Repeated sprint ability (RSA) may be one of the most important factors to consider when developing strength and conditioning programs for high-intensity repeated sprint sports. In this session from the NSCA’s 2016 Coaches Conference, Ernie Rimer reviews the latest science behind RSA, compares the pros and cons of RSA protocols performed in the laboratory and in the field, and suggests methods to improve RSA.

Mike Snowden, University of Alabama Men’s Basketball Strength Coach, talks to the NSCA Coaching and Sport Science Program Manager, Eric McMahon, about having a genuine relationship with head sport coaches. Topics under discussion include building players into the program, creating buy-in, and embracing new and unique career opportunities.

Female athletes in the United States have made great progress in sports since Title IX was enacted in 1972. Despite the progress they have made, female athletes have yet to gain full recognition for their athleticism and their achievements. The purpose of this article is to break down the stigma female athletes have received over the years and shine light on the differences that make female athletes a reward to train.

Is the squat or hip thrust a better exercise for increasing jump and sprint performance? The results of this study support the force vector theory.

From the 2021 NSCA National Conference, Dr. Abbie Smith-Ryan discusses updated information, nutritional components, sex-specific considerations, and practical applications of high-intensity interval training.

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.
