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.

From the 2023 NSCA Tactical Annual Training, Ian Bonder and Andrew Shim review micro-dosing programming strategies and benefits for the tactical population.
Built on scientific principles and evidence-based research, the NSCA’s Tactical Strength and Conditioning (TSAC) Practitioners Course is a foundational strength and conditioning program designed to provide tactical facilitators with the tools to decrease injury risk and increase longevity and effectiveness of tactical professionals.
Nontraumatic shoulder disorders are prevalent among weight-training participants
as a result of training patterns as well as adaptive shoulder joint and muscle characteristics. This article presents a progressive approach to exercises designed to mitigate well-known joint and muscle characteristics that have been associated with shoulder disorders. Using a progressive evidence based model, practical applications are presented that will guide sports medicine and strength training professionals in their ability to provide an evidence informed upper extremity weight-training program for both patients and clients.
Blood pressure changes acutely during resistance exercise. Continuous, beat-by-beat assessment provides detailed temporal resolution of blood pressure profiles, through techniques including intra-arterial catheterization, photoplethysmography, or applanation tonometry. However, noncontinuous measurements may be conducted before and after resistance exercise through auscultatory sphygmomanometry or oscillometry. Blood pressures tend to increase across repetitions within sets, influenced by load magnitude, repetitions and sets performed, muscle mass recruited, and rest periods; the highest pressures result from multi-joint, large muscle group exercises. Evaluation of such factors may facilitate better understanding of blood pressure responses to acute resistance exercise and influence program design considerations relative to anticipated hemodynamic changes.
