Effects of glucose ingestion on autonomic and cardiovascular measures during rest and mental challenge

This study examined the effects of controlled glucose intake on cardiovascular measures at rest and in responses to mental challenge in a laboratory setting.Method: Using a double blind within-subjects design, participants were monitored at baseline, following ingestion of a glucose or taste-control solution, during structured speech (SS), anger recall (AR) and recovery (N=24, 288 repeated measures; age=21±2years). Pre-ejection period (PEP), heart rate (HR), stroke index (SI), cardiac index (CI), blood pressure and total peripheral resistance (TPR) were measured throughout the protocol.Results: Glucose resulted in sustained decreased PEP levels compared to control condition (Δ=11.98±9.52 vs. 3.27±7.65m·s, P
