When measuring the reaction time, first, ask the subject to place his or her finger and thumb approximately 2 cm apart. Next, hold a 30 cm ruler vertically between the thumb and forefinger of the subject. The lower end sho uld be even with the top of the thumb and forefinger. After that, drop the ruler.

After running, they measure the reaction time again. Person who was drinking water, has higher reaction time (left hand : 18,3 ; right hand : 28,3). Person who was drinking Gatorade, has lower reaction time (left hand : 9,0 ; right hand : 16,3 ). After running, the body lose much electrolytes. It decreases nerve and muscle contraction. It cause you catch the ruler slower during measuring reaction time. Sport drink contains electrolytes such as calcium and potassium. Electrolytes are essential for nerve and muscle action.
