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.

This infographic details sprint profiling and reviews possible resistance training exercises that help along the force-velocity curve.

This infographic summarizes how varying sled-loads increase different characteristics of sprint performance in male high school athletes.

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 infographic highlights the use of an individualized load-velocity method to prescribe sled-push loads in young athletes.

This excerpt from NSCA’s Essentials of Sport Science describes strength as a velocity-dependent concept.

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 excerpt from NSCA’s Essentials of Sport Science briefly explains the force-velocity-power profile and how it can give strength and conditioning coaches a more holistic view of athletes.

This article aims to explain why integrating multiple tests such as Anaerobic Speed Reserve (ASR), Intermittent Fitness Test (IFT), and Maximum Aerobic Speed (MAS) can provide a comprehensive evaluation of soccer players’ fitness levels and help to design effective training programs tailored to their individual needs.
