Sport equipment plays a key role for the performance in all kinds of sports games. Sport competition is not only the skill competitions among athletes and coaches but also the design competitions among the equipment companies. The basic principles of sport science and biomechanics should be applied in sport equipment innovation.The new equipment which enhance muscle strength and explosive power come out one after another. In the recent years, more and more biomechanics theories were applied in the strength training equipment. A new developed training method is demonstrated in this paper. Passive leg press training was developed based on the concepts of the stretch-shortening cycle and the benefits of high muscle contractionvelocity. Thus, these muscle groups accomplished both concentric and eccentric isokinetic contractions in a passive, rapid, and repetitive manner. The results suggest that jump performance, speed, and muscle power significantly improved after PLP training. Applying biomechanics for sporting goods innovation is a promising approach to integrate academic research and industrial which can increase industrial competitiveness and open more doors for biomechanics research.
