The objective of this study was to verify the effect of active and passive recovery on blood lactate concentration and power performance. Twelve male subjects were submitted to a maximal strength test in the the bench press, a maximal aerobic test in the bench step, and to four sets of bench press exercise performed as fast and as long as possible, using 80% of maximal strength when active or passive recovery was performed. The maximum number of repetitions, mean and peak power in eccentric and concentric phases were computed and blood lactate concentration was measured. Comparisons for the variables were made using a two-way variance analysis (recovery type and set numer) with repeated measures in the second factor. When significant differences were detected (p < 0.05), a Tukey post-hoc test was used. There was a main effect of set number on maximum number of repetitions (p < 0.05) (1 > 2, 3, and 4; 2 > 3 and 4; 3 > 4). Mean and peak power in both eccentric and concentric phases also differed across sets (1 > 2, 3, and 4; 2 > 4). There was also a main effect for the recovery type, with lower values (p < 0.05) observed for the active recovery compared to the passive one. It can be concluded that active recovery resulted in lower lactate concentration, but did not improve power performance in the bench press exercise.
本研究旨在验证主动和被动恢复对血乳酸浓度和力量表现的影响。12 名男性受试者分别进行了卧推最大力量测试、卧推台阶最大有氧测试和 4 组卧推练习,使用 80%的最大力量进行尽可能快和尽可能长的运动,在主动或被动恢复时进行。计算了离心和向心阶段的最大重复次数、平均和峰值功率,测量了血乳酸浓度。使用双向方差分析(恢复类型和组号)和第二因素的重复测量对变量进行比较。当检测到显著差异时(p < 0.05),使用 Tukey 事后检验。组号对最大重复次数有主要影响(p < 0.05)(1 > 2、3 和 4;2 > 3 和 4;3 > 4)。在离心和向心阶段的平均和峰值功率也因组号而异(1 > 2、3 和 4;2 > 4)。恢复类型也有主要影响,与被动恢复相比,主动恢复的乳酸浓度较低(p < 0.05)。可以得出结论,主动恢复可导致较低的乳酸浓度,但不能提高卧推运动的力量表现。
