  • glycogen
  • Glycogen content and glycogen synthase activity in resting muscle were normal in MIRKO mice, and exercise, but not insulin, increased glycogen synthase activity. (jci.org)
  • In conclusion, normal expression of muscle insulin receptors is not needed for the exercise-mediated increase in glucose uptake and glycogen synthase activity in vivo. (jci.org)
  • The TPA treated and non-treated muscles were indistinguishable in terms of pre-contraction content of adenine nucleotide, creatine phosphate, lactate and glycogen, as well as contractile performance and contraction-induced glycogenolysis. (edu.au)
  • connective
  • The study shows how the force from a muscle depends on the complex interactions between the muscle fibers and connective tissues and the region of muscle that is active. (frontiersin.org)
  • Medically known as medial tibial stress syndrome, shin splints occur during physical activity and result from too much force being placed on your shinbone and connective tissues that attach your muscles to the bone. (boneclinic.com.sg)
  • Shin splints are caused by excessive force (overload) on the shinbone and the connective tissues that attach your muscles to the bone. (boneclinic.com.sg)
  • triceps surae
  • This work describes some clinical aspects of the recovery of minced triceps surae of the rat, and establish a correlation with the mechanical recovery of the regenerating muscles. (springer.com)
  • The fractional anisotropy (FA), λ 1 , λ 2 , λ 3 , mean diffusivity (MD), and T 2 values in the triceps surae muscles were measured by magnetic resonance diffusion tensor and spin-echo imaging. (wiley.com)
  • Davies CTM, Rutherford IC, Thomas DO (1987) Electrically evoked contractions of the triceps surae during and following 21 days of voluntary leg immobilization. (springer.com)
  • This study investigates the motor unit recruitment patterns between and within muscles of the triceps surae during cycling on a stationary ergometer at a range of pedal speeds and resistances. (royalsocietypublishing.org)
  • induces
  • We conclude that long-term use of high-heeled shoes induces shortening of the GM muscle fascicles and increases AT stiffness, reducing the ankle's active range of motion. (biologists.org)
  • 1988
  • The skeletal muscles of S. etruscus are also able to contract very rapidly: a respiratory rate of up to 900 min -1 (15 s -1 ) was measured, a stride frequency of 780 min -1 (13 s -1 ) is estimated from an allometric equation given by Heglund and Taylor ( 1988 ) and, during cold tremor, Kleinebeckel et al. (biologists.org)
  • mechanisms
  • It is not meant to be a review on such a wide topic, but it will tell the story of how the understanding of the mechanisms underlying the heterogeneity and plasticity of skeletal muscle power output has been developing in our laboratory and of how our experimental approach has been updated to further our knowledge of the mechanisms from the cellular level to the molecular level.

  • Muscles within muscles: Do spatio-neural mechanisms underpin force production? (frontiersin.org)
  • They include the countless short-fibered, or smooth, muscles of the internal organs and power the digestive tract, the pupils of the eyes, and all other involuntary mechanisms. (thefreedictionary.com)
  • Skeletal muscle weakness in old age: underlying mechanisms. (springer.com)
  • So far, the mechanisms underlying muscle weakness in NM patients remain unclear. (jove.com)
  • To further understand the underlying cause for the age-associated decrement of mitochondrial density and function in equine skeletal muscle, expression of factors involved in mitochondria biogenesis and mitochondria-selective autophagy pathways, two of the most prominent quality control mechanisms that have been described, were analyzed.

  • eccentric
  • Six men performed ankle plantar flexion exercises with eccentric contraction. (wiley.com)
  • Isolated eccentric muscle training has become the dominant conservative management strategy for Achilles and patellar tendinopathy but, in some cases, up to 45 % of patients may not respond. (springer.com)
  • Metabolic
  • Snow, M. H.: Metabolic activity during the degenerative and early regenerated stages of minced skeletal muscle. (springer.com)
  • Tendon and ligament compliance allows elastic energy to be stored and returned to offset energy fluctuations of the body's center of mass during locomotion, conserving muscle work and reducing the metabolic energy cost of locomotor movement. (springer.com)
  • vivo
  • In the mdx mouse model of DMD, the pharmacological reduction of detyrosination in vitro ablates aberrant X-ROS and Ca(2+) signalling, and in vivo it protects against hallmarks of DMD, including workload-induced arrhythmias and contraction-induced injury in skeletal muscle. (nih.gov)
  • Dudley GA, Duvoisin MR, Convertino VA, Buchanan P (1989) Alterations of the in vivo torque-velocity relationship of human skeletal muscle following 30 days exposure to simulated microgravity. (springer.com)
  • Two skeletal systems were used, the in vivo rat gastrocnemius-plantaris-soleus muscle preparation, and the in vitro isolated soleus muscle preparation. (edu.au)
  • Here, we describe an in vivo animal model to measure torque and to produce a reliable muscle injury. (jove.com)
  • In this study, we have directly followed hyperpolarized [1-13C]lactate in rat leg muscle in vivo to confirm that muscle can indeed metabolize exogenous lactate. (ismrm.org)
  • rectus femoris
  • compared the rectus femoris moment-length relationship of high-performance athletes engaged in different disciplines, who chronically use this muscle at distinctly different lengths, and found that runners were relatively stronger at longer muscle lengths and cyclists stronger at shorter muscle lengths. (biologists.org)
  • nervous system
  • The nervous system can finely tune the performance of a given muscle adapting its power output to the motor task on a very short time base, milliseconds/seconds (phasic control). (springer.com)
  • occurs
  • The second part of the experiment investigated how the muscle contraction occurs in presence of multiple stimuli close in time to each other with constant 2 volt stimulus. (fromemuseum.org)
  • Because muscle injury is a random event that occurs under a variety of biomechanical conditions, it is difficult to study. (jove.com)
