A Simplified Method for Considering Achilles Tendon Curvature in the Assessment of Tendon Elongation

Kharazi, Mohamadreza; Theodorakis, Christos; Mersmann, Falk; Arampatzis, Adamantios; Bohm, Sebastian

The consideration of the Achilles tendon (AT) curvature is crucial for the precise determination of AT length and strain. We previously established an ultrasound-kinematic-based method to quantify the curvature, using a ...

Contractile Work of the Soleus and Biarticular Mechanisms of the Gastrocnemii Muscles Increase the Net Ankle Mechanical Work at High Walking Speeds

Kharazi, Mohamadreza; Theodorakis, Christos; Mersmann, Falk; Bohm, Sebastian; Arampatzis, Adamantios

Increasing walking speed is accompanied by an increase of the mechanical power and work performed at the ankle joint despite the decrease of the intrinsic muscle force potential of the soleus (Sol) and gastrocnemius medialis ...

Quantification of Achilles tendon force and triceps surae muscle energy production during human locomotion

Kharazi, Mohamadreza

Aktuelle In-vivo-Methoden zur Bewertung der Belastung und Dehnung der Achillessehne (AT) in der biomechanischen Literatur haben bestimmte Einschränkungen, die sorgfältig berücksichtigt werden müssen. Daher hatte die erste ...

Quantifying mechanical loading and elastic strain energy of the human Achilles tendon during walking and running

Kharazi, Mohamadreza; Bohm, Sebastian; Theodorakis, Christos; Mersmann, Falk; Arampatzis, Adamantios

The purpose of the current study was to assess in vivo Achilles tendon (AT) mechanical loading and strain energy during locomotion. We measured AT length considering its curve-path shape. Eleven participants walked at 1.4 ...
