Abstract: This paper attempts to compare the effects of load on the spine when subjected to varying load conditions. Change in total body height was used as an indirect measure of disc compression with the help of the apparatus called stadiometer. Fifteen male subjects were measured under different load situations classified as light, medium and heavy loads. During the three conditions, measurements of changes in height were taken in the morning before work and in the evening before resting. Comparisons were made using a repeated measures Analysis of Variance (ANOVA) with a significant level set at (0.05). The result showed that duration of dynamic activities has significant effect on the disc compression for the light and heavy load (P
