To compare the posttraining recovery timeline of elite Brazilian futsal athletes before (Pre-PS) and after 10 weeks of the preseason (Post-PS) period of high-intensity technical-tactical training.
At the start (n = 13) and at the end of the preseason (n = 7), under-20 male futsal players undertook fitness testing for maximal aerobic power, the countermovement jump (CMJ), and the 10-m sprint with change of direction. Furthermore, at both Pre-PS and Post-PS, the players participated in a training session where performance and psychophysiological measures were recorded before, immediately, 3, 24, and 48 hours postsession. The measures included CMJ, 10-m sprint, creatine kinase, Total Quality Recovery Scale, and Brunel Mood Scale. Effect size (ES) analyses compared fitness and posttraining recovery values for each parameter at Pre-PS versus Post-PS.
Only trivial ES (-0.02 to 0.11) was evident in maximal aerobic power, CMJ, and 10-m sprint at Post-PS compared with Pre-PS. For the timeline of recovery, only trivial and small ESs were evident for the 10-m sprint (-0.12 to 0.49), though CMJ recovery was improved at 3 hours (0.87) and 48 hours (1.27) at Post-PS and creatine kinase was lower at 48 hours (-1.33) at Post-PS. Perception of recovery was improved in Post-PS at 3 hours (1.50) and 24 hours postsession (0.92). Furthermore, perception of effort was lower immediately after the session (-0.29), fatigue was lower at 3 hours (-0.63), and vigor responses were improved in all postseason assessments (0.59 to 1.13).
Despite minimal changes in fitness, preseason training attenuated players' perception of effort and fatigue and improved their recovery profile following a high-intensity technical-tactical training session.
比较精英巴西五人制足球运动员在高强度技术战术训练的 preseason（Pre-PS）前（Pre-PS）和 10 周后的posttraining 恢复时间线。
在 preseason开始时（n = 13）和结束时（n = 7），20 岁以下的男子五人制足球运动员接受了最大有氧能力、反跳（CMJ）和 10 米变向冲刺的体能测试。此外，在 Pre-PS 和 Post-PS 时，球员们参加了一个训练课程，在课前、课后立即、3 小时、24 小时和 48 小时记录了表现和心理生理测量值。测量值包括 CMJ、10 米冲刺、肌酸激酶、总质量恢复量表和布鲁内尔情绪量表。效应大小（ES）分析比较了 Pre-PS 和 Post-PS 每个参数的体能和训练后恢复值。
与 Pre-PS 相比，Post-PS 仅显示出极小的 ES（-0.02 至 0.11）在最大有氧能力、CMJ 和 10 米冲刺方面。对于恢复时间线，只有微小和小的 ES 在 10 米冲刺中是明显的（-0.12 至 0.49），虽然在 Post-PS 时，CMJ 的恢复在 3 小时（0.87）和 48 小时（1.27）得到改善，而肌酸激酶在 Post-PS 时在 48 小时（-1.33）时降低。在 Post-PS 时，在课后 3 小时（1.50）和 24 小时（0.92）时恢复的感觉得到改善。此外，在课后立即，感知到的努力降低（-0.29），疲劳在 3 小时（-0.63）时降低，在所有季后评估中，活力反应得到改善（0.59 至 1.13）。
尽管体能变化不大，但 preseason 训练减轻了运动员对努力和疲劳的感知，并改善了他们在高强度技术战术训练课后的恢复情况。
