Seventeen elite male taekwondo athletes (age: 17.59 \u00b1 4.34 years; body height: 1.72 \u00b1 6.5 m; body mass: 61.3 \u00b1 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 &lt; 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 \u00b1 6.4 ml\/kg\/min and 52.6 \u00b1 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.<\/jats:p>","DOI":"10.1515\/hukin-2016-0016","type":"journal-article","created":{"date-parts":[[2016,10,21]],"date-time":"2016-10-21T10:00:51Z","timestamp":1477044051000},"page":"117-126","source":"Crossref","is-referenced-by-count":10,"title":["Determination of Aerobic Power Through a Specific Test for Taekwondo - A Predictive Equation Model"],"prefix":"10.1515","volume":"53","author":[{"given":"Fernando P.S.","family":"Rocha","sequence":"first","affiliation":[{"name":"Department of Sports Sciences, University of Beira Interior, Portugal"},{"name":"Research Center for Sport, Health and Human Development (CIDESD), Portugal"}]},{"given":"Hugo","family":"Louro","sequence":"additional","affiliation":[{"name":"Research Center for Sport, Health and Human Development (CIDESD), Portugal"},{"name":"Sports Sciences School of Rio Maior, Polytechnique Institute of Santar\u00e9m, Portugal"}]},{"given":"Ricardo","family":"Matias","sequence":"additional","affiliation":[{"name":"School of Healthcare, Set\u00fabal Polytechnic Institute, Portugal"},{"name":"Lisbon University, Faculty of Human Kinetics, Neuromechanics Research Group- Interdisciplinary Centre for Study of Human Performance (CIPER), LBMDF, Portugal"}]},{"given":"Jo\u00e3o","family":"Brito","sequence":"additional","affiliation":[{"name":"Research Center for Sport, Health and Human Development (CIDESD), Portugal"},{"name":"Sports Sciences School of Rio Maior, Polytechnique Institute of Santar\u00e9m, Portugal"}]},{"given":"Aldo M.","family":"Costa","sequence":"additional","affiliation":[{"name":"Department of Sports Sciences, University of Beira Interior, Portugal"},{"name":"Research Center for Sport, Health and Human Development (CIDESD), Portugal"},{"name":"CICS-UBI Health Sciences Investigation Center, University of Beira Interior"}]}],"member":"374","published-online":{"date-parts":[[2016,10,14]]},"reference":[{"key":"2021040801180685319_j_hukin-2016-0016_ref_1_w2aab3b8c61b1b7b1ab2b1b1Aa","doi-asserted-by":"crossref","unstructured":"Aisbett B, Le Rossignol P.
