What method is commonly used for assessing flexibility?

The sit-and-reach test is widely recognized as a standard method for assessing flexibility. This test specifically measures the flexibility of the lower back and hamstring muscles, which are critical areas for a wide range of physical activities and overall functional movement. During the test, an individual sits on the floor with legs extended straight ahead and reaches toward their toes, with the distance reached indicating their flexibility level. This straightforward and easily accessible testing method makes it a popular choice in various settings, including schools and fitness assessments, offering a practical means to evaluate this aspect of physical fitness.

Other options, such as the Biodex system, are more complex and may assess various aspects of physical performance, but they are not as specifically dedicated to measuring flexibility as the sit-and-reach test. The aerobic capacity test assesses cardiovascular fitness, while the vertical jump test evaluates muscular power rather than flexibility. Therefore, the sit-and-reach test stands out as the appropriate method for flexibility assessment.
