Beta-blockers are a class of drugs which decrease blood pressure and pulse and are used to treat high blood pressure, heart disease, and other medical problems. Beta-blockers also decrease the response of the body to fear or threat, known as the “fight or flight response.” This response usually causes anxiety, tremor, and increased pulse and blood pressure.
The fight or flight response can impair activities such as musical performance and competitive shooting which require concentration and precise movement. Even top musical performers may have performance anxiety or “stage fright,” a type of fight or flight response. Several studies have shown that beta-blockers improve musical performance, probably by reducing anxiety, tremor, and elevated pulse. Performance enhancement has been demonstrated with a variety of instruments, including strings, wind and brass, and piano.
Similarly, beta-blockers improve competitive shooting performance, an activity which requires intense concentration, precise muscle control, and suppression of anxiety and tremor. The International Olympic Committee has banned the use of beta-blockers by shooting sports competitors.
Jascha Heifetz (1901-1987), the greatest violinist of the 20th century, did not need beta-blockers to perform.
