ABSTRACT
During a soccer game, elite level players cover 8-13 km (Reilly and Thomas, 2003). The majority of the activity in the game is performed as low-intensity exercise such as walking, jogging or slow running. The sub-maximal nature of this activity predominantly uses aerobic energy sources. However, within this endurance context, numerous explosive bursts of activity are required, including sprinting, jumping, turning and tackling. Sprint-type activities account for about 8–12 % of the total distance covered in the game (Rampinini et al., 2007). The maximal nature of these activities stresses anaerobic energy sources of ATP-CP and glycolysis. Therefore, soccer training should enhance both aerobic and anaerobic abilities.
