This article outlines some very basic procedures for video analysis that strength and conditioning professionals can use to identify the physical demands of specific activities.

This article explains the specific considerations of building a tactical training space and how to maximize the potential of the dedicated space by having a stable of equipment that reflects the needs of the audience.

Considering the great popularity of eccentric-based training, the purpose of this review is to first provide the scientific rationale for its use; second, summarize the eccentric-based training modalities that can be used; and finally, offer practical recommendations on how to implement eccentricbased modalities to enhance sports performance. The molecular and neural mechanisms underlying eccentric actions are partially distinct from those of concentric and isometric actions. During eccentric actions, theories suggest a strain-induced modulation of actin-myosin interactions at the crossbridge level, activation of structural protein titin, and winding of titin on actin. Eccentric acute physiological responses differ from concentric exercise responses, including variations in neuromuscular, metabolic, hormonal, and anabolic signaling. Eccentric training elicits greater improvements in muscle strength, power, and stretch-shortening cycle function compared with concentric-only or traditional resistance training. Therefore, eccentric-based training can lead to unique neuromuscular (e.g., improved coordination of motor units) and morphological (e.g., increased muscle fascicle length and enhanced distal cross-sectional area) adaptations that could play a key role in sport performance. Practitioners may implement eccentric exercises with external loads, fully eccentric-based exercises (e.g., Nordic hamstring curl), accentuated eccentric loading, flywheel resistance exercise, and plyometrics to develop specific physical adaptations in line with their goals. Eccentric work (e.g., for hamstrings) can be obtained during other exercises such as downhill running tasks, decelerations, and sprinting activities. Practitioners need to be aware that no single “silver bullet” training modality exists; consequently, practitioners should use a combination of eccentric-based training approaches with their athletes to obtain the desired adaptations.

The purpose of this article is to present pedagogical content knowledge to personal trainers aimed to enhance client performance and satisfaction.

There is growing momentum in the modernization of law enforcement (and other tactical populations) to integrate industry and academic institutions into modernization plans. Tactical Strength and Conditioning Facilitators® (TSAC-F®) can contribute to this collaboration.

This research review covers topics such as the effects of police officer equipment loads, military occupational specialties, and the effects of protective clothing and self-contained breathing apparatus for firefighters.

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.

This article seeks to help personal trainers understand the physiological effects of stress and helpful ways they can drive positive changes for their clients through exercise.

This Kinetic Select excerpt from the Essentials of Strength Training and Conditioning, Fourth Edition describes the results from electromyography (EMG) studies on the neural adaptations to anaerobic training.

The initial interview is the starting point for the client-trainer relationship and sets the tone for the emotional connection and the development of trust and value for a long-lasting professional relationship.
