THE ANALYSIS OF PULLING FORCE CURVES IN TUG-OF-WAR

摘要

The purpose of this study is to analyze the pulling force curves in DFB and AFB movements that produced by elite tug-of-war athletes. The subjects are 11 female high school athletes who have been trained more than two years for tug-of-war. Data is analyzed by paired-sample t-test. The results show that force-related parameters are all different significantly between two movements, and time-related parameters are not significant. The DFB movement has higher value in MaxF, AveF, FS and lower value in MinF. We suggest to avoid the decay of pulling force while adopting DFB movement, and increase MaxF, AveF, and FS while adopting AFB movement. Within the start of 2sec we suggest the team to take the DFB movements in order to produce powerful pulling force, then transform to the AFB movements to keep the team formation.
