Research on Lower Limb Motion Characteristics of Oblique Stride on “Euro Step” Layup Based on Intelligent Motion Capture System

In recent years, intelligent motion capture system has been widely used in sports research and training guidance. This study used biomechanical methods, and combined with sports engineering equipment. Surface EMG Tester Delsys, Infrared Spot High-speed Motion Capture Test System Motion and Dynamometer Kistler were utilized to collect the biomechanical data of the first-class basketball players’ “Euro Step” movement synchronously, and quantitative analysis was emphatically carried out on the oblique stride. The research shows that the muscle activation and recruitment degree on one side of the pedal leg in the “Euro Step” layup is stronger than that on the other side; the joint angle of the knee and ankle joints changes greatly. In this action, the plantar exerts force obviously in the horizontal direction. It is suggested that athletes should exercise gastrocnemius muscles in a targeted way to strengthen their pedaling and stretching ability; it is needed for athletes to enhance the strength of the gluteus maximus and biceps femoris and the extensibility of muscles at the hip joint to improve the stability of movement; it is imperative to raise the endurance of tibialis anterior muscle to prevent the corresponding injuries caused by sports fatigue; athletes ought to strengthen strength training of knees and ankles or wear protective gear to prevent joint sprain.
