Introduction There are some studies concern special field-based tests for wheelchair basketball players however, there were not a lot of studies confirmed reliability and/or validity of wheelchair basketball field-based tests. The aim of the present study was to assess test-retest reliability of the newly developed field-based tests focused on short time efforts with maximal intensity for wheelchair basketball players. Material and methods Nine elite male wheelchair basketball players (mean age 29.7 ± 5.9 years) performed two times 11 field-based tests focused on short time efforts with the maximal intensity: 3 m sprint, 5 m sprint, 10 m sprint, 20 m sprint, pass basketball ball by both hands from the chest, pass medicine ball (3 kg) by both hands from the chest, bilateral handgrip, 3-6-9 m drill test, 30-seconds sprint test, agility drill test, and 10x5 m sprint test. All sprint tests’ time were measured by Microgate® photocells (Bolzano, Italy). Differences between field-based tests repetitions were compared by the t-test for dependent samples, relationship between repetitions was calculated by the Pearson correlation coefficient, and the ICCs were calculated (test-retest reliability). Results The ICCs were ‘very good’, correlations were strong for each field-based test (r > 0.7). Only for the agility drill test the first repetition is statistically different compare to the second repetition (p = .015). Conclusions The main application of our research is a confirmation of reliability of 10 field-based tests related to short time efforts with maximum intensity: 3 m sprint, 5 m sprint, 10 m sprint, 20 m sprint, pass basketball ball by both hands from the chest, pass medicine ball (3 kg) by both hands from the chest, bilateral handgrip, 3-6-9 m drill test, 30-seconds sprint test, and 10x5 m sprint test.
