“…The BMI can be improved by counselling and promoting lifestyle changes in mass population. Dietary intake should be monitored and healthy nutrition should be reinvigorated [30]. Persistent and high cortisol secretions lead to metabolic derangement that predisposes to obesity and worsen the depression in patients.…”

“…Regardless, no consensus exists on the course of response to an exertion stressor. According to a common assumption, from the onset of a high-intensity stress, the cortisol concentration in the blood begins to rise sharply [22], although many studies [4,6,23,24] show the opposite. The cortisol response to physical exertion undoubtedly undergoes influences from many factors related to both the functional and structural properties of the individual, such as age [25], physical capacity [26], and body build and composition (particularly differences in body fat content, which reportedly determine, to some extent, cortisol levels and their changes under stress [6]).…”

Background: Inconsistencies in measurements of cortisol response to stress have caused disagreements in the direction of the change in cortisol concentrations immediately after the onset of stress. Researchers typically observe increased cortisol levels in response to a stressor, perceiving occasional decreases as a sign of possible disorders. Reports indicate the relative ease of standardizing a physical stressor compared with a mental stressor, and cross-stressor adaptation is observable only in elite athletes. Methods: We investigated the cortisol response to top-intensity physical exertion by analyzing the course of the cortisol response, the changes in this response resulting from adaptation to intense exercise, and the possible convergence between the cortisol changes and body fat content. We examined 16 male athletes, members of the Polish National Rowing Team, competing in the World Rowing Championships, in top form, of an average training experience of seven years. The measurements were performed before and after the training camp preparatory to the Championships. We performed the measurements before and after the training camp preparatory to the Championships. Results: Before the camp, the athletes consistently reacted to the exertion test with a decrease in cortisol concentration and elevated cortisol levels after rest compared with baseline. After the camp, the post-exertion cortisol decrease as well as the post-rest cortisol elevation was much smaller and less consistent. Conclusions: The transient decrease in cortisol concentration at the onset of stress thus represents a physiological reaction, and the stress response counteracts the resulting cortisol deficiency to support cortisol availability during stress. Adaptation to stress enhanced this counteracting effect by (1) increasing the baseline cortisol concentration and (2) speeding up the response to its decline. This enhanced effect was boosted by adipose tissue.
