Cardiovascular Function During Supine Rest in Endurance-Trained Males with New Zealand Blackcurrant: A Dose-Response Study

Synopsis: 

• Dose-response study investigating cardiovascular responses in cyclists at rest, with 300mg, 600mg, 900mg NZB extract
• Results showed NZB extract had a moderate to large effect on CV responses
• Responses varied between doses, highest at 900mg
• Extract reduced total peripheral resistance by 20.2% (900mg)
• Increased cardiac output 27.5% (900mg)
• Increased stroke volume 17.7% (900mg)
• Effect on blood volume pumped may enhance post-exercise recovery in athletes
• May be beneficial for clinical populations affected by reduced circulation
