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.

In this 2018 NSCA Personal Training Conference video, Mike Israetel describes how to create and develop motivation in your clients, and how to understand the process of motivation in people.

This article aims to explore why unloaded non-linear training can be an effective modality for personal trainers, strength coaches, and exercise enthusiasts, as well as present the benefits, possible implications, and methods that can be implemented into a current training program.

The purpose of this article is to define the roles of personal trainers and physical therapists and to learn how their combined expertise can influence long-term physical health improvements for their clients.

Finding a well-educated and open-minded employee is, in most cases, simply luck of the draw. Instead of hoping for the perfect new hire to come walking through the door, a business owner could try a different technique in which they shed their business owner mindset and transition into a mentorship role. Using an internship program, the mentor can ideally build themselves the near-perfect employee.

The National Strength and Conditioning Association is proud to work with our outstanding partners and thank them for their continued support.

Strength and Conditioning Coaches who are NSCA-Certified are preparing youth for training, using proven strategies that improve their safety and competitiveness.

Nutrition plays an important role in the injury prevention and treatment of tactical professionals. Nutritional goals for healthy connective tissue are twofold: increase collagen content in connective tissues susceptible to injury and prevent a decline in collagen content to help mitigate injury and facilitate recovery.

Competence, autonomy, and relatedness are three keys to promoting a more intrinsically motivated athlete. These components can be combined in nearly limitless ways, which is especially important for the long basketball season.

Although most resources on program design review the foundational scientific principles of training, they often fail to provide practical strategies that strength and conditioning professionals need in order to apply these principles successfully. To help bridge the gap between science and application, this article provides a simple and practical, step-by-step system for applying the scientific principles of training into the program design process.
