Acceleration is the rate of change in velocity, so this phase of sprinting is critical for changing directions as rapidly and efficiently as possible. Optimal technique for linear sprinting in the acceleration phase involves four factors that maximize stride length and frequency.

NSCA awards are governed by this following general criteria. Please visit the individual award's page for specific criteria.

The hip hinge and squat exercises, and their variations, are used in many strength and conditioning programs to develop athletes of many sports. The listed progressions are examples of practical implications used to develop athletes, but there may be additional practical and effective methods used by strength and conditioning coaches for similar purposes.

Strength and conditioning professionals who incorporate a properly designed and supervised training program can help their young athletes train, compete, and reduce the likelihood of injury.

This article provides the first academic history of the barbell back squat and its evolution from a bodyweight exercise in the 19th century to a loaded exercise used for a variety of purposes in the present age. In doing so, the article highlights three key drivers in the evolution of the back squat—changes in equipment, the diversification of strength sports, and scientific communication concerning the safety and efficacy of the movement. The goal of this article was not to provide a dry and irrelevant history but rather to stress the complexity of the squat’s prominence within fitness programs and the need to hold a nuanced view toward the “optimal” way to approach this movement. It examines how the movement evolved from being primarily done on the tips of one’s toes, to a loaded movement on tippy toes, to a flat-footed movement. By contextualizing the back squat’s history, this article challenges rigid notions of “correct” squatting technique and encourages a more nuanced understanding of exercise selection in strength and conditioning practice. It concludes by highlighting the importance of critically examining the social construction of knowledge in fitness and sport, and the value of historical perspective in informing contemporary training practices

There are inherent challenges to designing training programs for firefighters, Mark Abel says in this member-only lecture from the 2014 TSAC Conference. Join Mark as he provides valuable insight into programming for these tactical athletes, including appropriate periodization and training strategies that address these challenges.

The National Strength and Conditioning Association (NSCA) announces the results of its 2024 Elections, as selected by NSCA Members. These chosen individuals, nominated for their dedication and contributions to the NSCA and professional community, will help shape our future and further our mission to advance strength and conditioning research and education.

The NSCA has built a collection of resources to help our community of strength and conditioning professionals and athletes safely return to training and adapt to the new challenges created by the COVID-19 (coronavirus) pandemic.

Athletes in field and court sports require reactive agility—they must accelerate, decelerate, and change direction in a constantly changing environment. These requirements result in technical differences between sprinting in a field or court sport and sprinting the 100-m.

As the second of a three part series, this article will focus on the Practitioner Pillars of LTAD, including relevant monitoring and assessment tools, as well as systematical progressions and individualized training programs for successful long-term physical development.
