  • Skeletal muscle is highly adaptable and can change in size and strength in response to different types of physical activity. (golifescience.com)
  • The authors also note increased muscle fiber diameter, which is an indicator of repair and strength recovery. (healthmedicals.net)
  • Muscle strength testing is an important component of the physical exam that can reveal information about neurologic deficits . (goviss.best)
  • His son presented with cardiac conduction disturbance with no congenital heart or skeletal defect. (medscape.com)
  • We discuss implications of our model approach for enhancing muscle models in general, as well as a few aspects regarding the significance of phosphate kinetics as one contributor to muscle fatigue. (frontiersin.org)
  • Commonly, muscle fatigue, i.e., the decline of the generable force level over time, is differentiated between central fatigue , i.e., the inability of the neural network to provide sufficient stimulation, and peripheral fatigue , i.e., the inability of the muscle cells to provide energy through metabolic activities (cf.
