Professor Paavo V Komi of University of Jyväskylä, Finland is longer with us. He was a major contributor and a research giant in the field of strength and power training. Komi’s main expertise was in sports biomechanics, and his greatness was in bridging the gap between complex science, engineering and neuro-physiology on one hand and applied sports. For example, numerous World- and Olympic Champions competing in the Finnish “national sports” ski-jumping and javelin throwing were involved and able to profit from applied research conducted in Komi’s laboratory. Komi was instrumental in building a laboratory at the University of Jyväskylä that has gained world recognition. He was a driving force in establishing and as a President operating the European College of Sports Science. Komi’s work and lectures on the stretch shortening cycle had immense impact in appreciating how the series an parallel elastic components of skeletal muscle contributes to athletic performance. As a Post Doc student with Prof. Buskirk at Penn Sate, Komi did a landmark research study on eccentric and concentric strength training that turned out to be an inspirational source that lead up to the birth of the YoYo technology. Komi’s work and lecturing on the stretch cycling cycle. The fifth Annual Global Hamstring Project in Barcelona, November 16 & 17, is in honor of great Paavo Komi.
