Negative self-talk can significantly impact exercise performance by diminishing motivation and self-confidence. When athletes engage in critical or defeatist thinking, it can lead to increased anxiety, distraction, and lack of focus during workouts. This detrimental mindset may result in a decline in performance-related outcomes, such as speed, endurance, or technique. Actively practicing positive self-talk and visualization techniques can counteract these negative thoughts, fostering a more constructive mental framework that supports athletic achievement and overall enjoyment of physical activities.
