This article discusses the effects of instability on force and velocity throughout the body.

The countermovement jump (CMJ) is one of the most used performance assessments in strength and conditioning. Although numerous studies discuss the usability of different metrics in this test, this is often performed within the context of a specific aim. However, to our knowledge, no information currently exists providing practitioners with some over-arching recommendations on which metrics to choose when the purpose of using the test differs. This article discusses how the metrics selected to monitor during CMJ testing may differ when aiming to use it as a proxy for athletic performance, as part of neuromuscular fatigue monitoring, or as part of a test battery for return to performance in injured athletes.

Learn about the “Golden Age of Strength and Conditioning” from those who lived it. Former National Basketball Association (NBA) strength and conditioning coach, Chip Sigmon, joins retired longtime National Football League (NFL) strength and conditioning coach, Jerry Palmieri, on a journey back to the 1970s and 1980s. Sigmon and Palmieri share their experiences, mentors, and life influences that put them on a path towards meaningful strength and conditioning careers with the NSCA Coaching and Sport Science Program Manager, Eric McMahon. Hear how the book, The Golden Age of Strength and Conditioning was written to feature powerful stories of professional growth from the many who were there.

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

Ankle injuries are very common and their incidence potentially can be reduced or prevented if the person has a better sense of foot position if proper footwear is worn while exercising.

Learn about Loren Landow’s philosophy-based system of multidirectional training and explore how to best integrate multidirectional training to straight-line speed performance through a full progression of bilateral and unilateral exercises. In this session from the NSCA’s 2017 National Conference, Landow addresses the factors that influence agility with special attention to the feet and hips

This article provides a sample six-week lumbo-pelvic hip complex strengthening program with the intended goal of improving vertical jumping ability and landing mechanics without the addition of plyometric or jumping/landing drills.
