The aim of this study was to examine the exercise intensity for women's singles match during an official event. One elite female tennis athlete (20 years old, height 167 cm, weight 62 kg) joined an official singles championship and won the 7(superscript th) finally. A maximal exercise test on treadmill was conducted to measure the physiological profile and calculated the linear regression between heart rate (HR) and VO2 uptake before the event. Afterwards, Digital video and HR were recorded continuously during each match to determine the intensity and estimate the VO2 uptake. Results showed that the VO2 uptake for this subject during maximal exercise test was 42.98 mL•kg^(-1)•min^(-1). The equation for HR and VO2 uptake was VO2=0.2979(superscript *) HR-15.246 (R^2=0.91). During this event, subject underwent four sets which included 46 games. The mean HR during each game was 158.0±10.4 beat per minute (bpm) (almost to 73.5±6.4% VO(subscript 2max)). The maximum HR during each game was 166.3±10.9 bpm (almost to 79.8±7.6% VO(subscript 2max)). The minimum HR during each game was 148.4±10.8 bpm (almost to 67.4±7.5% VO(subscript 2max)). It is concluded that the average highest and lowest physiological demands during each game were changed drastically and rapidly. In addition, the maximal HR and mean HR in won games were significantly higher than that in lost games during this official event (p<0.05).
