الملخص

The purpose of this study is to investigate the relationship between elbow angles  of the body and pole vault performance and to explore an effective method for improving pole vault performance. The study selected 14  male athletes and 14 female  athletes to jump  to perform pole vault. They participated in the local championship of the competition, field and track . The researcher analyzed the best performance in the competition. The camera used for this study was Sony type(HDR cx-200). The camera frequency was 60 frames  per second of Video Quality HD. The video camera was installed on a tripod at a vertical height of 1.50 meters from  pole vault and at a distance of 25 m to picture activity of  pole vault. The collected and analyzed data were transformed  by Dartfish program . Angle of elbow (angle between elbow and upper arm) at the moment of rise. These data were analyzed statistically by the linear regression method using the statistical program (Minitab 17). The performance is set as an independent  variable. Elbow angle is set as a dependent variable to verify that each factor is different. The α level is set to 0.05. The elbow angle can estimate the best performance factor with 80.01%. So we can expect that if  the Polish athletes make the elbow angle wide during the pole vaulting, it will increase their performance.
