Most of the fatigue index is a term used to describe a method for determining the depletion of energy during aerobic exercise. Shows the power output reduction rate in the index numbers of players. This is to determine the index of aerobic athletes are tested for the sprint endurance.A player fatigue can be used as an indicator of the general method. Competitors will warm up for about 10 minutes to give a five to three-minute break. She then, and 10 seconds break between each sprint, run the six-meter sprint 35-30. Each time has been recorded in the Sprint stopwatch. To determine the fatigue index of players, first to determine the power output in watts of each sprint is. This rate is determined by multiplying the power of Sprint Sprint. Velocity is determined by the power of Sprint's time sprint.To, in meters, is determined by dividing the distance divided by time sprint speed, acceleration, must be determined. Weight is multiplied by the acceleration km sprint athletes. This number is equal to the power of Sprint. Fatigue index was divided by the total time of all six sprints are found by subtracting the maximum power from sprint sprint minimal power.
