Contraction mapping — In mathematics, a contraction mapping, or contraction, on a metric space (M,d) is a function f from M to itself, with the property that there is some nonnegative real number k < 1 such that for all x and y in M, The smallest such value of k is … Wikipedia
contraction — 1. A shortening or increase in tension; denoting the normal function of muscle. 2. A shrinkage or reduction in size. 3. Heart beat, as in premature c..beat. [L. contractus, drawn together] after c … Medical dictionary
isotonic contraction — Contraction of a muscle, the tension remaining constant. Since the contractile force is proportional to the overlap of the filaments, and the overlap is varying, the numbers of active cross bridges must be changing … Dictionary of molecular biology
Muscle contraction — See also: Twitch and Tremor Top down view of skeletal muscle Muscle fiber generates tension through the action of actin and myosin cross bridge cycling. While under tension, the muscle may lengthen, shorten, or … Wikipedia
Length contraction — Length contraction, according to Hendrik Lorentz, is the physical phenomenon of a decrease in length detected by an observer in objects that travel at any non zero velocity relative to that observer. This contraction (more formally called Lorentz … Wikipedia
