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.

Sporting nine national championship rings, Coach Andrea Hudy stands as a titan in strength and conditioning. She joins co-hosts NSCA Coaching and Sport Science Program Manager Eric McMahon and Gatorade Team Sports Manager Jon Jost to reflect on her journey, including pursuing her PhD and the impact of lifelong learning. Together, they discuss the changing collegiate landscape, now resembling a professional environment with holistic, interdisciplinary collaboration. Hudy explains how early specialization may expedite later-career injuries, inspiring her to investigate gait mechanics. Name, Image, and Likeness (NIL) policies also mean a “bigger pot” for athletes, extending collaboration to agents and scheduling. They theorize collegiate athletes may face more stressors than professional athletes due to their academic schedule, training, and promotional travel — making time management and investing in longevity essential. Hudy describes her philosophy of education, motivation, and communication, built upon a foundation of honesty and healthy relationships. The trio examine the evolving strength coach skill set, including sport science elements, before offering advice for aspiring professionals.
