Question: what is the effect caffeinated energy drinks have on both reaction time and heart rate in sports men and women?
Hypothesis: Caffeine will increase the heart rate
Aim: To test how caffeinated energy drinks affect the reaction time and heart rate of sports men and women.
Apparatus:
• Caffeinated energy drink ( Monster – sugar free )
• Ruler ( 30cm long )
• Timer ( to measure heart rate )
Method:
• The test subject will have their heart rate recorded (BPM) when under no influence of sugar or caffeine. The environment will be that of a relaxed environment with no distractions and no unnecessary sounds or music.

Chosen gender and age of test subject
2. Ruler used throughout all tests are the same
3. Person dropping the ruler is kept the same
4. Caffeine content of energy drink
5. Content of zero sugar in energy drink
6. Energy drink and volume consumed by each test subject is kept the same
7. Time taken after consuming energy drink being kept the same
Dependent:
1. Heart rate recorded (bpm)
2. Reaction space (cm)
Generally affecting variables:
1. The distraction of music or any sounds that could remove concentration of the subject rendering the test unfair.
2. The weather could affect the heart rate of the subject.
3. The other ingredients in the energy drink like guarana that is a natural energy booster.

If the effect is severe enough these changes could lead to an irregular heartbeat. There seven studies being reviewed in which people between the ages of 18 and 45 were tested showed; those who consumed energy drinks had experienced a 4 percent change in the rhythm of their heart. The changes could be interpreted as small, but if someone who has an existing heart problem, or who come from a family with history of heart problems, they should really cease in drinking these highly caffeinated energy drinks. The side effects to look out for even if you are a healthy individual when drinking these energy drinks
