Abstract(s)
Our aim was to verify the concurrent validity of a maximal taekwondo specific test (TST) to predict VO2max
through an explanatory model. Seventeen elite male taekwondo athletes (age: 17.59 ± 4.34 years; body height: 1.72 ± 6.5
m; body mass: 61.3 ± 8.7 kg) performed two graded maximal exercise tests on different days: a 20 m multistage shuttle
run test (SRT) and an incremental TST. We recorded test time, VO2max, ventilation, a heart rate and time to
exhaustion. Significant differences were found between observed and estimated VO2max values [F (2, 16) = 5.77, p <
0.01]; post-hoc subgroup analysis revealed the existence of significant differences (p = 0.04) between the estimated
VO2max value in the SRT and the observed value recorded in the TST (58.4 ± 6.4 ml/kg/min and 52.6 ± 5.2 ml/kg/min,
respectively). Our analysis also revealed a moderate correlation between both testing protocols regarding VO2max (r =
0.70; p = 0.005), test time (r = 0.77; p = 0.02) and ventilation (r = 0.69; p = 0.03). There was no proportional bias in the
mean difference (t = -1.04; p = 0.313), and there was a level of agreement between both tests. An equation/model was
used to estimate VO2max during the TST based on the mean heart rate, test time, body height and mass, which
explained 74.3% of the observed VO2max variability. A moderate correlation was found between the observed and
predicted VO2max values in the taekwondo TST (r = 0.74, p = 0.001). Our results suggest that an incremental specific
test estimates VO2max of elite taekwondo athletes with acceptable concurrent validity.
