What type of testing measures objective force to assess muscle strength?

Dynamometry is a testing method specifically designed to measure the force exerted by muscles, thereby providing an objective assessment of muscle strength. This technique typically utilizes a dynamometer, an instrument that quantifies the strength of muscles by measuring the force applied during a contraction. This approach is particularly useful in rehabilitation settings and sports science, where precise data on muscle performance can inform training programs and recovery protocols.

In contrast, flexibility testing evaluates how far a joint can move, grip testing focuses on measuring the strength of the hand's grip, and cardiovascular testing assesses the efficiency of the heart and lungs during exertion. While grip testing can indeed be a measure of muscle strength, it is a specific type and does not encompass overall muscle strength assessment like dynamometry does. Therefore, dynamometry stands out as the most comprehensive and objective method among the options provided.
