| Measure | Description | Time Frame |
|---|---|---|
| Lower extremities kinetic | Three dimensional motion data were collected using a Vicon camera system during walking. Using motion capture system data to calculate the hip, knee internal/external rotation moment and ankle inversion/eversion moment via inverse dynamics method. | 10 minutes before fatigue protocol start, 5 minutes after fatigue protocol completed, after one week, 10 minutes before fatigue protocol start, 5 minutes after fatigue protocol completed |
| Peak and average amplitude during stance phase | EMG data were collected using a Delsys, and Biopac EMG system during walking. Tibialis anterior/Peroneal longus/Abductor hallucis longus muscle activity were measured by electromyography (EMG). | 10 minutes before fatigue protocol start, 5 minutes after fatigue protocol completed, after one week, 10 minutes before fatigue protocol start, 5 minutes after fatigue protocol completed |
| Lower extremities kinematic | Lower limbs alignment, including hip, knee and ankle joints. Using motion capture system data to calculate the joint angles. | 10 minutes before fatigue protocol start, 5 minutes after fatigue protocol completed, after one week, 10 minutes before fatigue protocol start, 5 minutes after fatigue protocol completed |

| Peak and average amplitude during stance phase | EMG data were collected using a Delsys, and Biopac EMG system during walking. Medial gastrocnemius/Rectus femoris/Bicep femoris muscle activity were measured by EMG. | 10 minutes before fatigue protocol start, 5 minutes after fatigue protocol completed, after one week, 10 minutes before fatigue protocol start, 5 minutes after fatigue protocol completed |
| Time of completed fatigue protocols | Time of completed the course will be recorded. | 1 minutes after fatigue protocol completed |
| Inter-joint contact force | Hip, knee ,and ankle inter-joint contact force: Anybody modeling system is used to model the inter-joint contact force | 10 minutes before fatigue protocol start, 5 minutes after fatigue protocol completed, after one week, 10 minutes before fatigue protocol start, 5 minutes after fatigue protocol completed |
| Lower extremities kinetic | Three dimensional motion data were collected using a Vicon camera system during walking. Using motion capture system data to calculate the hip, knee flexion/extension, adduction/abduction moment and ankle dorsiflexion/plantarflexion, and adduction/abduction moment via inverse dynamics method. | 10 minutes before fatigue protocol start, 5 minutes after fatigue protocol completed, after one week, 10 minutes before fatigue protocol start, 5 minutes after fatigue protocol completed |
