How is flexibility typically assessed?

Flexibility is typically assessed through range of motion (ROM) tests, which directly measure how far a joint can move in a specific direction. These tests involve various techniques, such as goniometry, where an instrument called a goniometer is used to quantify the angle of joint movement, or functional tests that evaluate the ease of movement during specific activities, such as stretching or performing certain exercises.

This method provides insight into an individual’s flexibility and informs trainers or health professionals on how to design appropriate stretching and flexibility programs tailored to enhance physical performance or prevent injuries. The focus on measuring the range of motion distinguishes flexibility assessments from other fitness evaluations that might involve strength, cardiovascular endurance, or metabolic rates, which are not related to one's ability to stretch or move joints through their full extent.
