Question

Flexibility of which of these muscle groups or body areas is assessed during the sit-and-reach test?

- hamstrings
- erector spinae
- lumbar spine
- hip flexors
A. 1,2, and 3 only
B. 1 and 3 only
C. 2,3, and 4 only
D. 2 and 4 only

Answer 1

The sit-and-reach test assesses the flexibility of the hamstrings and lumbar spine; thus, answer B. 1 and 3 only is correct.

Step-by-step explanation:

The sit-and-reach test is designed to assess the flexibility primarily of the hamstrings and the lumbar spine. When performing the test, an individual reaches forward as far as possible while seated, which stretches the muscles of the back of the thighs (hamstrings) and the lower back (lumbar spine).

The erector spinae, which includes the longissimus and spinalis groups, is not specifically assessed in this test as it primarily acts to extend the vertebral column, not to flex it. The hip flexors are also not the main focus of the test. Therefore, the correct answer to the student's question is B. 1 and 3 only, assessing the hamstrings and lumbar spine.
