The goal of this article is to define some of the basic physiological responses to acute and chronic altitude exposure and to provide some evidence-based, practical guidelines when approaching training and racing at higher altitudes.

The purpose of this article is to help bring awareness of athletic recovery by useful fatigue monitoring and managing tools, such as external and internal load examples.

This article shares various options for integrating mental skills training into existing strength and conditioning programs. Such simultaneous, dual-training approaches may better prepare officers for the realities of occupational performance.

High-intensity strength training paired with explosive, high-velocity movements is suggested to enhance endurance performance. It is recommended that a practical approach be taken when implementing this model of strength training, which would involve a thorough preparatory period.

This article reviews the basics of the Olympic lifts, including strength base, skill transfer, snatch progressions, and clean and jerk progressions. This article also covers several suggested practices for strength and conditioning coaches to fine-tune and progress learning and coaching of the lifts.

This article discusses the importance and impact a qualified fitness professional on the fitness and readiness of soldiers for the United States Army.

This article covers commonly used terminology from United States of America Weightlifting (USAW), plus it contains illustrations of the basic positions for weightlifting exercises.

This excerpt provides a brief snapshot of the use of carbohydrates in resistance training exercise sessions.

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.
