NAKAMURA, Fábio Yuzo et al. Relationship between physiological indicators obtained in ergospirometry test in cycle ergometer of upper extremities and performance in canoeing. Rev Bras Med Esporte [online]. 2007, vol.13, n.5, pp.283-286. ISSN 1517-8692. http://dx.doi.org/10.1590/S1517-86922007000500001.
Evaluation of aerobic fitness indicators in canoers reveals functional characteristics acquired through specific training, which can be related to competitive performance. Thus, the aim of the present study was to evaluate functional evaluators obtained in ergospirometry test of young canoers, as well as to verify the relationship of these variables with performance in 200, 500 and 1000 m distances. The sample consisted of 12 male athletes (17.6 ± 2.1 years; 175.7 ± 2.5 cm; 68.3 ± 6.3 kg) through a test in cycle ergometer of upper extremities for determination of oxygen uptake in the ventilatory threshold 1 (VT1 - 1.8 ± 0.4 L/min), in the ventilatory threshold 2 (VT2 - 2.9 ± 0.4 L/min) and VO2peak (3.5 ± 0.4 L/min). The test began with a 17 W load, with 17 W/min increments until voluntary exhaustion. The athletes have been also submitted to specific tests in K-1 individual canoe in a lake, with the purpose to reach the lowest times in the referred distances (times equivalent to 47.6 ± 4.3, 122.0 ± 9.0 and 239.5 ± 12.6 s, respectively). The Spearman-Rank correlation test was used (rs), with significance level set at 5%. Moderate correlation was observed between VT2 and time in the 1000 m (rs = -0.685), VO2peak and time in the 500 m (rs = -0.699) and VO2peak and time in the 1000 m) rs = -0.734). Therefore, it is concluded that VT2 and VO2peak obtained in cycle ergometer of upper extremities, and expressed in absolute terms, predict performance in 500 and 1000 m canoeing events and can be potentially applied in evaluation of canoers.
