Abstract:
Intervertebral discs contribute one fourth of the total vertebral column height. IVD allow the movement between vertebral bodies and transmit the forces and the basis for locomotion .When the axial compression is greater than interstitial osmotic pressure ,water extrude through the disc wall and result in decrease in the height and total body height .During day ,due to constant force of gravity and muscular activity. This study was to find out whether low intensity exercise reduces vertebral column height. The low intensity exercise was 20 min jogging in the ground. The C7 and S2 spinous process were palpated and marked with a dot on the skin over the middle of the spinous process of 20 asymptomatic subjects of age group 18-21. It was measured before running and recorded vertebral column height. The subjects were allowed to run for 20 minutes in low intensity. Following the run, the subjects were aligned to palpate the C7 and S2 spinous process and the second vertebral column height measurement was taken. Height of the subject also measured prior and after the exercises by using stadiometer. This study shows that there is significant height difference (p<0.05) and No significant change in Vertebral Column Height / Trunk height (P = 0.098) after low intensity exercise. This study concludes that there is no statistically significant reduction in vertebral column height after low intensity exercises, which have a high clinical relevance.
