The study aimed to explore the effect of elite tennis player body kinematics during preparatory, force generation and follow through phase ( between  first serve and second serve) at three different time periods i.e. initial, mid and end of the match. Four Indian International male tennis players were selected as subjects for the study. The mean and standard deviation of players of age (year), height (cm) and weight (kg) were 27.00 ± 4.97, 186.50 ± 6.03, 81.25 ±7.41, respectively. The tennis service was modeled as segments of the kinematics chain composed of body segments. 2D kinematics data of the body were obtained for this study with the high speed canon camcorder operating at the shutter speed of 1/2000 with a frame rate of 50 Hz. Descriptive statistics and t-test were performed by SPSS version 17.0 for all the variables under this study were computed at Level of significance for 0.05 with 6 degree of freedom. Results revealed that selected kinematics variables of selected subjects does not play significant role in first and second serve at different phases during three different stages of the Tennis match
