Introduction. Tennis is a high-intensity and demanding sport, requiring players to repeatedly engage in a sequence of intense activities, such as accelerations, decelerations, COD, and strokes during a variable period of competition time (on average 90 min; Fernandez-Fernandez et al., 2017).Players commonly complete more than 1,000 CODs in each competitive match (Kovacs, 2009).
