Isotonic (exercise Physiology)
In an isotonic contraction, tension remains the same, whilst the muscle's length changes. Isotonic contractions differ from isokinetic contractions in that in isokinetic contractions the muscle speed remains constant. While superficially identical, as the muscle's force changes via the length-tension relationship during a contraction, an isotonic contraction will keep force constant while velocity changes, but an isokinetic contraction will keep velocity constant while force changes. A near isotonic contraction is known as Auxotonic contraction. There are two types of isotonic contractions: (1) concentric and (2) eccentric. In a concentric contraction, the muscle tension rises to meet the resistance, then remains the same as the muscle shortens. In eccentric, the muscle lengthens due to the resistance being greater than the force the muscle is producing. Concentric This type is typical of most exercise. The external force on the muscle is less than the force the muscle is gene ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Isotonic Regression
In statistics and numerical analysis, isotonic regression or monotonic regression is the technique of fitting a free-form line to a sequence of observations such that the fitted line is non-decreasing (or non-increasing) everywhere, and lies as close to the observations as possible. Applications Isotonic regression has applications in statistical inference. For example, one might use it to fit an isotonic curve to the means of some set of experimental results when an increase in those means according to some particular ordering is expected. A benefit of isotonic regression is that it is not constrained by any functional form, such as the linearity imposed by linear regression, as long as the function is monotonic increasing. Another application is nonmetric multidimensional scaling, where a low-dimensional embedding for data points is sought such that order of distances between points in the embedding matches order of dissimilarity between points. Isotonic regression is use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tonicity
In chemical biology, tonicity is a measure of the effective osmotic pressure gradient; the water potential of two solutions separated by a partially-permeable cell membrane. Tonicity depends on the relative concentration of selective membrane-impermeable solutes across a cell membrane which determine the direction and extent of osmotic flux. It is commonly used when describing the swelling-versus-shrinking response of cells immersed in an external solution. Unlike osmotic pressure, tonicity is influenced only by solutes that cannot cross the membrane, as only these exert an effective osmotic pressure. Solutes able to freely cross the membrane do not affect tonicity because they will always equilibrate with equal concentrations on both sides of the membrane without net solvent movement. It is also a factor affecting imbibition. There are three classifications of tonicity that one solution can have relative to another: ''hypertonic'', ''hypotonic'', and ''isotonic''.A hypotonic s ...

Sports Drink
Sports drinks, also known as electrolyte drinks, are functional beverages whose stated purpose is to help Sportsperson, athletes replace water, electrolytes, and energy before, during and especially after training or competition. There are many perceived benefits and questions pertaining to the efficacy of use for sports and fitness performance. At times if used too much, in wrong cases (as most of nutritional items) they may hinder health or performance. The drinks, or some of their ingredients such as sugar, may not be suitable for certain conditions. Categories of sport drinks Sports drinks can be split into three major types: *Tonicity#Isotonicity, Isotonic sport drinks contain similar concentrations of salt and sugar as in the human body. *Tonicity#Hypertonic solution, Hypertonic sport drinks contain a higher concentration of salt and sugar than the human body. *Tonicity#Hypotonicity, Hypotonic sport drinks contain a lower concentration of salt and sugar than the human body ...
