This infographic explains how to build a load-velocity profile for velocity-based training (VBT), and is the second of a three part series explaining the theory behind and application of VBT.

Dr. Tim Suchomel, Assistant Professor at Carroll University and Wisconsin State Director for the NSCA, talks to the NSCA Coaching and Sport Science Program Manager, Eric McMahon, about the emerging role of sport science in strength and conditioning. Topics under discussion include Suchomel’s growing involvement with the NSCA, as well as weightlifting derivatives and their benefits for more individualized performance adaptations.

Two factors that determine running speed are stride cadence and stride length. Because athletes propel themselves forward only when their foot is in contact with the ground, the stance phase of the running stride should be the focus of speed enhancement programs.

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

Some of the major misconceptions concerning Olympic-style weightlifting for sport are addressed in this article, providing evidence-based recommendations to better implement the snatch, clean and jerk, and their derivatives in the training of high school and collegiate athletes.

Tim Suchomel, Assistant Professor of Exercise Science and the Program Director for the Sport Physiology and Performance Coaching graduate program at Carroll University, discusses the literature surrounding the force-velocity curve, identifies potential periodization and programming strategies to improve these characteristics in athletes, and provides example programs to show how to implement different resistance training methods.

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

Velocity-based training (VBT) is a contemporary method of resistance training that enables accurate and objective prescription of resistance training intensities and volumes. This review provides an applied framework for the theory and application of VBT. Specifically, this review gives detail on how to: use velocity to provide objective feedback, estimate strength, develop load-velocity profiles for accurate load prescription, and how to use statistics to monitor velocity. Furthermore, a discussion on the use of velocity loss thresholds, different methods of VBT prescription, and how VBT can be implemented within traditional programming models and microcycles is provided.

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.
