This refers to total distance covered by a player during a game (male hockey players cover 7-11km during a 70-minute game). This compares to 10-13km in soccer, 12-18km in Australian Rules and 6-10km in Rugby. A secondary variable related to total distance covered is the decrement between the first and second halves (it is common for players to cover 5-10% less distance in the second half). A large decrement in distance covered usually results from a lack of fitness or a slowing of the game due to a one-sided score-line.
