Final answer:
The Eastern grip is historically a popular and versatile grip in tennis, while the Continental grip is preferred for certain shots like serves. The Western grip excels in topspin generation, and the double-handed grip provides power for backhands. Optimal striking on the racquet's 'sweet spot' reduces arm stress.
Step-by-step explanation:
The most popular grip in tennis has evolved over time and can vary based on playing style and surface. However, historically, the Eastern grip has been widely taught for its versatility in producing both flat shots and topspin. It is a neutral grip that allows for a natural swing path on both the forehand and backhand. The Continental grip is often used for serves, volleys, and overheads for the wrist stability it provides. The Western grip, with its extreme topspin potential, is favored on clay courts. Lastly, the double-handed grip, usually implemented for the backhand, provides additional power and control.
When it comes to impacts on the racquet, hitting the ball at various points creates different forces on the hand and can affect the efficiency and comfort of a player. Hitting the ball with the end of the racquet tends to pull the handle away, whereas hitting closer to the shaft pushes it into the palm. For optimal performance and the least stress on the arm, players aim for the racquet's 'sweet spot', which reduces vibration and the risk of tennis elbow.
