Body language plays a significant role in sports performance by influencing both the athlete's perception and the opponent's reaction. Positive gestures like open posture and eye contact can enhance an athlete's confidence and focus, leading to improved performance. Conversely, negative body language may convey fatigue or uncertainty, potentially impacting game dynamics. Moreover, observers often interpret body language as a signal of intent or ability, which can psychologically affect competition. Therefore, mastering body language can serve as a critical tool for athletes aiming to gain a competitive edge.
