HVN1902 Metadata Record - Effects of a blackcurrant powder blend on repeated high-intensity cycling performance, attention and lung function under pollution exposure in highly trained male cyclists

This metadata record and it's attached files make statements about the kinds of data collected as part of this research, and set out policies for governance of that data, now and in the future.

Description: Exposure to ground-level ozone impairs lung function and induces systemic inflammation. Outdoor exercise is advocated for both its physical and mental health benefits, yet exercising in air pollution induces an array of pathophysiological responses and shown to be related to cognitive decline. Blackcurrants contain high levels of polyphenols that may mitigate the damaging effects of ozone on lung inflammation, and positively influence mood and cognition. The exercising athlete is more susceptible to the influence of air pollution due to increased ventilation, and breathing velocity transporting pollutants further into the respiratory tract. The objective of this study is to see if 7 day supplementation of blackcurrant powder reduces respiratory symptoms and lung inflammation, and assists exercise performance. In addition to this, the effects of supplementation on cognition and serum BDNF will be examined.
