Changes in cortisol concentration in response to exercise at 3 different intensities were quantified. Ten apparently healthy, recreationally active males participated. On 4 separate occasions, subjects were assigned a random order of 1-hour cycle ergometer bouts of exercise at 44.5 ± 5.5%, 62.3 ± 3.8%, and 76.0 ± 6.0% (mean ± SD) of Vo2peak and a resting control session. Saliva samples were collected before exercise at 10, 20, 40, and 59 minutes of exercise and at 20 minutes of recovery… 

Figures and Tables from this paper

Exercise and circulating Cortisol levels: The intensity threshold effect
TLDR
The cortisol findings support the view that moderate to high intensity exercise provokes increases in circulating cortisol levels, but, once corrections for plasma volume reduction occurred and circadian factors were examined, low intensity exercise actually resulted in a reduction in circulate cortisol levels.
Salivary hormone response to maximal exercise at two time points during the day.
TLDR
The data suggest that non weight trained individuals do not display a time of day effect for maximum squat or 5 m sprint performance, or the subsequent salivary hormonal response.
Effect of Exercise with Moderate Intensity in the Morning on Some Factors of Immune Systems in Adults
TLDR
Regular moderate exercise in the morning seems to enhance some factors of mucosal immune function in adults, which, in turn may contribute a decrease risk of infection.
The effect of anaerobic exercise on salivary cortisol, testosterone and immunoglobulin (A) in boys aged 15–16 years
TLDR
The increases in SalT and SalC reported in this study confirm that repeated bouts of short-term, high-intensity exercise produces significant physiological hormonal responses in adolescent boys, but does not affect mucosal immune function.
Effect of consecutive aerobic and resistance exercise on cortisol, immunoglobulin A, and creatine kinase responses in male students
TLDR
This type of consecutive exercise didn't increase susceptibility to upper respiratory tract infection and muscle damage, therefore, it can be useful for the preparation phase of training for athletes.
Salivary Cortisol Responses and Perceived Exertion during High Intensity and Low Intensity Bouts of Resistance Exercise.
TLDR
It was concluded that the session RPE method is a valid and reliable method of quantifying resistance exercise and that salivary cortisol responds promptly to the exercise load.
Concentrations of salivary testosterone, cortisol, and immunoglobulin A after supra-maximal exercise in female adolescents
TLDR
Female adolescents recruited for this study showed no changes in salivary testosterone, cortisol or immunoglobulin A following repeated bouts of supra-maximal cycling (P > 0.05), which provides further guidance with regard to physical activities and sports prescription for female adolescents.
The effects of four weeks aerobic training on saliva cortisol and testosterone in young healthy persons
TLDR
The data support the importance of salivary stress hormones as potential biological markers especially for older ages, however, more research is required to validate these biological markers which determine the host response to physical activity.
Effects of exercise on cravings to smoke: The role of exercise intensity and cortisol
TLDR
Vigorous exercise has a similar effect to moderate exercise in terms of the magnitude of craving reduction, however, performing bouts of moderate-intensity exercise may be a better recommendation for reducing cravings.
Bouts of exercise elicit discordant testosterone: cortisol ratios in runners and non-runners.
TLDR
A biphasic time-profile in the testosterone:cortisol ratio can be seen in short-bout, high intensity exercise (treadmill running) during the morning in men trained for this specific physical activity.

The effect of exercise on serum and salivary cortisol in male children.
TLDR
30 min of submaximal exercise at 70% of VO2max significantly increased serum cortisol level; and salivary and serum cortisol are correlated during and after exercise.
The effects of plasma cortisol elevation on total and differential leukocyte counts in response to heavy-resistance exercise
TLDR
The data indicate that acute increases in total leukocytes along with no changes in differential leukocyte counts can occur in response to heavy-resistance exercise that does not significantly elevate plasma cortisol concentrations.
Effect of mild psychological stress on physiological responses to exercise in men.
TLDR
A mild psychological stress, causing the mood worsening before standard exercise test, does not evoke pronounced alterations in cardio-respiratory responses to exercise in healthy men, but it does affect the magnitude of exercise-induced changes in both plasma free and total noradrenaline concentrations.
Effect of low blood glucose on plasma CRF, ACTH, and cortisol during prolonged physical exercise.
TLDR
The results demonstrate that decreases in blood glucose concentration trigger the pituitary-adrenocortical axis to enhance secretion of ACTH and cortisol during low-intensity prolonged exercise in humans.
Influence of aerobic versus anaerobic exercise on the relationship between reproductive hormones in men.
TLDR
The effects of equal anaerobic and aerobic total work outputs on the relationship between reproductive hormones in men were examined and the area under the hormonal response curves (AUC) was calculated for the 8-h recovery period.
Acute hormonal responses to heavy resistance exercise in younger and older men
TLDR
It is demonstrated that age-related differences occur in the endocrine response to HRE, and the most striking changes appear evident in the FT response toHRE in physically active young and older men.
Trained versus untrained men: different immediate post-exercise responses of pituitary adrenal axis
TLDR
During immediate recovery from the four exercise regimens, the plasma ACTH concentrations of the marathon men were constantly above the values of the sedentary subjects, although plasma cortisol concentration remained similar in both groups, suggesting a change in the pituitary-adrenal relationship at some yet indeterminate level.
Studies on the immediate and delayed leucocytosis elicited by brief (30-min) strenuous exercise
TLDR
Increases in the plasma concentration of cortisol due to exercise correlated positively with the percentage changes in neutrophil numbers at 3 h and 6 h, consistent with the suggestion that the immediate and delayed leucocytosis induced by exercise are mediated respectively by catecholamine and by cortisol.
Regulation of counterregulatory hormone secretion in man during exercise and hypoglycemia.
TLDR
The data suggest that moderate exercise is a stimulus for a sympathoadrenal and GH response, but not a peripheral glucagon response, and during exercise and hypoglycemia, plasma epinephrine and norepinephrine are enhanced, while the glucagon responded is entirely glucose dependent.
Acute hormonal responses to heavy resistance exercise in men and women at different ages.
TLDR
The primary results indicate that the response of GH concentrations to the same relative heavy resistance work load is greatly lowered with increasing age both in men and women, while acute responses in testosterone levels are minor.
