The use of elite professional players is essential when determining the range of launch values achievable from kicking a soccer ball. They give credibility to the tests and ensure that the resulls obtained are close to the maximum values achievable. The data obtained from this study could be used to set appropriate dynamic standards for soccer balls to ensure ball performance consistency and limiting conditions.
