During contraction, there is a spatial reorganization of the contractile machinery to optimize force development.

During the nineties, countries like Mexico, Argentina, Malaysia, Turkey, Colombia, Indonesia, Korea and Peru all experienced boom – bust cycles with the consequent collapse in GDP, consumption, non-tradable output sector contraction, capital flow reversals, limited or costly access to capital markets and sharp real exchange rate fluctuations.

During intense muscle contraction the ion pumps that maintain homeostasis of these ions are inactivated and this ( with other ion related disruption ) causes ionic disturbances.

During the ventricular contraction portion of the cardiac cycle, the Purkinje fibers carry the contraction impulse from both the left and right bundle branch to the myocardium of the ventricles.

During the era of route contraction from 1940 to about 1975 the Franklin Avenue Shuttle, as it is now known, seemed a prime candidate for abandonment ; its physical structure had been allowed to deteriorate and its service steadily curtailed.

During the contraction the core becomes hotter and hotter until it causes the outer layers to begin fusing hydrogen and expand outwards initiating the red giant stage.

During ventricular contraction, the wave of depolarization moves from endocardial to epicardial surface.

During this phase, the male urethral sphincter contracts ( so as to prevent urine from mixing with semen, and guard against retrograde ejaculation ) and muscles at the base of the penis begin a steady rhythmic contraction.

During ventricular contraction, or systole, some of the blood from the left ventricle leaks into the right ventricle, passes through the lungs and reenters the left ventricle via the pulmonary veins and left atrium.

During contraction of muscle, rapidly cycling crossbridges form between activated actin and phosphorylated myosin, generating force.

During an eccentric contraction, the muscle elongates while under tension due to an opposing force being greater than the force generated by the muscle.

During an eccentric contraction of the biceps muscle, the elbow starts the movement while bent and then straightens as the hand moves away from the shoulder.

During an eccentric contraction of the triceps muscle, the elbow starts the movement straight and then bends as the hand moves towards the shoulder.

During an eccentric contraction, the filaments slide past each other the opposite way, though the actual movement of the myosin heads during an eccentric contraction is not known.

During the drive, the foot may extend also, by a flexing of the soleus and gastrocnemius muscle in the calf.

During N1, the subject loses some muscle tone and most conscious awareness of the external environment.

During a spring training game against the Chicago White Sox in 1963, the Reds ' regular second baseman, Don Blasingame, pulled a groin muscle ; Rose got his chance and made the most of it.

During infancy, subjects should undergo therapies to improve muscle tone.

During exercise, the water level retracts due to the increase in concentration of lactic acid in the muscle cells.

During acute toxoplasmosis, symptoms are often influenza-like: swollen lymph nodes, or muscle aches and pains that last for a month or more.

During the summer he refined the assay procedure further and upon returning to Spain he and Valdecasas submitted a paper describing the work to the Journal of Biological Chemistry, where it was rapidly accepted S., and Valdecasas, J. G. ( 1929 ) A micromethod for the estimation of total creatinine in muscle.

During abduction of the arm, moving it outward and away from the trunk, the rotator cuff compresses the glenohumeral joint, a term known as concavity compression, in order to allow the large deltoid muscle to further elevate the arm.

During the 1980s, the deregulated Conrail had the muscle to implement the route reorganization and productivity improvements that the PC had unsuccessfully tried to implement during 1968 to 1970.

During this time, judging in professional bodybuilding competitions started placing greater emphasis on muscle mass, with many bodybuilding traditionalists commenting that muscle mass had now become the most important factor to winning, even greater than that of symmetry, aesthetics, and proportion.

During the 2010 season, Wood was placed on the disabled list until May 8 due to an upper back muscle strain.

During Sultanas time in port, men tried to muscle, bribe, and threaten their way on board, until the ship was bursting at the seams with soldiers.

During repeated cycling tests in young healthy adults an energy drink significantly increased upper body muscle endurance.

During exercise, despite decreased insulin concentrations, muscle increases GLUT4 translocation and therefore glucose uptake.

During ejaculation the smooth muscle in the walls of the vas deferens contracts reflexively, thus propelling the sperm forward.

During stimulation of the muscle cell, the motor neuron releases the neurotransmitter acetylcholine, which travels across the neuromuscular junction ( the synapse between the terminal bouton of the neuron and the muscle cell ).

During lab tests, subjects are known to have very high voltages of electroencephalography ( EEG ) delta activity, an increase in muscle tone, and a doubled increase in heart rate, if not more.

During an attack, a person may also experience muscle weakness, seizures, and mental changes such as anxiety and hallucinations.

During muscle stimulation, AMP increases while ATP decreases, which changes AMPK into a good substrate for activation via an upstream kinase complex, AMPKK, or better, where binding of AMP renders activated AMPK that is phosphorylated at Thr-172 a worse substrate for protein phosphatase 2Calpha.

During a bout of exercise, AMPK activity increases while the muscle cell experiences metabolic stress brought about by an extreme cellular demand for ATP.

During a single acute exercise bout, AMPK allows the contracting muscle cells to adapt to the energy challenges by increasing expression of hexokinase II, translocation of GLUT4 to the plasma membrane, for glucose uptake, and by stimulating glycolysis.
