An Introduction to Biomechanics

I recently came across a biomechanical analysis of the hammer throw at the 2009 World Championships in Berlin. While the report is brief, it perfectly illustrates a few points that all hammer throwers need to know.

Basic physics tells us that there are three main variables that impact the distance of the throw: (1) the velocity of the hammer at the time of release; (2) the angle of release; (3) and the height of release. Obviously other factors also come into play, such as the wind, the density of the air, and so on, but these factors are the same for everyone and cannot be influenced by the throw. The height of release also plays a relatively small role since it remains fairly constant despite attempts by Harold Connolly in his prime to try to throw will taller shoes.

When I was in Holland Frans Bosch introduced the concept of Positive Running to me. I thought it was thought provoking and should be put on the table for discussion. Frans was kind enough to translate some of his remarks on his idea into English. Read more
