This is an excerpt from NSCA's Essentials of Sport Science by NSCA -National Strength & Conditioning Association, Duncan N. French & Lorena Torres-Ronda.

Isolated muscle training methods do not necessarily transfer to better sports performance, because technique as well as strength contributes to successful performance. Resistance training for dynamic sports must involve ground-based movements that incorporate the coordinated stabilizing and dynamic functions of multiple muscles.

This article considers some of the main differences between the training of Olympic weightlifters and the use of Olympic weightlifting exercises in strength training for sport.

Exercises performed in the water that improve swimming skills and simultaneously work the core can be beneficial for swimmers. One particularly useful core exercise that is specifically designed for swimmers is a kickboard progression, such as the one described in this article.

The NSCA-CPT Techniques of Exercise Online Practice Question Bundle helps candidates get familiar with the type, scope, and difficulty of the questions on the NSCA-CPT Certification exam.

Strength and conditioning coaches can help bridge the gap between research and anecdotal experiences by reporting subjective and objective information obtained while carrying out everyday responsibilities.

This article provides medicine ball exercise progressions to help build athleticism in youth athletes.

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.

When choosing whether to purchase new technological advances, strength and conditioning coaches should consider price, practicality, and credibility in order to maximize the training of their athletes.

Nicole Rodriguez always knew she wanted to pursue strength and conditioning, but the extent of her journey — spanning 44 countries and the Paris 2024 Olympic Games — is nothing short of inspiring. During her time at Mike Boyle Strength and Conditioning, Rodriguez recognized the value of experience and environment, later joining the EXOS International Program to coach globally. Eager to test her skills and help standardize coaching education, she sought out developing countries to advance their sport infrastructure. Rodriguez outlines key differences between U.S. and European approaches: while the U.S. excels in strength methodology, Europe enhances sport-specific application through tactical periodization. Additionally, she highlights Europe’s emphasis on rehabilitation and an “inverse relationship” between time in the weight room versus pitch-side with sport coaches. Rodriguez also describes her work with Poland’s Ministry of Sport and Tourism to pursue NSCA Global Chapter status, aligning with her passion for improving strength and conditioning education and implementation worldwide.
