• Altered gastrocnemius contractile behavior in former Achilles tendon rupture patients during walking 

      Stäudle, Benjamin; Seynnes, Olivier R.; Laps, Guido; Brüggemann, Gert-Peter; Albracht, Kirsten (Peer reviewed; Journal article, 2022)
      Achilles tendon rupture (ATR) remains associated with functional limitations years after injury. Architectural remodeling of the gastrocnemius medialis (GM) muscle is typically observed in the affected leg and may compensate ...
    • Distinct muscle-tendon interaction during running at different speeds and in different loading conditions 

      Werkhausen, Amelie; Cronin, Neil J.; Albracht, Kirsten; Bojsen-Møller, Jens; Seynnes, Olivier R. (Peer reviewed; Journal article, 2019)
      The interaction between the Achilles tendon and the triceps surae muscles seems to be modulated differently with various task configurations. Here we tested the hypothesis that the increased forces and ankle joint work ...
    • Medial gastrocnemius muscle fascicles shorten throughout stance during sprint acceleration 

      Werkhausen, Amelie; Willwacher, Steffen; Albracht, Kirsten (Peer reviewed; Journal article, 2021)
      The compliant nature of distal limb muscle-tendon units is traditionally considered suboptimal in explosive movements when positive joint work is required. However, during accelerative running, ankle joint net mechanical ...
    • Recovery from Achilles Tendon Repair: A Combination of Postsurgery Outcomes and Insufficient Remodeling of Muscle and Tendon 

      Stäudle, Benjamin; Seynnes, Olivier R.; Laps, Guido; Göll, Fabian; Brüggemann, Gert-Peter; Albracht, Kirsten (Peer reviewed; Journal article, 2021)
      Introduction: Achilles tendon rupture (ATR) patients have persistent functional deficits in the triceps surae muscle–tendon unit (MTU). The complex remodeling of the MTU accompanying these deficits remains poorly understood. ...
    • Sarcolab pilot study into skeletal muscle’s adaptation to long-term spaceflight 

      Rittweger, Jörn; Albracht, Kirsten; Flück, Martin; Ruoss, Severin; Brocca, Lorenza; Longa, Emanuela; Moriggi, Manuela; Seynnes, Olivier R.; di Giulio, Irene; Tenori, Leonardo; Vignoli, Alessia; Capri, Miriam; Gelfi, Cecilia; Luchinat, Claudio; Franceschi, Claudio; Bottinelli, Roberto; Cerretelli, Paolo; Narici, Marco (Journal article; Peer reviewed, 2018)
      Spaceflight causes muscle wasting. The Sarcolab pilot study investigated two astronauts with regards to plantar flexor muscle size, architecture, and function, and to the underlying molecular adaptations in order to further ...
    • Training-induced increase in Achilles tendon stiffness affects tendon strain pattern during running 

      Werkhausen, Amelie; Cronin, Neil J.; Albracht, Kirsten; Paulsen, Gøran; Larsen, Askild V.; Bojsen-Møller, Jens; Seynnes, Olivier R. (Peer reviewed; Journal article, 2019)
      Background: During the stance phase of running, the elasticity of the Achilles tendon enables the utilisation of elastic energy and allows beneficial contractile conditions for the triceps surae muscles. However, the effect ...
