This article focuses on a program for a Paralympic athlete born with a congenital limb deficiency (transradial peromelia) of the right arm.

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.

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.

Providing a safe and effective youth strength and conditioning program is only the foundation of their long-term athletic development.

Recent advances in research and human performance programs (HPP) has made it possible to learn more about the tactical athlete while creating enhanced methodologies and implementation. This review draws on the past three years of research focusing on strength and conditioning within military communities, exploring the current themes of research and the implications of future studies.

Strength and conditioning coaches can safely and effectively integrate strongman training into youth strength and conditioning programs by following established programming guidelines and available research recommendations.

The purpose of this article is to make the case for implementing non-traditional sports into training programs that prepare youth for participation in traditional American sports and bridge the gap between pedagogy of physical education and strength and conditioning youth coaching.

The “five Ss” of trainability and performance are critical periods of development that all youth strength and conditioning coaches should consider when creating a training program. Coaches should take advantage of each window to maximize a youth athlete’s potential and help ensure a long athletic career.

This excerpt from NSCA's Essentials of Tactical Strength and Conditioning aims to educate on some fundamentals of energy systems training in tactical personnel.

The purpose of this article was to conduct a process evaluation of a six-week recruit strength and conditioning programming for rural structural firefighter recruits.
