Influence of tennis specific endurance training on maximal oxygen uptake andrepeated sprint ability with change of direction in male tennis players

The purpose of the present study is to assess the influence of tennis specific endurance training for eight weeks on maximal oxygen uptake and repeated sprint abilitywith change of direction – total time, mean time & fatigue index in male tennis players. Twenty (20) male tennis players were selected at random as subjects, who volunteered to participate in this study. All players were classified randomly into two groups tennis specific endurance training group (EG) (n = 10) and control group (CG) (n = 10). These players were selected from National Tennis Academy, SIPCOT, Ranipet, Tamilnadu during the academic year 2018 – 2019.Maximal oxygen uptake and repeated sprint ability with change of direction (RSACD) – total time, mean time and fatigue index was selected as criterion variables. The eight weeks of tennis specific endurance training was supplemented to EG and CG carried out their regular training. The result of the study revealedthat EG from pre to post test showed significant improvement in maximal oxygen uptake(F (1, 18) = 36.86, p = 0.000) and RSACD – total time (F (1, 18) = 11.71, p = 0.003), mean time (F (1, 18) = 11.71, p = 0.003) & fatigue index (F (1, 18) = 7.133, p = 0.016) but the CG failed to show significant changes (p> 0.05). It is concluded that eight weeks of tennis specific endurance training is likely to improvemaximal oxygen uptake and RSACD – total time, mean time, & fatigue index in tennis players. This study also displayed the effectiveness of 30-15 IFT audio which can also be used for trainingand it is evident inimproving the maximal oxygen uptake and RSACD – total time, mean time, & fatigue index in tennis players.
