Title | The Dynamic Strength Index: is it a useful tool to guide programming decisions? |

Abstract | How do I know if an athlete’s power output would be best enhanced by increasing their force or velocity capabilities? How do I know if an athlete would benefit most from increasing their peak force or their rate of force development (RFD)? These are two questions strength and conditioning (S&C) professionals will ponder when planning strength training to support athletic performance. The dynamic strength index (DSI) has been proposed as a diagnostic approach to help answer such questions. This article discusses the suitability of both the denominator (isometric peak force) and numerator (jump peak force) metrics, and the DSI ratio itself, to inform programming decisions. Drawing on biomechanical principles and research exploring the physiology of condition-specific strength, we outline its disputable underpinnings. Accordingly, alternative diagnostic tools are proposed. Together with an understanding of the specific constraints on force production within target sporting actions, these will in turn, help practitioners make the most informed decision on the best strength training approach to enhance their athletes’ physical performance. |
