Sit and reach test (SRT)
The SRT is a static flexibility test that specifically measures the flexibility of the lower back and hamstring muscles. The SRT test starts with sitting on the floor, then subjects stretch out their legs straight ahead. Subjects place the soles of the feet flat against a box, lock both knees, press the legs flat to the floor and put the hands on top of each other to reach forwards. After reaching, the subject holds that position for at least one-two seconds while the distance from the zero point of the flexibility measuring ruler installed on the board is recorded. The measurement unit of this test is centimeters (cm).
