The aging athlete and office worker are both being cramped into body positions that not ideal. People in these situations could greatly benefit from some daily exercises to perform to overcome these issues. In this hands-on session, attendees will be given some simple movements that can be adapted for anyone and any situation.

Some of the major misconceptions concerning Olympic-style weightlifting for sport are addressed in this article, providing evidence-based recommendations to better implement the snatch, clean and jerk, and their derivatives in the training of high school and collegiate athletes.

Through a well-designed resistance training program, firefighter recruits can gain the movement skills, confidence to exercise, and foundational strength/physiological adaptations that they need for a long and healthy career.

Approximately 2 million youth from 6 - 12 years of age participate in football every year. This article discusses the importance of long-term athletic development (LTAD) for youth football athletes and the significance of a player development pathway for long-term success and longevity in the sport.

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 infographic briefly reviews the application and training adaptations of eccentric quasi-isometric resistance training.

This is the second part of a two-part series that investigates the effects of dietary carbohydrate availability on exercise performance and how specifically timed restriction of carbohydrates may also paradoxically enhance exercise performance in the medium and long term.

This excerpt from NSCA’s Essential of Tactical Strength and Conditioning explores the neural and muscular adaptations to training over time.

This article discusses the idea of Confucian adaptability as a framework for cultivating interpersonal skills for personal trainers.
