3

• Caffeine binds to the receptors
• Brain
• Heart
• Skeletal Muscles
• Fat cells

4
Absorbed by the stomach and small
intestineTransmitted through the bloodstream to
the brainAffects the Central Nervous System
5
Caffeine binds to the ATP receptors without
activating the ATP (Antagonist)
6
With caffeine bonded to the receptors

• Messages are sent to the brain
• More alert
• Relays a sense of being energized
• Improves concentration
• Speeds reaction time
• Power is elevated for longer without
  feeling like you are working harder

7
Highest amount of caffeine is found in the
skeletal muscles.

• Glucose energy
• Oxidized in cell respiration to carbon dioxide
• and water
• Produces energy in the form of ATP
• Extra glucose stored in the cells as glycogen

8
Muscles need energy to contract

• Glucose is depleted by exercise
• Body turns to fat for fuel
• Caffeine releases fat storage while storing up to
  50 of its glucose
• With glucose stored, the body utilizes the fat
  for fuel.
• Lactic acid build-up is delayed
• Allows for longer exercise

9

• Anxiety
• Restlessness

• Depression

12
Positive effects for the athlete

• Stimulates the heart, respiratory system
• Increases blood circulation
• Raises blood pressure
• Helps to prevent dehydration

13
Conflicting DataCaffeine does not alter fluid
balance, sweat rate, total water loss and does
not increase heart rate in exercise.
14
Research indicates caffeine may benefit in
preventing heart disease or at least lower the
incidence of heart disease
15
The amount of caffeine ingested, the body weight
and, how often it is consumed can determine the
effects it has on the athletes performance.
16
