This document discusses the influence of music on exercise and sports performance. It references several studies and publications by exercise scientists Dr. Costas Karageorghis and Dr. Daniel Bishop on the psychological effects of music. Some of their key studies examined the relationship between music tempo and exercise intensity, and the ergogenic and psychological impacts of synchronous music during treadmill walking. They developed a tool called the Brunel Music Rating Inventory to measure the motivational qualities of music for exercise. The document also briefly discusses the influence of Latin music styles like salsa and cha-cha on popular American music from the 1930s to 1950s.
