A sĂndrome da banda da iliotibial Ă© uma das lesĂ”es mais comuns entre corredoras, especialmente em atletas de trail running, sendo influenciada por fatores biomecĂąnicos como a carga mecĂąnica e os padrĂ”es de movimento durante a corrida. O objetivo deste trabalho foi analisar a relação entre a frequĂȘncia da passada e dos fatores de risco biomecĂąnicos, nomeadamente a carga cumulativa e os Ăąngulos intersegmentares da anca e joelho. Participaram sete atletas femininas de trail running, que realizaram testes de corrida num terreno irregular com sensores inerciais e palmilhas de pressĂŁo para recolha de dados cinemĂĄticos e dinĂąmicos. Os resultados nĂŁo encontraram correlação significativa entre a frequĂȘncia da passada e a carga cumulativa, nem com os Ăąngulos articulares analisados. A literatura sugere que uma menor frequĂȘncia da passada pode aumentar o risco de lesĂ”es devido Ă maior carga cumulativa e alteraçÔes biomecĂąnicas, mas os resultados deste trabalho nĂŁo comprovam essa hipĂłtese. A limitação da amostra e a variabilidade do terreno podem ter influenciado os dados
Iliotibial band syndrome is one of the most common injuries among female runners, particularly in trail running athletes, and is influenced by biomechanical factors, including mechanical load and movement patterns during running. The aim of this study was to analyze the relationship between stride frequency and biomechanical risk factors, namely cumulative load and intersegmental angles of the hip and knee. Seven female athletes participated, performing running tests on uneven terrain with inertial sensors and pressure insoles to collect kinematic and dynamic data. The results did not find a significant correlation between stride frequency and cumulative load, nor with the analyzed joint angles. The literature suggests that a lower stride frequency may increase the risk of injuries due to higher cumulative load and biomechanical alterations, but the results of this study do not support that hypothesis. The sample size limitation and terrain variability may have influenced the data
