Bungee jumping: Metabolism, cardiovascular changes, and electrolytes in severe mental excitement

摘要

Of 78 officer trainees, blood samples were taken from the fingertip before and after bungee jumping. Using a Phox M device, pCO(2), pO(2), and ionized Mg were determined. Systolic blood pressure (RRsys) was measured by a Beurer device. Also, subjective excitement score before the jump (only 40 participants) was determined. It turned out that before the jump, only the excitement score correlated with blood pressure (RRsys); but after the jump, Mg values became proportional to RRsys. Excitement scores before the jump as well as RRsys correlated with Mg values after the jump. Mental load obviously could quickly induce considerable metabolic and electrolyte changes. Moreover, a smaller mental load during sympatho-adrenal anticipation correlated linearly with cardiovascular and metabolic data of the more severe load afterwards. which paves the way for prognostic use.
