Periodization of training is based on the principle that different loads (e.g., light, moderate, or heavy) or power requirements recruit different types and numbers of motor units. Recruitment order is important from a practical standpoint for several reasons.

This infographic shows the effects of sprint specific training, both forward and backward, and its relation to speed and power output.

With the average investment for personal training being $200 per client per month, professional personal trainers have the potential to earn over $100,000 a year if they apply themselves appropriately.

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.

Do interlimb asymmetries impact performance and what are some training programs to reduce them?

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.

Learn about the unique culture that comprises tactical performance, to include the unit-specific subcultures within it, and how to adopt both intuitive and research-based methods to more strategically impact military personnel. In this session from the NSCA’s 2016 TSAC Annual Training, Nate Palin explains effective and ineffective approaches to influencing the physical training within a tactical setting.

Learn about Loren Landow’s philosophy-based system of multidirectional training and explore how to best integrate multidirectional training to straight-line speed performance through a full progression of bilateral and unilateral exercises. In this session from the NSCA’s 2017 National Conference, Landow addresses the factors that influence agility with special attention to the feet and hips

This article looks at the movement patterns of downhill skiing and suggests strength and conditioning exercises for the recreational downhill skier.

This excerpt from Developing Agility and Quickness provides a needs analysis for field hockey and possible program design options for optimal performance outcomes.
