diferentes níveis técnicos. A amostra foi composta por 172 velejadores, divididos em três grupos: 89 velejadores iniciantes, participantes da Seletiva do Campeonato Mundial da Classe Optimist (grupo 1); 29 velejadores juvenis participantes, da Copa da Juventude de Vela (grupo 2); e 54 velejadores da elite nacional, participantes da Semana Pré-Olímpica de Vela (grupo 3). Utilizou-se como instrumento de coleta de dados um questionário do tipo misto e os dados foram analisados através da estatística descritiva. Cinco atletas do grupo 1 (5,6%), cinco atletas do grupo 2 (17,2%) e 15 atletas do grupo 3 (27,8%) relataram algum tipo de lesão relacionada com a modalidade. Observou-se maior incidência de lesões na coluna e no joelho e o diagnóstico mais citado foi a lesão muscular, seguida dos cortes, entorses e tendinites. A incidência de lesões no iatismo é baixa se comparada com a de outras modalidades esportivas, apesar da alta demanda física exigida durante as ações sobre o barco. Verificou-se que os atletas profissionais, que possuem maior média de idade e de tempo de prática, foram os mais acometidos por lesões. Em contrapartida, a incidência é menor entre os grupos de crianças e adolescentes. É importante, portanto, que programas de prevenção sejam iniciados desde os primeiros anos de prática, no intuito de reduzir o risco de acometimentos futuros, principalmente de natureza crônica. Com base nas informações acerca do tipo de lesão, sugere-se a inclusão de exercícios de condicionamento específico da musculatura e de compensação nos programas de treinamento, além de sessões de alongamento e relaxamento.

Effects of Fatigue on the Landing Mechanics of the Female Recreation Athlete

0721 Altered neuromuscular control strategies and movement patterns are believed to contribute to the increased incidence of injuries in athletes during landings. These performance differences have been associated with fatigue that has also been identified as a risk factor for non-contact mechanism of injury. PURPOSE: to examine the effects of fatigue on lower extremity kinematic and variables during landing. Methods: Kinematic and kinetic data were collected from 15 female subjects in a series of five landings performed both before and after the performance of a running fatigue protocol. Landings were performed from a .39m height onto a force platform. Ground reaction forces and 3D joint positions, moments, powers, were compared pre and post-fatigue using a series of repeated measures analyses of variance (alpha = 0.05). Results: There was an increase in the maximum knee valgus angle (24.8 vs. 29.3, p = .037) and foot pronation (−12.9 vs. −20.2, p = .000) with fatigue; as well as a decrease in both the hip extensor moment (1.007 vs. .838, p = .000) with fatigue. Relative contributions of each joint relative to power absorption were also altered with the distal to proximal distribution changing to a knee dominant absorption pattern post-fatigue. Conclusion: Potential causes for these changes include changes due to the direct results of fatigue and/or adaptations in strategies to reduce the forces imposed on the lower extremity musculature secondary to fatigue.
