fNIRS data

For the data collection, subjects first performed a baseline Stroop test, followed by three different sessions in randomized order: a) control (resting in a seated position); b) Tai Chi (24 simplified Yang style or 28 simplified Chen style moves), and c) brisk walking (Figure 1). In the control session, subjects rested for 11 minutes. In the exercise sessions, subjects performed brisk walking (5.6 km/h) on the treadmill or Tai Chi for about 6 min, followed by a 5-minute rest. The heart rate (HR) was monitored during exercise and rest. Raw data are fNIRS data collected during stroop tests. Each subject has 4 files，named as baseline, control, TC (Tai Chi), and BW (brisk walking).

本次数据采集流程如下：受试者首先完成基线版斯特鲁普（Stroop）测试，随后按随机顺序开展三项不同任务环节：a）对照环节（保持安静坐姿休息）；b）太极拳练习环节（24式简化杨氏太极拳或28式简化陈氏太极拳）；c）快走运动环节（详见图1）。在对照环节中，受试者需静坐休息11分钟。在运动环节中，受试者或在跑步机上以5.6 km/h的速度快走，或练习太极拳约6分钟，随后进行5分钟的休息。运动及休息期间均对受试者的心率（HR）进行持续监测。本次采集的原始数据为斯特鲁普测试期间获取的功能性近红外光谱（fNIRS）数据。每位受试者对应4个数据文件，分别命名为baseline、control、TC（太极拳）以及BW（快走）。
