Fred Wilt

Wilt's book Run Run Run was published in 1964 by Track & Field News. It contained chapters written by Wilt, notable coaches, including New Zealand's Arthur Lydiard, and Soviet gold medalist Vladimir Kuts, and went through six printings over the next ten years. In 1975, Wilt coined the term plyometrics while observing Soviet athletes warming up. He reached out to Dr. Michael Yessis, who had previously introduced this concept to the United States through Russian translation of Verkhoshansky's work. This inspired their later collaboration, to get this information out to U.S. coaches, and the book Soviet Theory, Technique and Training for Running and Hurdling. Wilt wrote and compiled multiple other books on track and field. After retirement from FBI he worked as head coach for the Cross Country and Track and Field Women's team at Purdue University.
