Flexibility of which body areas is assessed during the sit-and-reach test?

• A. hamstrings and lumbar spine
• B. erector spinae and hip flexors
• C. hamstrings, erector spinae, and lumbar spine
• D. erector spinae, lumbar spine, and hip flexors

Answer: (A)

The sit-and-reach test mainly evaluates the flexibility of the hamstrings and the lumbar spine. In this test, you sit with legs straight and reach forward along a measuring scale. The distance you can reach is mostly limited by how much your hamstrings can lengthen with the knees extended and by how much your lower back (lumbar spine) can flex to allow the trunk to bend forward. If your hamstrings are tight, you won’t reach far, even if your spine could bend more; if your lumbar spine is stiff, your reach is limited too. The erector spinae and hip flexors do influence the movement somewhat, but they are not the primary areas the test is designed to assess.
