False. According to Pitts and Stotlar (2013) and Pitts (2016), while competition is a defining characteristic of many sports, it is not a necessary requirement for an activity to be considered a sport. They define sport as "an institutionalized activity that involves physical exertion and skill in which individuals or teams compete against one another for entertainment." This definition emphasizes the importance of physical exertion, skill, and competition in sports, but does not require competition in all cases.
