Based on examination on 288 examinees, males and females, it is determined that magnitude of spinal column movement depends on duration of worm up exercises. The sample is taken from 3rd grade students of Secondary schools in Niksic. Tests used for measuring mobility of spinal column in sagital plane Are touch-toe and touch-heels. The measurement is done before and after worm up exercises, but in groups with different duration of 5, 10 and 15 minutes. There are differences in results between time groups and between males and females. This research proves that there are differences in mobility of spinal column depending on time of worm-up body exercise. .
