Clinical Sports Medicine

Knowledge about individual strain in competitive ballroom dancing is limited, particular for senior couples. We evaluated the exertion during a simulated final round, covering all five tournament ballroom dances. Heartrate, blood-lactate, and rate of perceived exertion (RPE, Borg-scale) were measure...
