This study investigated the possible influence of the gender on the responses of swimmers during a taper period (TP).
Ten males (19±3 years and 73.5±7.8 kg) and ten females (17±2 years and 54.7±7.2 kg) swimmers were submitted to a 12-week training, followed by three weeks of the TP. Before and after the TP we evaluated the performance at 100 m freestyle, stroke parameters and lactacidemic responses; lactate minimum intensity (LMI) and stroke parameters associated with LMI and the propulsive force in tethered swimming. TP consisted of 14 sessions with mean volume 2253±1213 m/session at an intensity below than the LMI, 1730±327 m/session at an intensity near the LMI and 1530±1019 m/session at an intensity above the LMI.
Significant effects of the genders were observed for LMI and stroke parameters (P<0.001 and η>0.52 [large]) and propulsive force (P=0.001; η=0.59 [large]). However, no significant effects of the TP were identified in the performance of the 100 m freestyle (P=0.66; η=0.006 [small]), propulsive force (P>0.63; η<0.006 [small]), aerobic parameters (LMI: P=0.32 and η=0.03 [small]) and mechanical parameters (P>0.23; η=0.01 [small]). Nonetheless, the peak blood lactate concentrations were improved after TP (P=0.014; η=0.16 [large]), without significant interactions (P=0.38; η=0.02 [small]), as well as the mechanical parameters during maximum 100 m freestyle (P<0.04 and η>0.10 [medium]).
Hence, men and women presenting significantly different values in the age group studied, the responses observed after the TP investigated were the same independent of gender.
本研究旨在探讨性别对游泳运动员在减量期(TP)反应的可能影响。
10 名男性(19±3 岁,73.5±7.8kg)和 10 名女性(17±2 岁,54.7±7.2kg)游泳运动员进行了 12 周的训练,随后进行了 3 周的 TP。在 TP 前后,我们评估了 100 米自由泳的表现、划水参数和乳酸反应;乳酸最小强度(LMI)以及与 LMI 和在有绳游泳中的推进力相关的划水参数。TP 由 14 次训练组成,每次训练的平均量为 2253±1213m/session,强度低于 LMI,1730±327m/session 接近 LMI,1530±1019m/session 高于 LMI。
性别对 LMI 和划水参数(P<0.001,η>0.52[大])和推进力(P=0.001;η=0.59[大])有显著影响。然而,TP 对 100 米自由泳的表现(P=0.66;η=0.006[小])、推进力(P>0.63;η<0.006[小])、有氧参数(LMI:P=0.32 和 η=0.03[小])和机械参数(P>0.23;η=0.01[小])没有产生显著影响。尽管如此,TP 后峰值血乳酸浓度有所提高(P=0.014;η=0.16[大]),但无显著交互作用(P=0.38;η=0.02[小]),最大 100 米自由泳的机械参数也有所提高(P<0.04,η>0.10[中])。
因此,尽管在研究的年龄组中,男性和女性的数值存在显著差异,但在接受 TP 后观察到的反应不受性别影响。
