This infographic briefly reviews the application and training adaptations of eccentric quasi-isometric resistance training.

This excerpt describes plyometric training with regards to the stretch-shortening cycle.

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.

The evaluation, treatment, and management of concussions are an ongoing evolution in sports injury management and medicine. Strengthening the neck and shoulder region has been one way of trying to reduce head and neck injuries.

This article presents the shoulder taps, which could serve as a more time-efficient screening tool for tactical operators. Although this article will present the shoulder taps as an assessment modality, it may be expanded upon and prescribed as an exercise for the purpose of improving trunk, hip, and shoulder stability.

This article examines how training the core and performance are connected. This article seeks to help propose how to best use the literature to maximize understanding and use of the current concepts.

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.

Loren Landow shows some progressions for core training movements that he uses with his athletes.

This article aims to discuss concurrent activation potentiation (CAP) and the proposed mechanisms underlying it, summarize the available research examining the phenomenon, and provide strategies for its implementation.
