This NSCA Coach article provides a proposes a framework for standardizing SEB resistance training based on principles of kinetic and potential energy. Visit NSCA online to read more on exercise science and sport performance.

This infographic briefly reviews the differences in sprint velocity and technique, including stride length and hip, knee, and ankle flexion during a 20-meter resisted sprint.

The purpose of this article is to review various gravitational running (GR) techniques from an evidence-based approach, then recommend whether to include GR techniques in the training of tactical athletes.

This article examines using the sled as a dynamic correspondence exercise for increasing on-ice acceleration.

Acceleration and maximal velocity are two factors that are key for any position in football and can determine success in many situations out on the field. This article will review several aspects of sprint mechanics and training to enhance linear (straight-ahead) speed for football players.

This article will examine the physical demands of soccer players and discuss why repeated sprint ability (RSA) is considered highly important in the performance of these athletes.

This article features the recharge skate—an in-season hockey conditioning drill, designed by the authors, to maintain hockey-specific energy system fitness throughout the competitive season.

This article discusses the influence of lower-body power on soccer performance in collegiate female soccer players. It also covers testing for muscular power qualities, different training modalities to use, and sample training programs as examples.

Sprinting is a key component for many individual and team sports. Therefore, to enhance sprint performance, various training methods are widely used by coaches and practitioners, including maximum sprint speed and resisted sprint training. Resisted sprinting with sled towing is a method that has recently received considerable attention from the sport science community. However, to date, no consensus exists regarding its acute and chronic effects in team sport athletes. This narrative review aimed to (a) review and analyze the mechanics of sprinting under unresisted and resisted conditions with a specific focus on team sport disciplines; (b) provide a thorough and applied discussion on the importance of considering acute and chronic effects of sled loading on technique, electromyographic activity, and force production, as well as on the role of muscle architecture and neural factors in sled training; (c) analyze the effects of increasing sled loads during acceleration and maximum velocity phases on contact and flight phases, while concomitantly examining kinetic, kinematic, and neuromuscular aspects, because all these factors affect each other and cannot be properly understood in isolation.

This article seeks to provide some insight to optimal biomechanics in running technique and why normal gravitational techniques may not suit tactical athletes while load-bearing.
