Urinary excretion of free noradrenaline and adrenaline in trained and untrained men.

Urinary excretion of free noradrenaline and adrenaline in trained and untrained men.

Measurements of free noradrenaline and adrenaline were made in the urine of 28 men sampled after rest and exercise prior to, and following six and twelve weeks of an excercise programme. The training consisted of thirty minutes of running and walking four times per week at an intensity estimated at 75% of the age-predicted maximum heart rate. A fifteen minute standardized cycle ergometer work t...

Urinary excretion of adrenaline and noradrenaline during prolonged immobilization.

Ss who successfully completed 1 wk. of immobilization showed no significant changes in subjective stress and mood or in the urinary excretion of adrenaline and noradrenaline (catecholamines) relative to recumbent controls. On the other hand, the catecholamine excretion of the immobilization quitters was related to their endurance. The early quitters showed no significant changes, whereas the la...

Nocturnal asthma and urinary adrenaline and noradrenaline excretion.

Urinary excretion of adrenaline and noradrenaline during prolonged perceptual deprivation.

Ss who successfully completed a week of perceptual isolation showed no significant changes in urinary excretion of adrenaline and noradrenaline relative to a group of control Ss. They also showed no changes on a behavioral measure of subjective stress and mood. Isolation "quitters," i.e., those who failed to complete the prescribed period, also showed no change in noradrenaline. Their urinary e...

Free adrenaline and noradrenaline excretion related to occupational stress.

Urinary levels of free adrenaline and noradrenaline were measured in two groups of healthy male industrial workers exposed to alternate four-day periods of working conditions with and without time stress, to test the hypothesis that the sympathetic nervous system is overactivated by occupational stress. Thirty confectionary workers alternated piece-work (payment by results) and work with a fixe...
