How Do Sports Drinks Affect Someone's Performance

Purpose: My idea for this lab occurred one day when I wondered if a sports drink could actually affect someone’s performance and possibly improve it or could this just be a marketing ploy to get athletes to buy their drink. I personally enjoy running and personal fitness and I do not think that sports drinks affect me before a run or weight training so I decided to test and see the results. If the tests show that it improves performance I may want to start drinking sports drinks to enhance myself during these activities.

Background: This lab is designed to test if a sports drink is more efficient at lowering blood pressure than regular water. Sports drinks are beverages that are intended to help athletes to replace water, energy, and electrolytes before and after activity. Electrolytes are substances that aid to trigger and sustain the heart’s electrical impulses. Some electrolytes found in the blood that are vital to the function of the cells …show more content…
My data shows that the trials without liquid had an average percent change of -76% for heart rate, an average percent change of -74.25% for the trials with water and a percent change of 43% for the trials with Gatorade. This data shows that the sports drink has a greater effect on lowering heart rate during exercise than only water. It seems that my hypothesis was proven correct in that the sports drink with electrolytes did have a greater effect on heart rate and blood pressure, although I did not expect such a great difference in statistics. In conclusion sports drinks with electrolytes do actually make a big difference in lowering the heart rates of athletes and thus could lead to better performance from those athletes. A follow up experiment could be preformed with different sports drink brands to see if one could lower the heart rate of the participant more

    Goldfish Metabolism

    In a separate beaker of 200 ml of fish water, a 50mg caffeine tablet was dissolved. To accurately test the effect of caffeine on oxygen consumption, the same two fish were used for both the control and experimental trials (Trial 1). After receiving our data from LoggerLite and transferring it on an Excel sheet, 100mL of fish water was removed from the oxygen chamber and 100 mL of caffeine-treated fish water was added to the chamber. Once the plunger was placed back on the oxygen chamber, the fish were left to acclimate to their new environment for 3 minutes. As soon as the fish were acclimated, LoggerLite began taking new measurements of oxygen consumption in 20 second intervals.…

    Caffeine Experiment

    We chose to conduct this experiment because both Amber and I are interested in athletics and the science side of it. There have been several researchers studying the effects of caffeine, and they believe it can enhance athletic performance and agility in sports. Because of this we believe if caffeine levels are increased, then time taken to run a lap will decrease when time is a function of caffeine level. To test this we will have a group of ten subject male and female who around the same athletic capabilities. Then, we will give them a set volume of liquid at different caffeine levels to see if the subjects running time changes with the caffeine.…

    Energy Drinks: The Side Effects Of Energy Drinks

    The risks associated with energy drinks are believed to be higher for people who already have existing medical conditions, such as heart defects or certain heart conditions. For example, people with “hypertrophic cardiomyopathy” (seconds count1) should never have caffeine or other stimulants, as they may increase the risk of irregular heart rhythms, high blood pressure, and can cause sudden death from cardiac arrest. It is very important to note that not all heart defects are discovered before or when a child is born. Some people may have structural defects in the heart that go undiagnosed until later childhood or…
