This excerpt from Developing Speed looks at how a fundamental understanding of the biomechanical principles that affect speed can assist coaches and athletes in developing running speed.

This info-graphic describes research on velocity decrements to increase propulsive and horizontal force applications to increase acceleration kinetics.

Matthew Ibrahim, Co-Owner of TD Athletes Edge, talks to the NSCA Coaching and Sport Science Program Manager, Eric McMahon, about using setbacks as a learning opportunity. Topics under discussion include creating a holistic approach to a client’s training by collaborating with other professionals, and the importance of deceleration technique and eccentrics in his programs for skill acquisition.

Guy Leahy writes a review of the research relating to the tactical population from presentations and research from the 65th Annual Meeting of the American College of Sports Medicine (ACSM).

This article provides a practical framework for implementing velocity-based training (VBT) in the college football setting, including strategies for autoregulation, load monitoring, training specificity, and the development of strength and power.

The purpose of this article is to provide an introduction to contrast training, including how it is defined, what variables are utilized, and examples of how to use it in training.

Elite sport often gets more attention, but youth training gives strength and conditioning coaches an earlier chance to build athletes’ competence and confidence. Kelli Brightwell specializes in youth development and brings more than a decade of sports training experience, including four years at Michael Johnson Performance. Brightwell defines peak height velocity as the period during which height increases fastest. She then explains why its timing can differ among teammates of the same age. So what should strength coaches test, and what do the results mean? The answer changes with each athlete’s maturity and training experience. Brightwell addresses the growth-spurt “awkward phase,” when familiar movement patterns can break down as an athlete adjusts to a changing body. She also considers how sport sampling can expand children’s range of physical skills and help them discover what they enjoy. Learn how maturation can affect movement, testing, and programming — and why young athletes need foundations before specialization.

Approximately 2 million youth from 6 - 12 years of age participate in football every year. This article discusses the importance of long-term athletic development (LTAD) for youth football athletes and the significance of a player development pathway for long-term success and longevity in the sport.
