Resumo
As exigências físicas impostas aos bailarinos na sua prática artística, representam um risco significativo de lesão com taxas de incidência semelhantes aquelas observadas em atletas no mesmo nível de desempenho. A força muscular tem sido sugerida como um potencial elemento preventivo a considerar contra as lesões. No entanto, a natureza dessa relação ainda não é clara. O objetivo desta tese foi o de examinar a natureza dessa relação no cenário pré-profissional. Uma revisão sistemática da literatura (Estudo I) foi realizada para determinar o estado do conhecimento. Várias lacunas foram encontradas no que dizia respeito à epidemiologia das lesões na dança. Pela necessidade das mesmas serem preenchidas, um estudo epidemiológico (Estudo II) foi realizado com o objetivo de descrever os padrões de lesão na nossa população. Depois de identificar os saltos como a ação motora mais associada às lesões, o Estudo III teve como objetivo examinar a relação entre as características da potência dos membros inferiores através do salto vertical e o histórico das lesões. Não foram encontradas diferenças entre bailarinos com e sem história de lesão, no que diz respeito à potência dos membros inferiores avaliada através do salto vertical. Após uma análise detalhada dos resultados obtidos ao longo do curso da investigação, concluímos preliminarmente, que o papel da força muscular na propensão para as lesões pode estar mais relacionado com o processo de produção de força do que com o produto final observado. Os bailarinos mais fortes também sofrem lesões.
The physical demands placed on dancers put them at a significant risk for injury, with similar rates as the ones sustained by athletes in sports at the same level of performance. Muscle strength has been suggested to play a preventive role against injury in dancers. Nevertheless, the nature of that relation is still unclear. The purpose of this thesis was therefore to examine the nature of the relation between muscular strength and injuries in the pre-professional setting. A systematic review of literature (Study I) was performed to determine the state of knowledge. Several gaps were found that needed to be bridged for advancing. The major limitations found concerned epidemiological data on injury surveillance. An epidemiological study (Study II) was conducted with the goal of describing the injury patterns within our population. After identifying jumps as the motor action mostly associated with injuries, Study III aimed to examine the relationship between lower extremity vertical jump power features and injury history. No differences were found between dancers with and without injury history with concern to vertical jump power. After detailed analysis of the results obtained along the course of the investigation, we preliminary conclude that the role of muscular strength in injury proneness may more likely be related with the strength production process than with the final product. Stronger dancers do get injured too.
