Swing speed refers to the rate at which a golfer or athlete swings their club or bat during a sport. It is typically measured in miles per hour (mph) and can significantly impact the distance and accuracy of the shot. Higher swing speeds generally result in greater ball speed, which can lead to longer drives in golf or more powerful hits in baseball. Factors influencing swing speed include technique, strength, and flexibility. Athletes often work on improving their swing speed through specific training exercises and drills. Understanding swing speed is essential for optimizing performance in sports like golf and baseball.
