Purpose: To evaluate criterion validity, reliability, and usefulness of a test to measure maximal aerobic power using judo-specific movements (uchi-komi test [UKtest]). Methods: A total of 12 judokas performed 5 graded exercise tests (GETs) in 4 sessions. In sessions 1 and 2, upper-body (UBtest), lower-body (LBtest), and familiarization UKtest were performed. GETs were randomly performed and separated by at least 48 h. In sessions 3 and 4, test and retest UKtest were performed (7 d apart). For all GETs, peak oxygen consumption (), maximal heart rate (HRmax), peak blood lactate concentration [Lapeak], maximal aerobic intensity, and rating of perceived exertion (RPE) were determined. Another group of 12 judokas performed the UKtest and 1 confirmation test (20 min after the UKtest) at 105% of maximal aerobic speed until exhaustion to confirm whether maximal responses were achieved. Results: did not differ (P > .05) between UKtest (46.04 [5.34] mL·kg−1·min−1) and LBtest (44.78 [5.98] mL·kg−1·min−1), but it was higher (P < .05) than UBtest (37.03 [7.16] mL·kg−1·min−1). Total duration (551  s) and [Lapeak] (7.10 [1.76] mmol·L−1) in the UKtest were different (P < .05) from UBtest (416  s, 9.93 [2.15] mmol·L−1, respectively) and LBtest (433  s, 10.29 [2.23] mmol·L−1, respectively). Very large relationships between in UKtest with UBtest (r = .78; P = .003) and LBtest (r = .87; P < .001) were found. Maximal values were achieved for the UKtest, HRmax, [Lapeak], RPE, and maximal aerobic speed, with no difference between test and retest (P > .05). In addition, very large intraclass correlation coefficients (ICC) for (ICC = .86), HRmax (ICC = .90), and maximal aerobic speed (ICC = .81) were found. Conclusion: The UKtest can be considered a valid, reliable, and useful test to measure maximal aerobic power using judo-specific movements.
