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 seeks to explain monitoring body composition, including how to assess it properly for an accurate evaluation to minimize errors in body fat estimation and maximize physical training.

This article provides personal insight and practical ways that mindfulness training can be incorporated into a physical training (PT) plan.

The following information provides an overview of what microdosing (MD) is, the limitations in utilizing it as a programming method, and the structure of an MD training session along with examples of in-season and off-season training microcycles.

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.

Much in the same way that a single movement or a single workout does not make or break a training cycle, the same holds true for mental skills. The challenge is that the strength and conditioning coach will likely need to reach out to another professional trained in sport psychology to help establish the plan and construct the appropriate interventions.

For those dealing with clients who have back pain, this article focuses on non-specific low-back pain and potential exercise solutions for it.

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.

The purpose of this article is to examine the critical role of core stability in soccer performance.

Most law enforcement officers are physically taxed, mentally exhausted, and emotionally overwhelmed. As such, a complexity exists with a requirement to match the need for physical fitness in a demographic that lives their lives in a potential state of general exhaustion.
