Data Records

Subjective measurement data including participants' self-reported muscle fatigue rank, physiotherapist's palpation-based assessment of muscle stiffness during the 4-minute experiment with 30-second intervals, and final assessment of muscle fatigue were summarised in Excel spreadsheet format (e.g., <em>SelfReported_Subject01.xlsx and PhysioPalpation_Subject01.xlsx</em>). <em>readme.pdf </em>with instructions about loading the dataset, running the code, and code execution. <em>Subject: </em>Each data file is named according to the participant number, which is an integer ranging from 1 to 30. <em>Muscle stiffness measurements for 4 minutes with 30-second intervals:</em> The subjective data records for each participant include the physiotherapist's palpation-based measurements taken at 0s and 30-second intervals for a total of 8 times across nine muscle locations. <em>Physiotherapist's palpation-based muscle tightness Rank 1, Rank 2, Rank 3: </em>Followed by the muscle stiffness measurement with 30-second intervals, the data records for physiotherapist-assessed muscle tightness rank 1, 2, and 3 contain the evaluations conducted by the physiotherapist to assess muscle tightness. Each record includes the participant number, the rank of muscle fatigue assigned by the physiotherapist (1, 2, or 3), and the associated muscle location. These records reflect the expert judgment of the physiotherapist regarding the severity and localization of muscle fatigue, providing valuable objective assessments of muscle condition during the experimental sessions. <em>Self-reported muscle fatigue Rank 1, Rank 2, Rank 3:</em> The data records for self-reported muscle fatigue rank 1, 2, and 3 include information on the participants' subjective assessment of their muscle fatigue levels. Each record specifies the participant number, the rank of muscle fatigue (1, 2, or 3), and the corresponding muscle site. These records provide insights into the participants' individual perceptions of muscle fatigue and contribute to understanding the subjective experience of fatigue during the experimental sessions. <br> Raw data contains sEMG data for all subjects with nine muscles. The sEMG time and signal data were collected via a Bluetooth module and an in-house data acquisition (DAQ) system. The recorded data was stored in Excel Spreadsheets in .xlsx format, with each participant's data saved in a separate file (e.g. <em>Subject01.xlsx</em>). Time: The sEMG raw time data consists of the time series measurements recorded from the sEMG sensors. These sensors captured the electrical activity generated by the muscles during the experimental sessions. Each data entry in the time series corresponds to a specific time point. The sEMG raw time data is stored in an <em>Excel spreadsheet (.xlsx)</em> using <em>Time [s]</em> format. Raw sEMG signal: The sEMG raw signal data contains the amplitude of the electrical signals recorded by the sEMG sensors. These signals represent the muscular electrical activity and provide insights into the muscle's activation levels during the experimental sessions. Each entry in the signal data corresponds to a specific time point, reflecting the magnitude of the electrical activity at that particular moment. The sEMG raw signal data is stored in an <em>Excel spreadsheet (.xlsx)</em> using <em>Avanti sensor 5: EMG.A 5 [V]</em> format. <br> For any further information, please contact Jihoon Lim ([e-mail]).
