• submaximal
  • Three-dimensional force components were recorded during submaximal isometric wrist extensions on day 0, day 4, and before, during, and after saline-induced pain on day 2. (edu.au)
  • torque
  • Normal subjects exerted isometric torque at a rapid rate of contraction with different amplitude targets, and at different rates with a constant target. (nii.ac.jp)
  • With a decreasing contraction rate, the agonist volley decreased in the area in correlation with the peak of the torque derivative, retaining a constant duration, while the antagonist volley disappeared. (nii.ac.jp)
  • increases
  • Sustained isometric contractions for as long as 20 to 30 seconds have been associated with increases in the synthesis of actin and myosin in the muscle, (4,12) probably mediated by these same pathways. (thefreedictionary.com)
  • While isometric training increases strength at the specific joint angles of the exercises performed and additional joint angles to a lesser extent, dynamic exercises increase strength throughout the full range of motion. (wikipedia.org)
  • physiological
  • It is this neural training that causes several weeks worth of rapid gains in strength, which level off once the nerve is generating maximum contractions and the muscle reaches its physiological limit. (wikipedia.org)
  • indicate
  • Together, these preliminary observations indicate that the response to an isometric fatiguing contraction differs between the affected and less-affected side post-stroke, and may suggest that central mechanisms observed here as changes in firing rate are the dominant processes leading to task failure on the affected side. (frontiersin.org)
  • ankle
  • Performance was assessed by the isometric force at ankle positions of 1.57 and 0.70 rad and the time to produce 50% of the maximal force at 1.57 rad. (cdc.gov)
  • Reductions in isometric force were greater at an ankle position of 1.57 rad than at 0.70 rad. (cdc.gov)
  • It also functions to 'lock' the ankle, as in toe-kicking a ball, when held in an isometric contraction. (wikipedia.org)
  • exercise
  • isometric exercise (syn static exercise) exercise in which this condition obtains. (thefreedictionary.com)
  • High-load isometric exercise is considered an effective countermeasure against muscle atrophy, but therapeutic electrical stimulation for muscle atrophy is often performed without loading. (hindawi.com)
  • Isometric (static) exercise causes much less soreness, and concentric (shortening) exercise causes none. (wikipedia.org)
  • An isometric exercise tool is a device used to exercise most body parts including the wrist and is often used as part of physical therapy or in order to build muscle strength in a low impact manner. (wikipedia.org)
  • Isometric exercise tools perform exercises or strength test using static contraction of a muscle without any visible movement in the angle of the joint. (wikipedia.org)
  • New isometric exercise tools often used force gauges and a micro processor and then output the force onto an LCD screen or store the information later to be downloaded onto a computer. (wikipedia.org)
  • Substrates are depleted during exercise, resulting in a lack of intracellular energy sources to fuel contractions. (wikipedia.org)
  • interval
  • This produces a greater force than singular contractions by decreasing the interval between stimulations to produce a larger force with the same number of motor units. (wikipedia.org)
  • rate
  • During the sustained fatiguing contraction, the mean rate of change in firing rate across all detected MUs was greater on the affected side (-0.02 ± 0.03 Hz/s) than on the less-affected side (-0.004 ± 0.003 Hz/s, p = 0.045). (frontiersin.org)
  • Temporal motor unit recruitment, or rate coding, deals with the frequency of activation of muscle fiber contractions. (wikipedia.org)
  • subjects
  • We performed a study on a group of asymptomatic subjects that showed a lack of correlation between isometric grip strength and thenar MUNE. (hindawi.com)
  • These results suggest that rapid isometric contractions are controlled by an amplitude-modulated pulse of agonist activation, which is associated with a pulse of antagonist activation, while the pulse of the antagonist activation is variably utilized among subjects. (nii.ac.jp)
  • electrical
  • In the present study, we investigated the combined effectiveness of electrical stimulation and high-load isometric contraction in preventing muscle atrophy induced by hindlimb unloading. (hindawi.com)
  • On the other hand, in electrical stimulation with high-load isometric contraction, inhibition of the overexpression of cathepsin L and atrogin-1 mRNA in addition to calpain 1, calpain 2, and MuRF-1 mRNA was confirmed. (hindawi.com)
  • These findings suggest that the combination of electrical stimulation and high-load isometric contraction is effective as a countermeasure against muscle atrophy. (hindawi.com)
  • creatine
  • Creatine phosphate stores energy so ATP can be rapidly regenerated within the muscle cells from adenosine diphosphate (ADP) and inorganic phosphate ions, allowing for sustained powerful contractions that last between 5-7 seconds. (wikipedia.org)
