PAPOTI, Marcelo; ZAGATTO, Alessandro M.; MENDES, Olga C.  and  GOBATTO, Claudio A.. Use of invasive and non-invasive protocol tests on aerobic and anaerobic performances prediction in Brazilian swimmers. Rev. Port. Cien. Desp. [online]. 2005, vol.5, n.1, pp.07-14. ISSN 1645-0523.

The purpose of this study was to compare the critical velocity (VC) with the anaerobic threshold (LAN) and verify the relationship among VC and LAN with anaerobic swimming capacity (CTA) with the swimmer’s performance in the 15m, 25m, 50m, 100m, 200m, 400m distances in crawl swimming. Eight national level swimmers were volunteers in the present study, and performed 3 progressive efforts of 400m crawl swimming (85%, 90% and 100%) for LAN determination. They also performed the maximum effort in the 15m, 25m, 50m, 100m, 200m and 400m distances in crawl style. The scores resulted from the 200m and 400m distances were submitted to the linear regression procedure for VC determination (angular coefficient) and CTA (linear coefficient). The VC (1.38 ± 0.07) was not significantly different from the LAN (1.37 ± 0.05) and presented significant correlations with the 400m crawl swimming performance (p<0.05), while the CTA did not correlate significantly with any of these swimming performances. In this way, it is possible to conclude that the VC is a trustful reliable indicator for the evaluation of the aerobic capacity in swimming. However, the CTA resulted from y-intercept was not a good predictor of the swimmer’s performance in the distances from 15m to 400m crawl swimming.
