ISOMETRIC AND ISOMETRIC- m OPERATORS [PDF]
AKSIOMA: Jurnal Program Studi Pendidikan Matematika, 2017 This paper presents the definition, samples, and natures of isometric and isometric- m algebra operator for some in Hilbert space. In additions, the relationship of both operators will also be examined. To investigate natures of isometric and isometric- m operators, adjoint operators concepts and natures are required.

Validity and reliability of the ‘Isometric Exercise Scale’ (IES) for measuring ratings of perceived exertion during continuous isometric exercise [PDF]
, 2021 Purpose: Isometric exercise (IE) interventions have been shown to be effective at reducing resting arterial blood pressure (BP). IE intensity is generally determined using force, electromyography (EMG), heart rate (HR), or knee joint angle.

The Effects of Prioritizing Lead or Boulder Climbing Among Intermediate Climbers
Frontiers in Sports and Active Living, 2021 This study compared the effects of prioritizing lead climbing or boulder climbing on climbing-specific strength and endurance, as well as climbing performance. Fourteen active climbers were randomized to a boulder climbing training group (BCT: age = 27.2

On isometric and minimal isometric embeddings [PDF]
Duke Mathematical Journal, 1997 In this paper we study critial isometric and minimal isometric embeddings of classes of Riemannian metrics which we call {\it quasi-$k$-curved metrics}. Quasi-$k$-curved metrics generalize the metrics of space forms. We construct explicit examples and prove results about existence and rigidity.

Applying muscle synergy analysis to forearm high-density electromyography of healthy people
Frontiers in Neuroscience, 2022 IntroductionMuscle synergy is regarded as a motor control strategy deployed by the central nervous system (CNS). Clarifying the modulation of muscle synergies under different strength training modes is important for the rehabilitation of motor-impaired ...

Extrapolation of time series of EMG power spectrum parameters in isometric endurance tests of trunk extensor muscles [PDF]
, 1998 The aim of the present study was to test the viability of using short isometric contractions of trunk extensor muscles to perform an assessment of their endurance capacity. To this aim two types of analysis were performed.
