A wearable biofeedback control system based body area network for freestyle swimming
Summary
This study introduces a wearable system for real-time trunk rotation feedback in freestyle swimming. The biofeedback improved kinematic performance, reducing session time by 4.5% and aiding daily training.
Area of Science:
- Sports Science
- Biomedical Engineering
- Wearable Technology
Background:
- Wearable sensors enable real-time performance evaluation and feedback for athletes.
- Trunk rotation is a key element in efficient freestyle swimming technique.
Purpose of the Study:
- To develop and evaluate a wearable feedback prototype for measuring trunk rotation in freestyle swimming.
- To assess the impact of real-time biofeedback on swimmers' kinematic performance.
Main Methods:
- A wearable system with a nine-degree-of-freedom inertial sensor and vibration motors was developed.
- The system formed a body area network (BAN) for data collection and feedback delivery.
- Four recreational swimmers performed freestyle swimming sets with and without the biofeedback system.
Main Results:
- The real-time biofeedback mechanism led to an average 4.5% reduction in session time.
- Swimmers demonstrated an ability to adapt to and utilize the feedback signals effectively.
- The system showed potential for integration into daily swimming training regimens.
Conclusions:
- Wearable biofeedback systems can significantly enhance kinematic performance in freestyle swimming.
- The developed prototype is suitable for improving technique and aiding fitness maintenance through consistent training.
- Real-time feedback is a viable tool for optimizing swimming performance and training protocols.
