Cycling research (Caffeine and Carbohydrate)

On behalf of Leeds Metropolitan University I am inviting you to participate in the study entitled 'The Influence of Carbohydrate and Caffeine Co-ingestion on Metabolism, Psychological Affect and Cycling Performance', which will form part of a Doctoral thesis.
As keen cyclists will know, nutrition is an integral aspect of performance. With races being won and lost by the smallest of margins, the optimisation of nutritional strategies during a race can make a significant difference to the outcome.
During exercise, the body's preferential fuel source is carbohydrate (CHO), therein lies the problem. Unfortunately, we have a limited ability to store carbohydrate in the body (liver and muscle glycogen), therefore limiting its depletion can help improve endurance capacity. Recently there has been growing interest in the use of caffeine and its effects on performance when co-ingested with CHO, but current evidence is contradictory and further exploration of the area is required.
From the results we are be able to provide detailed feedback regarding individual responses to each drink formulation and may be able to suggest nutritional strategies to help optimise your performance.
Further, each participant will undertake a continuous incremental exercise test to volitional exhaustion in order to determine your maximal oxygen uptake (VO2max) and cycling Power output (this test alone would cost in excess of £150 to external clients). The data obtained from this test can also be used to assign accurate training workloads, especially useful during the winter months when you may be resigned to indoor/turbo based sessions. This type of test is highly repeatable, meaning that we can detect meaningful changes in your fitness. Therefore, if you make changes to your training program, a repeat test would inform you whether the training intervention had been successful or not.
If you are a male cyclist/triathlete aged between 18 and 40 and are interested in participating in this study or would like some additional information please contact me at b.l.taylor@leedsmet.ac.uk
Thanks,
Ben.

Are you going to be testing gels or just drinks? In the States, not many of the energy drinks for endurance athletes are infused with caffeine but a large percentage of the energy gels are. Here is a chart of all the gels and their caffeine content. I'd be very interested in the results of your investigation.

If you are after guinea pig's put my name down0 -
You might put the "adults need not apply" qualifier at the top so we don't need to read the whole thing before getting to that bit..If you are a male cyclist/triathlete aged between 18 and 40 and are interested in participating in this study or would like some additional information please contact me at b.l.taylor@leedsmet.ac.uk

Caffeine and carbohydrate? That's a cake stop you're describing there. Put me down for a large cappucino with an extra shot and a slab of carrot cake. I'll be needing it by the time I've ridden to Leeds.0

We use a full SRM cycle ergometer and use an online breath-by-breath gas analyser so we can specify accurate power outputs at a % of VO2max. Whilst we won't write a training program for you, we would be more than happy to help identify the correct workloads.0 -

Out of interest how does the SRM ergo compare to the Lode ergo?"A cyclist has nothing to lose but his chain"
