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.

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.

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.

Acceleration and maximum speed are terms used in speed development programs, and when developing a program, it is vital to differentiate between the two. This allows coaches to target their training to the capacity most important in their own sport.

This book excerpt discusses how to maximize sprint quality during training sessions.

The purpose of this article is to describe the cause of hamstring injuries in sprinters and present a biomechanical intervention, or drill, that can be used to prevent hamstring injuries while transitioning sprint athletes toward the utilization of frontside mechanics.

This book excerpt from Developing Agility and Quickness describes the windows of opportunity in youth athletes to time progressions in speed and agility training with their biological and chronological development.

This excerpt from Developing Speed discusses the various start patterns that exist and how to include them in a speed development program.

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.

The use of conditioning activities at maximal and sub-maximal intensities can increase subsequent sprint speed. This infographic describes how individuals’ responses can differ and suggestions to optimize post-activation potentiation (PAP) methods.
