Abstract
Physiological, technical, and tactical skills are all important to performance in racquet sports (Lee, 2003). A major determinant of the outcome of a tennis match is the player's physical fitness, which enables them to repeatedly generate power, explosive strokes and rapid court movements during extended matches (König et. al., 2001). Laboratory testing is commonly used to evaluate physical fitness or characterise training effects. It might also be performed for prescribing the sub-maximal training intensities used during the aerobic training for tennis. However, during treadmill testing,the modes of exercise tests (continuous activity) often do not simulate the specific demands of tennis (intermittent activity) and therefore do not reflect the specific muscular involvement of both lower and upper limbs with respect to the stop, start and change of direction movement patterns required during tennis play (Fernandez, 2005).
