and the opposite is probably true for less trained subjects.
The soccer players in this experiment showed a higher VO2MAX than that reported previously,4 but in line with results reported by Wisløff et al.9 However, the players in our study do not represent a whole team, and, as volunteers for an endurance experiment, they probably have a genetic predisposition for endurance performance. Therefore, the VO2MAX results cannot be generalised to all groups of soccer players. Monitoring heart rate during play would give the coach valuable information about training effects.
