Biomechanical Analysis Of Double-Handed Backhand Drive Technique: Square Stance Vs. Open Stance"

Abstract

Study purpose: The main purpose of this study is a comprehensive biomechanical analysis of square stance and open stance in tennis backswing. The analysis involves examining the different variations between two-handed tennis players focusing on open stance and square stance.

Materials and methods. This study is a descriptive research with biomechanics analysis involving 30 Junior male tennis Players who have played AITA tournaments. The age range of  players are 12-14 years. The Hewitt Tennis test was applied for the analysis of Open stance and Square stance.  Analysis of biomechanical variables using descriptive statistics and correlation between different variables was tested using Pearson's Product Moment Correlation. A comparative test was conducted to assess the difference between various variables in the square stance and the open stance. The significance level for this test was set at an alpha level of 0.05, ensuring statistical robustness.

Results. The first goal was to determine the comparison between a square stance and an open stance of the tennis backswing. Analysis of the study revealed that there is a significant difference between the right shoulder joint in square posture and open posture as p-vale (0.022) is less than .05.

Conclusions. The strike zone of the two strikes is different in the square stance and the open stance. In the square stance, the contact point is slightly earlier than in the open stance. An open stance can be used in defensive situations. The square stance recruits more large muscle groups to initiate the kinetic chain, which makes it more effective, but it also means we have to take an extra step on the ball, so we have to work a little harder to get there first.
