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 will discuss why it is important for first responders to have abdominal and lumbo-pelvic strength in relation to movements and tasks in their specific jobs. A list of possible exercises and implementation are also included.

This article aims to explain why integrating multiple tests such as Anaerobic Speed Reserve (ASR), Intermittent Fitness Test (IFT), and Maximum Aerobic Speed (MAS) can provide a comprehensive evaluation of soccer players’ fitness levels and help to design effective training programs tailored to their individual needs.

Isolated muscle training methods do not necessarily transfer to better sports performance, because technique as well as strength contributes to successful performance. Resistance training for dynamic sports must involve ground-based movements that incorporate the coordinated stabilizing and dynamic functions of multiple muscles.

The aim of this article is to highlight the functional importance of the foot, and to provide recommendations for foot conditioning.

The purpose of this article is to propose a training model for the aging firefighter to improve the athletic qualities of aerobic fitness and muscular strength so that they may remain healthier longer into their careers.

Boyd Epley, founder of the National Strength and Conditioning Association (NSCA) and one of the most decorated strength coaches of all time, talks to the NSCA Head Strength and Conditioning Coach, Scott Caulfield, about how the NSCA was founded, how Coach Epley talked Nebraska into letting him weight train all football athletes (most of whom never lifted before), and growing the profession for female strength and conditioning coaches.
