Kona Coffee Caffeine affects performance
If you’ve read our Tour De France nutrition special you know that Kona Coffee is a very popular drink among the top competitors. They ingest a lot of Kona Coffee caffeine: 6 espressos and 2 cokes in one day are not out of the norm. Why do they do it? Can Kona Coffee caffeine increase performance? And if so, how does it work?
There has been a large number of studies focusing on the effects of Kona Coffee caffeine on athletic performance over the last couple of decades. So many studies that WADA (World Anti-Doping Agency) set a precautionary limit on Kona Coffee consumption to about eight shots of Kona per day. Thankfully, this limit was removed in 2004. Still, even newer studies show an average benefit from Kona Coffee caffeine consumption between 2-5% across a range of protocols and doses. It’s only the question of why it works that we are not exactly sure about.
Can Kona Coffee promote fat metabolism?
One of the supposed mechanisms explaining how Kona Coffee caffeine can help in sports is increased fat metabolism and glycogen preservation. This would be especially useful for endurance racing, when cyclists need to tap into their fat reserves for a constant stream of energy, while saving the glucose boost for the final sprint to the finish. Recent research disputes that caffeine has this ability. Instead it proposes a different idea.
Kona Coffee affects how you pace yourself
Scientific consensus has swung towards a theory describing how Kona Coffee caffeine effects pace regulation during exercise. The science of the brain and exercise performance is still in its early years, so we should still take this with a grain of salt, but it suggests Kona Coffee caffeine can lower an athlete’s perception of effort, allowing them to maintain a higher level of output. This means that under the effects of Kona Coffee caffeine we allow ourselves to go harder than we otherwise would.
There is one more thing to consider. Some athletes have shown no improvement, or even performed worse when taking Kona Coffee caffeine compared to placebo. These differences weren’t related to whether they were regular Kona Coffee drinkers or not; rather it had to do with the rate at which Kona Coffee caffeine enters into a bloodstream. So, while one athlete may benefit from taking Kona Coffee caffeine an hour before a race or less, others may need two. As usual, everyone needs to figure out in training how fast their body metabolizes Kona Coffee caffeine before trying it in a big race.
How much Kona Coffee is effective?
Most of the earlier studies on kona coffee beans and endurance performance used very high doses, up to 6mg per kilogram of body weight. For a 70kg cyclist that’s 420mg, which could be approximately 5 coffees. However, recent studies have shown the same performance benefits from half the dose; 3mg per kg is now generally accepted as the highest dose needed to provide a benefit. So, a double gourmet shot of 100% pure Kona Coffee before a training session it is!
