The Biomechanics Analysis Of Basketball Driving With Ball Technical Movement

This paper uses the means and methods of sports biomechanics, and adopts AmericanAPAS motion image analyzing systems and three-dimensional force platform so as to analyzethe movement of breakthrough technology of the CUBS basketball players in NortheastNormal University. From the perspective of kinematics and dynamics, this paper aims toanalyze the movement that may leads to injury when players use it and gives us a deeperunderstanding of its essence. The author hopes to make up the shortage of perception andprovide theoretical support for athletes to improve technical skills, enhance self-protectionawareness and to extend the span of sport life as well as sets light on the future investigations.The main conclusions are:1. From the point of time, the average time of sequential-step breakthrough in the stageof kicking the ball to break is0.45s, the average time of cross-step breakthrough is0.54s; it is0.49s in swivel exploration stage, and it’s0.53s in cross-step breakthrough. So cross-stepbreakthrough is less abrupt, and slower.2. On the ready stance, the non-pivot foot step is more flexible in sequential-stepbreakthrough, and the cross-step breakthrough is relatively fixed.3. After startup, the gravity center of cross-step breakthrough is not obvious thansequential-step breakthrough which greatly reduces. While the cross-step breakthrough ismore stable, and the height of gravity arises later.4.Once initiating, the first step the non-pivot foot strides covers a longer distance and thegravity center propels further in the approach of cross-step breakthrough than thesequential-step breakthrough.5.In the initiating phase, while the pivot-foot serves as the major mechanism of drivingforce in the sequential-step breakthrough technique, rather than the non-pivot one, the bothfeet involved in the other technique burst force actively and share equivalent peak of strength.6.In either way, the peak of strength accumulated in the process that the non-pivot footstamps on the ground after initiating (the strength here ranges from1.2to2.4times of bodyweight) is larger than those accumulated in both pivot and non-pivot feet when initiating.7. When the non-pivot foot take the first step to land, sequential-step breakthrough ismore likely to cause ankle get injured if the the force is the same.8. From the direction of axis X which is the direction of the force on the side, the risk offurther injury of sequential-step breakthrough is larger than that of cross-step breakthrough.
