Department of Health Sciences and Kinesiology Faculty Publications

Purpose: The purpose of this study was to investigate lower extremity neuromuscular activity patterns during gait transitions with continuously changing locomotion speeds.

Methods: Muscular activities related to gait transitions (walk to run and run to walk) induced by changing treadmill speed were compared to muscular activities during walk and run at constant speeds. All transition and constant speed conditions were conducted in similar speed range. Surface electromyographic activities of gluteus maximus (GM), rectus femoris (RF), vastus lateralis (VL), biceps femoris long head (BFL), tibialis anterior (TA), gastrocnemius (GA), and soleus (SL) were collected and analyzed. The influences of speed and …
