Summary
Archery performance analysis reveals irregular pull-hand displacement negatively correlates with skill. High power in specific frequency ranges indicates tremor, suggesting training improvements.
Area of Science:
- Biomechanics of human movement
- Sports science and performance analysis
Background:
- Understanding the biomechanics of archery is crucial for performance optimization.
- The final push-pull phase is a critical determinant of shot accuracy and consistency.
Purpose of the Study:
- To analyze archery performance using pull-hand displacement measurements.
- To investigate the relationship between displacement patterns and archer skill levels.
- To identify biomechanical factors influencing shot execution.
Main Methods:
- Utilized displacement pull-hand measurements during the final push-pull phase of the archery shot.
- Analyzed displacement signal data across different frequency ranges (0-5 Hz and 8-12 Hz).
- Included eight archers of varying technical abilities.
Main Results:
- Observed irregular pull-hand displacement patterns among archers.
- Found a negative correlation between displacement irregularity and technical skill level.
- Identified significant power levels in the 0-5 Hz and 8-12 Hz frequency bands.
- The 8-12 Hz peak was associated with electromyographic tremor during sustained effort.
Conclusions:
- Pull-hand displacement analysis offers insights into archery technique and performance.
- Irregular movements may indicate suboptimal technical execution.
- Electromyographic tremor is a factor during prolonged archery efforts.
- Biofeedback and strength conditioning may enhance archery training protocols.
