Aim. V sit and reach test have been proposed as an alternative to the classical sit and reach test because only a meter rule is need and his intraclass internal consistency and hamstring flexibility criterion measures are high. However, because no sit and reach box is used in the V sit-and-reach test and hip position is different from the sit and reach test, spine and pelvis postures could be different between both tests and could influence the score and criterion validity.
Methods. A hundred and two men and 96 women young adults performed three trials for the sit-and-reach test (SR), V sit-and-reach test (VSR) and passive straight leg raise (PSLR) (left and right leg) in a randomized order. When the subject reached forward as far as possible, comfort (visual analogue scale), score (ACUFLEX I Flexibility tester), thoracic, lumbar postures and pelvic tilt (with an inclinometer) were measured.
Results. The VSR showed a greater spine flexion and anterior pelvic tilt but lower score than SR (p<0.01), whereas no differences in comfort were found. The hamstring validity for sit-and-reach test was slightly higher (r = 0.56-0.74) than the VSR (r = 0.53-0.65) in both men and women.
Conclusion. The sit-and-reach test is a more preferable test over the VSR as measure of hamstring flexibility in young adults.
