Xtreme Everest release findings of Bedford School study
Xtreme Everest have recently published a new paper which looks at the effects of dietary nitrate supplementation on symptoms related to acute mountain sickness.
Entitled Effects of dietary nitrate supplementation on symptoms of acute mountain sickness and basic physiological responses in a group of male adolescents during ascent to Mount Everest Base Camp the paper looks at the study of forty-one healthy male students aged between 14 and 18 who were recruited from Bedford School in Bedfordshire, England.
The students trekked to Everest Base Camp over 11 days with a team from Xtreme Everest. Following an overnight fast, each morning the participant completed a Lake Louise Acute Mountain Sickness (AMS) questionnaire before undertaking a series of physiological testing:
- resting blood pressure
- resting and exercising heart rate
- respiratory rate
- peripheral oxygen saturation
Participants who were put into the intervention arm of the study also consumed 140ml of concentrate beetroot juice daily. whilst those on the control arm consumed 140ml of concentrated blackcurrant cordial. Drinks were taken for the first seven days at high altitude in two equal doses - at breakfast and with an evening meal.
The principle finding of the study showed that nitrate supplementation does not increase or reduce symptoms of AMS, or alter key physiological variables, in a group of adolescent males during ascent to high altitude.

In addition to the above paper, the researchers also completed a case report as part of the project entitled Isolated Generalized Tonic-Clonic Seizure at High Altitude in a Young Male Trekker with a Positive Family History of Seizure. To read this please visit the NCBI website
