ABSTRACT
Background- Prolonged sitting is a part of sedentary lifestyle individuals with prolonged sitting are required to be involved in other physical activity to promote changes in posture. Performing certain movements after prolonged sitting could result in a low back injury. Prolonged sitting leads to tightness of the hamstring muscle it can cause a decrease in range of motion and can lead to different musculoskeletal problems. Prolonged sitting can increase spine height and decrease the lumbar range. After an extended period of sitting full lumbar flexion movement can increase low back pain.
Objective- This study will provide an understanding of hamstring muscle flexibility and changes in lumbar lordosis in collegiate students which sits for prolonged hours.
Method- A sample of 80 collegiate students will be taken from Galgotias University, Greater Noida. The measurement of hamstring muscles is done when the hip is kept at flexion of 90 degrees, the angle of knee flexion is calculated during active knee extension. (As measured with the universal goniometer) and angle of SLR (passive SLR) measured with a goniometer. Lumbar lordosis is measured by flexicurve.
Result- A sample of 80 students was taken with a lifestyle of prolonged sitting more than 6 hours daily. Hamstring muscles tightness which is measured by the angle of SLR and AKE test with a goniometer was found in mainly students with more than 12 hours of sitting and change in curvature of the lumbar spine was observed leading to passive stiffness of lumbar spine and decrease in lumbar lordosis angle which is measured with the help of flexicurve. The known connection of increased intradiscal pressure while sitting which cause a decrease in lordosis.
Conclusion- It has been concluded that an increase in hours of prolonged sitting may cause hamstring tightness. The significant correlation was found between hours of sitting and lumbar lordosis angle. Long sitting hours or prolonged sitting of the collegiate student changes the curvature of the lumbar spine that leads to a decrease in the lumbar lordosis angle.
Key words: Prolonged sitting, hamstring muscle, lumbar lordosis.
