Is caffeine beneficial for Endurance Performance?

May 26, 2022

Is caffeine beneficial for Endurance Performance?

Caffeine is a well-established performance booster. Is it beneficial for endurance performance? Heck yes!

But more does not equal better when it comes to caffeine supplementation. It’s about finding the lowest dose to give the greatest effect, without the negative effects. It’s also about finding out what’s best for you and your specific training and racing needs.

How is caffeine absorbed?

  • Rapidly – can be seen in the blood in 5 – 15 minutes
  • Peaks between 40 – 80 minutes
  • Maintained for 3 – 4 hours
  • Half life 3 - 5 hours
  • Is transported to all body tissues and organs

How does caffeine work?

  • Stimulant - physiological and psychological effects
  • Mechanism not fully understood
  • Crosses the blood brain barrier - main action is stimulation of the central nervous system
  • Lowers perception of effort
  • Reduces pain 
  • Improves performance 
  • Think of caffeine as a chemical that keeps the on switch on and blocks the handbrake

What are the negative effects of too much caffeine?

  • Increased HR
  • Anxiety
  • Over arousal
  • Impaired fine motor skills (shakiness)
  • Sleep disturbances
  • Gut upset

Where else can you get caffeine from without needing to use tea and coffee?

  • A product I like to use is Revvies – a wafer strip that dissolves on your tongue 
  • Good if you just want caffeine – but don’t want/need to fuel, drink
  • Mint flavour refreshes a manky mouth 
  • Available pretty much worldwide – revvies.energy.com*

 

Important things to consider 

* Caffeine supplementation shouldn’t be considered for younger athletes.

* Caffeine is not a substitute for quality training and race experience.

* Caffeine is not something you want to muck around without getting individual advice.
