This Supplement Enhances Muscle Performance
Scientists in Brazil and Canada have examined the effects of two different doses of caffeine on muscle strength and calcium levels in blood. Caffeine may enhance muscular strength by altering the capacity of calcium release. This study, published in Nutrients, contributes to a better understanding of the effects of acute caffeine supplementation on muscular strength and calcium release rates, which was previously unclear. 21 male recreationally-trained (that is, neither untrained nor well-trained) volunteers participated in this study. All participants had been actively engaged in at least four hours per week of strength training for the 12 months prior to the beginning of the study. They didn’t have any pathology or…

This Supplement Protects Heart from Intense Exercise Risks
Scientists have examined the effects of Alpha Glycerylphosphorylcholine (Alpha GPC) on blood dynamics and heart rate variability. This was done in women who were overweight or obese, following a sprint interval exercise. While its overall health benefits are well known, intense exercise can have unwanted side effects on vulnerable people. In particular, without preventive measures, overweight people can experience high blood pressure responses and acute cardiac events after intense exercise. Therefore, it is important to find way to reduce the cardiac risks of exercise. Alpha GPC, a food supplement for healthy individuals, is thought to have favorable effects on the central nervous system and possible protective influences on cardiovascular functions.…
