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.

Tendinopathy is a pathological condition that occurs when a tendon is repeatedly injured and degenerately breaks down. Specific exercise programming may help prevent tendinitis from occurring.

This article provides a sample six-week lumbo-pelvic hip complex strengthening program with the intended goal of improving vertical jumping ability and landing mechanics without the addition of plyometric or jumping/landing drills.

No training program can completely eliminate the risk of cardiovascular disease or low back pain, but some steps can be taken to decrease the likelihood of being afflicted by either.

This article reviews electromyography (EMG) procedures as well as provides examples of how EMG data analysis has been used in tactical populations.

The article discusses the talent crisis that is currently plaguing United States first responders, public safety agencies, and military organizations, and concludes with highlights of select successful programs.

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.

This article is part of 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.
