  1. 1. Biomechanical analyses of flywheel resistance exercise : From a space- and ground-based perspective

    Författare :Maria Sjöberg; Ola Eiken; Elena Gutierrez-Farewik; Hans E Berg; Patrik Sundblad; Loren FZ Chiu; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; AnyBody Modeling System; concentric; eccentric; eccentric overload; inverse dynamics; knee extensors; microgravity; musculoskeletal deconditioning; net-joint moment; AnyBody Modeling System; excentrisk; excentrisk överbelastning; invers dynamik; knäextensorer; koncentrisk; ledmoment; mikrogravitation; muskuloskeletal nedbrytning; Teknik och hälsa; Technology and Health;

    Sammanfattning : Astronauts suffer degradation of postural muscles and weight-bearing bones during long-duration spaceflight. Resistance exercise is used as a primary countermeasure against these degradations. LÄS MER

  3. 2. Endogenous antioxidants in human skeletal muscle and adaption in energy metabolism : with reference to exercise-training, exercise-related factors and nutrition

    Författare :Michael B Svensson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :GSH; urate; Q10; Ubiquinone-10; myoblasts; muscle stem cells; high-intensity exercise; performance; overload training; adenine nucleotides; AMP deaminase; glycogen; carbohydrates.;

    Sammanfattning : The antioxidant homeostasis is determined by a wide array of interacting cellular antioxidants, as well as being influenced by the homeostasis in energy metabolism. Changes in antioxidant homeostasis, as a consequences of altered production of reactive oxygen species (ROS). and/or by changes in the resident levels of antioxidants. LÄS MER

  4. 3. Patellar tendinopathy : on evaluation methods and rehabilitation techniques

    Författare :Anna Frohm; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Biomechanics Bromsman; decline board; eccentric training; patellar tendon load; prospective randomized study; VISA-P score study; VISA-P score study; VISA-P score.;

    Sammanfattning : Background: Patellar tendinopathy is an increasingly common overuse and degenerative injury for recreational and elite athletes. The management of this injury is often difficult and frustrating and the treatment may take a long time. LÄS MER

  5. 4. Acute and early chronic responses to resistance exercise using flywheel or weights

    Författare :Lena Norrbrand; Per Tesch; Ola Eiken; Per Aagaard; Mittuniversitetet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; electromyography; flywheel; magnetic resonance imaging; resistance exercise; Sports; Idrott;

    Sammanfattning : Resistance exercise using weights typically offers constant external load during coupled shortening (concentric) and lengthening (eccentric) muscle actions in sets of consecutive repetitions until failure. However, the constant external load and the inherent capability of skeletal muscle to produce greater force in the eccentric compared with the concentric action, would infer that most actions are executed with incomplete motor unit involvement.

    Sammanfattning : Weight training typically offers constant external load during coupled shortening (concentric) and lengthening (eccentric) muscle actions in sets of consecutive repetitions until failure. However, skeletal muscle inherently has the capability to produce greater force in the eccentric compared with the concentric action, which allows for greater loading during the eccentric action, i.
