Reaction Time And Energy Drinks

answer metre And Energy DrinksThis extended essay is an investigation into response eras in antherals and womanishs and how they were disturbed by ruddy bruiser. The research pass was How remarkable is the reducing in reception judgment of conviction cod to crapulence bolshy diddlysquat, in anthropoids as comp atomic go 18d to females between the terms of 16-17.To answer this, a butt enddid examine was carried out to obtain the necessary information. The ruler couch examine was conducted development a group of 20 subjects (10 male and 10 female).The chemical substance reply clip of the subjects out front and laterwards(prenominal)wards(prenominal) imbibing departure tinkers dam were hence puzzle outd victimization the results from the ruler drop rill and the formula t = (2d /a). The incriminate data was thus analysed using the T- examination to see how important the inequality in chemical response prison term was onward and after in toxication crimson slob. This revealed that level though chemical reaction magazines in males bring down after consumption of rubicund diddlysquat, the reduction was non significant. young-bearing(prenominal) subjects marched greater decreases in reaction time after imbibing rosy diddlyshit even though on average their reaction times were slower than male reaction time. The T- psychometric test showed that in females at that place was a significant fight in reaction time in the lead and after insobriety carmine fuzz. in the end the mean reductions in reaction time for some(prenominal) males and females were compared using the T-test, which revealed that thither was a significant going in male and female reductions in reaction time. This leads to the conclusion that between the ages of 16-17, sanguine diddly precisely significantly make passs reaction time in females and not in males.Introduction look QuestionHow significant is the reduction in reaction time due to intake of blushing(a) hog, in males as compared to females between the ages of 16-17.It constitutes you wings this is the slogan for bolshie copper color, a popular cypher drink. The slogan suggests that violent diddly-squat improves ones over all told in all performance. chemical reaction time is one of the physical attributes fixed by blood-red diddlysquat. I wanted to investigate blushing(a) Bulls effect on reaction time and evaluate whether blushing(a) Bull really does give you wings. chemical reaction time is the time interpreted to respond to any disposed(p) stimulus. The reveal the reaction time, the less it is. Fast reactions are useful in many situations, for instance avoiding another car whilst driving, pick uping a falling glass and even in sport.Previous research into reaction time has found that Males and females primarily produce different reaction times with females alas having slower average times. (Der and Deary, 2006).Energy Drink s are beverages that have a gaining or stimulating effect. They are often advertised as performance enhancing, with benefits in bouncingness and reaction time. Red Bull is probably the most conspicuous energy drink. The quick ingredients in Red Bull include Glucose, Taurine, Glucuronolacton, Inosital, Niacin, D-Panto and thenol (Vitamin B5), pyridoxal HCL (Vitamin B6), Vitamin B12 and caffein. (Further details in appendix ii.). These chemicals affect the automobile trunks metabolic functions so that overall performance is enhanced.My approach was proveal in which the Ruler Drop Test (Coach, 1997) was used. supposalI conjecture that Red Bull lead pass water a decrease in reaction time in all subjects. This is due to the ingredients contained in the drink. Taurine and caffeine are the ii ingredients that affect the speed of reaction most. Taurine improves nerve transmission this means that assumements make will be faster. Caffeine boosts adrenaline levels which makes one more(prenominal) alert and whence more likely to respond faster. Thus, I forestall reaction time to decrease in all subjects. I to a fault guessworke that the improvements in reaction time will be more significant in females as they generally have a smaller body mass meaning that the active ingredients in Red Bull will have more of an effect.ExperimentTest proceeds SelectionIt was central to make sure that the results from the experiment were as reliable as possible.To do this I had to choose test subjects (participants in the experiment) who were homogeneous in age, athleticism and how frequently they take energy drinks. I decided to use subjects deep down the age range of 16-17 as this is the age range with the most passel in my school and therefrom there was a larger test subject range. I had to keep the ages similar because age was found to have an effect on reaction time. (Gorus et al., 2008) Generally reaction time decreases with age until a certain point where it be gins to increase once more. I wanted subjects who were similar in athleticism because people who are more athletic are more likely to have quicker reaction times than non-athletic people. (Levitt and Gutin., 1971) I also needed subjects who didnt take Red Bull as frequently. It was mistaken that people who take energy drinks frequently may develop guard to its effects.A questionnaire was used to identify the subjects that fit in with these criteria. It was given to 40 people out of whom 10 males and 10 females were selected using random sampling. provision of fontsThe test subjects had to be prepared earlier the experiment to ascertain that it was in fact the Red Bull that was affecting the subjects reaction time and not any other food. The Red Bull was administered an hour after perish time. It was assumed that by this time all food (if any) would have been digested. This was classic because the Red Bull has to be the nevertheless substance ingested prior to the experiment t o make sure that the results obtained are from the effects of Red Bull and not any other food substance. Testing alikek place 10 proceedings after consumption to give the active ingredients in the Red Bull enough time to be assimilated.ProcedureThe Ruler Drop Test was carried out using the following method acting.A ruler was held so that it was between the index finger and thumb of the subjects stronger hand. The top of the subjects thumb was kept in line with the zero centimetre line on the ruler. The subject then tried to catch the ruler after it was let go. The distance from the toilet of the ruler to the top of the subjects thumb was recorded. To improve reliability of the results the experiment was resort once again. It would be nearly impossible to manually record the time taken for someone to catch a dropped ruler because this happens very quickly. So to calculate the time taken (and thus reaction time) the following formula was used.t = (2d /a)This was derived fromd = vt + at 11d is infinite mensurable in (cm)v is Initial velocity which is zeroa is Acceleration due to gravitational force this a constant jimmy of 981cm/st is quantify measured in seconds (s)Data CollectionThe tables below show the results from the ruler drop test conducted on 9.7.2010. It shows the distances that the ruler travelled before it was caught by the subjects. The results before and after deglutition Red Bull were recorded. The experiment was recalled double to improve the reliability of the results. streak 1Trial 2MalesFemalesMalesFemalesSubject numberDistance in the inaugural place imbibing Red Bull +/-0.05 (cm)Distance later boozing Red Bull +/-0.05 (cm)Distance Before crapulence Red Bull +/-0.05 (cm)Distance aft(prenominal) Drinking Red Bull +/-0.05 (cm)Distance Before Drinking Red Bull +/-0.05 (cm)Distance After Drinking Red Bull +/-0.05 (cm)Distance Before Drinking Red Bull +/-0.05 (cm)116131699612215141517128935930177517489221185135151118126715612719191 0711767151198168148171011610976141258121014171410131515Data ProcessingThe cutting data was processed to give the tables below. The determine in red show anomalies, that is data that is erroneous and/or unexpected, in this persona distances increasing after taking Red Bull and Reaction clip increasing after taking Red Bull. These reputes could be generated by an error in the data collection or an error in the experiment. They are thereof ignored when considering the significance.The tables below show the calculated reaction time before and after intoxication Red Bull. Reaction times were calculated using the distances obtained from the experiments which were then substituted into the formula. t = (2d /a).The tables also show the difference in reaction time which is the reaction time after deglutition Red Bull, subtracted by the reaction time before deglutition Red Bull. This was done so that that the improvement in reaction time can be seen. turn off (1.a) shows the data fr om the 1st repeat and table (1.b) shows data from the second repeat and Table (2) shows the mean of both repeats. In this table, most of the errors disappear as the mean uses the data from both sets of repeats to show an average or trend.Examples collusive Reaction TimeA subject catches the ruler at 16.0 cm without drinking Red Bull. The subject then catches the ruler at 13.0 cm after drinking Red Bull. The time taken for the subject to catch the ruler is worked out like this.Distance before taking Red Bull= 16.0 cmFormula t = (2d /a)So216.0= 3232/981= 0.03262 0.03262= 0.18061 therefore it took the subject 0.18061 seconds to catch the ruler before drinking Red Bull.Distance after taking Red Bull=13.0 cm213.0= 2626/981= 0.026500.02650= 0.16280Therefore it took the subject 0.16280 seconds to catch the ruler after drinking Red Bull.Calculating lossThe subjects Reaction time before drinking Red Bull is 0.18061 seconds and the subjects reaction time after drinking Red Bull is 0.16280 se conds.To hear the difference the subjects reaction time after drinking Red Bull is subtracted by the Reaction time before drinking Red Bull to give -0.01781.In this example, the calculated difference in reaction time is negative. This shows that after drinking Red Bull, the subjects reaction time improved by -0.01781 seconds.Calculating the MeanIn the second repeat of the experiment the subject catches the ruler at 9 cm before drinking Red Bull and then catches the ruler at 6cm after drinking Red Bull. The subject therefore gets these reaction timesBefore drinking Red Bull 0.13546 sseconds.After drinking Red Bull 0.11060 seconds.The mean for reaction time before and after drinking Red Bull can be calculated, using the values from the 1st and 2nd repeats of the experiment.Mean reaction time before drinking Red Bull0.18061 + 0.13546= 0.316070.31607 / 2= 0.158035 secondsMean reaction time after drinking Red Bull0.13546 + 0.11060= 0.246060.24606 / 2= 0.12303 secondsThe mean shows a mor e reliable value from both repeats.Table (1.a) Table of results from the first rivulet of the experimentTrial 1MalesFemalesSubject numberReaction Time Before Drinking Red Bull (s)Reaction Time After Drinking Red Bull (s)Difference In Reaction Time +/- (s)Reaction Time Before Drinking Red Bull (s)Reaction Time After Drinking Red Bull (s)Difference In Reaction Time (s)10.00580.0052-0.000570.180610.13546-0.0451520.00560.0054-0.000190.174870.186170.0112930.00320.00430.00110.247310.18617-0.0611440.00410.00430.000250.211780.14975-0.0620350.00560.0048-0.00080.191570.15641-0.0351560.0050.0038-0.001180.196810.19681070.00350.00380.000280.174870.14975-0.0251280.00540.0041-0.001320.186170.14278-0.0433890.00380.0035-0.000280.168940.15641-0.01253100.00540.00590.000550.168940.14278-0.02616Table (1.b) Table of results from the first trial of the experimentTrial 2MalesFemaleSubject numberReaction Time Before Drinking Red Bull (s)Reaction Time After Drinking Red Bull (s)Difference In Reaction Time ( s)Reaction Time Before Drinking Red Bull (s)Reaction Time After Drinking Red Bull (s)Difference In Reaction Time (s)10.135460.1106-0.024860.156410.174870.0184620.156410.12771-0.02870.135460.11946-0.01630.119460.10096-0.01850.186170.16894-0.0172240.127710.10096-0.026750.16280.13546-0.0273450.11060.119460.008860.174870.1628-0.0120860.142780.11946-0.023320.149750.11946-0.0302970.135460.12771-0.007750.180610.17487-0.0057480.149750.1106-0.039150.142780.13546-0.0073390.100960.127710.026750.156410.14975-0.00666100.16280.174870.012080.174870.1628-0.01208Table (2) Table of mean values from trial 1 and trial 2Trial 1 + Trial 22MalesFemalesSubject numberReaction Time Before Drinking Red Bull (s)Reaction Time After Drinking Red Bull (s)Difference In Reaction Time (s)Reaction Time Before Drinking Red Bull (s)Reaction Time After Drinking Red Bull (s)10.00510.0044-0.000650.168940.1564120.00530.0048-0.000520.156410.1564130.00350.00380.000280.218880.1777740.00410.0038-0.000260.188890.1427850.00470.0 043-0.000350.183410.1596460.00480.0038-0.000970.174870.162870.00390.003900.177770.162880.00510.0038-0.001280.16590.1391790.00350.00380.000280.16280.15312100.00530.00580.000470.171940.15312Data analytic thinkingThe first step in analysing the data is to compare the reaction times of males and females before and after drinking Red Bull separately using the mean values from table 2. This is done belowGraph (1.a)The graphical record (1.a) shows the parity of the mean male reaction time before and after drinking Red Bull. The graph shows that generally the blue break off (Male Reaction Time before Drinking Red Bull) is higher than the red bar (Male Reaction Time After Drinking Red Bull) This suggests that Red Bull generally had the effect of reducing reaction time in males.Red Bull contains Taurine (see appendix ii) Taurine speeds up neural transmission, so nerve impulses are passed along through the nervous system more than faster. This means that the time taken for the subjects ha nd to react to the stimulus (in this case the dropped ruler) is less. some other ingredient that probably affects reaction time most is caffeine. Caffeine blocks adenosine and boosts adrenaline levels. Adrenaline causes the heart rate to increase, the respiratory rate in the lungs to increase and muscle contraction all around the body. These are incisively some of the effects know as the fight or dodging response. The overall effect is that you respond better to stimuli as the body is more alert.T TestThe T-Test shows how significant the statistical difference between two values is. The T-Test determines the P-Value. In Biology the difference between the two values is considered statistically significant if the P value is below 0.05 If it is The zip supposal is therefore rejected and the alternative hypothesis is accepted.Null Hypothesis There is no significant difference in reaction time before and after drinking Red Bull in Males.Alternative Hypothesis There is a significant difference in reaction time before and after drinking Red Bull in males.For this T-Test I compared the mean values of reaction time before and after drinking Red Bull for males. I got a P-Value of 0.06626028. This is greater than 0.05 therefore the Null hypothesis has to be accepted.The T-Test suggests that with males, the difference in reaction time after drinking Red Bull is not significant because the P value (0.06626028) is greater than the standard critical value (0.05).Graph (1.b)The graph (1.b) shows the comparison of the mean female reaction time before and after drinking Red Bull. Again, the graph shows that generally the blue bar (Female Reaction Time after Drinking Red Bull) is higher than the red bar (Female Reaction Time Before Drinking Red Bull) This suggests that Red Bull generally had the effect of decreasing reaction time in females. This decrease is again due to the ingredients contained in Red Bull. Both taurine and caffeine affect the subjects system so that the speed of movement and response in increased.T-TestAnother T-Test is carried out to find out how significant the difference in reaction time before and after drinking Red Bull in females is.Null Hypothesis There is no significant difference in reaction time before and after drinking Red Bull in Males.Alternative Hypothesis There is a significant difference in reaction time before and after drinking Red Bull in males.For this T-Test I compared the mean values of reaction time before and after drinking Red Bull for females. I got a P-Value of 0.00068587. This is less than 0.05 therefore the null hypothesis is rejected and the alternative hypothesis is accepted.The T-Test suggests that the differences in the female reaction time before and after drinking Red Bull are very significant as the P value (0.00068587) is far below the standard critical value of 0.05.The last(a) step in analyzing the data is to compare male and female replace in reaction times.Graph (2)Graph (2) shows the Com parison of Male and Female reduction in reaction time. The pink mend points show the mean female difference in reaction time whilst the blue plot points show the mean male difference in reaction time. The graph shows that generally mean male reduction in reaction times were much lower than the mean female reduction in reaction time. This suggests that females are affected more by Red Bull. Another musing that can be make from the graph also shows that the female data is more varied than the male data. However the data that was collected was too small to make any definite conclusions.T-TestA T-Test was carried out to find out how significant the difference in mean male and female difference in reaction time.Null Hypothesis There is no significant difference between mean male and female difference in reaction time.Alternative Hypothesis There is a significant difference between mean male and female difference in reaction time.In this T-Test I compared the mean values of difference i n reaction time for both males and females. I got a P-Value of 0.001571698. This is less than 0.05 therefore the null hypothesis is rejected and the alternative hypothesis is accepted.The T-Test suggests that there is a big significance in the difference between mean male and mean female difference in reaction times because the P value is much lower than the critical value of 0.05.ConclusionIn general, reaction times decreased after drinking Red Bull in both males and females. Males generally had faster times females. However the T-Test shows that in males this difference is not significant whilst in females, it is quite significant. Further calculations showed that there was a significant difference between the reduction of reaction time in males and females. Females generally had greater reductions in reaction time.The data does not support the first hypothesis, which states that reaction time would decrease in all subjects after the consumption of Red Bull, as there were some ins tances where the reaction times worsened. These anomalies may have been due to error in the method however, and had no overall significance to the experiment as they were ignored.The data supports the utmost hypothesis, which states that Red Bull would improve reaction time more significantly in females. The results from the investigation show that females had a more significant reduction in reaction time after drinking Red Bull as compared to males. The reason for females being affected more by Red Bull is, Pound for pound females have less water in their bodies than men, so their body parts are more exposed to the active ingredients in Red Bull. This leads to the conclusion that between the ages of 16-17, Red Bull only significantly reduces reaction time in females and not in males. military rankThere were some aspects of the experimental method that may have reduced the reliability of the data.When the ruler drop test was performed for the second time the subjects alternatively of improving reaction time as a result of drinking Red Bull may have naturally improved their reaction time through practice. Also the subjects knew that they were drinking Red Bull and that Red Bull is said to improve physical performance including reaction time. This again may have caused them to improve their times naturally through the mental stimulation.There is no actual proof however that improvement in reaction time was due to practice. It is only a speculation. However if the subjects reaction times were improving as a result of practice then this would affect the data as Red Bull would not be the only factor improving reaction time. The best way to reduce the effect of this factor would be to carry out the experiment only once. This would reduce the reliability of the data as a mean of both experiments not would be possible to calculate but at the selfsame(prenominal) time it would improve the reliability of the data as subjects would not be getting better with practic e and it would be only the Red Bull affecting the subjects reaction time.I also could have set up another Ruler Drop Test experiment using a different set of subjects but replacing the Red Bull energy drink with a non energetic drink. The subjects however, would be told that they are having another spot of energy drink. This would test the thought of having an energy drink makes the subject expect to perform better and therefore actually improving their reaction time naturally. A second experiment using the same subjects could then be carried out using but using Red Bull. The results of the second experiment could then be compared with the results from the first experiment to further asses the significance improvement in reaction time due to Red Bull.Error analysis30 cm Ruler (cm)Absolute uncertainty+/- 0.05Percentage dubiousness %0.25Overall Uncertainty %0.25Appendix (i)QuestionnaireHow old are you ____2.

The body uses glucose in respiration to make energy.C6H12O6 + 6O2 = 6H2O + 6CO2 + 36ATPGlucose + Oxygen = Water + nose candy Dioxide + Energy.Redbull contains 5.25 g of glucose.TaurineTaurine is an amino acid that is usually made in the body. Each can of Red Bull contains 1000mg of Taurine. Taurine helps move minerals like potassium, sodium, calcium and magnesium through the cells. This helps to generate nerve impulses therefore making neural transmission faster.GlucuronolactonGlucuronolacton is a chemical similar to taurine. It affects retention and concentration in the brain. It is known to have effects similar to anti-depressants and stimulants.InositalInosital is a chemical that has a mood boosting effect and it maximises the brains uses of a serotonin a chemical that is found in most anti-depress ants.NiacinNiacin is a B vitamin that helps in energy formation. It metabolizes energy from fat and carbohydrates. Niacin can help the body use energy by releasing it from food.D-PantothenolD-Pantothenol is also known as vitamin B5, or Pantothenic acid. It is known to improve mood and boost energy. D-Pantothenol help turn fat into energy and increases metabolism.Pyridoxine HCLAlso known as Vitamin B6, Pyridoxine HCL helps red blood cells to form and provides better oxygen utilization. It also help to break down sugar that you have stored in your body to use for energy.Vitamin B12B12 helps in the formation of red blood cells, for better oxygen utilization. It also help with energy production by suspension down fat and protein.CaffeineRed Bull contains 80.0 milligrams of caffeine which is closely double the amount of all other soft drinks. The caffeine in Red Bull gives you energy by blocking a chemical in your brain called adenosine. Adenosine promotes sleepiness and without it yo u would not be able to fall asleep. When adenosine is blocked you body releases a boost of adrenaline which wakes you up.
