Motivation: I chose this topic because I am a competitive swimmer and i 'm always looking for ways to improve my swimming speed in the most efficient way. Aim: To find an effective way to swim faster and how the supplements contribute to your speed and heart rate and to understand the affect of energy drinks on a …show more content…

- 500ml of Red Bull. - 3-5 Individuals = swimmers. Literature Review: Red Bull may give you more energy for a short amount of time, the caffeine in Red Bull will absorb into your bloodstream while your body responds by increasing your heart rate and blood pressure. While Red Bull increases your energy it will allow you to swim fast at the start of the 50m sprint but your speed will decrease as the energy is being absorbed Taking no supplements will keep your heart rate and energy at its normal levels, thus providing you with no extra energy to sustain you for the entire 50m sprint, which will result in your speed being faster at the beginning but decreasing at end speed due to your energy being used with no extra energy to sustain for the rest of the sprint. The result will either be the same or lower than the Red Bull. Chart representing average heart rates: - Female (bpm) Excellent: 61 -65 Average: 74-78 Poor: 85+ - Male (bpm) Excellent: 56-61 Average: 70-73 Poor: 82+ Conclusion: Red bull increased the heart rate drastically but did not make the swimmer swim much faster thus Red Bull would not be a good stimulant for speed

To Study The Effect Of Daphnia And Stimmutant

melatonin and ethanol, will produce a depressant effect on cardiac activity, i.e. decrease HR. It is predicted that stimulant chemicals, e.g. epinephrine and dopamine, will produce a stimulant effect on cardiac activity, i.e. increase HR. It is predicted that the two stimulant, when administered together, will produce a synergistic effect on HR, i.e. increase HR more than in comparison to when administered individually. Additionally, the two depressants, when administered together, will produce a synergistic effect on HR, i.e. decrease HR more than in comparison to when administered individually. Lastly, when the depressant and stimulant are administered to the Daphnia magna in combination, an antagonistic effect will be observed, i.e. the depressant and stimulant chemicals will negate each other resulting in HR within 5% deviation of the base line daphnia

Daphnia Heart Rate

My group recorded higher heart rate compare to the class average when we used caffeine on the Daphnia as seen in Figure 2. Several errors could have accounted for this data. This including perhaps the Daphnia’s heart rate may have changed because of fear while being moved from the bowl to the microscope slide. Another possible error could have also been the amount of time that it took to change the solutions, which could have accounted for slight variations in heart rate. Temperature is yet a further error to account for as the microscope slide temperature was constantly changing to view the specimen, and change the dosage of caffeine or alcohol.

Goldfish Metabolism Experiment

1468 Words | 6 Pages

Introduction Metabolism is the sum of all anabolic and catabolic reactions within a living organism to sustain life. The energy required to perform these reactions is provided by oxygen in the form of ATP, therefore the oxygen consumption rate can be measured to determine the metabolic rate. Since oxygen is obtained through respiration, the efficiency of an organism’s respiratory system affects its metabolism. Previous studies have shown that caffeine affects the human respiratory center and occasionally dilates bronchus. It can thus stimulate human respiration and increase the metabolic rate (Haggins et al, 1915).

Orange Juice Vs Sports Drinks Essay

898 Words | 4 Pages

Sports drinks high in sodium, potassium, magnesium, and calcium can help retain fluids, and proper fluid balance contributes to optimal performance. Sodium is the most important electrolyte to monitor during exercise or play. High losses of sodium, typically through sweat, can lead to muscle cramps, which can lead to decreased performance and possibly more major health complications. Sodium losses in sweat are greater than any other electrolyte. Potassium, along with sodium helps prevent muscle cramps.

Electrolytes Experiment

If one compares the amount of electrolytes present in an artificial substance (sports drink), to those in a natural substance (orange juice), then the natural substance will have the most electrolytes. That is my hypothesis. I chose this topic because I have always been skeptical about the validity of the quantity of electrolytes said to be in sports drinks. Sports drinks have been recommended as a way to replace electrolytes, which are lost during exercise. However, orange juice also has electrolytes and these are naturally occurring, not man made.

Daphnia Experiment

This is due to caffeine, which is present in coffee, mimics the effects of the neurotransmitter adrenaline and noradrenaline in the heart. It can affect the main pumping chambers (ventricles) which leads to an increased rate of contraction and relaxation of each beat. This means the heart beats faster and an increased volume of blood pumped into the circulation per unit time (Handy, 2009). When yeast solution is added, the movement of the daphnia increased with a normal, steady-paced heart rate. This is because yeast is a form of food for daphnias which results in faster movements of the daphnia trying to capture and engulf the yeast particles in its limbs inside its carapace.
