    Values are means

Using a combination of exercise and heat stress, the present study examined whether prior disruption of bloodbrain barrier (BBB) integrity in normoxia would alter individual susceptibility to neurovascular headache initiated during subsequent exposure to inspiratory hypoxia. Eleven males aged 24
