Query: Does the caffeine in Skol affect stress? Hypothesis: How much caffeine in Coca-Cola may cause to the adrenal glands, situated on the top of the kidneys, to release more adrenaline that can in turn trigger an increase in blood pressure. As how much Coca-Cola diminishes, so will the difference between initial blood pressure and blood pressure after the usage of the caffeine. Variables:
Independent Variables| Dependent Variables| Controlled Variables| Amount of Coca-Cola consumed for each trial: * 500mL * 400mL * 300mL * 200mL * 100mL| Blood Pressure after consumption of caffeine. | Blood Pressure pre-consumption of caffeine.
Blood Pressure Cuff and BulbCoca-Cola
Procedure: To be able to test my own hypothesis, I decided to use a prevalent caffeinated refreshment, Coca-Cola. The quantity of caffeine in each jar is given because 48mg/500mL. Therefore , to keep my personal calculations clean my first test was with 500mL of the Skol. I had taken my blood pressure with a Vermier Labquest before I consumed any caffeine to have a control variable. It had been a manual blood pressure screen, so I got my own stress. After putting your cuff in the arm, My spouse and i squeezed the bulb until the cuff pressure reached 170 mm Hg. Then, My spouse and i released the bulb and let the pressure drop until it was 50 logistik Hg and i also used the discharge valve within the bulb to fully release the pressure and stopped your data collection. This kind of data was recorded. Next, I measured the quantity of the Coca-Cola used for the existing test into a measuring cup and then consumed it. I waited twenty minutes after consumption to take my blood pressure again. Caffeine has been reported to take have an effect on after a time length of 15-45 minutes.
