Participants

120 participants, all male, organised as two age cohorts (subject ID is confounded with age):

Cohort	Subjects	N	Mean age	Age range
Young (YG)	S001–S060	60	~23 yr	20–25
Older (OG)	S061–S120	60	~47 yr	40–59

Aggregate (n=120): age 35.4 ± 12.9 yr · height 1.73 ± 0.06 m · body mass 74.2 ± 12.5 kg. Per-subject values are in subject_metadata.csv (adds an age_group column) and in the original Subject_Demographics.xlsx / Anthropometric_Data_Participants.xlsx.

Directory structure

Subjects are grouped in blocks of ten:

Gait120_001_to_010/
  S001/
    EMG/ConvertedData.mat                         # interpolated EMG per trial/step (LevelWalking)
    JointAngle/LevelWalking/TrialXX/stepYY.mot    # OpenSim inverse-kinematics joint angles (deg)
    MotionCapture/LevelWalking/
      TRC/TrialXX/{Step01.trc, Step02.trc, AllSteps.c3d,
                   mosh_results/.../AllSteps_stageii.pkl}   # markers, C3D, SMPL (MoSh++) fit
      MOT/TrialXX/{Step01.mot, Step02.mot}         # ground reaction forces (2 force plates)

Coverage notes

• EMG ConvertedData.mat: all 120 subjects.
• JointAngle/LevelWalking (.mot): all 120 subjects.
• MotionCapture TRC + SMPL fit (AllSteps_stageii.pkl): all 120 subjects (5 trials each).
• Ground reaction forces (MotionCapture/.../MOT/): S011–S120 only (110 subjects). S001–S010 have no processed GRF in the source dataset.

Relationship to the original dataset

Added files:

• For each subject and trial, MotionCapture/LevelWalking/TRC contain mosh_results (SMPL-retargeted motions) in AllSteps_stageii.pkl;
• For each subject, original .mat files contained opaque objects so they were converted (ConvertedData.mat).

To keep the archive compact, the following were removed relative to the figshare release:

• EMG/RawData.mat and EMG/ProcessedData.mat (only ConvertedData.mat retained);
• all non-LevelWalking movements (StairAscent/Descent, SlopeAscent/Descent, SitToStand, StandToSit) under JointAngle/.
