Abstract
This study was sot up to explore the validity of the frequently made statement that the average height of the young adult male's centre of gravity is 55% of his height. As a subsidiary aim the study also attempted to discover how far the position of the centre of gravity is affected by the weight of the subject. Fifty-six physical education students aged 18–22 years were used to measure the vertical position of the centre of gravity using a simple centre of gravity board technique. Linear regression analysis of the results with respect to the mass and height of the subjects yielded product-moment correlations for the height of 0·55 and for the weight of 0·46, showing the height to be more influential than the weight of the position of the centre of gravity and the very approximate nature of the original statement.
