title: [Radiotelemetric study of heart rate and electroencephalogram during parachute jumping (author's transl)].
abstract: Twelve subjects, experienced parachutists, have been recorded by telemetry before, during and after free-fall parachute jumps. The heart rate showed a statistically significant tachycardia during the different events of the jump (exit, free-fall, opening, open parachute and landing) compared to the baseline before boarding the aircraft. This tachycardia indicates a stress reaction confirmed by a significant increase of adrenalin and noradrenalin in urine. The electroencephalographic invesitgation does not show any adnormalities. Alpha rhythms have been recorded from alpha reactive subjects during free-fall stabilization.
