The catecholamines—primarily epinephrine, but also norepinephrine and dopamine—are secreted by the adrenal medulla and are important for the acute expression of strength and power because the hormones act as central motor stimulators and peripheral vascular dilators to enhance enzyme systems and calcium release in muscle.
Growth hormone release is affected by the type of resistance training protocol used, including the duration of rest periods. Short rest period types of workouts result in greater serum concentrations compared to long rest protocols of similar total work; however, at present it is not clear how the various molecular forms or types of growth hormones are affected by rest period duration.
The purpose of this article is to help both personal trainers and clients with seven main concepts within exercise physiology that will improve training effectiveness and assist in explaining the body’s response to exercise.

Considering that the term "power" typically evokes the perception of high-speed movement, many people are inclined to take the tenets of specificity to literally mean “train fast, be fast.” However, to create the most strategic methods of training and adaptation, it is vital to compartmentalize power into the primary testable and trainable elements.

While acute inflammation is a normal response to high-intensity training, chronic inflammation results in depressed immunity and impaired muscle response. Learn about nutritional strategies to help balance exercise-induced inflammation to optimize performance outcomes.
