Isometric strength is defined as the capacity to produce force or torque with a voluntary isometric muscle[s] maintain[s] a constant length contraction.

The key thing to understand about this type of contraction and strength measurement is that no body movement occurs during the measurement period. The tested person’s body angles and posture remain the same throughout the test. Isometric strength has historically been the type most studied and measured. It is probably the easiest to measure and to understand.

Some strength researchers feel that isometric strength data may be difficult to apply to some “real life” situations because in most real circumstances people are moving – they are not static. Other researchers counter that it is equally difficult to determine the speed of movement of a person or group of persons doing a job each moves in his or her unique manner and speed across the links and joints of the body.



In truth, neither is better – they are different measurements. Both researchers and users should collect and use data that they understand and that fits their application. Workplace Isometris When a worker is called on to perform a physically demanding lifting task, the external load produces moments – tendencies to produce motion, also called torques – about various joints of the body.

For example, in a biceps curl exercise, the moment produced by the forearm flexors must counteract the moment of the weight held in the hands as well as the moment caused by gravity acting on the forearm’s center of mass.

To perform the task successfully, the muscles responsible for moving the joint must develop a greater moment than the combined moments of the external load and body segment.

It should be clear that, at each joint of the body, there is a limit to the strength that the muscle can produce to move ever-increasing external loads.

This concept forms the basis of isometric muscle strength prediction modeling. First, workers are observed and usually photographed or video-taped as they perform physically demanding tasks.

For each task the posture of the torso and the extremities are documented at the time of peak exertion. The postures are then re-created using a computerized software package, which calculates the load moments produced at various joints of the body as the task is performed. The values obtained during this analysis are then compared to population norms for isometric strength obtained from a population of industrial workers.


In this manner, the model estimates the proportion of the population. National Institute for Occupational Safety and Health. You May Also Like: Physical Strength Iometrics in Ergonomics – 1. Gallagher, Sean; Moore, J.

Steven; Stobbe, Terrence J. Humankind’s interest in measurement of human physical strength probably dates to the first humans. At that time, life was truly a isometrucs in which the fittest survived.

To a great extent, fittest meant strongest. Interestingly, current interest in h Kroemer and Kroemer et al. Several strength assessment procedu In spite of advances in measurement techniques and an explosive increase in the volume of research, our understanding of human strength remains in its introductory stages.

It is clear that muscle strength is a highly complex and variable function tha The concept of isokinetic measurement of strength was originally related by Hislop and Perrine. Strictly speaking, a means of speed control,
