Table 1 Overview of endurance parameters of the fatiguing measurements comparing PIMA vs. HIMA

From: Are there two forms of isometric muscle action? Results of the experimental study support a distinction between a holding and a pushing isometric muscle function

  1. Listed are the following items of each subject (Vpn; mean value of two measurements): the total isometric phase, the mean duration of all single isometric phases, the longest single isometric phase and the relation of the longest isometric phase to the total isometric phase. Furthermore the arithmetic mean (M), the standard deviation (SD) as well as the coefficient of variation (CV) and the results of the t-tests are displayed (α = .05). M1 = 1st measuring, M2 = 2nd measuring
