How to remember the difference between isometric, isotonic, and isokinetic exercises
- Isometric means " same length ," so that your muscles do not get longer or shorter by bending a joint.
- Isotonic means " same tension " so that the weight on your muscles stays the same.
- Isokinetic means " same speed " so that your muscles are contracting at the same speed throughout the workout.
What is the difference between terms isotonic iso-osmotic?
Isoosmotic VS Isotonic Solution
- Solutions having same osmolarity are known as isoosmotic solutions.
- Solutions having same tonicity are known as isotonic solutions.
- Solutions having tonicity like that of plasma are known as isotonic solutions with respect to plasma.
What is the difference between isotonic and hypertonic?
What are examples of hypertonic solutions?
- 3% Saline.
- 5% Saline.
- 10% Dextrose in Water (D10W)
- 5% Dextrose in 0.9% Saline.
- 5% Dextrose in 0.45% saline.
- 5% Dextrose in Lactated Ringer’s.
What does it mean to say two solutions are isotonic?
In the general sense, two solutions are isotonic when they contain the same amounts of solutes, or dissolved substances, and therefore have the same osmotic pressure. As commonly used in the medical field, though, isotonic solutions are solutions which have the same concentration of solute as the cells in the human body.
What is the difference between isotonic and hypotonic?
- Isotonic -The osmotic pressure outside the cells is the same as the osmotic pressure inside the cells.
- A hypotonic solution will have a lower concentration of solutes than the cell. ...
- A hypertonic solution will have a higher concentration of solutes than the cell and will have a higher osmotic pressure outside the cell than inside the cell.
Is an isotonic solution always Isosmotic?
The bottom line: isosmotic solutions are not always isotonic. Hyperosmotic solutions are not always hypertonic. But hyposmotic solutions are always hypotonic. The response to this rapid fire presentation of osmolarity and tonicity was overwhelmingly positive.
What is isotonic solution and Isosmotic solution?
Isotonic solution-An isotonic solution refers to two solution has the same solute concentration across a semipermeable membrane. There. Isoosmotic solution-An isoosmotic solution refers to two solution has different different osmotic pressure. Generally all Isoosmotic solutions are Isotonic solution.
What is a Isosmotic solution?
Definitions of isosmotic solution. a solution having the same osmotic pressure as blood. synonyms: isotonic solution.

How is Isosmotic but not isotonic?
The key difference between isotonic and isosmotic is that isotonic solutions contain only non-penetrating solutes whereas isosmotic solutions contain both penetrating as well as non-penetrating solutes.
What happens to a cell in an Isosmotic solution?
When a red blood cell is placed in an isotonic solution, there will be no net movement of water. Both the concentration of solute and water are equal both intracellularly and extracellularly; therefore, there will be no net movement of water towards the solution or the cell.
Why is urea Isosmotic but not isotonic?
The effects of isosmotic urea. This is because, although isosmotic, the urea solution is not isotonic, as urea can freely diffuse across the cell membrane into the cell via passive diffusion and through urea transporters (20, 21). This leads to a change in cell volume as a result of osmotic water movement (13).
What is an Isosmotic environment?
(1) (used of solutions) Of or having the same or equal osmotic pressure. (2) A condition in which the total number of solutes (i.e. permeable and impermeable) in a solution is the same or equal to the total solutes in another solution. Supplement. Word origin: G.
Most recent answer
2 % boric acid has the same osmotic pressure as the contents of the blood cells as determined by the freezing point method, thus it is iso-osmotic with blood. But since it crosses the erythrocyte cells, it essentially acts like water (always hypotonic with blood) regardless of its concentration, causing hemolysis.

Isotonic and isoosmolar are often used interchangeably, and this is true if the solutes on both sides of the Pfeffer-cell's membrane cannot cross it. However, if you place erythrocytes in an isoosmolar solution of urea, they will burst. This is, because urea can cross the cell membrane, taking water with it.

What is isotonic exercise?
Isotonic Exercises. Isotonic Exercises are the everyday workouts you do at the gym which involves a range of motion. It involves your muscles contracting – either shortening or lengthening. Isotonic comes from the Greek “iso-“, equal + “tonos”, tone = maintaining equal (muscle) tone.
How to do isometric exercises?

What muscles did Superman work?
For isotonic exercise, lie down facing the floor, and lift your hands and legs high. For isometric exercise, hold your hand and legs as high as you can. Muscle worked: gluteus maximus, Hamstrings, erector spinae.
What is eccentric muscle contraction?
Eccentric Muscle Contraction. Now slowly release the tension and let your arm come back to the initial position. As your forearm lowers, the resistance of the can is more than the energy you put in. Therefore, the muscle lengthens, but still contracts – it is eccentric muscle contraction.
Can you mix isotonic and isometric?
Combination of both is ideal for any workout plan. If an isotonic workout has an isometric sister then you should mix both and see which ones give you more burn. The woman holding a plank position by no means is an easy workout. Planks holds are known more their difficulty.
