Abstract

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 ((V)over dotO(2) peak), maximal heart rate (HRmax), peak blood lactate concentration {[}La-peak], 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: (V)over dotO(2) peak 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 {[}60] s) and {[}La-peak] (7.10 {[}1.76] mmol.L-1) in the UKtest were different (P < .05) from UBtest (416 {[}47] s, 9.93 {[}2.15] mmol.L-1, respectively) and LBtest (433 {[}54]s, 10.29 {[}2.23] mmol.L-1, respectively). Very large relationships between (V)over dotO(2) peak in UKtest with UBtest (r = .78; P = .003) and LBtest (r = .87; P < .001) were found. Maximal values were achieved for the UKtest (V)over dotO(2) peak, HRmax, {[}La-peak], RPE, and maximal aerobic speed, with no difference between test and retest (P > .05). In addition, very large intraclass correlation coefficients (ICC) for (V)over dotO(2) peak (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. (AU)
