For Isotonic muscle exercise, see Isometric exercise and Weight training.
For the term associated with muscle contraction, see isotonic (exercise physiology)
For the term in nuclear physics, see isotone

Isotonic literally translates to equal tension. The term is used in several different contexts. Image File history File links Emblem-important. ... Isometrics is a form of exercise involving the contraction of a muscle without the shortening of the angle of the joint. ... This article is about strength training using weight (gravity) to generate resistance to contraction. ... A top-down view of skeletal muscle A muscle contraction (also known as a muscle twitch or simply twitch) occurs when a muscle fiber generates tension through the action of actin and myosin cross-bridge cycling. ... The term Isotonic refers to a muscle contraction, either eccentric or concentric, that is not speed limited. ... Nuclear physics is the branch of physics concerned with the nucleus of the atom. ... Two nuclides are isotones if they have the same number of neutrons. ...


Isotonic solution bears the same chemical resemblance of the body’s blood, plasma and tears. All fluids in the body have a certain concentration, referred to as osmotic pressure. The body’s common osmotic pressure, which is isotonic, allows a consistent maintenance of body tissues. In order for a substance to be absorbed and used in the body’s metabolism, it must be transported in an isotonic state.


Isotonic solutions involve no net movement of molecules across non-perfect biological membranes. Solutions remaining in osmotic equilibrium with respect to a particular biological membrane are said to be isotonic. This is different to iso-osmotic solutions which involve no net movement of molecules when separated by a perfect semi-permeable membrane.

Effect of different solutions on blood cells
Effect of different solutions on blood cells

Cells have a semipermeable membrane that allows the diffusion (flow) of water, but not the dissolved compounds such as salt ions (solutes). Water diffuses across the membrane in direction of the higher concentrated solution in a process called osmosis, thereby generating osmotic pressure if the inside concentration is higher. Plant cells often rely on this osmotic pressure for structural support. Under isotonic conditions the concentrations of impermeable solutes, the osmolality, is the same inside and outside the cell and there is no osmotic pressure. A medium of lower osmolality is called hypotonic and one of higher osmolality is called hypertonic. Image File history File links Osmotic_pressure_on_blood_cells_diagram. ...

What is Isotonic? (335 words)
Isotonic is a word, and that's all, to a lot of people.
The fluid pressure of food or Isotonic solutions across semi-permeable membranes, such as the walls of the small intestine, is generally referred to as having a particular osmolarity or tonicity.
Isotonic products are formulated with the proper balance of fructose, d-glucose, citric acid, potassium bicarbonate and other key ingredients to assure that they are isotonic when properly prepared.
Isotonic - Memory Foam (1374 words)
Isotonic's ultra dense Visco-Elastic Foam is this material: a revolutionary heat and pressure sensitive substance that forms a soft yet precise mold around your body, while offering firm support at a deeper level.
Isotonic material is Visco-Elastic and made up of billions of spherical shaped, open cells that are temperature and weight sensitive, allowing it to become softer in warmer areas (where your body is making the most contact with the surface) and remain firmer in cooler areas (where less body contact is being made).
Isotonic material has a pure density of 4.0 lb/ft. Isotonic is trusted, "preferred" and carried by the largest retail chains and mail order catalog companies in the world.
