The Effect of Caffeine on Typing Speed, Accuracy and Heart Beat
The effect of caffeine on typing speed, accuracy and heart beat
1. Introduction
Caffeine is a substance found in coffee, tea and most sodas. When it is consumed, it is a mild stimulant. The energy drink, Monster, contains caffeine, which has the ability to manipulate adenosine (adrenaline), a substance present in the brain that is used to transmit brain signals to different parts of the body. Adenosine causes an increase in alertness and awareness. Modern studies show that there is direct benefits of the so-called “caffeine kick” that is experienced by drinkers.
The behaviour of caffeine acts as a stimulant which increase brain memory. Caffeine belongs to the xanthine chemical group that has an influence on the central nervous system. Adenosine is viewed as a xanthine and is found throughout the brain where it acts as a transmitter of brain signals.
2. Problem Statement
Energy drinks such as Monster, Red Bull and Play are popular energy drinks used by high school learners and university students to help them to stay awake.
People report that caffeine gives them a "lift”, makes them feel less drowsy, less fatigued and more capable of rapid and sustained intellectual effort. They also report improved performance of some manual tasks such as driving. Studies also indicate that caffeine can diminish performance of manual tasks that involve delicate muscular coordination and accurate timing.
Numerous studies have been conducted to examine how caffeine affects your reflexes and reaction time. Several studies have confirmed that your reaction time generally improve with moderate amounts of caffeine.
Researchers also found that students given the lowest dose of caffeine used in a study — equivalent to half a can of Red Bull – had the best responses to a reaction-time test, which required them to respond to targets on a computer screen. It was also found that those who drank more caffeine had slower reaction times. Participants were also asked how
