Northern Board Beet Breathlessness Trial

Hypothesis: Beetroot juice increases the exercise tolerance of patients with chronic lung disease.

Using the already established pulmonary rehabilitation model, we aim to split the group of 8 into 2 groups, each group taking 500ml of beetroot juice 24 hours before there class on alternate (differing) weeks to see if it improves their overall exercise tolerance.

Inclusion Criteria:

• Already planned to attend the pulmonary rehabilitation class

Exclusion Criteria:

• Angina Prescribed regular nitrates, a resting heart rate >100bpm, a resting blood pressure <110 systolic, postural hypotension, prescribed PDE5 inhibitors.
