Previous research in sub-elite athletes suggest regular training and an antioxidant-rich diet enhances antioxidant defences, but not performance.<\/p>\n<p>PURPOSE: <\/p>\n<p>To investigate whether habitual diet and\/or exercise (training status or performance) affect antioxidant status in elite athletes.<\/p>\n<p>METHODS: <\/p>\n<p>Antioxidant blood biomarkers were assessed before and after a 30-min ergometer time trial in 28 males and 34 female rowers. The antioxidant blood biomarkers included ascorbic acid, uric acid, total antioxidant capacity (TAC), erythrocyte- superoxide dismutase (SOD), glutathione peroxidise (GPx) and catalase (CAT). Rowers completed a 7-d food diary and an antioxidant intake questionnaire. Effects of diet, training and performance on resting biomarkers were assessed with Pearson&rsquo;s correlations and their effect on exercise-induced changes in blood biomarkers were assessed by a method of standardisation.<\/p>\n<p>RESULTS: <\/p>\n<p>With the exception of GPx, there were small to moderate increases with exercise for all markers. Blood resting TAC had a small correlation with total antioxidant intake (Correlation 0.29; 90% confidence limits, \u00b10.27) and the exercise-induced change in TAC had a trivial\/small association with dietary antioxidant intake from -vitamin C (Standardised effect 0.19; \u00b10.22), -vegetables (0.20; \u00b10.23) and vitamin A (0.25; \u00b10.27). Most other dietary intakes had trivial associations with antioxidant biomarkers. Years of training had a small inverse correlation with TAC (-0.32; \u00b10.19) and a small association with the exercise-induced change in TAC (0.27; \u00b10.24).<\/p>\n<p>CONCLUSION: <\/p>\n<p>Training status correlates more strongly with antioxidant status than diet.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-35135","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"The University of Auckland, Discipline of Nutrition, Faculty of Medical & Health Sciences, Auckland.","annee":"2013","mois":"2","numero":"","page":"","auteurs":[{"ID":4874,"post_author":"0","post_date":"2018-12-03 17:21:50","post_date_gmt":"2018-12-03 16:21:50","post_content":"","post_title":"Andrea J Braakhuis","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"andrea-j-braakhuis","to_ping":"","pinged":"","post_modified":"2018-12-03 17:21:50","post_modified_gmt":"2018-12-03 16:21:50","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/andrea-j-braakhuis\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":35132,"post_author":"0","post_date":"2018-12-04 00:39:36","post_date_gmt":"2018-12-03 23:39:36","post_content":"","post_title":"Hopkins","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"hopkins","to_ping":"","pinged":"","post_modified":"2018-12-04 00:39:36","post_modified_gmt":"2018-12-03 23:39:36","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/hopkins\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":35133,"post_author":"0","post_date":"2018-12-04 00:39:36","post_date_gmt":"2018-12-03 23:39:36","post_content":"","post_title":"Lowe","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"lowe","to_ping":"","pinged":"","post_modified":"2018-12-04 00:39:36","post_modified_gmt":"2018-12-03 23:39:36","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/lowe\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":35134,"post_author":"0","post_date":"2018-12-04 00:39:37","post_date_gmt":"2018-12-03 23:39:37","post_content":"","post_title":"INT J SPORTS PHYSIOL PERFORM","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"int-j-sports-physiol-perform","to_ping":"","pinged":"","post_modified":"2018-12-04 00:39:37","post_modified_gmt":"2018-12-03 23:39:37","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/int-j-sports-physiol-perform\/","menu_order":0,"post_type":"source","post_mime_type":"","comment_count":"0","filter":"raw"}]},"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v23.6 (Yoast SEO v23.6) -
