This is not the case with weights since they have a static force which does not change with a change in position. It changes in length when it is stretched during a repetition and thus its resistance changes. The second variable is F 2, represents the force of the resistance band. When using a variable elastic resistance band instead of a dumbbell to perform a repetition, (not an isometric contraction hold just yet), there are now two variables in the equation. We will relate this to isometric training here shortly.

This is when the angle changes throughout the motion, thus constantly changing the value of the final moment of force calculation. When using a static weight such as a dumbbell, there is only one variable in this equation (F P = F1 x cosine (A)) and that is the angle “A” of the joint in which the calculation of the perpendicular force is determined prior to the final calculation of the moment of force, Mo.įor now, this assumes that one will be performing a repetition with the weight.

Once we know the value of F P, we can then determine the moment of force, M o, acting on the joint if we know the length of the moment arm, L A. F P, will never be greater than the original force, F 1, only less than or equal to it. Here, “A” represents the angle required to bring the force perpendicular to the moment arm and F 1 represents the original weight being exercised. If the angle of this force is some other number besides 90 or 180 degrees, the perpendicular equivalent force (F P) can be calculated by simple geometry by first determining the exact angle required to bring the force perpendicular.īy knowing the exact angle to bring the force perpendicular, we can calculate this new force, F P, on the moment arm as follows: The moment of force at the joint being exercised is first calculated by determining the perpendicular equivalent of the force acting on the moment arm, providing the angle of force (F 1) in relation to the moment arm, L A, isn’t already at 90 degrees and isn’t acting parallel to it either. Let’s leave aside any training strategy for a minute and focus on this first. One has to deal with the calculation of the moment of force at the joint being exercised. There are several differences between the two. The answer to your question, “How does isometric training with the resistance band differ from isometric training with weights?” is as follows:

While I don’t expect the average person without a professional background in anatomy and engineering mechanics to understand everything in the sample that I have prepared below, I think it’s worth at least answering this question “the best way I know how.” How does isometric training with the resistance band differ from isometric training with weights? Sometimes I feel that it would be a lot easier not to assume anything about the educational background regarding the person inquiring and simply answer their question the best and most accurate way I know how. There is no quick and easy way to answer their question in simple layman’s terms that everyone can immediately understand, without first explaining a few basic engineering principles regarding forces. Their initial gut feeling is that, “they’ve got to be the same”. Most of them don’t see a difference and would like to know. In particular, most would like to know how isometric training with the resistance band differs from isometric training with weights. We also receive similar requests from developers of other speed training programs and jump training programs to explain the same.
