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.
Through a well-designed resistance training program, firefighter recruits can gain the movement skills, confidence to exercise, and foundational strength/physiological adaptations that they need for a long and healthy career.

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.
Consumption of dietary protein by athletes is a common intervention to maximize gains in muscle and strength, and to improve body composition. The purpose of this article is to analyze the current research on the optimal amount of dietary protein for resistance training athletes.
