How tall are Olympic athletes?

When I was doing research for my book I came across the list if participants of the Olympics 2012. I wanted to check what the average height was of the athletes in every weight category.  After putting the results in a graph I discovered that there is a clear correlation between the discipline and the weight-height ratio. Athletes of striking combat sports (such as boxing and taekwando) are in average taller than fighters of grappling sports (such as wrestling and judo), which makes a lot of sense knowing that reach is an important advantage in striking sports while power will be more beneficial in grappling sports. Where in this graph are you?

The graphs of the Olympic of 2016 and more things to think about when choosing a weight category are in my new book “Making Weight and Everything Else
