Agility as an essential characteristic of many athletic activities, assess with different agility tests. Definitions provided for agility consider it as the ability to start explosively and perform decelerations, change of directions (CODs) and re-accelerations. There is many turns happened during a match-play in football and also the ability of COD while sprinting determined field sport performance.
In this study for the purpose of assessment of agility performance a novel test consist of more CODs than routine agility test established and evaluated.
23 university football team players (179.3±6.9cm, 70±8.3kg, 21.9±3.5yrs) and 21 university football class without any routine exercises players (178.9±6.2cm, 70.2±9.1kg, 20.8±2.1yrs) participated in this study. They performed Illinois and novel agility tests and 30m sprint test. Participant carried a single IMU attached to sacrum for measurement of total acceleration which is used for detection of test duration. Independent t-test and Pearson correlation used for statistical analysis (p<0.05).
Time duration of three tests for both groups measured. In both group novel agility test lasted for longer time than Illinois. P-value of independent t-test for of Illinois and novel agility tests and 30m sprint test were 0.078, 0.009 and 0.000 respectively. Correlation of these tests were also determined for both groups. Significant correlation for team football players were 0.439 (P-value: 0.036) and for other groups were 0.537(P-value: 0.012) between two agility tests. Also, Statistical analysis revealed a significant correlation between duration of sprint and Illinois tests in participant without exercises (0.701(P-value: 0.000)).
Results demonstrate that novel test could differ between two different groups of participants as well as sprint test. However Illinois test results could not show differences of two groups. It seems that novel agility test could better reflect differences of groups because it has more CODs than Illinois agility test. Correlation value of agility tests in both groups shown strong relation of both tests. Also relationship of sprint and Illinois duration in without exercise group means Illinois agility test in this group reflect speed more than COD performances. In conclusion novel test could reflect participant's agility and detect different level of football performance.
