ABSTRACT
The ergonomics demands of soccer play are determined by the exercise intensities at which the myriad of skilled activities during match-play are performed. These can be represented by work-rate profiles, work-to-rest ratios and patterns of play for both individual players and the team as a whole, and then viewed alongside those of opponents. Analyses of such demands provide insights into both fitness and training requirements. Since the training and competitive profiles of players comprise their occupational roles, their demands have consequences for habitual activities, daily energy expenditures and energy requirements. There are repercussions also for prevention of trauma and avoidance of overuse injuries.
