Reaction time
Fear can improve (shorten) reaction time.
The Dark Reaction DOES occur at night... I'm just not sure WHY....
In general, cooling a solution slows the reaction. You can use the Arrhenius equation to figure out what effect a given temperature will have on a particular reaction (you'll need to know the activation energy).
If you're a receiver it is important because if your reaction time is off by just a bit, you could end up like Joshua Cribbs. If you are a quarterback it is important so you don't fumble the snap when you hike the ball.
swimmers need a good reaction time because they need to time then to come of the block and enter the water
You need good reaction time to play soccer as it can be a very fast game and you often have to make quick decisions.
they need good reaction time because when they see the shuttlecock coming they need to act instantly to return the shuttlecock

To be a footballer, you need to train hard, eat a right diet,and balance out your food, you need to have either or both stamina and speed, strengths...
a footballer will need aerobic endurance because: a match lasts 90minutes and they will need to be active for much of his time. they need to be able to perform at a high level for the whole match. many injuries occur when a footballer gets tired- therefore they need good levels for aerobic endurance to reduce the possibility of an injury.
