Research on Predicting Trunk Isometric Strength with Core Stability Related Measurements

Choose from 5 types of isometric strength (TIS) test, trunk extensor endurance (EE) test, trunk flexion and extension range (TFE) test, dominant single-leg standing (DLS) test and dominant single-leg long jump (DLH) The test items reflect the strength, endurance, flexibility, balance and functionality of the core stability (CS). Pearson correlation analysis and multiple linear regression analysis were performed on the relationship between the four core stability related tests and TIS. The results showed that TFE has a significant negative correlation with A 60 , A 90 , A 120 and T 120 , and DLH has a significant correlation with A 60 , T60, A 90 , T 90 , A 120 and T 120 . Tip: TFE and DLH are effective indicators for predicting TIS. The shared variability of TFE, DLH and TIS is specific to the position of the link; core strength training should pay special attention to the position relationship between the sports links to improve training efficiency.
