Caffeine as a supplement
I
have chosen to do my blog article on caffeine. Caffeine is a natural
component in coffee, tea and chocolate. It is also an ingredient used
in sport drinks and soft drinks.
“caffeine
is a central nervous system and metabolic stimulant and is used both
recreationally and medically to reduce physical fatigue”
when
caffeine is in the body, blood vessels contract where its not
required, example: stomach. Because caffeine is a stimulant it
increases blood pressure, heart rate and blood vessels around the
heart and brain dilate.
When
caffeine is ingested it is quickly absorbed by the body. Consuming 1
hour before exercise can help enhance endurance and provides a small
but worthwhile effect on performance. It is also known that caffeine
increases muscle contractions.
Caffeine
can be consumed in many ways due to the fact that a lot of products
contain caffeine. The correct way would be to purchase drinks that
contain caffeine. Most caffeinated drinks contain between 30-100mg of
caffeine per serve. People can also buy non-prescriptive caffeine
tablets, they can contain 100-200mg of caffeine per tablet.
Side
affects of caffeine is different for every individual. Some people
may not be affected by it, and other can experience headaches,
increased heart rate, excessive urination and difficulty sleeping,
there are many more side effects that is associated with caffeine.
“caffeine
has been found to help with two kinds of exercise: endurance
activities like marathon or iron man competition, and short, power
intensive activities lasting about 4 to 8 minutes”
