Creatine Monohydrate: Daily Blood Pressure Monitoring During the Loading Phase of Supplementation

The aim of this study was to determine if CM supplementation in normotensive college-aged males induces a daily blood pressure increase during the supplementation-loading phase. Participants' blood pressure, shoulder extension active range of motion (AROM), arm girth, arm volume, plasma volume,...

Description
Summary:	The aim of this study was to determine if CM supplementation in normotensive college-aged males induces a daily blood pressure increase during the supplementation-loading phase. Participants' blood pressure, shoulder extension active range of motion (AROM), arm girth, arm volume, plasma volume, blood volume, hematocrit, and hemoglobin were measured daily for five days of supplementation (4x5gxd super(-1)x5d) of either CM (n=12) or placebo (P; n=12). The CM group did not experience significant changes in systolic blood pressure(mmHg) (CM 126.7+ or -1.9 sub(Day 5); P 125.5+ or -2.6 sub(Day 5)) or diastolic blood pressure (mmHg) (CM 83.8+ or -2.2 sub(Day 5); P 82.3+ or -2.1 sub(Day 5)) compared to P. There were significant time x treatment interaction (p=0.001) and treatment effect (p=0.03) supporting a decline in AROM(cm) in the CM group compared to P (CM 38.3+ or -2.2 sub(Day 1), CM 34.0+ or -2.0 sub(Day 5); P 41.0+ or -2.5 sub(Day 1), P 43.2+ or -2.5 sub(Day 5)).
