Which of the following factors can positively affect an athlete's performance?

Positive self-talk significantly influences an athlete's performance by enhancing mental resilience, focus, and motivation. When athletes engage in constructive internal dialogue, they can build confidence, reduce anxiety, and maintain a more optimistic outlook, especially during challenging situations. This mental strategy allows them to push through adversity, maintain concentration on their goals, and improve their overall performance.

In contrast, anxiety levels can hinder performance by creating distractions and increasing stress. Lack of preparation typically leads to poorer outcomes due to insufficient training and knowledge of the sport or event. Physical exhaustion directly impedes an athlete's ability to perform optimally, reducing strength, agility, and cognitive functions necessary for competition.
