  2. 1. Post activation potentiation : Modulating factors and mechanisms for muscle performance

    Author : Paulo Gago; Ekblom Maria; Anton Arndt; Nicola Maffiuletti; Gymnastik- och idrottshögskolan; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Potentiation; twitch; triceps surae; knee angle; stiffnes; length changes; electromechanical delay; Medicin Teknik; Medicine Technology;

    Abstract : Introduction: Acute enhancements of muscle contractile properties and performance subsequent to a maximal or near maximal conditioning contraction are often termed post activation potentiation (PAP). Although still controversial, PAP is commonly linked to enhancements in the myosin regulatory light chain phosphorylation, leading to improvements in the excitation–contraction coupling. READ MORE

  4. 2. Cross transfer effects after unilateral muscle overuse : an experimental animal study about alterations in the morphology and the tachykinin system of muscles

    Author : Yafeng Song; Per Stål; Sture Forsgren; Fawzi Kadi; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Triceps surae; overuse; contralateral; muscle; muscle fiber; MyHC; capillary; tachykinin; substance P; NK-1R; inflammation; anatomi; Human Anatomy;

    Abstract : Unilateral exercise can produce certain contralateral strength effects. Deleterious events can be cross-transferred as well, as illustrated by a strict symmetry in some chronic inflammatory diseases. READ MORE

  5. 3. An Investigation of the Influence of Knee Flexion Angle on the Activity of the Triceps Surae Muscles during the Heel-Raise Test

    Author : Kim Hébert-Losier; S. John Sullivan; Anthony G. Schneiders; José A. García; Univeristy of Otago; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biomechanics; Electromyography; Triceps surae; Achilles tendon; Plantar flexion; Heel raise test; Physiotherapy; Rehabilitation; Musculoskeletal; Movement analysis; Muscle endurance; Maximum voluntary isometric contraction;

    Abstract : Background: The heel-raise test (HRT) is used in clinical practice and research to assess the triceps suare (TS) muscles. The test involves repetitive unilateral heel-raises in upright stance. The test is administered with the knee straight for gastrocnemius medialis (GM) and lateralis (GL), and with the knee bent for soleus (SOL). READ MORE

  6. 4. Neuromuscular adaptations to muscle fatigue during submaximal isometric contractions in man

    Author : Wolfgang N Löscher; Karolinska Institutet; Karolinska Institutet; []
    Keywords : isometric; electromyography; tremor; H-reflex; twitch; motoneuron; recruitment; la-afferents; recurrent inhibition; central fatigue; excitatory drive; gastrocnemius; soleus; triceps surae; tendon vibration; ischemia; Renshaw cellStockholm 1995;

    Abstract : During a sustained contraction, the force producing capacity of a muscle gradually decreases. In order to maintain a constant force output, the neuromuscular system has to adapt to the contractile fatigue process. READ MORE

  7. 5. Bilateral kinetic, kinematic, neuromechanical, and muscle-tendon properties of habitual runners

    Author : Tiago Canal Jacques; Anton Arndt; Rodrigo Bini; John Rasmussen; Gymnastik- och idrottshögskolan; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicin Teknik; Medicine Technology;

    Abstract : Achilles tendon overuse-related injuries are a frequent problem to habitual runners. Such injuries occur more often unilaterally and its etiology is associated to overloading of the tendon tissue. Inter-limb differences during running are a possible cause for overload due to eventual differences in the mechanical loading provided to each limb. READ MORE
