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. <b>Description: </b>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.

本元数据记录（metadata record）及其附带文件阐明了本研究所收集的各类数据范畴，并制定了该数据当前及未来的治理政策。<b>数据集说明：</b>地面臭氧（ground-level ozone）暴露会损害肺功能（lung function）并引发全身性炎症（systemic inflammation）。尽管户外锻炼因其对身心健康的益处而被广泛倡导，但在空气污染（air pollution）环境中进行锻炼会引发一系列病理生理反应（pathophysiological responses），且已被证实与认知能力下降（cognitive decline）相关。黑加仑（blackcurrants）富含多酚类物质（polyphenols），可减轻臭氧引发的肺部炎症（lung inflammation）损伤，并对情绪与认知产生积极影响。由于通气量（ventilation）增加、呼吸速度加快，污染物会更深入呼吸道（respiratory tract），因此运动中的运动员对空气污染的影响更为敏感。本研究旨在探究7天补充服用黑加仑粉是否能够缓解呼吸道症状（respiratory symptoms）与肺部炎症，并改善运动表现（exercise performance）。此外，本研究还将考察补充剂对认知功能及血清脑源性神经营养因子（Brain-Derived Neurotrophic Factor，BDNF）的影响。
