<span>Studies have shown that a number of psychological factors might predispose an athlete to an acute injury. Different people have different “mind-sets” for the competition and intensity of exercise or sports. If you’re overly “psyched out” by the importance you place on the number of repetitions you can do or the number of games you win, or if the environmental conditions in which you must perform aren’t ideal (“it’s too windy/cold/hot”), your psychological state could detract from your performance and put you at risk for injury. If you’re already injured and are still engaging in activity, this, too, can be a distraction that puts you at greater risk.</span>
From what I understand mental alertness helps you decide from what's dumb and what you should be doing like for example.... if someone went to go walk across the street it's your mental alertness that helps you see if it's safe or not... your mental alertness can transfer signals to your body why helps you stop doing it physically so if a car was coming and you were in the middle of the walking your brain censors the danger that is approaching to have you run across or to not cross at all; where as the driver mental alertness sees the danger on what's happening so that's put into physical alertness to stop the car...... but truly i dont know it's worth a shot
