Studies On Kinetics Of Foot Action In Basketball Trai Ning

With the continuous development of basketball, people’s enthusiasm to participate in basketball is also growing. In the daily basketball teaching and training, there are many foot-related technical movements which can use the foot to change the purposes of the state of motion, namely to complete sudden stop, fast move and other technical movements. The purpose of this study is to better understand the foot kinetic characteristics in the basketball teaching and training. Significance: researches on the foot kinetic characteristics will help analysis and evaluation of athletic performance and prevention of damages, help improvement of the power generation and stability control of the foot, and help improvement of the buffering capacity of the foot and diagnosis of related diseases. Eventually a foot kinetics database will be formed to provide theoretical guidance and experimental data for the design of functional shoes as well as teaching and training.This study uses the methods such as literature, experiments and mathematical statistics. Through the analysis of the foot dynamics in normal gait(with the left and right feet as the example) and side shuffle(with the right foot as the example) test, this paper studies the foot kinetic characteristics in basketball teaching and training. The subjects were divided into three groups with 20 people in each group, the experimental group, the control group I and the control group II. The experimental test selects RS-footscan force measuring system, and uses SPSS20.0 to analyze the test data. The following results and conclusions were drawn.Analysis:I. In normal gait(with the left and right feet as the example), the following conclusion was drawn after a comparison of the experimental group and the control group I:(1)The time phase in the landing phase, the forefoot contact phase and the lifting phase increases, and the time phase in the whole foot contact phase decreases;(2) As regards to the peak pressure of the foot rub, the pressure in the forefoot area increases, and the pressure in the foot arch and heel area reduces;(3) The peak pressure in the entire region of foot rub increases;(4) The impulse in the entire region of foot rub increases;(5) Foot axial angle increases.II. In side shuffle(with the right foot as the example), the following conclusion was drawn after a comparison of the experimental group and the control group II:(1) The peak pressure in the T1, T2-5, M1, M2, MF, HM and HL areas of the foot rub increases, and the peak pressure in the M3, M4 and M5 areas reduces;(2)The peak pressure in the entire region of foot rub increases;(3)The impulse in the entire region of foot rub reduces.Conclusion:I. Impact of normal gaits on kinetic characteristics in long-term basketball training activities:(1)The lifting phase of the foot rub increases, and the entire foot contact phase decreases;(2) The buffering capacity of the whole foot increases, and the forefoot force increases significantly;(3) The stability of the foot increases. II. Impact of side shuffle on foot kinetic characteristics:(1) The power generation of people being good at basketball is stronger;(2) The buffering capacity of people being good at basketball is better.
