Abstract:
:Our purpose was to demonstrate that 30-s tethered swimming test can be a useful tool to estimate swimming performance in short distance freestyle events. Thirteen high level adolescent swimmers (7 male and 6 female of 16.6 ± 1.0 and 15.8 ± 0.8 years old) performed a 30-s maximum effort in front crawl tethered swimming. Afterward, subjects completed 50-m and 100-m freestyle events at the National Championships. Both maximum and mean force values obtained in the tethered test related directly with 50-m (r = .78 and r = .72, p < .01, respectively) and 100-m freestyle velocities (r = .63 and r = .61, p < .05, respectively). Fatigue index did not present a significant relationship with any of the studied performance variables. However, a proposed parameter--fatigue slope-correlated with 50-m (r = -.75, p < .01), 100-m performances (r = -.57, p < .05) and with r[La-] (r = -.90, p < .01). It is concluded that, for adolescent swimmers, values obtained from 30-s tethered test are well related with swimming performance in sprint events. In addition, fatigue slope seems to be more associated with swimming performance in short distance events than fatigue index.
