Force Plates

Mesure des forces de réaction au sol.

Designation:

Force plates for measuring the ground reaction forces exerted by the body.

 

Manufacturer: Various manufacturers (e.g., AMTI, Kistler, Bertec).

 

Main Function:

  • Measurement of vertical, horizontal, and lateral forces during movements (jumps, running, balance).
  • Biomechanical analysis of athletic performance and technique.
  • Used in scientific research, physical rehabilitation, and strength & conditioning.

 

Technical Characteristics:

Sensors: High-precision integrated strain gauges or piezoelectric sensors.

Measurement Range: Up to 5,000–10,000 N depending on the model.

Sampling Frequency: 1000–4000 Hz.

Dimensions: Vary by model (portable or fixed laboratory setups).

Output: Forces, moments, and Center of Pressure (COP).

Includes dedicated software for data acquisition and advanced biomechanical analysis.

 

Usage:

  • Vertical and horizontal jump testing (CMJ, SJ, etc.).
  • Gait analysis (walking and running).
  • Post-traumatic or post-surgical orthopedic rehabilitation.
  • Biomechanics research and sports performance optimization.

 

Advantages:

✔ Extremely high precision and measurement accuracy.

✔ Comprehensive analysis of 3D forces and moments.

✔ Fully compatible with other biomechanical tracking systems (EMG, 3D motion capture).

 

Limitations:

❌ High acquisition cost.

❌ Limited portability (except for specifically designed compact models).

❌ Requires precise installation and regular calibration.
