title="Effects of low-volume court-based sprint interval training
on aerobic capacity and sport-specific endurance performance
in competitive tennis players",
abstract="Sprint interval training (SIT) is a potent exercise strategy to enhance athletes’ aerobic capacity in a time-efficient manner. The purpose of this study was to examine the effect of a low volume court-based SIT program on aerobiccapacity and sport-specific endurance  performance forcompetitive tennis players. Sixteen competitive collegiate tennis players were randomly assigned to the SIT (court-based repeated-sprint training) and traditional endurance training (ET; 45-min continuous treadmill running) groups for a 6-week intervention (3 sessions/week). The maximal oxygen uptake (V̇ O 2max ), minute ventilation at peak exercise (VEmax), ventilatory anaerobicthreshold in percentage of V̇ O 2max  (VT/VO 2 ), and elimination rate of blood lactate (BLA er ) were assessed, whereas the Yo-Yo Intermittent Recovery Test Level 2 (YoYo-IR2) and the tennis-specific HIT\&TURN test were conducted at baseline and after the intervention. Both SIT and ET showed significant improvements in V̇ O 2max  ( p  < 0.01) with moderate effect sizes (ES = 0.64 and 0.98, respectively), as well as in VE max  ( p  < 0.01) with small effect sizes (ES = 0.23 and 0.21, respectively), and VT/VO 2  ( p  < 0.01) with large effect sizes (ES = 2.37 and 3.85, respectively). The BLA er  improved significantly in SIT (ES = 1.03;  p  < 0.05) whereas no significant changes occurred in ET. The magnitude-based decision showed a  clear and superior improvement in both YoYo-IR2 (ES = 0.69) and HIT\&TURN (ES = 1.72) tests in SIT than ET. Compared with traditional ET, court based SIT can be a time-efficient strategy to improve aerobic capacity and tennis-specific endurance without requiring specialized equipment for competitive tennis players.",
