This excerpt briefly describes the different energy systems used by structural and wildland firefighters.

With the need to be ready under any circumstances from operational missions to physical training, understanding how the adrenal gland functions is important for any tactical athlete. The adrenal gland mediates performance and can have a negative effect on the body’s physiology when exhausted. It is vital to understand the interventions needed to obviate the negative effects and enhance the positive aspects of such physiological function. This session from the 2015 TSAC Annual Training sheds light on this important physiological system that impacts both physical health and functional performance.

Isolated muscle training methods do not necessarily transfer to better sports performance, because technique as well as strength contributes to successful performance. Resistance training for dynamic sports must involve ground-based movements that incorporate the coordinated stabilizing and dynamic functions of multiple muscles.

This article explains Fartlek training as well as how it can be programmed and individualized for different clients.

This book excerpt reviews functional isometrics as a way to build strength at the weakest point in the range of motion.

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.

This article explains how having the right systems in place (such as accounting, training, and marketing) can help a personal trainer take his or her business to the next level.

In this 2018 coaches conference video Todd Hamer describes his experience working with collegiate football players, and his methods for targeting appropriate energy systems to increase athletic performance in speed and conditioning.
