A wireless sensor system for a biofeedback training of hammer throwers.

Area of Science:

• Sports Science
• Biomechanics
• Athletic Training

Background:

• Men's hammer throw performance has stagnated since 1986, potentially due to a lack of advanced training methods.
• Effective training requires quantifiable biomechanical data for performance analysis and improvement.

Purpose of the Study:

• To develop a real-time biomechanical feedback system for hammer throw training.
• To establish scientifically described training targets and performance metrics.
• To quantify key characteristics of an effective hammer throw.

Main Methods:

• Development of a wireless sensor system incorporating an infrared proximity sensor and a load cell.
• Utilizing XBee for data transmission and an Arduino processor for data processing and system control.
• Measurement of hip vertical movement and hammer wire tension during throws.

Main Results:

• The developed system effectively measures critical biomechanical data in real-time.
• Wire tension measurements provide sufficient key features for detailed performance analysis.
• The system enables coaches to deliver immediate feedback to athletes.

Conclusions:

• The wireless sensor system offers a viable solution for enhancing hammer throw training.
• Real-time biomechanical feedback can significantly improve training efficiency and athlete performance.
• This technology addresses the need for objective data in athletic development for hammer throw.
