Even among amateurs, it is now a habit to follow a proper diet, in order to take all the necessary elements, in order to help the player give the best of oneself on the court.

Dietary fat intake should not exceed 2 g·kg(-1)·d(-1).Caffeine in doses of 3 mg·kg(-1) can provide ergogenic benefit when taken before and/or during tennis match play.200 mL of fluid containing electrolytes should be consumed every change-over in mild to moderate temperatures of < 27°C but in temperatures greater than 27°C players should aim for ≥ 400 mL.30-60 g·hr(-1) of carbohydrate should be ingested when match play exceeds 2 hours."
