Effects of Caffeine on Cyclist Performance: Research Based Evidence

This research investigates the effects of caffeine on cyclist performance and whether it is dose dependent. It explores the benefits and drawbacks of caffeine intake, and provides evidence-based recommendations for cyclists. The study is based on a scenario where a cyclist wants to reduce trial time by consuming caffeine prior to a race.

1. Scenario # 1
The research is based on scenario 1 where Martin my friend wants me to conduct a research
on the effects of caffeine in reduction of time trial or the time used to finish a cycling race.
Martin is cycling for a local club championship cycling club and is motivated to improve his
performance. He trains regularly and follows a very strict and healthy diet (Black, et al,2015).
However, besides this, he wants to reduce the trial time by consuming caffeine prior to any
race and has had that the product is beneficial. Other members of the cycling club have also
had the effect of caffeine. Martin wants me to research on the effects of caffeine on
performance and if it is dose dependent. This is a great to undertake a great research on the
effects of caffeine on performance especially in cycling.
2. My answerable question
The answerable question in the research is the effect of caffeine on the performance of a
cyclist and whether the performance is dose dependent.
Over-break is a tradition of many cyclists. Coffee making options are huge, so what is the
most useful?
Caffeine is an integral part of the cyclist's diet. It stimulates the central nervous system,
which contributes to the release of adrenaline and a surge of energy. This is ideal for people
participating in endurance sports (Brownson,et al,2017).
Caffeine in itself speeds up the metabolism and stores muscle glycogen, so black coffee

excessive use of caffeine can disrupt the quality of sleep, which, in turn, can lead to hormonal

disruption, metabolic disorders, and cause a number of diseases. Be careful with caffeine, so
as not to hurt yourself.
But what is the best way to make coffee and when to drink it? Double espresso before the trip
gives a powerful boost of energy. Caffeine stimulates the system, but without milk it can
harm the stomach. Americano with sugar and silent milk is also a great option. ”It will give
energy without causing any discomfort in the stomach (Doering, et al, 2014).
After the trip, you can drink a drink with milk in order to recover. You can choose a latte or
mocha with skim milk, extra calories to anything. So the body will receive the necessary to
restore the amount of protein, calcium and fat.Different varieties of coffee beans have more
or less acidity. It is not recommended to drink strong coffee drinks during a trip for people
who have an increased sensitivity of the stomach.
As a rule, grains grown in higher localities, for example, in high altitude areas, have a more
sour taste than those grown on flat low altitude plantations. In addition, it is necessary to pay
attention to the color of the grains - the darker the better (Glaister, et al,2015). Saturated dark
color is achieved by deep roasting, which simultaneously reduces the sour taste.

4. Database
Yes. The database in our research shows that there is a positive increase in performance of a
cyclists and the intake of caffeine. This is because, caffeine stimulates the cyclist’s mental
wellness first. The people in the research said that one feels a little bit smarter and a little bit
stronger. There is valid evidence that caffeine greatly improves the muscle contraction
(Noble, & Smith, 2015).
Our database shows that caffeine has a lot of glycogen sparing effect. Glycogen is the storage
molecule that stores carbohydrates that is then converted into energy when a cyclists starts to
exercise. If we don’t replace caffeine into our body we don’t have to replace it but we can
ingest more carbohydrates.

RESEARCH EVIDENCE
5. Reflection
By taking in caffeine, we start to use it when we exercise. The caffeine taken has the ability
to breakdown fats instead of breaking glycogen. It means that a cyclist’s body has more
carbohydrates that is available for longer if we don’t take in caffeine (Royse, Thyer , &
Padgett, 2015).
In the final stages of a race, a cyclists that has taken caffeine is not glycogen depleted and one
has still got some sugars from the carbohydrates that is stored in the muscles and in the liver
that is ready to be used.
