4. Digestive System
Before practicing for softball or playing a softball game you should eat things that have lots of carbohydrates. Carbohydrates give you lots of energy that slowly digest, so you have lots of energy for a long time. A food that has lots of carbohydrates is pasta, vegetables, fruit, beans, whole grains, nuts and yogurt.

5. Immune system
Even the slightest cold can throw off your game, it make you tired and weakened, so you need to be fully healthy to be at your best. Also if you do have a cold or something else you should take a break from playing softball so that you have time to recover.

The circulatory system has to work with the respiratory system to play softball. While your lungs are inflating and deflating fast your heart is pumping faster and faster as you run more in the game.
