Primary Outcome Measures :
  1. Lower extremities kinetic [ Time Frame: 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 ]

    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.


  2. Peak and average amplitude during stance phase [ Time Frame: 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 ]
    EMG data were collected using a Delyses, and Biopac EMG system during walking. Tibialis anterior/Peroneal longus/Abductor hallucis longus muscle activity were measured by electromyography (EMG).

  3. Lower extremities kinematic [ Time Frame: 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 limbs alignment, including hip, knee and ankle joints. Using motion capture system data to calculate the joint angles.


Secondary Outcome Measures :
  1. Lower extremities kinematic [ Time Frame: 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 ]

    Three dimensional kinematics were collected using a Vicon camera system during walking.

    Lower limbs alignment, including hip, knee and ankle joints. Using motion capture system data to calculate the joint angles.


  2. Peak and average amplitude during stance phase [ Time Frame: 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 ]
    EMG data were collected using a Delyses, and Biopac EMG system during walking. Medial gastrocnemius/Rectus femoris/Bicep femoris muscle activity were measured by EMG.

  3. Time of completed fatigue protocols [ Time Frame: 1 minutes after fatigue protocol completed ]
    Time of completed the course will be recorded.

  4. Inter-joint contact force [ Time Frame: 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 ]
    Hip, knee ,and ankle inter-joint contact force: Anybody modeling system is used to model the inter-joint contact force

  5. Lower extremities kinetic [ Time Frame: 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 ]

    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.
