Usually a decrease in performance can be traced to improper nutrition. Therefore, what you eat determines how you supply energy to the body before workouts and practices. After your workout or practice, you want to replenish all the nutrients that you have utilized to speed up recovery. The body cannot recover between workouts without enough rest. Getting enough rest should be high on your priority list, especially during periods of physical and mental stress.
Athletes play with controlled speed, where acceleration, agility and power are the main factors.
The primary concern of every coach and athlete is to develop the maximum amount of speed possible. Often times, coaches take the wrong approach to speed development.

Regardless of what sport you play, being able to change directions and accelerate is a primary aspect.
