Kinematical Analysis on Karen Khachanov’s Tennis Serve Technology

Abstract

Kinematical analysis was made on the 2016 ATP250 Chengdu Tennis Open men's single’s champion, Karen Khachanov’s serve technology. Using the three-dimensional video analysis method to analyze Karen Khachanov’s serve technology, then relevant kinematic parameters was got, thus can provide some data reference for coaches and athletes to improve serve technology. During the throw the ball to take the stage, Karen tossed high quality ball, with large range of truncus twist and relatively fully lateral stretch of the upper truncus muscle; during the back swing stage, Karen’s holding arm was fully flexed the shoulder and elbow, and the fully flexed shoulder can help to serve with force; during the swing the batting stage forward, Karen’s holding arm and truncus were fully stretched, and the force order was in line with whipping action technology principle, from the proximal joint to the distal joint, thus the speed was increasing in order. Analysis and comparison find out that Karen Khachanov’s serve technology was normative and reasonable and it is worthy of imitating for tennis players.
