论文摘要
强烈锻炼后的身体恢复的实际确定是一个具有挑战性的话题，必须包括机械方面和认知方面，因为大多数体育活动以及专业活动（包括大脑计算机界面接口的系统）都需要良好的形状。本文介绍了20个健康主题的新在线手写数据库。主要目标是研究几种体育锻炼在不同手写任务中的影响，并在剧烈运动后评估恢复。为此，他们在体育锻炼之前和之后执行了不同的手写任务，以及其他测量值，例如代谢和机械疲劳评估。实验结果表明，尽管发生了快速的机械恢复，并且可以通过乳酸浓度和机械疲劳来衡量，但是当需要认知努力时，情况并非如此。手写分析表明，即使在乳酸浓度和机械评估恢复后，手写性能也存在统计差异。结论：这指出了比以经典方式衡量的运动和专业活动的恢复时间的必要性。
Practical determination of physical recovery after intense exercise is a challenging topic that must include mechanical aspects as well as cognitive ones because most of physical sport activities, as well as professional activities (including brain computer interface-operated systems), require good shape in both of them. This paper presents a new online handwritten database of 20 healthy subjects. The main goal was to study the influence of several physical exercise stimuli in different handwritten tasks and to evaluate the recovery after strenuous exercise. To this aim, they performed different handwritten tasks before and after physical exercise as well as other measurements such as metabolic and mechanical fatigue assessment. Experimental results showed that although a fast mechanical recovery happens and can be measured by lactate concentrations and mechanical fatigue, this is not the case when cognitive effort is required. Handwriting analysis revealed that statistical differences exist on handwriting performance even after lactate concentration and mechanical assessment recovery. Conclusions: This points out a necessity of more recovering time in sport and professional activities than those measured in classic ways.
