Abstract

The results of the current study demonstrate that exercise interferes with the hormonal balance system. The size and direction of these changes depend on the volume and intensity of a physical effort. Biochemical monitoring can support the process of training and gathered data can assist in countering the effects of overtraining. The article presents the latest reports on the character of the changes in cortisol influenced by various types of physical effort, the impact of the training units, time of their execution and the influence of the supply of carbohydrates on the level of this hormone in the body. This work also presents the advantages of saliva analysis, as a reliable material to measure the level of cortisol in athletes.

The Neuromuscular, Biochemical, and Endocrine Responses to a Single-Session Vs. Double-Session Training Day in Elite Athletes

A speed-and-weights training session after a speed session increases muscle soreness but does not significantly affect endocrine response or neuromuscular capability in elite athletes.

Impact of physical fitness on salivary stress markers in sedentary to low-active young to middle-aged men

Physical fitness has a weak but significant impact on biological stress responses, with attenuated hypothalamic-pituitary-adrenal but slightly higher autonomic responses in fitter men.

Performance and Endocrine Responses to Differing Ratios of Concurrent Strength and Endurance Training

Higher volumes of endurance training inhibit lower-body strength, while low volumes do not, and both high and low frequencies of endurance training increase cortisol responses to training.

Salivary but not plasma cortisone tracks the plasma cortisol response to exercise: effect of time of day

Intense exercise increases plasma cortisone and corticosterone in both morning and evening, but salivary cortisone increases in the morning, suggesting a novel marker of free cortisol during exercise.

Impact of intensified training and carbohydrate supplementation on immunity and markers of overreaching in highly trained cyclists

Intensified training in highly trained cyclists led to symptoms of overreaching, but higher carbohydrate intake did not alleviate these physiological/immunological disturbances.
