Currently eight out of the top ten ranked male shot putters in the world use the rotational shot put technique and the men's shot put world record was thrown by an athlete using the rotational shot put technique. Currently, the top ranked female shot putters do not use the rotational technique as they continue to use the glide technique at the elite level. The purpose of this study was to examine the rotational shot put technique used by females and males and to determine if there were any biomechanical differences between the genders. Eighteen subjects were filmed for this study---ten male and eight female rotational shot putters from NCAA division II universities and colleges and the University of Alberta. Fifty-one variables were measured using Dartfish TeamPro 4.0.7 software, and Microsoft Excel and StatView 4.0 were used for the statistical analysis. The females showed significantly shorter throw distances than the males by 3.02m (p≤0.001). Several additional differences between variables measured were found to be significant between the males and females with the main differences occurring in the second turn. In order to determine which variables best determine throw distance, correlation and forward stepwise multiple regression analyses were conducted. Vertical velocity was found to have the strongest relationship to male throw distance (r=0.602) but trunk flexion at maximum backswing was found to have the strongest relationship to female throw distance (r=-0.771). Stepwise regression analysis of the female group identified 5 variables as the key predictors of throw distance, 3 of which occur during the second turn. Stepwise regression analysis of the male group identified 7 variables which explained over 99% of the variation in throw distances, and 6 of these variables occurred in the second turn
