Abstract：
BACKGROUND: Inclined walking is associated with multiple musculoskeletal benefits and is considered a therapeutic exercise. Various patterns of increased and decreased muscle activation with inclined surfaces have been observed in normal muscles, with more focus on the proximal lower limb musculature.
OBJECTIVE: The aim of this study was to assess the differences in electromyographic activation of gastrocnemius, soleus, and tibialis anterior at various inclined surfaces during gait.
METHODS: Fourteen healthy male participants aged between 17-30 years walked at a self-selected speed at motor driven treadmill on 0, 2 and 4 degrees of inclination. EMG activity of the muscles was recorded using the Delsys Trigno surface EMG system.
RESULTS: Results showed that muscular activation of tibialis anterior significantly decreased with increase in the level of inclination (p< 0.05). However, soleus, gastrocnemius medialis and gastrocnemius lateralis showed no significant differences (p> 0.05) in their muscular activation, and no noticeable trends were found. Furthermore, no significant difference was found between all the muscles at ground level and inclined level 2 and 4.
CONCLUSIONS: These differences in activation patterns found in distal extremity can be useful for designing rehabilitation protocols in sports training and for patients with neurological and musculoskeletal pathologies.

摘要：
背景：倾斜步行与多种肌肉骨骼益处相关，被认为是一种治疗性锻炼。在正常肌肉中观察到倾斜表面的肌肉激活增加和减少的各种模式，更专注于下肢近端肌肉组织。
目的：本研究的目的是评估腓肠肌肌电图激活的差异，比目鱼,步态过程中不同倾斜表面的胫骨前肌。
方法：14名年龄在17-30岁之间的健康男性参与者在0、2和4度的倾斜度上在电动跑步机上以自我选择的速度行走。使用DelsysTrigno表面EMG系统记录肌肉的EMG活性。
结果：结果表明，胫骨前肌的肌肉激活随着倾斜水平的增加而显着降低（p<0.05）。然而,比目鱼,内侧腓肠肌和外侧腓肠肌的肌肉激活没有显着差异（p>0.05），没有发现明显的趋势。此外，在地面水平和倾斜水平2和4的所有肌肉之间没有发现显着差异。
结论：在远端肢体中发现的这些激活模式的差异可用于设计运动训练中的康复方案以及患有神经和肌肉骨骼疾病的患者。
