Previous studies have shown that sodium bicarbonate ingestion prior to exercise may improve performance during repeated (interval) bouts. To examine the practical implications of such findings, seven collegiate swimmers participated in simulated swim competitions of multiple events following sodium bicarbonate (B) ingestion, placebo (P) ingestion and(More)
In contrast to our previous studies on the submersion of scuba divers in a state of neutral buoyancy, neither plasma beta-endorphin-like immunoreactivity (beta-EIR) nor affective feelings were significantly changes in scuba divers by mimicking diving pressures of 2 feet (0.6 m) and 50 feet (15.2 m) for 20 min in a hyperbaric chamber. It is concluded that(More)
The submersion of eight male scuba divers in a state of neutral buoyancy for 20 min resulted in a significant increase (mean, 20%) in plasma beta-endorphin immunoreactivity (beta-EIR), and all subjects reported post-submersion feelings of well-being, relaxation or euphoria. The increase in beta-EIR was negatively correlated with age (r = -0.727) and diving(More)
