|Abstract: ||Res:Warming up before physical activity is usual and became assumed as essential in competition
and training events. It is expected an optimization in performance but the literature
is still ambiguous on this subject. The aim of this study was to assess the effect
of the regular warm-up in 50 m swimming performance, in female swimmers. Seven
national-level swimmers (mean ± SD; age 15.3 ± 1.1 years-old, height: 1.61 ± 8.1 m,
body mass: 56.5 ± 7.0 kg) volunteered for this study. Each swimmer performed 50 m
freestyle at the maximum velocity, after previous warm-up and without performing
the same, with 24 h between conditions. Times were registered and capillary blood
lactate concentration was assessed after the swimming trial at the 1st and 3rd min of
recovery. Additionally, the Borg ratings of perceived exertion scale were used and biomechanical
parameters such as stroke frequency, stroke length and stroke index were
assessed. The 50 m swimming times were not different with and without warm-up
(33.05 ± 2.34 s and 32.71 ± 2.07 s, respectively, p =.40). No differences were found
in lactate values (8.63 ± 1.49 mmol·l-1 and 7.93 ± 1.92 mmol·l-1, respectively; p = .71),
ratings of perceived exertion (15.86 ± 1.07 and 15.14 ± 1.22, respectively; p =.24),
stroke frequency (0.81 ± 0.08 Hz and 0.81 ± 0.04 Hz, respectively; p = .79), stroke
length (1.87 ± 0.14 m and 1.89 ± 0.12 m, respectively; p = .74) and stroke index (2.85 ±
0.31 m2 c-1 s-1 and 2.91 ± 0.34 m2 c-1 s-1, respectively; p = .40). These results suggested
that regular warm-up used by the swimmers does not influence the 50 m freestyle
performance, in female swimmers.|
