EMG Dataset for Muscle Fatigue Analysis in Biceps and Triceps
Description
The dataset consists of electromyographic (EMG) and arm movement signals from amateur athletes. The EMG signals were acquired with an EMG OYMotion electronic device from the company DFRobot, plus the application of additional stages of conditioning, amplification and digital noise filtering during each measurement, in order to analyze the states of muscle Fatigue and non-Fatigue in biceps and triceps. The other arm movement signals were acquired with a reference 3-axis analog coordinate measurement instrument ADXL335 GY61 (accelerometer and gyroscope). The "BBDD_EMG_Accel" folder contains a file titled "Dataset_labels" with the demographic, somatic and motor information of the 30 participants (25 men and 5 women between 17 and 32 years of age). The other files in this same folder are the signals obtained from each of the subjects, coded from 'Suj' number 1 to number 30. The letter 'B1' and 'T1' are the initial letters of the Biceps and Triceps muscles to indicate the measurement signal obtained in each muscle respectively, and the number that accompanies that letter is to indicate that it was taken in 1: right arm or, 2: left arm. The first row of the data file contains in text format, the name of each column, in this way 4 columns are presented with information in integer format without decimal, where the first column corresponds to the EMG signal, followed by 3 related columns with the 3 coordinate axes (X, Y, Z axis) of the accelerometer, also in integer format without decimal, but with sign, and with a sampling frequency of 1 second. The complementary file titled "ManualSegmentation" seen on the outside, in its first column shows in text format the encoded file names of all the acquired signals, and in its first row in text format the abbreviations PI_1, PF_1, ..., PF_4, to indicate the start and end points of the segments of the exercise series in integer format without decimal, which in later publications were used to train a binary classifier of the Fatigue state.
Files
Steps to reproduce
Data, labels, manual segmentation are files provided in .xlsx format. The first column and first row contain information in text format about the signal labels or names. The following columns are numeric data in integer format without decimal, but with a sign. These files can be processed in any software or library package enabled to read Excel workbook files.
