INTRODUCTION AND PURPOSE Angles of left/right cycling pedals and curving handles, momentary strength alterations of vertical/horizontal striking and other relevant indexes such as compound forces, necessary forces, and their efficiencies were recorded for a total of 70 cyclists on a special training treadmill for cycling. Combined with physiological properties of pedal ankles in circular exercises, statistical analysis of sports mechanics was applied to gain an available and quantitative scheme for cycling treading with a brand-new circular indication. i. RESULTS Statistical analysis showed that the key result of cycling treading depended on efficiency. The degree of efficiency relied on pedal angles in case the forces imposed were certain. CONCLUSIONS A new consideration about "dead point" was also drawn up. At the same time a new point of view was put forward towards the concept of "dead point". "Dead point" was the point at which the compound forces were Zero instead of the point without forces. Up/down “dead point” emerged uncertainly.
