   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

   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

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

   Författare :Lena Norrbrand; Per Tesch; Ola Eiken; Per Aagaard; Mittuniversitetet; []

   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.

7. 5. Metabolic aspects of cardiac arrhythmias

   Författare :Sigfus Gizurarson; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kardiologi; Electrofysiologi; Djurexperiment; Metabolism;

   Sammanfattning : Cardiac arrhythmias are an important cause of mortality and morbidity in patients with cardiac diseases. Sudden death due to ventricular tachycardia and fibrillation (VT/VF) in the setting of acute myocardial infarction (AMI) and heart failure (HF) is a frequent cause of premature death. LÄS MER
