Comparison of laboratory and on-court testing of aerobic ﬁtness in tennis players
The modern game of tennis is characterized by 200-600 explosive eﬀorts over a match that may last up to six hours (Richers, 1995), utilizing speciﬁc movement patterns which diﬀer depending on the tactical situation and court surface. It is clear that the player must be conditioned to meet the speciﬁc aerobic, strength and power demands of these matches in order to maintain the required work rate over such an extended period. Davey et al. (2003) has also indicated that in conditions of fatigue, hitting accuracy decreases by as much as 81 per cent, further illustrating the importance of the physical requirements of the game on the potential match outcome.
