Exercise Psychology has grown substantially in recent years and has now matured into an established and widely studied discipline. Many universities offer graduate and undergraduate programmes in exercise science worldwide, and there are a number of scientific and applied journals in the field that have published a huge body of scholarship. This new four-volume collection from Routledge, edited by two leading scholars in the field, brings together the key material published across these various sources to create a ‘mini library’ of the foundational writing and the very best contemporary research.
