When assessing static strength, which factor does not affect the measured value?

When assessing static strength, the moment of force that all muscles involved can produce does not affect the measured value because static strength is evaluated under isometric conditions where movement does not occur. In this scenario, strength is determined by the maximum force produced by the muscles without any change in their length, meaning the dynamics of muscle shortening or velocity do not apply.

Static strength relies primarily on the muscle's ability to generate force regardless of the velocity of contraction, hence why other factors like muscle cross-sectional area— which correlates with the amount of contractile tissue available for force generation— and skill in activating motor units, which influences how effectively the muscles can be recruited for the task, are more relevant to the assessment. In contrast, the moment of force, while critical in dynamic movements, becomes less variable when only assessing the force produced in a static hold, thereby establishing it as an unaffected element in this context.
