In the past, studies have shown that the sit and reach along with altered versions show validity for evaluating hamstring flexibility. However, they do not show a correlation to the assessment of lumbar flexibility. Nevertheless, within this article, they discussed how the hip joint, lumbar and thoracic spine contribute to the overall performance of Sit and Reach. This test was performed on 195 Brazilian boys ages 18 to 19. All individuals volunteered, weighed 152.02 ± 22.46 lbs. and had an average height of 69.29 ± 2.76 inches. The tests scrutinized each kinematic angle to make an overall observation of the body segments used for trunk flexion. In turn, three markers were labeled with tape on the individual being tested. These markers included the plateau area affiliated with the fifth lumbar vertebra, the second on the twelfth thoracic vertebra and the third on the seventh cervical vertebra. Each test was performed 3 times, and then the average of the three was documented. Furthermore, these measurements were then divided by the overall expected measurement for their age, gender, etc. and then recorded as a percentage. The results showed the thoracic spine to be 46.01±7.32%, lumbar spine to be 12.68±5.12%, and hip performance to be 41.31±7.19% separately. In the future, assessments of the hip joint flexion, lumbar and thoracic spine measurements should be performed individually to allow for separate by
