... mechanisms during a game, was that the measurement of certain variables such as oxygen uptake (VO2) would interfere with match play and only small parts of a match could be analyzed (Bangsbo, 1994). As a result, several laboratory-based exercise protocols were developed to measure metabolic and physiological responses in intermittent exercise (Holmyard et al., 1988; Nevill et al., 1995). However, they are generally too uniform to represent the complex nature of a soccer game. Drust et al. (2000) went on to develop a protocol that includes variations in the intensity and duration of exercise as well as a more irregular resting period to simulate the intermittent trait of a soccer game. This soccer-specific treadmill protocol is more representative of match-play work rates; it allows one to examine physiological responses and quantify physiological performance in a soccer game. The aim of the present paper is to critically evaluate this laboratory based ...
