One resistance training variable that may be altered to achieve desired outcomes is the range of motion used in training. Generally, the strength and conditioning field has accepted that using a greater range of motion in strength training exercises results in more substantial muscle hypertrophy outcomes. However, this theory has proved to be inconsistently supported in the literature, and to date, no sufficient explanation exists to explain this phenomenon. This review article seeks to outline a novel approach for potentially describing the disparities seen in range of motion research with respect to hypertrophy outcomes by applying the unique length-tension curve of each muscle being examined. As will be discussed in the review, virtually all the results from range of motion studies in various muscles have corresponded to each muscle’s length-tension curve; muscles that are active on the descending limb of the curve appear to garner greater hypertrophy from using larger ranges of motion. Conversely, muscles that are not active on the descending limb exhibit similar adaptations despite alterations in range of motion. A novel hypothesis for applying this information to resistance training programs will be presented and discussed.

This article provides a brief overview of literature where regional hypertrophy was reported. It also discusses the basic science and application of regional hypertrophy training.

This article discusses how personal trainers can utilize the strength zone training system in order to develop true full range of motion strength, and thus help clients perform better and further reduce injury risk.

Learn how to use sprinting as a means of screening athletes for power, strength, range of motion, and coordination. In this session from the NSCA’s 2018 National Conference, Derek Hansen also identifies appropriate sprinting and running mechanics for optimizing performance and minimizing injury, and outlines a process for using sprinting as a return-to-play modality for soft-tissue and joint injuries.

The purpose of this article is to provide personal trainers with a review of common muscle extensibility tests of the lower extremity.

This book excerpt reviews functional isometrics as a way to build strength at the weakest point in the range of motion.

The importance of recognizing a closed-chain activity lies in the fact that the motions of multiple joints are coupled. Weakness at any one joint will consequently limit performance of the entire movement.
