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.

Nearly all fitness professionals are forced to address low back pain (LBP) to some extent, regardless of the age or population with which they work. The purpose of this article is to shed light on contemporary research surrounding LBP.

Should personal trainers include the crunch exercise in an exercise program? The answer should always be, “it depends;” however, arriving at the best answer requires a process.

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 focus on three common areas of injuries that occur with ice hockey players and some recommended strategies for the strength and conditioning professional.

This article examines why the Romanian deadlift (RDL) provides a suitable in-season strength training application, explores the interlinked relationship between the demands of practice and resistance training, and identifies how the RDL functions with other lower-extremity exercises.

There are many factors, both personal and environmental, that play a role in the success of a training and diet program for an individual client. This article looks at the factors to be aware of and some solutions to finding the best fit program for an individual client.

This TSAC Report article examines the primary risk factors contributing to shoulder pain in tactical athletes and provides evidence-based rehabilitation strategies. Visit NSCA online to learn more about exercise research for tactical athletes.

Almost all functional movements of the trunk are combinations or variations of four basic movement patterns: trunk flexion, trunk extension, trunk rotation, and trunk lateral flexion. This article lists exercises to address each of these movement patterns.

This continuing education opportunity explores a variety of topics as they pertain to exercise technique. To earn your CEUs, it will be necessary to review several articles and pass a 50-question quiz. Please note: this quiz awards 1.0 CEU (10 contact hours).
