چکیده    Considering the need of most sports skills to perform fast actions, change of direction at an appropriate time, and necessity utilization of suitable agility tests for assessment, the purpose of this study was to determine the validity and reliability of the “chaboki afza” researcher-made device. in this experimental research, the model of the study was validation and reliability, and classified in applied research type. following the design and construction of the agility booster device, for its validity and reliability, 10 young healthy volunteering to participate in this study. all tests were executed in the same conditions on both t and illinois tests instruments and reference tests, by two examiners. to evaluate the validity of the researcher-made device, independent t-test was applied on the data recorded from the device-related test and the recorded data from the functional tests. furthermore, to evaluate the reliability of instrument, the inter-intra class correlations (icc) were used. research results showed a significant correlation coefficient between the device test in all three replicates of the device and the illinois field test (r = 0.66). while there was no significant correlation between t-test and the proposed instrument’s tests (r = 0.23). the achieved results confirmed acceptable reliability of tests (within the examiner for consecutive repetitions of 0.93, 0.72 and 0.69, respectively and between the examiners 0.96) for inter-intra class correlation in these research measurements. due to the results, chaboki afza can be recommended as an alternative or complementary device for evaluating agility field tests.
