1. A study entitled "Humeral hypertrophy in response to exercise" written by H.J. Jones and colleagues was published in Journal of Bone and Joint Surgery in 1977. He used "roentgenograms" to take various measurements from the humerus bone of international tennis players playing and non-playing arms. Below are the data for cortical bone thickness at different locations on the humerus for each arm of these players.
