Need to apply life-cycle asset management approaches to enhance sports engineering. Like infrastructure, the human body has an 80-year+ life-span - which is why we go to the dentist and have regular check-ups. Preventive maintenance, proservation techniques, life-cycle value engineering can all play into the sports engineering field. Sports engineering has the $$$ incentive to produce great results in longevity of life spans. Look how the results of war have contributed to human reconstruction. Sports madicen can also benefit from sports engineering - consider the extension to robotics.
