The study of fatigue during training is becoming a very useful tool to avoid possible injuries not only during the training sessions but also during recovery time. Many researches have proved that concepts such as muscular fatigue and postactivation potentiation have a close relationship. With this aim, vertical jump can provide a very important information that can help to analyze the muscular fatigue that happened during this type of activity, mainly if the monitoring system is able to measure jumping parameters during their regular training session in their natural training environment. This study was performed with instrumented insoles called ECnsole. These insoles were tested with a group of twelve volunteers. In a tumbling surface, the participants performed a jumping protocol in three conditions: rest, fatigue-induced, and recovery. Using these validated insoles, the acrobatic gymnasts showed an inability to use the stretch-shortening cycle for improving vertical jumping performance after fatigue condition, although no deterioration of jump performance was found.

肌肉疲劳对杂技体操运动员垂直跳跃性能的急性影响，通过仪器鞋垫评估：一项初步研究

在训练过程中进行疲劳研究已成为一种非常有用的工具，不仅可以避免在训练过程中而且在恢复期间也可能造成伤害。许多研究证明，诸如肌肉疲劳和激活后增强等概念有着密切的关系。出于这个目的，垂直跳动可以提供非常重要的信息，可以帮助分析在这种类型的活动中发生的肌肉疲劳，主要是监视系统能够在其自然训练环境中的常规训练过程中测量跳动参数。这项研究是使用称为ECnsole的仪器化鞋垫进行的。这些鞋垫由一组十二名志愿者进行了测试。在翻滚的地面上，参与者在以下三种情况下执行了跳跃动作：休息，疲劳诱发和恢复。
