Carbs and coffee refuel muscles faster

July 8, 2008 - 3:51PM

Drinking a cup of coffee with a plate of carbs will help athletes recover from their training sessions faster, Australian research shows.

Melbourne scientists showed that pairing caffeine with food dramatically boosts the body's levels of glycogen, the main fuel source for muscles.

The findings, published in the Journal of Applied Physiology, offer Australia's Olympic competitors a new way to power-up in preparation for the Beijing Olympic Games, says lead researcher Professor John Hawley, from RMIT University.

The research found athletes who added caffeine to their post-exercise meal had 66 per cent more glycogen in their muscles than those who ate only carbohydrates.

"If you have 66 per cent more fuel for the next day's training or competition, there's no question you'll be able to go further and faster," said Prof Hawley, who heads the university's Exercise Metabolism Group.

While it has been established that carbohydrates and caffeine improve a variety of athletic performances, this is the first study to show the combination can be used afterwards to help muscles refuel more rapidly.

The research involved four assessment trials with seven endurance cyclists who were given either a plain carbohydrate drink or one containing the caffeine equivalent of six strong cups of coffee.

The cyclists rode a cycle ergometer until exhaustion. Four hours later those who had consumed the drink containing caffeine had 66 per cent higher glycogen levels in their muscles compared to those who had the carbohydrate-only drink.

Prof Hawley said the research could help elite sportspeople looking for an edge over their competitors.

"But because caffeine can potentially have negative effects - such as disturbing sleep or causing the jitters - athletes who want to incorporate it into their recovery routines should experiment and see what works for them well before any serious competitions," he said.

Wow. I feel less guilty about having four coffees today.

Sorry for being a killjoy sceptic, I have to ask some questions:

How much caffeine is needed? 6 cups is a lot - will it work with one cup? Is the effect linear? is there a threshold amount needed?

Does the increase in glycogen levels reduce over time? For example, is it a 66% increase on the first day, but less on the second day, reducing to zero after a week?

I don't think the cigarette in the photo will help :)

This is great news, thanks Naomi

(my coffee machine will be fixed and coming back to me tomorrow, YAY)

I dispute the claim that drinking copious amounts of caffeine will make cyclists go faster.

You see, coffee is what's known as a diuretic. The effect of a diuretic is it makes people piddle more. Any gain in energy and speed by cyclists will be lost by having to run to the loo all the time!

Body builders recommend having at least one cup of black coffee before a training session because the caffeine gives you that extra kick that makes you work harder. I guess it's better than taking steriods.

Recovery is faster with the use of stimulants, of course. But there
are also all of the problems associated with stimulant use.

Adrenaline stimulates the production of insulin.

Science is good, coffee is better!! (and a muffin too thanks!) :)

I didn't really need scientists to tell me that coffee makes hills less traumatic!

bicycles+coffee=happy days!

Anyway those disgusting energy gels all you roadies have often have caffeine in them already so its not really new news.

Each morning when I get to work I have 3 to 4 instant coffees then an "extra large" quad shot cappuccino, then later in the day I have another large coffee. I like coffee :)

If you like it why do you subject yourself to instant ? ;)
