ABSTRACT
Squash imposes diverse physiological demands on cardio-pulmonary endurance, muscle endurance, explosive strength, speed and flexibility (Sharp, 1998). At élite level, squash has been classed as a high-intensity intermittent activity with mean rally lengths of 16-21 s and recovery times of 10-16 s between rallies (Montpetit, 1990; Hughes and Robertson, 1998). Professional matches can last for 3 h during which players are active for up to 67% of the time (Montpetit, 1990). This makes marked challenges to energy supply.
