[Effect of 5HTT genetic polymorphism on aggression in athletes]
The serotonin transporter gene (5HTT) SS genotype may influence aggression in young female athletes. Athletes with the SS genotype showed higher indirect hostility but lower irritability and negativism.
Area of Science:
- Behavioral Genetics
- Sports Psychology
- Neuroscience
Context:
- High emotional pressure is inherent in athletic performance.
- Genetic variations, specifically in the serotonin transporter gene (5HTT), are linked to emotional regulation.
- Understanding these genetic links is crucial for athletes facing intense emotional demands.
Purpose:
- To investigate the association between 5HTT gene polymorphism and aggression levels in athletes.
- To analyze how specific 5HTT genotypes correlate with different facets of aggressive behavior.
- To explore the relationship between genetic makeup, aggressiveness, and competitive success in synchronized swimmers.
Summary:
- This study examined 73 young female synchronized swimmers (ages 8-18) for 5HTT gene polymorphism and 64 for aggression using the Buss-Durkee Hostility Inventory.
- Results indicated that athletes with the SS genotype exhibited higher scores for Indirect Hostility.
- Conversely, athletes with the SS genotype showed lower scores for Irritability and Negativism compared to LS and LL genotypes.
Impact:
- Findings suggest a potential role of 5HTT genotype in modulating aggressive responses in elite young athletes.
- This research contributes to understanding the genetic underpinnings of emotional control and behavior in sports.
- Further investigation could inform personalized training or psychological support strategies for athletes based on genetic predispositions.
