男子競技網球單打的型態，是一種短時間的間歇性競賽，持續時間大約是每球4~12秒，每球之間有20~23秒左右的準備時間，持續反覆平均總時間為137~166分鐘，比賽休息比約為1比2.4~3.9。單打比賽後的攝氧量約在46.4%~81.1% VO2(下標 max)、心跳率144~165次／分；乳酸濃度在2.3~7.2 mmol/L，屬於中高運動強度。本文希望透過運動生理學針對競技網球加以分析，瞭解網球運動的特性，讓教練能在安排訓練計畫時有所依據與參考數據，將訓練科學實際運用於選手，以提昇國內網球水準。

During men's single tennis of the mean match characteristics were: rally time, 4~12 s; recovery time, 20~23 s; total time, 137~166 min; work-to-recovery rate, 1:2.4~3.9. The percentage of VO2(subscript max), heart rate and plasma concentrations of lactate were 46.4%~81.1%, 144~165 beats/min and 2.3~7.2 mmol/L. Although tennis is characterized by periods of high-intensity exercise, the over response resembles prolonged moderate-intensity exercise.
