Enhancing recovery is a fundamental component of high-performance sports training since it enables practitioners to potentiate physical performance and minimise the risk of injuries. Using a new sports legging embedded with an intelligent system for electrostimulation, localised heating and compression (completely embodied into the textile structures), we aimed to analyse acute recovery following a fatigue protocol. Surface electromyography- and torque-related variables were recorded on eight recreational athletes. A fatigue protocol conducted in an isokinetic dynamometer allowed us to examine isometric torque and consequent post-exercise acute recovery after using the sports legging. Regarding peak torque, no differences were found between post-fatigue and post-recovery assessments in any variable; however, pre-fatigue registered a 16% greater peak torque when compared with post-fatigue for localised heating and compression recovery methods. Our data are supported by recent meta-analyses indicating that individual recovery methods, such as localised heating, electrostimulation and compression, are not effective to recover from a fatiguing exercise. In fact, none of the recovery methods available through the sports legging tested was effective in acutely recovering the torque values produced isometrically.
促进恢复是高性能运动训练的一个基本组成部分，因为它使从业者能够提高身体表现并最大程度地降低受伤风险。我们使用一种新的带有智能电刺激、局部加热和压缩系统的运动裤（完全融入纺织品结构中），旨在分析疲劳后的急性恢复情况。对八名休闲运动员进行了表面肌电图和扭矩相关变量的记录。在等速测力计中进行的疲劳协议使我们能够检查在使用运动裤后的等长扭矩和随后的运动后急性恢复。关于峰值扭矩，在任何变量中，疲劳后和恢复后评估之间没有差异；然而，与局部加热和压缩恢复方法相比，局部加热和压缩恢复方法的预疲劳记录的峰值扭矩高 16%。我们的数据得到了最近的荟萃分析的支持，这些分析表明，个体恢复方法，如局部加热、电刺激和压缩，对于从疲劳运动中恢复并没有效果。事实上，通过测试的运动裤提供的任何恢复方法都不能有效地急性恢复等长产生的扭矩值。
