Multimodal Dataset of a 30-Day Yoga Intervention: fNIRS, Biochemical, Postural, and Subjective Outcomes

This dataset accompanies the manuscript Multimodal Assessment of a 30-Day Yoga Intervention: Neural (fNIRS), Biochemical, Postural, and Subjective Outcomes. It contains fNIRS (functional Near-Infrared Spectroscopy) recordings organized by group, time point, and task, including intervention and control folders with pre/post resting-state, breath-hold, and affective image paradigms. Participant metadata, IAPS stimulus-order files, optode MNI (Montreal Neurological Institute) coordinates, protocol documents, and manuscript files are also included. The fNIRS recordings are organized in subject-level nirs folders and stored in SNIRF (Shared Near Infrared File Format) format (Brain Imaging Data Structure BIDS-compatible). The dataset supports analyses of prefrontal hemodynamic responses, resting-state functional connectivity, and intervention-related neural changes in the context of multimodal yoga research. Folder Short description Post_Ctrl_Breath Post-control breath-hold fNIRS subset with 18 recordings across 36 folders, 212 MB.

It includes IAPS-based positive, negative, and neutral stimulus markers, with stimulus order and timing documented in the IAPS CSV file. Pre_Ctrl_RestingState Pre-control resting-state fNIRS subset with 31 recordings across 62 folders, 204 MB. It contains 360 s passive resting-state recordings and no stimulus-related files.

It contains 360 s passive resting-state acquisitions after the 30-day yoga intervention. Pre_Interv_Breath Pre-intervention breath-hold fNIRS subset with 26 recordings across 52 folders, 293 MB. The task consisted of five 20 s breath holds followed by 25–30 s normal-breathing periods. Pre_Interv_Images Pre-intervention affective image-viewing fNIRS subset with 26 recordings across 52 folders, 563 MB. Two presentation sequences were used to reduce habituation, with participant assignments stored in participants.tsv. Pre_Interv_RestingState Pre-intervention resting-state fNIRS subset with 26 recordings across 52 folders, 183 MB. It contains 360 s resting-state recordings before the yoga intervention, with participant metadata and optode localization files provided separately.本数据集配套于学术论文《30天瑜伽干预的多模态评估：神经（fNIRS）、生化、姿势与主观结局》。 本数据集包含按组别、时间节点与任务类型组织的功能近红外光谱（functional Near-Infrared Spectroscopy，fNIRS）记录数据，涵盖干预组与对照组文件夹，内含静息态、屏气任务及情感图片观看范式的前测与后测数据。 数据集同时包含参与者元数据、国际情绪图片系统（International Affective Picture System，IAPS）刺激顺序文件、探头蒙特利尔神经研究所（Montreal Neurological Institute，MNI）坐标、实验方案文档及论文源文件。 功能近红外光谱记录数据按受试者层级组织于nirs文件夹中，以共享近红外文件格式（Shared Near Infrared File Format，SNIRF）存储，且兼容脑成像数据结构（Brain Imaging Data Structure，BIDS）规范。 本数据集可支持多模态瑜伽研究场景下的前额叶血流动力学反应、静息态功能连接及干预相关神经变化分析。 ### 文件夹详情 - **Post_Ctrl_Breath**：对照组后测屏气任务功能近红外光谱子集，涵盖36个文件夹下的18条记录，总大小212 MB。该子集包含标准化的250秒屏气范式，内含5次20秒屏气环节，随后伴随25至30秒的恢复时段。 - **Post_Ctrl_Images**：对照组后测情感图片观看任务功能近红外光谱子集，涵盖36个文件夹下的18条记录，总大小397 MB。刺激标记编码了正性、负性与中性的国际情绪图片系统（IAPS）类别，刺激的时序与标签信息详见IAPS CSV文件。 - **Post_Ctrl_RestingState**：对照组后测静息态功能近红外光谱子集，涵盖36个文件夹下的18条记录，总大小123 MB。该子集包含360秒的被动静息态采集数据，无相关刺激文件。 - **Pre_Ctrl_Breath**：对照组前测屏气任务功能近红外光谱子集，涵盖62个文件夹下的31条记录，总大小294 MB。该任务采用带有引导提示的标准化250秒呼吸调节范式，包含5次屏气循环。 - **Pre_Ctrl_Images**：对照组前测情感图片观看任务功能近红外光谱子集，涵盖62个文件夹下的31条记录，总大小607 MB。该子集包含基于国际情绪图片系统（IAPS）的正性、负性与中性刺激标记，刺激顺序与时序信息详见IAPS CSV文件。 - **Pre_Ctrl_RestingState**：对照组前测静息态功能近红外光谱子集，涵盖62个文件夹下的31条记录，总大小204 MB。该子集包含360秒的被动静息态采集数据，无相关刺激文件。 - **Post_Interv_Breath**：干预组后测屏气任务功能近红外光谱子集，涵盖52个文件夹下的26条记录，总大小272 MB。该任务为标准化250秒屏气范式，由PowerPoint提示引导完成。 - **Post_Interv_Images**：干预组后测情感图片观看任务功能近红外光谱子集，涵盖52个文件夹下的26条记录，总大小546 MB。刺激的时序、顺序及类别标签信息详见IAPS CSV文件。 - **Post_Interv_RestingState**：干预组后测静息态功能近红外光谱子集，涵盖52个文件夹下的26条记录，总大小163 MB。该子集包含30天瑜伽干预完成后的360秒被动静息态采集数据。 - **Pre_Interv_Breath**：干预组前测屏气任务功能近红外光谱子集，涵盖52个文件夹下的26条记录，总大小293 MB。该任务包含5次20秒屏气环节，随后伴随25至30秒的正常呼吸恢复时段。 - **Pre_Interv_Images**：干预组前测情感图片观看任务功能近红外光谱子集，涵盖52个文件夹下的26条记录，总大小563 MB。为减少习惯化效应，实验采用了两种图片呈现序列，参与者分组信息存储于participants.tsv文件中。 - **Pre_Interv_RestingState**：干预组前测静息态功能近红外光谱子集，涵盖52个文件夹下的26条记录，总大小183 MB。该子集包含瑜伽干预前的360秒静息态采集数据，参与者元数据与探头定位文件将单独提供。
