The purpose of this article is to explore trauma-related mental health issues and help human performance professionals more effectively train tactical athletes.

The purpose of this article is to examine components that affect speed to determine the degree that speed is governed by skill versus genetic factors.

This article briefly explains the two principles necessary for muscle growth.

This article briefly reviews the importance of the stretch-shortening cycle in power production.

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 squat is one of the most essential movements in life and performance. In this Bridge video, Mandy Nice goes over the proper progressions for individuals to successfully and safely perform the squat.

In this article, three considerations are discussed to aid in addressing successful rehabilitation and return to work: 1) targeting the injury site using a combination of physiotherapy, physical therapy, and tactical strength and conditioning; 2) workplace engagement; and 3) using available tools that may assist in determining appropriate approaches.

What training approaches are efficient and effective at developing functionality and resiliency at the core? The answer lies within an intelligent, systemic, multi-method approach to training the core, including an eclectic set of training tools to individualize specific needs of athletes.

This article provides a few key tips on how to perform the deadlift more efficiently and safely. Some helpful coaching cues—such as keeping the head slightly up, activating the lats, and pushing the knees out—can assist a tactical athlete in executing the deadlift while increasing strength over time.

Tactical facilitators need to understand the movement patterns that first responders encounter because they can have a profound effect on underlying biomechanics and may contribute to excessive tissue loads.
