It is well known by athletes that sleep and athletics appear to go hand in hand. Tired is such an ambiguous word. Although these words are commonly used interchangeably, an important distinction must be made between fatigue and tired.
Fatigue is referred to as overusing the body in and becoming exhausted.
Being tired is from the lack of sleep. An athlete can get the perfect amount of sleep but still become fatigued during a workout. Being tired is directly linked to sleep deprivation. This is important to athletes, especially ones that are involved with extensive travel. People playing on a lack of sleep may not be performing at their optimal level.
