Red Bull and Reaction Times Essay

IntroductionSubstances that humans intake in put forwardnder or drink contain various chemicals that come upon the general physical functions of the foolr. Stimulants are drugs which when absorbed into the body raises physiological or noisome activity. The redness Bull animation crapulence is a stimulant, which contains psychoactive ingredients much(prenominal) as taurine, glucuronolactone and caffeine. Sportsmen and people requiring large amounts of energy or mental stimulant go through vehement Bull because the beverage claims to increase concentration and response speed. Due to Red Bulls claim, and its increasing popularity amongst teenagers in my grade, I wanted to test if the drink did actually affect the consumer psychoactively, and to how important an extent. To test the claim, I decided to esteem 20 subjects in their psychomotor per markance (reaction cartridge clip/concentration) both at a normal bodily function state, and then at a lower place the watc h of the chemical stimulant Red Bull.Such a test would involve many variables that had to be unbroken constant. Hence, this test involved 20 male subjects aged 18 to 19 years of age, who were informed beforehand of the assessment procedure. These subjects were given instructions to hold at least 8 hours of quietude the night before the experiment, and were told to be present for the assessment on an empty stomach. These subjects were besides non allowed to consume any other food or drink substances during the window compass point of testing, and the entire experiment was conducted on the same day in a 3 hour window (830am to 1130am). to each one subject was to consume 250ml of water (experiment control) and 250 of Red Bull.Also, to allow the substances to absorb into the body of the consumer, reaction tests were conducted nevertheless 45 minutes after consumption of the substance. Such variables were important to digest been kept in order to ensure that no other environment al factors or other chemicals being absorbed into the body entrust affect the experiment. The reaction speed assessment is conducted electronically. Each assessment consists of the subject concentrating on a yellow spot on the screen, which will turn red. Upon changing colour, the subject has to click using a provided mouse as strong as possible, and the reaction time is calculated electronically. Each assessment consists of 5 trials. A 2 sample t-test will be used to assess the if on that point is a significant battle in the midst of the reaction time of the subjects under the tempt of water, versus under the exploit of Red Bull.Research interrogative moodIs there a significant struggle between the reaction speed of 18-19 year old males under the influence of water and under the influence of Red Bull susceptibility Drink? Hypothesis I moot that the reaction speed of the subjects under the influence of Red Bull Energy Drink is shorter than under the influence of water. C onsidering how consumers drink Red Bull to pressurize themselves when feeling lethargic, or having difficulties focusing, Red Bull must have a significant effect on the bodys psychoactivity. I also believe that an increase in the chemical stimulants (taurine, glucuronolactone and caffine) as well as high sugar levels will cause an increase in psychoactivity indoors the consumers body due to the nature of the chemical stimulants.(A sample sign-up form can be found on the spare-time activity page.)Pre-Experiment Procedure2. time 250ml of water and pour it into the large cup.3. Repeat step 2 20 measure. This is to prepare the initial control for the subjects to consume.4. Give a cup to for for each one one subject. Subjects consume the 250ml of water at about 2 minute intervals from each other. Start the stopwatch once the showtime subject has begun drinking.5. Prepare a computer terminal with the reaction test given in the following link below. Instructions on how to conduct t he test are provided on-site. You may need a computer lab to carry out the test. Each test involves five trials. http//www.steriley.com/speed/6. When 45 minutes has passed, allocate the first subject to the computer. Instruct him/her to carry out the test. Assist any offer up who may require extra help.7. When the subject has realised the test, collect the results into a table. Allocate the next subject to begin the test. This step should be completed in exactly 2 minutes.8. Repeat steps 3-7 once more, that instead give each subject a can of Red Bull instead of water.Investigate How Red Bull Energy Drink Affects The Reaction Time of 18-19 Year Old Human Males. (Sign-up sheet)Details venue St Josephs Institution InternationalDate 11 June 2011Time 830am 1130am (please be punctual)Instructions (read carefully before signing up)* Volunteers must be male and between the ages of 18 and 19.** Volunteers must receive 8 hours of sleep before the experiment day.* Volunteers must not have consumed any food or drinks at least 3 hours before the experiment.* Volunteers are not to consume any food or drink during the experiment period.* Volunteers are not allowed to do any strenuous activities during the experiment period. This includes running, and other forms of exercise.Std. Dev 0.033 0.019 represent showing mean reaction measure of 20 males, ages 18-19 under influence of water and of Red BullFrom the graph, we can already infer that there is quite a large difference between the reaction times of the subjects under the influence of Red Bull as compared to water. The t-test to follow will show if this difference shown on the graph is a significant difference or not.T-testI will now use a t-test to prove whether there is a significant difference between the reaction times of an 18-19 year old male under the influence of water or Red bull. Null Hypothesis (H0) There is no significant difference between the reaction times of an 18-19 year old male under the influence o f either water or Red Bull Energy Drink. Alternate Hypothesis (H1) There is a significant difference between the reaction times of an 18-19 year old male under the influence of Red Bull Energy Drink as compared to water.WorkingFor this experiment, the degrees of independence is calculated to be 20+20-2=38. The t-value as provided by the GDC is 6.2966 or 6.30 change by reversal to 3 significant figures. The p-value as provided by the table is 1.684 (at 40 d.f) with a confidence level of 95%. 6.301.684,tp.The value of t is larger than p.The P-value as calculated by the GDC is 2.232737 x 10 -7 or 0.000000223 (3.s.f.)
