Which of the following is not a subcomponent of strength?

Flexibility is considered a separate component of physical fitness and is not classified as a subcomponent of strength. Strength is typically defined through various means of muscle force production, which includes absolute muscular strength, muscular endurance, and power.

Absolute muscular strength refers to the maximum force that a muscle or group of muscles can exert in a single effort. Muscular endurance indicates the ability of a muscle or group of muscles to perform repeated contractions over time, while power relates to the explosive strength required for dynamic movements. These three factors are integral to assessing and developing overall strength capabilities in physical fitness programs.

Flexibility, on the other hand, pertains to the range of motion of joints and muscles and does not measure the force production capabilities of the muscular system. This distinction highlights why flexibility is not included in the definition of strength components.
