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.

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.

The purpose of this article is to provide some actionable topics for communication that can increase the frequency and effectiveness of communication for strength coaches with their sport coaches.

Colorado Springs, CO – The National Strength and Conditioning Association announces that Eric McMahon, MEd, CSCS, RSCC*D, has been named the organization’s new Coaching Program Manager. In this role, McMahon will represent professional, collegiate, high school, and private sector coaches who are part of the NSCA’s community. In addition, McMahon will work with leaders in the field to advance the coaching profession, evaluate existing NSCA resources and programs, and provide new resources to better serve coaches and their needs.

Ankle sprains are an extremely common injury of both sports and everyday life. In the post-rehabilitation setting, it is important to first identify and then address deficits in ankle, hip, and knee range of motion and strength.

The purpose of this article is to provide personal trainers reading the strength and conditioning research the knowledge necessary to better understand the statistical data commonly reported in research manuscripts.
