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.
Dr. Allison Randall, Strength and Conditioning Coach for the Vanderbilt University Women’s Basketball Program, talks to the NSCA Coaching and Sport Science Program Manager, Eric McMahon, about how her path to the 2012 London Olympic Games as an athlete led her to pursue the strength and conditioning profession. Topics include the use of appropriate cueing strategies to optimize work with young athletes, differences with team versus individual sports, and the importance of education for coaches.

Consumption of dietary protein by athletes is a common intervention to maximize gains in muscle and strength, and to improve body composition. The purpose of this article is to analyze the current research on the optimal amount of dietary protein for resistance training athletes.
Learn how to recognize and treat muscle dysmorphia in your athletes. In this session from the NSCA’s 2017 Personal Trainers Conference, James Leone covers many facets of athlete muscle dysmorphia, including the clinical features, identifying at-risk populations, using assessment tools, managing athletes suspected of having muscle dysmorphia, and how to treat it using a team-based approach.

There is a sound theoretical rationale supporting a potential role for muscle damages in the hypertrophic response, but a cause-effect relationship directly linking these gains to muscle damage is yet to be established. If such a relationship does in fact exist, it is not clear as to what extent of damage is optimal for inducing maximum muscle growth.
