Abstract:
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 the submersion-induced increase in plasma beta-EIR and accompanying changes in affect reported previously are not due solely to changes in pressure.
