Effect of Acute Grape Seed Extract Supplementation on the Heart Rate Recovery in Young Individuals

Not Applicable
Completed
Conditions
Healthy Young Men
Registration Number
NCT07137988
Lead Sponsor
California Baptist University
Brief Summary

This study hypothesized that sustained sympathoexcitation via MMA slows down PHRR and that GSE supplementation is effective at improving PHRR in young individuals. 12 Participants were randomly assigned, via a double-blind, cross-over design, to either receive GSE (300mg, 2 capsules) or PL (300mg, 2 capsules), with a washout period of at least 72 hrs. between trials. A submaximal exercise test was performed using a cycle ergometer combined with isometric handgrip exercise using a handgrip dynamometer, and blood flow occlusion by placing a cuff over the brachial artery of the dominant arm. Post heart rate recovery (PHRR) was measured at 5 sec. intervals throughout the experiment. The PHRR was evaluated between GSE and PL at every min. for 300 sec.
