Beetroot Juice as a Potential Ergogenic Aid During Exercise in Hypoxia

The study will aim to describe and evaluate the effect of beetroot juice supplementation upon whole body running exercise at altitude. It is hypothesised that beetroot supplementation will decrease time to complete a 10 km time trial.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
EXPERIMENTAL: Beetroot shot then placebo shot; Intervention: Participants will first consume a Beetroot shot: 1x70ml concentrated NO-3 shot of rich Beetroot juice (~7mmol nitrate) (Beet It, James White Drinks Ltd, Ipswich, UK). Following a four day wash out, participants will then consume a Nitrate-depleted beetroot shot: 1x70ml nitrate-depleted beetroot Placebo shot (~0.003mmol of nitrate)(Beet It, James White Drinks Ltd, Ipswich, UK)	Dietary supplement: Beetroot shot then placebo shot; Beetroot shot, four day wash out, then placebo shot
PLACEBO_COMPARATOR: Placebo shot then beetroot shot; Intervention: Participants will first consume a Nitrate-depleted beetroot shot: 1x70ml nitrate-depleted beetroot Placebo shot (~0.003mmol of nitrate)(Beet It, James White Drinks Ltd, Ipswich, UK). Following a four day wash out, participants will then consume a Beetroot shot: 1x70ml concentrated NO-3 shot of rich Beetroot juice (~7mmol nitrate) (Beet It, James White Drinks Ltd, Ipswich, UK).	Dietary supplement: Placebo shot then beetroot shot; Placebo shot, four day wash out, then beetroot shot
