Abstract

The chasse step is one of the most important footwork maneuvers used in table tennis. The purpose of this study was to investigate the lower limb kinematic differences of table tennis athletes of different genders when using the chasse step. The 3D VICON motion analysis system was used to capture related kinematics data. The main finding of this study was that the step times for male athletes (MA) were shorter in the backward phase (BP) and significantly longer in the forward phase (FP) than for female athletes (FA) during the chasse step. Compared with FA, knee external rotation for MA was larger during the BP. MA showed a smaller knee flexion range of motion (ROM) in the BP and larger knee extension ROM in the FP. Moreover, hip flexion and adduction for MA were significantly greater than for FA. In the FP, the internal rotational velocity of the hip joint was significantly greater. MA showed larger hip internal rotation ROM in the FP but smaller hip external rotation ROM in the BP. The differences between genders can help coaches personalize their training programs and improve the performance of both male and female table tennis athletes.

Highlights

With increasing global development and interest, table tennis has become popularized all over the world [1]
This study focused on the key events of the entire motion cycle of the chasse step, so we defined position C as the key event, which meant the end moment of the backward phase (BP)
There was a significant difference in the times between female athletes (FA) and male athletes (MA) throughout the entire motion cycle

Summary

Introduction

With increasing global development and interest, table tennis has become popularized all over the world [1]. The positive technical progress of table tennis performance has placed higher requirements on technical and tactical skills and the mental and physical capacity of the players [2]. Technical and tactical skills are considered to be important performance factors in table tennis. These skills include footwork (one-step chasse, slide, cross-step, and pivot) and strokes (forehand, backhand, smash, service, push, top, top counter top, and others) [3]. Footwork is an essential feature of the technical skill portfolio of table tennis athletes, as footwork is the most important prerequisite in the performance of strokes [1]. Correct footwork allows table tennis players to stroke the ball effectively in the appropriate direction from a strong stance [4]. Footwork training plays a important role in coaching and performance of the sport and has resulted in much scientific interest
