Which technique is NOT considered a psychological strategy for performance enhancement?

Strength training is not classified as a psychological strategy for performance enhancement because it primarily focuses on the physical development of muscles and overall bodily strength. This type of training enhances physical performance through physiological adaptations, such as increased muscle mass, improved endurance, and greater power output.

In contrast, self-talk, goal setting, and visualization are all psychological techniques aimed at improving mental preparedness, focus, and motivation. Self-talk involves the internal dialogue that athletes use to encourage themselves or manage anxiety during performance. Goal setting helps athletes define clear, measurable objectives, which can enhance motivation and provide direction for their training. Visualization is a technique where athletes imagine themselves performing successfully, which can improve confidence and decrease anxiety. These strategies work on the mental aspects of performance, highlighting the distinction between psychological and physical training methods.
