Three Reasons for Playing the Tennis Forehand in Square Stance

Area of Science:

• Sports Biomechanics
• Tennis Performance Analysis
• Injury Prevention in Athletics

Background:

• Competitive tennis requires powerful and accurate forehand shots.
• Understanding biomechanical stances is crucial for optimizing performance and preventing injuries.
• Musculoskeletal wear and tear is a concern for athletes using specific techniques.

Purpose of the Study:

• To compare the effectiveness of open versus square stances in tennis forehand shots.
• To analyze performance metrics including ball speed, accuracy, and gesture economy.
• To inform strategies for reducing athlete musculoskeletal strain.

Main Methods:

• Forty-two healthy tennis players performed 80 forehands each in open and square stances.
• Data collected included ball speed, shot accuracy, and heart rate.
• Statistical analysis used Kruskal-Wallis, Dunn post hoc, and Wilcoxon signed-rank tests.

Main Results:

• The square stance yielded significantly higher ball speeds (6 km/h in lateral, 4 km/h in diagonal-inside running).
• No significant differences were found in accuracy or overall metabolic demand between stances.
• Slight differences in metabolic effort were noted, favoring the square stance.

Conclusions:

• The square stance offers a distinct advantage in tennis forehand ball speed.
• While not statistically significant, accuracy and metabolic effort considerations lean towards the square stance.
• The square stance is suggested as the preferable technique for competitive tennis players.
