10k Running Study

Participants needed for Running Study

A research project at the University of Roehampton is currently looking to recruit endurance runners for a project, which is investigating the effects of rinsing the mouth with different carbohydrate solutions on 10K running performance. Recent research has reported that rinsing (but not swallowing) a carbohydrate solution activates the same area of the brain that is activated when a carbohydrate solution is actually drunk, and that cycling performance is improved. We are looking to see if running performance could also be improved by using this technique and whether there would be any differences in performance times if different concentrations of carbohydrate solutions are used.

So what will you have to do?

If you agree to take part in this study, you will be required to complete a VO2max test on a treadmill, a familiarisation trial and three 10k races preceded by a 90 min preload at 65 % VO2max, also on a treadmill, in which you rinse your mouth with either a carbohydrate solution (two different solutions) or a placebo solution. You also need to keep a food diary for 24-h before your first visit to the laboratory.

So what are the benefits of taking part in this study?

In return for participating, you will receive feedback on your fitness, VO2max and if desired, nutritional feedback. You will also get insight in how studies are done, and you would get the results of the study when it is finished.

So who are we looking for?

I am looking for male runners aged 18-50 years, with at least 2 years running experience. You will also need to currently be undertaking 2 days of endurance training a week.

  • What do you class as 2 days of endurance training p/week ?

    Also, how many times would one need to visit your lab?

    I'm 26 and knock out around a 38min 10k


  • Just to make sure that the people joining the study are able to finish the study, as you will be running for about 2 1/2  hour without stopping. Please send me an email if interested, and I can give you more information about the study. 

  • Bugger, I'm 51. But Rohampton isn't too far from me so if you extend the age limit do feel free to let me know.

    Bet quite a few of this lot could spot a placebo at 100 yards!


  • Quick question - when will this be starting? Currently injured at the minute but planning on lowering my 10k pb over the summer and Roehampton isnt to far from me!

  • I've taken part in three lots of university sports studies so far and never had any feedback or data of any sort. Never again!

  • I need to be done with my testing at the end of July, so if you recover from your injury, it should be fine. Please send me an email if you are interested and want some more information. 

  • Probably a bit early for me, don't think I will be racing again until late-July / Mid-August, so the thought of 3 x 10k races before EO-July doesnt sound feasible image Thanks for getting back on that, good luck with your research
