 New View of Statistics: Models - Details
This pattern of epinephrine responses in trained vs untrained individuals was also found in studies where the adrenal medulla was specifically stimulated with various non-exercise stimuli (Yamaguchi 1992, Cheung 1990).
As an example, Stallknecht et al (1990) found that the epinephrine response to hypoglycemia in the swim-training rats (with adrenal medulla hypertrophy) was markedly diminished.
The development of a "sports adrenal medulla" might be caused by the repeated stimulation of epinephrine secretion occurring with training.

 How to Cope with Adrenal Fatigue
The adrenal glands, situated above the kidneys and composed of the adrenal medulla and adrenal cortex, play an integral role in the body's stress response, especially its "fight-or-flight" response.
The adrenal medulla secretes epinephrine (adrenaline) and norepinephrine (non-adrenalin), affecting heart rate, respiration, and digestion.
Please consult your health care provider if you have a serious condition.

 History of the Adrenal Medulla
Alongside these studies of the clinical picture of adrenal medullary pathology, physiologists were carrying out the classic studies on the function of the adrenal medulla.
A recent technique that has helped make the adrenal medulla even more valuable for studying peptides, receptors, and many other aspects of neurobiology was the development of methods for isolating and culturing adrenal chromaffin cells.
It is of interest to note that the direct relationship between the adrenals and gonads, as envisioned by these early workers, had no basis in fact, although today we do recognize important interactions between the gonads and the adrenal cortex.

Large pheochromocytomas are multilobular and variegated, and they may exert pressure on and invade adjacent tissues, particularly the vena cava and aorta.
Functional pheochromocytomas are reported infrequently in animals; however, several dogs and horses with pheochromocytomas have had tachycardia, edema, and cardiac hypertrophy attributed to excess catecholamine secretion.

 Adrenal Medullary Hormones
Complex physiologic responses result from adrenal medullary stimulation because there are multiple receptor types which are differentially expressed in different tissues and cells.
In general, circulating epinephrine and norepinephrine released from the adrenal medulla have the same effects on target organs as direct stimulation by sympathetic nerves, although their effect is longer lasting.
Many types of "stresses" stimulate such secretion, including exercise, hypoglycemia and trauma.

 Extreme sport -- Facts, Info, and Encyclopedia article
Some participants termed 'adrenaline junkies' develop an obsession with their sport and even claim to be "addicted to (A catecholamine secreted by the adrenal medulla in response to stress (trade name Adrenalin); stimulates autonomic nerve action) adrenaline".
Extreme sports are most often pursued by young adults who wish to push their own limits of fear and physical ability, and in doing so, also help to push the limits of their sport as a whole.
Levels of danger vary widely, but there is always an element — an "extreme" factor — that causes an adrenaline rush which keeps participants loyal to their sport.
