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

Colorado Springs, CO – MAJ Donald Bigham and Mark Stephenson named the 2017 TSAC-Facilitator and TSAC-Practitioners of the Year at NSCA’s TSAC Annual Training April 3-6, 2017 in Orlando, FL.

This article is part of a continuing series of tactical strength and conditioning (TSAC) research reviews. It is designed to bring awareness to new research findings of relevance to tactical strength and conditioning communities.

This article discusses the importance of upper body power training for protective security personnel and its potential for an occupational performance marker.

Bobby Smith, Owner and Director of Sports Performance at Reach Your Potential Training (RYPT), explains his systematic approach to writing a warm-up by implementing mobility, stability, activation, and injury prevention in this session from the NSCA’s 2018 National Conference.

World renowned Olympic training coach, Dan Pfaff, discusses how coaches can become a better performance supplier when managing athletic injuries. Pfaff also explains how to reduce lost time in practice and competitions, as well as how to reduce acute and chronic injury factors.

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.

NSCA has a network of volunteer leaders who direct NSCA’s efforts at the state and provincial level. NSCA’s Great Lakes Regional Coordinator provides oversight and training to local state and provincial directors. Members in the Great Lakes Region can connect at local and regional events as well as on Facebook to others in this area.

To apply performance enhancement and injury prevention practices employed by today’s professional and collegiate athletics to the Army, a restructuring of training paradigms needs to be implemented across the force.
