Cell biology
Effect of different solutions on blood cellsAn isotonic cellular environment occurs when an equal solute concentration exists inside and outside the cell. Water molecules flow in and out at an equal rate by osmosis, causing the cell size to stay the same. It will not lose or gain any solutes. Plant cells in an isotonic environment are flaccid, and they will wither. The equilibrium of water movement is unable to provide plant cells with internal pressure for structural support, and therefore plants prefer to live in a hypotonic environment. In this situation, the concentration of solutes inside plant cells is higher than outside, and the plants use active transport to transport solutes in. This also ensures the concentration of water will be higher outside plant cells than inside which ensures plant health.
Bio-chemistry
An isotonic solution has an equal amount of dissolved solute in it compared to the things around it. Typically in humans and most other mammals, the isotonic solution is 0.9 weight percent (9 g/L) salt in aqueous solution, this is also known as saline, which is generally administered via an intra-venous drip. It is a medium between hypotonic and hypertonic solutions. Red blood cells normally exist in a 0.9 percent salt solution (saline) with the same concentration of salt in the outside solution.
Athletics
This term is also used in relation to a sports drink with balanced mineralised levels mimicking the osmolality of blood. This property is claimed by their advertising campaign to increase physical endurance. The limited (6 rowers) scientific study they quote however attributes the 10% increase in endurance over water to the higher carbohydrate content.

Firstly the term current is what is called "isotonic solution" which means a solution of the same osmotic pressure as another solution.When two isotoic solutions are seoarated by an osmtic membrane,OSMOSIS DOES NOT TAKE PLACE,since the (Osmotic pressure on eitherside are same).
So isotonic dilution if you really are using the term in its strict sense ,will mean the solution at hand diluted to the required extent so that it is isotonic with a second ,reference solution.
Other terms are "hypertonic" and "hypotonic". "Hyper" meaning above the osmotic pressure of the reference, and "Hypotonic "means less.

An isotonic solution has an equal amount of dissolved solute in it compared to the things around it. The dilution to make an isotonic solution is known as isotonic dilution.
