U.S., Aug. 19 -- ClinicalTrials.gov registry received information related to the study (NCT07771556) titled '7-Day Caffeine and Upper-Body Power in Active Women' on Aug. 10.
Brief Summary: This study investigated the effects of a 7-day caffeine supplementation on heart rate variability, cognitive performance, and upper-body anaerobic power in active women. Thirty healthy active women aged 25-30 years participated in this double-blind, placebo-controlled trial. Participants were randomly assigned to receive either 5 mg/kg of caffeine or a placebo daily for 7 days. Heart rate variability, cognitive function (measured by the Stroop test), and upper-body anaerobic power (measured by a 20-second Wingate test) were assessed at baseline, 90 minut...
