2017/4/13
Purpose: The goal of this study was to explore the effect of lifelong aerobic exercise (i.e., chronic training) on skeletal muscle substrate stores (intramyocellular triglyceride [IMTG] and glycogen),...
Effects of Oral Sodium Supplementation on Indices of Thermoregulation in Trained, Endurance Athletes
Salt sweat hydration heat stress heart rate electrolyte
2015/5/26
Guidelines recommend the consumption of sodium during exercise to replace losses in sweat; however, the effects of sodium on thermoregulation are less clear. To determine the effects of high-dose sodi...
