Inline Speed Skating Ground Reaction Force Data from University Athletes

A study by Yuya Kimura proposes and verifies methods for estimating ground reaction force direction from supporting-leg posture in inline speed skating. Sixteen experienced university speed skaters performed straight and curved trials, with three-dimensional kinematic and force plate data recorded. The dataset, last updated in April 2026, contains results comparing two estimation methods against force plate measurements.

Use Cases

• Validate biomechanical force estimation models based on supporting-leg posture data.
• Analyze differences in ground reaction force between straight and curved skating motions.
• Compare the accuracy of estimation methods using different anatomical reference points (ankle vs. knee joint).
• Calculate joint torque or power for the supporting leg using estimated force components.

Strengths

• Data is derived from 16 experienced university athletes, providing a controlled subject pool.
• Methods were verified against force plate measurements, with the largest observed error reported as approximately 10% of body weight.
• One estimation method (Est2) consistently exhibited smaller root mean square error values across all skating motions and force components.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small at 331.6 KB, indicating limited scope.
