I can understand how some people do this to concentrate, but from a scientific standpoint, can this also hurt performance? The reason I ask is because performance is affected by music, which is why weightlifters listen to rock music. It helps the person get pumped up and perform better. Likewise, classical music can relax a person, causing the person to not do as much as quickly or effectively. Also, people naturally fall into rhythm with music. Looking at these points, is it possible that listening to music can throw off a bowlers timing, causing mistakes? I see bowlers messing up all the time when the music cuts off suddenly for the strike pots to be drawn while they are mid approach.
