“…Its primary functions are to increase protein breakdown, inhibite glucose uptake and increase lipolysis. The level of serum cortisol is effected by many factor such as intensity, duration and timing of exercise, type of exercise, age, altitude, environmental temperature and psychology (Bernet and Wartofsky, 2000;Deligiannis et al, 1993).…”

Some metabolic and endocrine functions might be influenced by exercise and it leads to changed concentrations of hormone secretions in humans. In order to determine the changes of thyroid hormones (THs) related to shuttle run exercise (SRE), 14 field hockey players and their thyroid stimulating hormones (TSH) free T3 (fT3), free T4 (fT4) were included in this study, and cortisol levels were measured three times; before the exercise, just after the exercise and one hour later after exercise. The results of this study showed that there were no statistically significant differences among three measurements in the serum levels of TSH and thyroid hormones. However, both fT3 and TSH were significantly decreased in one hour later after exercise, whereas no change was observed in fT4. Cortisol concentrations were slightly increased immediately after SRE. In conclusion, serum levels of thyroid stimulating hormone and thyroid hormones were affected by maximal aerobic exercise.

The human body when subjected to heavy loads of physical training suffers numerous modifications to adapt to stress. Various systems are directly and indirectly affected, we can mention the cardio respiratory system as the one that suffers the most modifications when we are facing an intense physical load. Another system that modifies and of which we will explain in this paper is the endocrine system, specifically the thyroid gland who suffers some changes. This paper aims to demonstrate and exemplify the changes in the thyroid gland during physical activity, such as the release of pro-and anti-inflammatory cytokines, and the alteration occurred in the release of thyroid hormones. All these changes suffer direct influence on the athlete's performance being a limiting factor for a good performance. Through this paper, we exemplify the changes in the thyroid gland during exercise in order to seek an intervention for these transformations, aiming ultimately a good performance of the athlete.

To prevent lifestyle related diseases, it is important to modify lifestyle behavior. The control of mental stress level and prevention of mental stress-related diseases have become one of the most important problems in Japan. To check mental stress level objectively during the early stage of stress-related diseases and determine appropriate coping methods, it is necessary to design a useful index for mental stress. Cortisol is a steroid hormone secreted by the adrenal cortex. This is an essential hormone to human survival, and plays a key role in adaptation to stress. In another review, we concluded that cortisol appears to be an adequate index for mental stress.However, lifestyle factors such as alcohol drinking, smoking, lack of exercise etc., are strongly associated with mental stress. Thus, in this review, we focus on the relationship between cortisol and lifestyle.The present findings suggested that lifestyle factors; smoking, alcohol drinking, exercise, sleep and nutrition are strongly associated with cortisol levels, and it may be impossible to determine whether alterations in cortisol levels are due to mental stress.It was suggested that those lifestyle effects on not only mental stress itself but also cortisol levels should be considered, when assessing mental stress by cortisol levels.
