Aerial and Terrestrial Patterns: A Novel Approach to Analyzing Human Running

Area of Science:

• Biomechanics
• Sports Science
• Gait Analysis

Background:

• Running gait is a complex dynamic system where parameters are interconnected.
• The Volodalen® method offers a subjective classification of running patterns (aerial vs. terrestrial).
• Validating subjective assessments with objective biomechanical data is crucial for understanding running mechanics.

Purpose of the Study:

• To validate the Volodalen® method by correlating subjective running pattern classifications with objective biomechanical measurements.
• To determine if distinct biomechanical parameters differentiate aerial and terrestrial running styles.

Main Methods:

• 91 individuals were subjectively assessed using the Volodalen® method by an expert coach.
• Objective biomechanical parameters were measured using OptojumpNext® during 50-m runs at various speeds (3.3, 4.2, 5 m/s).
• Comparison of biomechanical data between subjectively classified aerial and terrestrial runners.

Main Results:

• Terrestrial runners showed longer contact times and greater leg compression compared to aerial runners.
• Aerial runners exhibited longer flight times, greater center of mass displacement, and higher leg stiffness.
• Subjective running pattern classification was significantly associated with objective biomechanical parameters.

Conclusions:

• The subjective Volodalen® method effectively categorizes running patterns that correspond to distinct objective biomechanical characteristics.
• Holistic, subjective assessment of running provides valuable insights into individual running gait biomechanics.
• This validates the use of the Volodalen® method in sports science and coaching for gait analysis.
