This article discusses the importance of resistance training for older adults and considerations that personal trainers need to be aware of when working with this population.

The goal of this article is to overview the most evidenced-based recovery strategies that are promoted in United States Air Force Special Warfare.

This article seeks to provide a sample periodized program plan that will progress wrestlers for multiple years while considering the diverse individual needs and weight class-specific goals.

This Kinetic Select excerpt from the Essentials of Strength Training and Conditioning, Fourth Edition describes the results from electromyography (EMG) studies on the neural adaptations to anaerobic training.

The purpose of this article is to present normative data that has been previously collected for the 75PR, use the data to create informed training practices, and support the need for further research of this particular topic in law enforcement.

Factors such as the types of exercises used, the number of muscle groups trained per session, the structure of the program, and the client’s training status and overall fitness level dictate training frequency.

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.

This article discusses the background, statistics, mechanisms, timing, dosing, influences, and practical applications for the use of caffeine as an ergogenic aid.

This article focuses on interprofessional collaboration for optimizing athlete return to sport (RTS).

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.
