Características de lesões em paratletas da Indonésia antes das Olimpíadas de Tóquio em 2020: um estudo transversal / Injury characteristics of Indonesian paraathletes prior to Tokyo Olympics 2020: a crosssectional study

OBJETIVOS: Esta pesquisa tem como objetivo elucidar as características das lesões em atletas da seleção da Indonésia. MÉTODOS: Os sujeitos deste estudo foram nove atletas (masculino = 5, feminino = 4) com homens em torno da idade de 28 ± 9,13 e mulheres 28 ± 5,66 anos. A abordagem do método é descritiva com uma técnica de estudo transversal usando um questionário sobre histórico de lesões, tipos de lesões, fatores de lesões e gerenciamento de lesões para atletas indonésios que competiram nos Jogos Olímpicos de Tóquio em 2020. A análise de dados é representada em números e porcentagens e o teste exato de Fisher é usado para determinar a relação entre as variáveis. RESULTADOS: Os resultados do estudo relataram que os atletas indonésios sofreram lesões nos membros inferiores (70%), a parte do corpo que frequentemente sofre lesões foi a coxa (28%) e o tipo de lesão que frequentemente sofreu foi entorse / torção. CONCLUSÃO: As características da lesão na categoria sprint (pista) formam um padrão de lesões na coxa, tendão de Aquiles, tornozelo e joelho. Parece não haver correlação entre gênero, frequência de treinamento, proporção de lesões, número de partidas e tipo de aquecimento. A implicação é que o gerenciamento de lesões é necessário antes e durante a competição, considerando a biomecânica, a fisiopatologia e os problemas psicossociais. As estratégias de prevenção de lesões por treinadores e equipes médicas devem levar a uma redução mais significativa de lesões e otimizar a saúde, segurança e bem-estar dos atletas.

BACKGROUND: Sports for people with disabilities and injuries have been the subject of discourse in the professional literature in the fields of traumatology and sports medicine. OBJECTIVE: This research aims to elucidate the injury characteristics of athletes in the Indonesian national team. The subject of this study were nine athletes (male=5, female=4) with males around the age of 28±9.13 and females 28±5.66 years. METHOD: The method approach is descriptive with a crosssectional study technique using a questionnaire about injury history, types of injury, injury factors, and injury management for Indonesian Para Athletics Athletes who have competed in the 2020 Tokyo Olympics. Data analysis is depicted in numbers and percentages and Fisher's exact test is used to determine the relationship between variables. RESULTS: The study results reported that Indonesian athletes suffered injuries of the lower limbs (70%), part of the body that is frequently injured was the thigh (28%) and the type of injury that was often experienced sprain/twist. CONCLUSION: The injury characteristics in the sprint (track) category form a pattern of injuries to the thigh, Achilles tendon, ankle, and knee. There appears to be no correlation between gender, training frequency, injury share, match number, and warm-up type. The implication is that injury management is necessary before and during competition by considering biomechanics, pathophysiology, and psychosocial problems. Injury prevention strategies by coaches and medical teams should lead to more significant injury r

A two-age-classes dengue transmission model.

In this paper, we discuss a two-age-classes dengue transmission model with vaccination. The reason to divide the human population into two age classes is for practical purpose, as vaccination is usually concentrated in one age class. We assume that a constant rate of individuals in the child-class is vaccinated. We analyze a threshold number which is equivalent to the basic reproduction number. If there is an undeliberate vaccination to infectious children, which worsens their condition as the time span of being infectious increases, then paradoxically, vaccination can be counter productive. The paradox, stating that vaccination makes the basic reproduction number even bigger, can occur if the worsening effect is greater than a certain threshold, a function of the human demographic and epidemiological parameters, which is independent of the level of vaccination. However, if the worsening effect is to increase virulence so that one will develop symptoms, then the vaccination is always productive. In both situations, screening should take place before vaccination. In general, the presence of class division has obscured the known rule of thumb for vaccination.
