Development of a low-cost team performance tracking system

Area of Science:

• Sports Science
• Biotechnology
• Human Movement Science

Background:

• Sports technologies are gaining market share due to their impact on team success and revenue.
• Effective athlete performance tracking is crucial for optimizing team outcomes.

Purpose of the Study:

• To develop and test a novel team performance tracking system for athletes.
• To enable real-time monitoring of internal and external load parameters.

Main Methods:

• A system was developed to measure heart rate, R-R interval, core temperature, and acceleration in volleyball players.
• Internal (heart rate reserve percentage, training impulse) and external (player load) parameters were calculated.
• The ESP-NOW protocol facilitated high-speed, long-distance data transmission for real-time feedback.

Main Results:

• Simultaneous, real-time acquisition of physiological and kinematic data over 3 hours.
• High-frequency, low-cost performance monitoring was achieved.
• Demonstrated the system's capability to provide comprehensive athlete data.

Conclusions:

• The developed system is operable and applicable for enhancing team performance.
• The system aids in reducing the risk of athlete injuries.
• Integrated core temperature monitoring offers unique physiological data not found in current commercial systems.
