Developing safe and effective exercise training programs requires the application of abundant training variables and the implementation of appropriate progression for each variable. Importantly, the outcomes of each training program are the product of these variables and their progression, so practitioners are keen to select methodologies and overload strategies that effectively support their target training outcomes. One such training variable is mechanical loading, which describes the forces of gravity, resistance, and muscle contraction and how these forces affect musculoskeletal adaptations. Numerous research articles and texts have been published regarding mechanical loading and its effects on exercise adaptations; however, these findings can be arduous to organize, which requires additional time investment by professionals. Developing a succinct system is critical because practitioners face clients and patients with a wide range of physical skills and challenges, and having an easily referenced loading guide may assist them in designing appropriate strength and conditioning or rehabilitation programs. Thus, the purpose of this review is to define and describe the mechanical loading continuum and its individual components to better assist the practitioner in identifying appropriate exercise modes and progression strategies.

This infographic reminds coaches of the importance of in-season strength training programs for maintaining physical capabilities and sport performance, while decreasing the overall risk of injuries in athletes.

This excerpt from NSCA’s Essentials of Sport Science highlights the importance of quantifying training load for both programming and monitoring an athlete’s progression or regression over time.

Rushing into administering a training program can greatly hinder long-term gains for the client. This article explains the key components of the client interview, or as it is commonly referred to, “success session.”

The purpose of this article is to help both personal trainers and clients with seven main concepts within exercise physiology that will improve training effectiveness and assist in explaining the body’s response to exercise.

Dietmar Schmidtbleicher, Head and Chair for Sport Sciences at the Institute of Sport Sciences at the Goethe University Frankfurt/Main in Frankfurt, Germany—and one of the world’s leading experts on strength and power training—explains the influencing factors of force production in eccentric muscle actions. Schmidtbleicher made a rare appearance in the United States at the NSCA’s 2015 National Conference.

In this session from the NSCA's 2016 National Conference, Boo Schexnayder demonstrates how to effectively design long-term and short-term programs for speed development. Schexnayder explains how to effectively periodize strength training in a manner that supports speed development, as well as how to use speed and power training as a neural integration tool to enhance strength development.

Between the physiological, cognitive, and tactical skill demands, this article explains why fighter pilots should be considered tactical athletes and have access to resources like a professional sport athlete.

Examine different measures of velocity that can be used in resistance training and understand how each measure may be more applicable to either strength or power exercises. In this session from the NSCA’s 2016 National Conference, Daniel Baker, President of the Australia Strength and Conditioning Association, explains how to use velocity data to monitor changes in strength or power, and how to use velocity scores for readiness/performance monitoring.
