Snatch Lift Biomechanics from Inertial Motion Capture and EMG Data

Shu Zhang's dataset on figshare contains biomechanical data from 23 youth weightlifters aged 15–18 performing snatch lifts at 70%, 80%, and 90% of their 1RM. Data includes inertial motion capture and EMG recordings, with deep muscle forces and joint loads calculated using OpenSim. The dataset was last updated on April 14, 2026.

Use Cases

• Modeling muscle activation patterns based on EMG data mentioned in the description
• Analyzing joint reaction force changes based on load percentage (70-90% 1RM)
• Training technical evaluation based on inertial motion capture data
• Developing personalized injury prevention strategies based on calculated deep muscle forces

Strengths

• Data from 23 participants provides a sample for analysis
• Includes data at three distinct load levels (70%, 80%, 90% of 1RM)
• Integrates multiple data sources: inertial motion capture and EMG
• Muscle and joint forces were calculated using the established OpenSim software

Limitations

• Row count and column-level documentation are absent; field semantics must be inferred after download
• Data is from a specific demographic (youth weightlifters aged 15-18), which may limit generalizability
• Dataset size is 42.9 MB, which may limit the scale of analysis
