This interconnected feedback loop of regulation is referred to as the hypothalamic-pituitary-adrenocortical HPA axis and is illustrated in Figure 1. Additionally, cytokine agents such as interleukin-6 IL-6 have been linked to stimulating HPA responses and promoting increases in circulating cortisol Ostrowski et al. Brief Overview of the Cortisol Response to Exercise. The intent of this section is to provide only a brief overview and summary of the cortisol responses to exercise.
For a more in-depth discussion of this topic the reader is directed to references M. Kjaer and R. McMurray and A. Hackney This threshold intensity does however increase slightly as an individual becomes more exercise trained.

Thus at the same absolute exercise intensity, the cortisol response may be lower following an exercise training program. During supra-maximal exercise, the cortisol response can be extremely pronounced, but this increase may not be displayed until recovery from the activity, due to the short duration of such activity Viru, ; Kjaer, ; Hackney, During sub-maximal exercise, cortisol responses are more variable and are influenced by several external factors.
If the sub-maximal exercise is below the critical threshold intensity then cortisol levels may not increase above resting levels, or they may actually become reduced Hill et al. If such low intensity exercise is prolonged enough in duration, levels may gradually increase over time above resting values.
If the sub-maximal exercise is above the critical threshold intensity, then cortisol levels will initially increase and subsequently plateau, provided the exercise is steady-state Viru, ; McMurray, Hackney, ; Viru et al.
The level of the plateau is proportional to the intensity of the exercise conducted, but if the exercise is prolonged enough in duration, hormone levels will gradually begin to increase again over time Viru, ; Viru et Hypothalamus Anterior Pituitary Adrenal Cortex Antony C.
Evans Stress e. Consumption of a low carbohydrate diet for several days can augment the subsequent cortisol response to sub-maximal exercise Galbo, ; Kjaer, Furthermore, ambient environmental temperatures can dramatically influence the cortisol response to sub-maximal exercise.
Extremely hot or cold temperatures can augment the cortisol response to an exercise session Galbo, ; Numesti svorio ashford kent, Hackney, Finally the more exercise trained a person, typically the more blunted the cortisol response to nearly any level of sub-maximal exercise condition Viru, ; Viru, ; Viru et al.

At Rest and during Recovery from Exercise. The background information above on the physiologic actions of cortisol illustrate when released in normal amounts, cortisol like other glucocorticoid agents has widespread actions which help restore homeostasis of the body after exposure to a stress such as exercise. Most certainly the metabolic influence of cortisol does involve activation of catabolic processes and anti-anabolic actions at the cellular level in many tissues of the body Bender, However, these actions are critical to the promotion of protein synthesis which is necessary for the adaptation process in response to a stressful situation Dohm, ; Bender, ; Viru et al.
For example, these actions lead to a significant increase in the free amino acid pool. Damaged or disrupted protein structures are degraded and their constituent amino acids are placed in the fluids of cells and tissues Dohm, ; Booth, Thomasson, ; Brooks et al.
These free amino acids are available as recyclable components or building blocks for the synthesis of new proteins, and an expansion of the pool advances this action. Cellular control of protein synthesis essentially occurs at three levels; pre-translation transcriptiontranslation, and post-translation Booth, Thomasson, ; Tortora, Derrickson, The impact of cortisol upon the free amino acid pool is influential at the translation level, which consists of constructing and adjusting the number of protein molecules necessary to the need or demand of cells Booth, Thomasson, ; Bender, Such actions and influences in combination with anabolic endocrine agents can result in enhanced enzymatic 37 and structural proteins in a variety of tissues; i.
The ability of the human body to undergo an adaptation in shape, size or characteristic when subjected to a stress exceeding a particular prior normal level is referred to as the property of plasticity Brooks et al.
Table summarizes and illustrates aspects of the body s ability to perform a remarkable degree of plasticity in response to exercise training this is especially true within skeletal muscle tissue i.
Figure 2 is a schematic illustration representative of the proposed model for factors that influence the myo-plasticity in human skeletal muscle Brooks et al. The hormonal inter-play of such endocrine factors as glucocorticoids cortisol and anabolic hormones insulin, testosterone, and insulin-like growth factor 1 are critical and necessary to bring about and maximize the myo-plasticity response in skeletal muscle in response to exercise training Sheffield-Moore, Urban, During Exercise.
The increases in cortisol seen during exercise are critical to the control and regulation of energy metabolism and thus exercise performance capacity Viru, ; Viru, ; Viru et al.
This point is well documented in human studies, but is eloquently illustrated in animal-based studies where cortisol responses can be either mitigated through removal of the adrenal gland, or modulated through pharmaceutical implants it is important to note the principal and most potent glucocorticoid in rodents is corticosterone. For Table. Examples of select, critical physiological changes occurring with exercise training see Brooks et al.
Evans Figure 2. Schematic representation of the plasticity model of adaptation and the critical components which influence skeletal muscle myo-plasticity modified from Brooks et al. Sellers et al. During exercise, such adrenalectomized rats also displayed suppressed muscle and hepatic alanine-aminotransferase activity a key enzyme in protein metabolism function as well as reduced urea production and elimination Viru, Eller, ; Viru et al.
Furthermore, due to an overall decrease in hepatic gluconeogenic capacity, glucose output is reduced in such animals, thus leading to hypoglycemia during exercise, which is a potent cause of fatigue Gorski et al.
Duclos et al. An important role of glucocorticoids is the induction of the enzymes associated with catecholamine production, principally the synthesis of phenyl-ethanolamine-n-methyl transferase. This enzyme catalyzes the methylation of norepinephrine to epinephrine Pohorecky, Wurtman, Animal research supports that the absence of a glucocorticoid response during exercise results in suppressed catecholamine levels throughout exercise kaip prarasti pilvo ir klubų riebalus causes a compromised regulation of several critical physiologic systems Matlina et al.
There also appears to be a reciprocal effect between the catecholamine and cortisol interactions. Evidence demonstrates that by blocking the actions of the catecholamines adrenergic receptor blockagethere is suppression of cortisol release Pohorecky, Wurtman, Viru and associates showed such blockage in humans suppresses the cortisol response to strenuous exercise, significantly compromising exercise performance Viru et al.
Besides direct actions, glucocorticoids can exert permissive and supportive effects on some metabolic events occurring during exercise. For example, glucocorticoids appear to influence the calcium fluxes in cells and can have inhibitory action on the synthesis of camp-phosphodiesterase Viru A. These actions in-turn promote a greater metabolic action for epinephrine, leading to and accentuating the fatty acid release from adipocytes and accelerating lipolysis during exercise Malig et al.
Even though the catabolic actions of cortisol lead to an expanded free amino acid pool, evidence suggest that enhanced contractile activity such as in exercise numesti svorio ashford kent actually defend muscle tissue from an exaggerated level of numesti svorio ashford kent and spare some skeletal proteins from degradation Hickson, Davis, ; Seene, Viru, ; Dohm, ; Varrick et al.
Furthermore, R. Hickson et al. This in turn allows testosterone to facilitate receptor action and thus reduces glucocorticoid catabolic action. It is important numesti svorio ashford kent note that at the receptor level, a competition can exist between structurally alike hormones such as testosterone and cortisol for binding sites on receptors. The competition between cortisol and testosterone for glucocorticoid-binding sites salono kūnas plonas albertas a determinant of the anti-catabolic action of testosterone and the anti-anabolic action of cortisol Mayer, Rosen, Excessive Responses and Exercise.
Most certainly cortisol and the other glucocorticoids have deleterious effects on the body when excessive levels are reached Hickson, Davis, ; Tortora, Derrickson, Some of the greatest elevations of cortisol are seen in the medical condition known as Cushing s Syndrome Daly, Hackney, ; Tortora, Derrickson, Patients with this condition experience many of the health problems negative physiological changes mentioned earlier which are promoted by excessive levels of cortisol.

Some individuals have speculated that exercise results in a hypercortisolemic state, either as a transient occurrence due to acute exercise or chronically due to overtraining, and this state can induce some of these deleterious physiological effects in athletes Viru A. However, M. Furthermore, W. Daly and A. Hackney compared the levels of cortisol in response to intensive prolonged exercise to those found in Cushing s Syndrome patients.
The levels in the Cushing s patients far exceeded any of those found in the individuals who exercised. Even patients with anxiety disorders or excessive psychological stress are found to 39 have cortisol levels that typically exceed those found in response to exercise Boa et al. Additionally, A. Hackney and A. Viru as well as W. Kern et al. The glucocorticoids are in fact vital hormones in the normal physiological functioning of humans and are necessary in dealing with different stress challenges to the body.

With respect to exercise, they play an important regulatory role in metabolic responses. Additionally, the regulation of protein turnover during the recovery from exercise, which is instrumental to the myo-plasticity response of skeletal muscle in training, is dependent upon appropriate glucocorticoid actions.
In other words, cortisol and the other glucocorticoids are not the bad guys of exercise endocrinology as some have made them out to be. Researchers, athletes and sports coaches need to be aware and conscious of the critical nature of glucocorticoids to normal health and development, especially relative to exercise training adaptations.
