Personality traits significantly affect athlete competitiveness, influencing how they respond to challenges and setbacks. Traits such as self-discipline, motivation, and a strong desire to improve contribute to an athlete's drive for success. Athletes with high levels of confidence and resilience often perform better under pressure, maintaining focus even in high-stakes situations. On the other hand, traits like anxiety or low self-esteem can hinder performance. Understanding these traits enables coaches to tailor development strategies, enhancing mental toughness and overall competitiveness in athletes.
