A new dry-land rowing system quantifies athlete kinetics and kinematics during training. This technology provides real-time biomechanical feedback to optimize rowing technique and performance.

Area of Science:

  • Sports Science
  • Biomechanics
  • Ergonomics

Background:

  • Rowing performance relies heavily on precise technique.
  • Objective biomechanical data is crucial for effective training feedback.
  • Existing systems may lack comprehensive kinetic and kinematic analysis.

Purpose of the Study:

  • To develop and validate a dry-land rowing system for quantitative biomechanical analysis.
  • To provide coaches and athletes with real-time data on rowing kinetics and kinematics.
  • To enable detailed evaluation of technique and its impact on power output.

Main Methods:

  • Instrumented Concept II rowing ergometer with force transducer and potentiometer.
  • Four electrogoniometers measuring joint angles (ankle, knee, hip, elbow).

  • Data acquisition computer utilizing a link segment model for kinematic calculations.
  • Main Results:

    • The system successfully quantifies pulling force and handle position.
    • Electrogoniometers provide accurate joint angle data.
    • Computer processes signals, calculates kinematics, and generates visual feedback (animated stick figure with data).

    Conclusions:

    • The developed system offers valuable quantitative insights into rowing mechanics.
    • It facilitates the evaluation of technique modifications on athlete power.
    • The system aids in identifying and differentiating technique variations among rowers.
