Many people believe that playing golf is like strolling in a courtyard; it is not a sport that requires good physical training, and one can just jump in and play any time, which results in lack of knowledge of injuries caused by playing this sport.  In fact, injuries in areas such as the back, elbow (commonly known as golfer’s elbow), shoulder, and knee, can quietly sneak up on people with this casual attitude.  Especially those golf enthusiasts, who practice over time and love to compete with each other to see who can drive the farthest, resulting in hitting the ball too hard, are injured easily.  One should know that golf is not a natural sport.  For example, the human waist does not like to bend and twist all the time, and the shoulders are not suitable for moving upwards and downwards with force.  Moreover, the swing motion of golf is unnatural; it is a rather awkward, unilateral and asymmetrical sport.  Therefore, one should not spend too long or use too much force playing golf.  Superstar Tiger Woods suffered knee and back injuries for a long time, and they almost ruined his career.
