Summary
Autonomic nervous system (ANS) activity in sharp shooters reveals distinct physiological responses during successful shots. Higher motivation and concentration correlate with specific electrodermal responses, indicating better performance mastery.
Area of Science:
- Sports Science
- Physiology
- Psychology
Background:
- Understanding the physiological underpinnings of elite performance is crucial in sports.
- The autonomic nervous system (ANS) plays a significant role in regulating bodily functions during demanding tasks.
Purpose of the Study:
- To investigate the relationship between autonomic nervous system (ANS) activity and performance in rifle sharp shooters during competition.
- To identify physiological markers associated with successful shots versus misses.
Main Methods:
- Simultaneous recording of electrodermal, thermovascular, and cardiorespiratory variables in 15 sharp shooters (10 male, 5 female).
- Measurement of two performance indices during live competition.
- Analysis of ANS responses in relation to shot accuracy (hit vs. miss).
Main Results:
- Successful shots were associated with a higher number of negative skin potential responses compared to missed shots.
- These responses during successful shots exhibited lower amplitude but longer duration.
- Physiological patterns suggest a link between specific ANS activity and performance outcomes.
Conclusions:
- Good performance in sharp shooting is linked to high motivation, indicated by increased negative potential responses.
- Effective emotional reactivity control, shown by low-amplitude responses, is vital.
- Enhanced concentration, reflected in longer response durations, contributes to successful performance.
