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 ...

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 ...

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 ...

Journal of the London Mathematical Society, 1988
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

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 \(A'_ 2\).

Acquiring natural-looking in-betweens is a fundamental shape interpolation problem in computer graphics. Several previous studies showed that as-isometric-as-possible interpolation is the key to natural and intuitive results. With this presumption, this paper describes a novel method for acquiring an isometric shape interpolation for given key-frame ...

On the isometric equation of the sarcomere
Basic Research in Cardiology, 1974A model of the sarcomere is described, which is based upon (a) the sliding filament theory ofHuxley, (b) the ultrastructure of the sarcomere, (c) the biochemical mechanisms responsible for mechanical coupling and uncoupling of myosin and actin, (d) the constancy of the volume of the sarcomere and (e) a statistical analysis of random forces acting on ...

Level of Isometric Strength and Isometric Endurance in Repeated Contractions
Research Quarterly. American Association for Health, Physical Education and Recreation, 1966Abstract Thirty male subjects were given 20 trials of isometric wrist flexion on each arm. Each trial consisted of 5 sec. of maximum exertion followed by a 30 sec. rest period. Subjects were ranked on the basis of the first two trials for each of the limbs and divided into three groups of 10 subjects each representing high, middle, and low levels of ...

THE APPROXIMATION PROBLEM OF ALMOST ISOMETRIC OPERATORS BY ISOMETRIC OPERATORS
Acta Mathematica Scientia, 1988The strictly (theorized) ``equidistant operator'' does not come into existence. What can be seen in practice is ``almost equidistant'' operator. The description of ``almost equidistance'' is essentially a form of ``absolute error'', and in this paper we will study the ``almost equidistance (isometry)'' described by the form of ``relative error''.
