His first book, Learning Capoeira: Lessons in Cunning from an Afro-Brazilian Art (Oxford, 2005), was a study of the Afro-Brazilian dance and martial art, and he has published extensively on capoeira, no-holds-barred fighting, coaching, dance, music and other skills. Downey is especially interested in the ways physical education and training regimes in different cultures generate distinctive physiological capacities, behavior patterns, sensory abilities, and skill sets. His current research is on rugby training in Australia, New Zealand, and among Pacific Islanders.
