The purpose of this study was to examine the effects on sprint swimming performance after low- and high-intensity active recovery (AR) as compared to passive recovery. Ten male competitive swimmers (age: 17.9 ± 2.3 years; body mass: 73.2 ± 4.0 kg; height: 1.81 ± 0.04 m, 100-m best time: 54.90 ± 1.96 seconds) performed 8 × 25-m sprints with 120-second rest intervals followed by a 50-m sprint 6 minutes later. During the 120-second and the 6-minute interval periods swimmers rested passively (PAS) or swam at an intensity of 40% (ACT40; 36 ± 8% of the V(O2)max) and 60% (ACT60; 59 ± 7% of the V(O2)max) of their individual 100-m velocity. Performance time of the 8 × 25-m after ACT60 was slower compared with PAS and ACT40, but no difference was observed between ACT40 and PAS conditions (PAS: 12.15 ± 0.48, ACT40: 12.23 ± 0.54, ACT60: 12.35 ± 0.57 seconds, p < 0.05). Performance time of the 50-m sprint was no different between conditions (PAS: 26.45 ± 0.91; ACT40: 26.30 ± 1.18; ACT60: 26.21 ± 1.19 seconds; p > 0.05). Blood lactate concentration was not different between PAS, ACT40, and ACT60 after the 8 × 25-m and the 50-m sprints (p > 0.05). Passive recovery, or low intensity of AR (40% of the 100-m velocity), is advised to maintain repeated 25-m sprint swimming performance when a 2-minute interval period is provided. Active recovery at an intensity corresponding to 60% of the 100-m velocity decreases performance during the 25-m repeated sprints without affecting the performance time on a subsequent longer duration sprint (i.e., 50 m).
本研究旨在比较低强度和高强度主动恢复（AR）对短跑游泳表现的影响。10 名男性竞技游泳运动员（年龄：17.9±2.3 岁；体重：73.2±4.0 公斤；身高：1.81±0.04 米，100 米最佳时间：54.90±1.96 秒）进行了 8×25 米冲刺，每组间隔 120 秒，之后 6 分钟后进行 50 米冲刺。在 120 秒和 6 分钟的间隔期间，游泳者被动休息（PAS）或以 40%（ACT40；个体 100 米速度的 36±8%）和 60%（ACT60；个体 100 米速度的 59±7%）的强度游泳。与 PAS 和 ACT40 相比，ACT60 后 8×25 米的表现时间较慢，但 ACT40 和 PAS 条件之间没有差异（PAS：12.15±0.48，ACT40：12.23±0.54，ACT60：12.35±0.57 秒，p<0.05）。50 米冲刺的表现时间在条件之间没有差异（PAS：26.45±0.91；ACT40：26.30±1.18；ACT60：26.21±1.19 秒；p>0.05）。8×25 米和 50 米冲刺后，PAS、ACT40 和 ACT60 之间的血乳酸浓度没有差异（p>0.05）。当提供 2 分钟间隔时，建议进行被动恢复或低强度的 AR（个体 100 米速度的 40%），以维持重复 25 米冲刺的游泳表现。以相当于个体 100 米速度的 60%的强度进行主动恢复会降低 25 米重复冲刺的表现，而不会影响随后较长时间冲刺（即 50 米）的表现时间。
