Can a high anti-oxidant diet alleviate inflammation in runners?

Researchers at the University of Newcastle have two opportunities for members of the public to be involved in studies looking into the effects of a high antioxidant diet on inflammation in people who exercise, particularly runners.

Researchers need your help to examine how a high antioxidant diet may improve upper respiratory symptoms in long or middle distance runners.

Runners and athletes who train at very high intensities often experience symptoms associated with airway inflammation such as sore throat, wheezing, and runny nose, all of which may affect their sporting performance. Little is known about the role different dietary strategies play in airway inflammation and also whether men and women respond differently to these strategies.

If we were able to find a dietary strategy that helped to improve these symptoms there is potential for improving the quality of training, reducing time out for illness and consequently improving the performance of athletes. In particular, we may find that men and women require different dietary interventions to achieve the best performance possible.

You must:
+ be 18 years or older
+ female
+ have trained regularly (at least 5 times per week~>40 km running.wk-1) for at least 1 year
+ not have a health condition that would put you at risk of performing exercise or consuming a high antioxidant diet

Exercise has many benefits but we also know that it can cause some degree of inflammation in the body. We need your help for research examining how a high antioxidant diet may protect against exercise induced inflammation.

Exercise is a common strategy that individuals adopt when first attempting to lose weight and individuals often try to exercise at high intensities for faster weight loss. It is thought that intense exercise increases inflammation in the body which can contribute to increased risk of diseases such as heart disease and diabetes. Dietary strategies potentially improve exercise induced inflammation so this research will examine the effects of exercise on the body while individuals follow two different diets, with a focus on any differences in results between men and women. This may help us design better combinations of diet and exercise, or provide more accurate advice regarding the particular benefits that combinations of diet and exercise provide.

You must:
+ be 18 to 45yrs
+ have a BMI >25 and <35kg/m2 (link to BMI calculator)
+ not have a health condition that would put you at risk of performing exercise or consuming a high antioxidant diet
