The performance you get out of your body is directly impacted by the fuel you put into it. Your body converts food to energy and requires proper nutrition to build the muscle that will increase strength and speed for an athlete. Consuming enough complex carbohydrates will have a direct impact on the energy stores you have during sports performance. Good complex carbohydrates sources are spaghetti, rice baked potato and whole-meal bread.
Protein intake will impact your ability to develop muscles and gain speed and strength improvements over-time. After strength training, an immediate protein intake will help your body.
Excess fat has a negative impact on sports performance and should be avoided.
You should drink eight to 10 glasses of water each day and hydrate with water or sports drink before, during and after competition.
