Abstract

The excellent paper by Ayalon et al. joins a growing line of studies that have looked into using isokinetic dynamometry for identifying submaximal muscular performance (feigned weakness). Invariably the protocols applied in these studies have used maximal performance as the baseline to which its submaximal counterpartwas compared. Furthermore, measurement of maximal performance preceded submaximal performance. Inasmuch as the ‘maximal performance’ component is concerned, the measurements in all studies were based on previously reported protocols which evolved to become standard. The same protocols were used for measuring the feigned weakness, the only variation being the instructions administered. It is this element that is the focus of this commentary.
