The purpose of this study is to relate 200 m front crawl performance (DES) and kinetics variables obtained from a tethered swimming test (TNE): total impulse (IMP), impulse rate (TIMP) and force peak (PF). From 12 competitive swimmers (mean age: 18.3 ± 2.9 years) were obtained IMP, TIMP, PF and DES in 200 m front crawl (this last transformed into unit points). Regarding to DES (711.8 ± 29.1 points): IMP (2663.6 ± 150.6 N·s) was significantly correlated (r = 0.876; p < 0.001), whereas TIMP (-24.45 ± 14.38 N) and PF (217.48 ± 29.1 N) were not correlated (r = -0.553; p = 0.062 and r = -0.19; p = 0.714, respectively). Total impulse obtained from TNE can be used a force capacity along time assessment parameter and as a performance parameter predictor for the 200 m freestyle event.
