As a sports science expert with a focus on the physics and biomechanics of sports equipment, I have a deep understanding of how changes in equipment design can affect the game. The increase in the size of tennis balls is a topic that has been a subject of considerable discussion and research within the tennis community. There are several reasons why tennis balls have been increased in size, and I will delve into these reasons, providing a comprehensive analysis.
Step 1: English Answer
**Historical Context and Evolution of Tennis Balls**
The evolution of tennis balls has been an ongoing process since the sport's inception. Traditionally, tennis balls were made of a rubber core covered with wool felt. Over the years, the materials and construction have improved to provide better performance and durability. The size of the tennis ball has also changed, with the most recent development being an increase in size.
Regulation and Standardization
Tennis balls are governed by regulations set by the International Tennis Federation (ITF). The standard size for a tennis ball is specified as 2.57 to 2.70 inches (65 to 69 mm) in diameter for professional play. However, in recent years, there has been a move towards larger balls, particularly in recreational and junior tennis. This change is aimed at making the game more accessible and reducing the physical demands on players.
Accessibility and Recreational Play
One of the primary reasons for increasing the size of tennis balls is to make the sport more accessible to a wider range of players, especially beginners and those who are not as physically fit. Larger balls are easier to hit, which can make the game more enjoyable for those who are new to tennis or who may have mobility issues. This can help to grow the sport by attracting and retaining more players.
Reducing the Risk of Injury
Another significant factor in the decision to increase the size of tennis balls is the potential for reducing the risk of injury. Hitting a smaller, harder ball requires more force and can lead to muscle strain or conditions such as tennis elbow. By increasing the size of the ball, the impact force is distributed over a larger area, which can help to reduce the risk of such injuries. The larger surface area of the ball causes it to compress more on the bounce, absorbing more forward energy and resulting in a steeper bounce angle. This can also lead to a slower ball speed, which gives players more time to react and reduces the stress on their bodies.
Performance and Control
Larger tennis balls can also offer improved control for players. The increased size provides a larger sweet spot, making it easier to make solid contact with the ball. This can be particularly beneficial for younger players who are still developing their skills. Additionally, the altered bounce characteristics can provide a different kind of challenge for players, as they must adjust their technique to account for the different ball behavior.
Environmental Considerations
There is also an environmental aspect to consider. Larger tennis balls may have a longer lifespan, as they are less likely to lose pressure and performance over time. This can result in less waste and a more sustainable approach to the sport.
Conclusion
The increase in the size of tennis balls is a multifaceted decision that takes into account the need for accessibility, safety, performance, and environmental sustainability. While there may be some debate about the optimal size for different levels of play, the trend towards larger balls is a reflection of the sport's ongoing evolution and its commitment to being inclusive and player-friendly.

Haake explained the ball's size also makes it bounce from the court at a steeper angle. That's because the larger surface area of the ball causes it to compress more on the bounce and more forward energy is absorbed. ... Hitting the ball hard over a long time can lead to muscle strain or a condition known as tennis elbow.
