VO2= oxygen uptake; HR = mean heart rate; %HRmax= maximum heart rate; RPE-20 = rating of perceived exertion; EE = energy expenditure; VE= pulmonary ventilation; RER = respiratory gas exchange ratio; RF = respiration frequency; EPT = effective playing time; SPR = shots per rally; SF = frequency of the shot; DR = duration of the rally; W:R = work-to-rest ratio; RT = resting time; GN = number of games per match; TS = total serves per match; FS = first serves per match; SS = second serves per match; TSM = total shots per match; Values are expressed as the mean±SD
