EFFECTS OF RAPID STRETCHING ON EXPLOSIVE POWER OF THE LOWER EXTREMITY IN LONG JUMP ATHLETES

Abstract

Introduction: The long jump is characterized by a high degree of combination of speed and strength. It belongs to the group of fast power items dominated by physical conditioning. To achieve good results in long jump, it is necessary to have good physical conditioning. Objective: In order to explore the effect of compound fast stretch training on the explosive power of lower limbs of athletes in long jump. Methods: Athletes from a certain city were selected as the research objects of the experiment, with a total of 100 people, and were divided into groups by random drawing, there were 50 people in the control group and 50 people in the experimental group, who received rapid stretching compound training. Results: After collecting the independent samples, statistical analysis was performed with T-test, the results showed confidence of P=0.09, higher than 0.05, indicating that there is no significant difference in the special performance of long jump between the two groups of students, the mean score of students in the experimental group was 0.13 meters higher than the control group. Conclusions: Rapid training composed of relaxation and contraction can effectively improve the special quality in long jump students.
