Motor Units Model (Twitch Characteristics)

• Lead time
• Contraction time (Tc)
• Half relaxation time (Thr)
• Duration of the twitch (Ttw)
• Maximal force (Fmax)
• Fatigue

Muscle-Joint-Bone Complex

• Muscles: insertion and origin points, force arm, force angle, MUs
• Joints: degrees of freedom, maximal and minimal angles
• Links: mass, inertial moment, length
