跳跃任务下消防员下肢肌肉激活分析与损伤风险研究
Analysis of lower limb muscle activation and injury risk in firefighters under jumping tasks
摘要
Abstract
To explore the relationship between muscle synergy patterns and firefighters'injury risk,we constructed a risk assess-ment model for injuries,analyzed the muscle patterns of the lower limbs of firefighters during jumping,and evaluated the risk of injury.Firstly,10 firefighters were recruited and divided into injured and non-injured groups.The injury status of the firefighters was then re-corded one year after the experiment.Subsequently,muscle synergy characteristics were analyzed via non-negative matrix factorization and least squares to develop the injury risk assessment model.The results showed that 4 and 3 synergy patterns in the injured group and non-injured group respectively,which proved the phenomenon of pattern decomposition.Differences in force-generating characteristics between the two groups were identified based on the temporal feature H vector.The risk assessment model(R2＝0.6899,P＝0.0006)indicated that firefighters with fewer muscle synergy patterns had a lower risk of injury.The result indicates that enhancing muscle strength can reduce the risk of training injuries.关键词
