目的：观察在游泳池和水槽条件下使用潜水衣与泳衣引起的性能，生理和一般运动学变量的变化。研究方法：在一个随机和平衡的顺序，33名游泳运动员（26.46 [11.72]岁）进行2 × 400米的最大前爬泳在一个25米的游泳池（与潜水服和泳衣），他们的平均速度在2个游泳水槽试验后，与两套。评估速度、血乳酸浓度、心率（HR）、博格量表（主观用力评分）、每搏率、每搏长度（SL）、每搏指数和推进效率。结果如下：在游泳池中，使用潜水衣的400米成绩比使用泳衣的快0.07 m.s（-1），表明所用时间减少了6%（P < .001）。使用两种泳衣时，最大心率、最大血乳酸浓度、感知用力等级、划水率和推进效率相似，但在游泳池和游泳水槽中，潜水服的SL和划水指数均显示出更高的值。在水槽中游泳的最大心率和最大血乳酸浓度低于在游泳池中游泳的两种泳衣，SL，冲程指数和推进效率高于在游泳池中游泳的两种泳衣。结论：6%的速度改善是SL增加4%的结果。游泳者减少了划水率，增加了SL，以受益于潜水服的水动力减少，并提高他们的游泳效率。在训练季节可以使用潜水衣来提高游泳时的适应能力。
Purpose: To observe changes in performance, physiological, and general kinematic variables induced by the use of wetsuits vs swimsuits in both swimming-pool and swimming-flume conditions. Methods: In a randomized and counterbalanced order, 33 swimmers (26.46 [11.72] y old) performed 2 x 400-m maximal front crawl in a 25-m swimming pool (with wetsuit and swimsuit), and their mean velocities were used later in 2 swimming-flume trials with both suits. Velocity, blood lactate concentration, heart rate (HR), Borg scale (rating of perceived exertion), stroke rate, stroke length (SL), stroke index, and propelling efficiency were evaluated. Results: The 400-m performance in the swimming pool was 0.07 m.s(-1) faster when using the wetsuit than when using the swimsuit, evidencing a reduction of similar to 6% in time elapsed (P < .001). Maximal HR, maximal blood lactate concentration, rating of perceived exertion, stroke rate, and propelling efficiency were similar when using both swimsuits, but SL and stroke index presented higher values with the wetsuit in both the swimming pool and the swimming flume. Comparing swimming conditions, maximal HR and maximal blood lactate concentration were lower, and SL, stroke index, and propelling efficiency were higher when swimming in the flume than when swimming in the pool with both suits. Conclusions: The 6% velocity improvement was the result of an increase of 4% in SL. Swimmers reduced stroke rate and increased SL to benefit from the hydrodynamic reduction of the wetsuit and increase their swimming efficiency. Wetsuits might be utilized during training seasons to improve adaptations while swimming.
