Isometric


Definition:

  • (a.) Alt. of Isometrical

Example Sentences:

  • (1) Circular muscle strips from the opossum esophageal body obtained 3-5 cm above the esophagogastric junction were suspended in organ baths for measurement of isometric tension.
  • (2) It may, however, be useful to compare local wall dynamics in the more isometrically-contracting basal segment with those in the middle portion which brings about most of the emptying of the ventricle.
  • (3) The power spectrum of the EMG was analyzed during isometric contractions of the shoulder muscles.
  • (4) Rings of isolated coronary and femoral arteries (without endothelium) were suspended for isometric tension recording in organ chambers filled with modified Krebs-Ringer bicarbonate solution.
