Increased muscle enzyme activity after yoga breathing during an exacerbation of asthma

Abstract

The case is reported of a yoga practitioner who, during an exacerbation of asthma, developed a substantial increase in serum muscle enzymes. This was related to his yoga breathing exercises, which he used to enhance the delivery of aerosolised bronchodilators. As his condition improved and the use of these yoga manoeuvres diminished, the muscle enzyme levels fell to normal.
