About the thesis
This thesis includes two studies investigating middle-aged males with and without elevated blood pressure.

One study investigates the effect of 8 weeks of high-intensity interval spinning training on vascular function and the sympathetic nerve activity to the muscles. This study also investigated the effect of the pannexin-1 channel, which modulates the sympathetic nerve activity to the muscles.

The other study investigated the effect of the pharmaceutical drug colchicine, immediately after ingestion and after 3 weeks of twice daily treatment, on vascular response to ß-adrenergic activation. The thesis concludes that; changes in sympathetic nerve activity to the muscles cannot explain the reduction in blood pressure seen with training in subjects with elevated blood pressure. Furthermore, the pannexin-1 channel cannot explain the reductions in blood pressure mentioned above. Lastly, colchicine causes vasodilation caused by ß-adrenergic activation immediately after ingestion.
