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 excerpt from NSCA’s Essential of Tactical Strength and Conditioning explores the neural and muscular adaptations to training over time.

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.

Military and law enforcement needs analyses are not specifically matched to firefighting, but those training styles are better than basic fitness regimens or no regimen at all. For firefighters who are attracted to other styles of training not specific to firefighting, there are ways to train for all the demands of firefighting without making the firefighter use training modalities that they dislike or are not comfortable using.

This article provides strength and conditioning coaches with strategies to address hip mobility limitations that may lead to lumbar spine and femoral acetabular issues.

This article is the sixth in a continuing series of tactical strength and conditioning (TSAC) research reviews. It is designed to bring awareness to new research findings of relevance to tactical strength and conditioning communities.
