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.

Various aspects of resistance training, such as specific exercises chosen, workout structure, resistance used, volume (repetitions and sets), rest intervals between sets, and training frequency, can be manipulated to mold the strength training program to best meet an endurance athlete’s goals.

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.

This excerpt explains the role that lactate plays in exercise metabolism and how that information is useful for athletes to predict things like pacing, fitness, and efficacy of training programs.

This article discusses baseball-specific strength and conditioning techniques, focusing on lower extremity training and improving shoulder mechanics.

This article provides essential guidelines for athletes beginning a strength and conditioning program that ensures safety and productivity of the training sessions.

The aim of this article is to provide an overview of the research on multi-ingredient pre-workout supplements (MIPS) and help practitioners become educated consumers when evaluating the various formulas and products on the market for making recommendations to clients or athletes.

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.

This excerpt from the Essentials of Strength Training and Conditioning outlines what training typically looks like in the preparatory period, or off-season.

A qualified strength and conditioning professional in the high school environment can benefit both the school and the students in a number of ways, including injury reduction, improved performance, and risk management.
