The Effects of Energy Enhancers on pulse and blood pressure
Introduction
Question
Is there a significant difference in blood pressure and pulse before and after the consumption of difference performance enhancers?

Hypothesis Pulse After Jumping Jacks/Skipping Rope
Bottled Water After the consumption of bottled water, the heart rate will indicate that there is an increase in cardio vascular performance as water helps transport oxygen in the blood where it is needed by the cells.
Original Gatorade After the consumption of Gatorade, the heart rate will indicate an enhancement of physical activity as Gatorade provides electrolytes that help hydrate the body.
Original Coke
Original Red Bull After the consumption of Red Bull, the heart rate will not indicate any significant difference as the ingredients would not help catalyze any physical effects.
Original 5-hour Energy After the consumption of 5-hour Energy, the heart rate will indicate that there is an increase in cardio vascular performance as 5-hour Energy is promised to provide an increase in energy and in its list of ingredients is caffeine, which would increase heart rate.
Black Coffee

Null Hypothesis
There is no significant difference in the results of cardio vascular performance after the consumption of certain performance enhancers.

Variables
Independent Variables: The types of energy enhancers
Dependant Variables: Heart-rate before and after the consumption of energy enhancers, blood pressure before and after the consumption of energy enhancers
Controlled Variables: Bottled water as an energy enhancer, length of time sitting, time of the day, location, type of clothing, temperature, amount of energy enhancers
