Isometric exercise, isometric strength and anthropometric measurements
Internationale Zeitschrift f�r Angewandte Physiologie Einschliesslich Arbeitsphysiologie, 19631. 29 young adult male subjects practiced 15 sec. of maximal isometric contractions of the elbow flexors three times a day, 5 days a week, for 5 weeks. They achieved greater increases in strength than have been claimed for a single two-thirds maximal contraction once a day, although the latter has been said to provide the maximal stimulus for the ...

ISOMETRIC AND ALMOST ISOMETRIC OPERATORS
Acta Mathematica Scientia, 1984The author introduces the approximation problem of almost isometry by isometry and some results for some spaces \(B(E,E_ 1)\). Following \textit{E. Michael} and \textit{A. Pelczynski} [Isr. J. Math. 4, 189-198 (1966; Zbl 0151.176)] the author calls such operator \(T\in B(E,E_ 1)\) an \(\epsilon\)-isometry, if \((1-\epsilon)\| x\| \leq \| Tx\| \leq (1 ...

It is known [see \textit{S. Wagon}, Can. Math. Bull. 26, 337-340 (1983; Zbl 0486.51013)] that a ball in \({\mathbb{R}}^ n \)cannot be decomposed into m sets (2\(\leq m\leq n)\) that are mutually isometric under rotations and translations of \({\mathbb{R}}^ n.\) The author of the present paper considers some related problems concerning decompositions of

Cardiology Clinics, 1992
A number of normal daily and athletic activities require isometric or static exercise. Such sports as weight lifting and other high-resistance activities are used by athletes to gain strength and skeletal muscle bulk. However, static exercise also causes significant increases in blood pressure, heart rate, myocardial contractility, and cardiac output ...

Boundedly isometric but not isometric spaces
Siberian Mathematical Journal, 1993Two metric spaces \((M_ i, d_ i)\), \(i=1,2\), are called boundedly isometric if for every bounded set \(A_ 1\subset (M_ 1, d_ 1)\) there is a bounded set \(A_ 2\subset (M_ 2, d_ 2)\) isometric to \(A_ 1\) and if for every bounded set \(A'_ 2\subset (M_ 2, d_ 2)\) there is a bounded set \(A'_ 1\subset (M_ 1, d_ 1)\) isometric to \(A'_ 2\).

To the Editor. —The Editorial entitled "Isometric Exercise Testing: Usefulness and Limitations" by Dr Stefadouros, published in the JanuaryArchives(1983;143:26-27), began with a statement that brought me up short: "... Isometric exercise [is] a form of exercise where the contracting muscles develop force without shortening." Can this be so?

Abstract Flute playing involves a great deal of “muscle action developing tension while the muscle is prevented from contracting.” This is simpler than it seems: equilibrium is achieved when forces involved in a system are evenly distributed and balance each other.
