Tóm tắt

Firefighters carrying self-contained breathing apparatus (SCBA) during training or firefighting may reduce gait stability and increase the risk of injury. Twelve firefighters participated in treadmill gait experiments while carrying SCBA. Multiscale entropy (MSE) and fused pressure region amplitude ratios were used to assess gait stability and pressure distribution. Results showed that as speed increased from 4.5 km/h to 6 km/h, pressure amplitude decreased by 14.65% in the forefoot region and increased by 14.12% in the hindfoot region. MSE showed increased gait complexity at 6 km/h and increased stability at 4.5 km/h. These findings provide insights for potential boot optimization.
